A fruit and vegetable dryer in case of failure can bring a lot of grief to any housewife. If the dryer does not heat up, do not throw it away and run to the store for a new one. Today we will try to eliminate one of the most common malfunctions in fruit and vegetable dryers. Repair of a vegetable dryer, as practice shows, can take 15-20 minutes of free time. Go!

Drying Vinis was admitted with symptoms: "The dryer does not heat." This is not expensive drying and the breakdown that caused this problem should be solved simply, there is practically nothing to break.

We disassemble the drying and check the integrity of the heating element.

The open-type heating element is visually intact, the continuity of its conclusions confirms this. Before the heating element, a thermal fuse is included in the circuit, which must also be checked.

As practice shows, it is often thermal fuses or heating elements that are the culprits of such symptoms. In our case, the thermal fuse is faulty.

Instead of a thermal fuse, you can put a jumper and check the drying performance. If everything works fine and the heating element does not overheat, you can blame it all on a poor-quality thermal fuse.

If the air flow is clearly weak and the heating element starts to overheat, then it is worth doing prophylaxis for the fan motor. Just a couple of drops of engine oil on felt gaskets near the bushings can reduce friction in the bushings of the engine and increase the speed of rotation of its blades. Decreased engine speed can also provoke overheating of the heating element and failure of the thermal fuse.

Video (click to play).

After all the manipulations, the jumper can be replaced with a new thermal fuse and dried.

Is your TV, radio, mobile phone or kettle broken? And you want to create a new topic about this in this forum?

First of all, think about this: imagine that your father / son / brother has an appendicitis pain and you know from the symptoms that it is just appendicitis, but there is no experience of cutting it out, as well as the tool. And you turn on your computer, access the Internet on a medical site with the question: "Help to cut out appendicitis." Do you understand the absurdity of the whole situation? Even if they answer you, it is worth considering factors such as the patient's diabetes, allergies to anesthesia and other medical nuances. I think no one does this in real life and will risk trusting the life of their loved ones with advice from the Internet.

The same is in the repair of radio equipment, although of course these are all the material benefits of modern civilization and in case of unsuccessful repairs, you can always buy a new LCD TV, cell phone, iPAD or computer. And for the repair of such equipment, at least it is necessary to have the appropriate measuring (oscilloscope, multimeter, generator, etc.) and soldering equipment (hairdryer, SMD-hot tweezers, etc.), a schematic diagram, not to mention the necessary knowledge and repair experience.

Let's consider the situation if you are a beginner / advanced radio amateur who solders all sorts of electronic gizmos and has some of the necessary tools. You create an appropriate thread on the repair forum with a short description of “patient symptoms”, ie. for example “Samsung LE40R81B TV does not turn on”. So what? Yes, there can be a lot of reasons for not switching on - from malfunctions in the power system, problems with the processor or flashing firmware in the EEPROM memory.
More advanced users can find the blackened element on the board and attach a photo to the post. However, keep in mind that you replace this radio element with the same one - it is not a fact that your equipment will work.As a rule, something caused the combustion of this element and it could “pull” a couple of other elements along with it, not to mention the fact that it is quite difficult for a non-professional to find a burned-out m / s. Plus, in modern equipment, SMD radio elements are almost universally used, soldering which with an ESPN-40 soldering iron or a Chinese 60-Watt soldering iron you risk overheating the board, peeling tracks, etc. The subsequent restoration of which will be very, very problematic.

The purpose of this post is not any PR of repair shops, but I want to convey to you that sometimes self-repair can be more expensive than taking it to a professional workshop. Although, of course, this is your money and what is better or more risky is up to you.

If you nevertheless decide that you are able to independently repair the radio equipment, then when creating a post, be sure to indicate the full name of the device, modification, year of manufacture, country of origin and other detailed information. If there is a diagram, then attach it to the post or give a link to the source. Write down how long the symptoms have been manifesting, whether there were surges in the supply voltage network, whether there was a repair before that, what was done, what was checked, voltage measurements, oscillograms, etc. From a photo of a motherboard, as a rule, there is little sense, from a photo of a motherboard taken on a mobile phone there is no sense at all. Telepaths live in other forums.
Before creating a post, be sure to use the search on the forum and on the Internet. Read the relevant topics in the subsections, perhaps your problem is typical and has already been discussed. Be sure to read the article Repair strategy

The format of your post should be as follows:

Topics with the title “Help fix the Sony TV” with the content “broken” and a couple of blurred photos of the unscrewed back cover, taken with the 7th iPhone, at night, with a resolution of 8000x6000 pixels are immediately deleted. The more information about the breakdown you put in a post, the more chances you will get a competent answer. Understand that the forum is a system of gratuitous mutual assistance in solving problems and if you are dismissive of writing your post and do not follow the above tips, then the answers to it will be appropriate, if anyone wants to answer at all. Also note that no one should answer instantly or within a day, say, no need to write after 2 hours “That no one can help”, etc. In this case, the topic will be deleted immediately.
You should make every effort to find a breakdown on your own before you get stuck and decide to go to the forum. If you outline the whole process of finding a breakdown in your topic, then the chance of getting help from a highly qualified specialist will be very great.

If you decide to take your broken equipment to the nearest workshop, but do not know where, then perhaps our online cartographic service will help you: workshops on the map (on the left, press all buttons except “Workshops”). You can leave and view user reviews for workshops.

For repairmen and workshops: you can add your services to the map. Find your object on the map from the satellite and click on it with the left mouse button. In the field “Object type:” do not forget to change to “Equipment repair”. Adding is absolutely free! All objects are checked and moderated. A discussion of the service is here.

I have such a dryer covered. The board is slightly different in appearance. But the essence is the same.
Symptoms: left for the night - in the morning the engine continued to spin, but somehow weakly.
The heater does not heat. The LEDs are off. When you press the power button, the fan spins faster for a couple of seconds,
then barely back.
There is no voltage at C3.
I checked for breakdown with an analog tester C1, C2, C3 - everything is normal.
I checked the Zener diode D1 as a diode with the same tester - also the norm.
By the way, the Zener diode seems to be 5.6 volts 500mA. It has the letters 5V6.
Like this: 1N4734A

Diode D2 is also normal. D3 does not ring in either direction.

The microcircuit is there by the way ST7FLITE09Y0B6. And this is a microcontroller

Those. just buying it probably will not do, do you need a firmware running on it and a programmer?

This article discusses a solution to the problem of repairing drying for fruits and vegetables at home. The sequence of actions during the repair will be considered on the example of the drying of the SATURN trademark and the ST-FP8504 model.

This article is written for those people who are unable to contact an authorized service center due to its absence or excessive distance from their place of residence. If in your locality there is an authorized service center serving the trademark of your equipment and you have not expired the warranty period, our advice is to contact them.

We will fix a defect that occurs most often in every home - the dryer does not turn on. There may be several reasons for this defect.

Let's list the possible reasons:

1) violation of operating conditions (overloading with products, mechanical damage);

2) damage to the power cord;

3) defect of the on / off button;

4) defect of the bimetallic adjustable thermostat (temperature controller);

5) overheating of the heating element (tena) and, as a consequence, the operation of the protective thermal fuse (sagging or shorting of the heating element coils);

6) motor defect (low rotation speed, contamination of the sliding bushings on the impeller motor shaft, which supplies air to blow off the heater).

You can read a description of the most common defects in the article: “Diagnostics of the device. Where to start repairs? "

Further actions are as follows.

Bring the knob of the temperature regulator on the drying body to the minimum value. In this case, you will hear a characteristic click of the open contacts. You can try to turn on the drying for a short time using the power button on the control panel. Be careful including dryers with an open cabinet. We visually control how the impeller motor picks up speed. If the speed is too slow and the air flow is clearly insufficient for the drying to work properly, it may be necessary to replace the impeller motor. You can check the motor by gently pushing the impeller in a circle. In a serviceable motor, the impeller must complete more than one revolution. The resistance of the motor winding should be more (here the value is in Ohms). To replace the motor, another serviceable motor is required. We unscrew the heater body and several screws around the perimeter of the metal plate. We turn over the plate with the motor and remove the impeller from the motor shaft. The motor is secured with four screws. In order to unscrew these screws, you need to make a lot of effort and a screwdriver with unworn working surfaces. If, after replacing the motor during a test run, the drying performance has recovered, we assemble the unit in the reverse order.

Drying can now be tested in all operating modes.

According to the experience of repairing such devices, there are the following spare parts for vegetable growers: bimetallic adjustable thermostats JT-208B, KST-101B, KST-201B, KYS-329-A, TA-018; non-resettable thermal fuses (fusible) 128, 130, 133, 135 degrees, etc.; power buttons KCD1, XCK-012; motors HA-6010M23, XD-6013C; control board KYS-329-B.

All examples and recommendations presented in this article are of a recommendation nature and are not conclusive and the only correct one. The author does not urge you to do something that can be done by the specialists of the service center. And they will most likely complete the repairs faster and better. I wish you continued success in this difficult renovation business.

Valle is an online store of spare parts and accessories for vegetable dryers from world manufacturers.

Fruits are a source of pectins and vitamins, the consumption of which provides the body with essential nutrients. But fresh fruits are available only during the warm season. You can prepare them for the winter by means of a certain treatment, which involves two options. Vegetables and fruits can be preserved or dried.

A fruit dryer is an excellent device that you can build yourself with minimal financial costs.

Today the second method is preferable. A fruit dryer is an excellent device that you can build yourself with minimal financial costs.

The principle of operation of the dryer is the effect of an increased air flow on the crushed fruit. As a result, metabolic processes in fruits are activated, moisture leaves, and they dry out faster. There are three types of dryers, each with its own device.

The construction of a standard dryer consists of 4 main parts:

fan;
hulls;
tray for fruits and vegetables;
electric motor.

The functioning of the solar dryer is based on the penetration of rays through the transparent material and heating the sheet mounted on the back wall. This increases the temperature inside the appliance when the reading can reach 50 ° C. Fruits and vegetables, being in such conditions, dry out. Thanks to good ventilation, moisture is removed to the outside, which prevents the formation of mold on the fruit. A cold air stream enters from the lower side of the structure, it heats up in the body and exits through the upper opening.

wooden case;
pallets for chopped fruits;
transparent polycarbonate cover.

The infrared dryer is a multifunctional handy device. It can be rolled up. This will greatly facilitate storage of the device. It can also be easily transported if necessary. The potential of such a device is 58 ° C, which allows you to get high-quality dried fruits. This device will successfully cope with the heater function.

The structural elements of such a dryer are as follows:

infrared film;
case from the box;
transformer;
wiring.

Doubts may arise about the advisability of making a dryer. After all, if the fruits are placed in an ordinary attic, after a certain period of time they will reach the required state. This option does not require effort and financial investment. But it also has a drawback. In this case, vegetables and fruits will attract insects. It is impossible to prevent the occurrence of this situation, since constant contact with air is necessary for the complete drying of the fruits. Accordingly, they cannot be placed in a sealed package.

Undoubtedly, you can treat fruits with a special composition so that insects lose interest in them. But the taste properties of the fruit change. In addition, after such processing, the fruits retain chemical components in their structure, and it is no longer possible to call them completely safe.

Important! A dryer is the most acceptable way of storing supplies in order to enrich your diet with vitamins for the winter.

For the construction you will need a professional tool

There are several options for manufacturing a structure.To get a conventional dryer, you need to prepare:

materials for the body. It can be 60 cm x 80 cm plywood sheets or an old refrigerator;
metal mesh;
trays;
a fan with a motor or 2 incandescent lamps with a power of 150 W;
self-tapping screws.

For an infrared dryer you will need:

electrical wire with switch and plug;
foil 100 cm x 50 cm, intended for warm floors;
bituminous and PVC insulation;
2 terminals, 2 eyelets, 2 clips;
soldering iron;
metal bar.

The solar dryer is manufactured using materials and tools such as:

wooden beams;
a metal sheet;
mosquito net;
black paint;
polycarbonate or glass;
lining or plywood;
brush;
self-tapping screws;
level.

Each variation of the design of the drying cabinet has its own characteristics, so making a choice in favor of one design or another is solely your right. Let us consider in turn the procedure for constructing each type of drying device.

For the construction of a conventional structure, it is first necessary to prepare the hull. Next, you need to do the following manipulations:

To complete this work, you will need rubber gloves and tight clothing.

Select the item from which the dryer will be made

The body part of the dryer consists of one wall. There is no need to install the cover and bottom, since the air flow must freely enter and exit the structure. Therefore, holes must be made in the upper and lower parts of the case.

Making ventilation holes

Instead of the bottom, a fine mesh metal mesh is used. It can be replaced with the grill grate by removing the handles. Or make the bottom out of an old door.

Inside, we trim the walls with insulating material.

We fix the guide rails on which the pallets will be fixed. They can be constructed with wooden battens and a mosquito net.

We insulate the dryer and attach the slats

Next, a fan is installed - it can be removed, say, from a thermal electrical device.

We fix the fans to the case

Important! If you can't find this part, incandescent bulbs will do. Trays are placed in the upper part of the body. A hook is installed on the door.

We connect the device and test the performance.

Infrared dryer assembly diagram

The process of building such a dryer is quite simple and does not take much time. Lavsan film is used as a heating element. You will also need two plastic crates. All actions are reduced to the following aspects:

We cut the supporting corners and walls so that the products do not come into contact with the heating element.
Cut out 3 bases for holders of infrared parts from cardboard.
Radiation from the heaters comes in two directions. To direct it towards the fruit, you should use food foil, which will act as a reflector.
We glue the cardboard.
The heating elements must be connected to a transformer. The wires are connected using flat connectors, electrical tape and pliers. This method will allow you to do without soldering.
The ends of the wires are connected and crimped with a connector. Tape will help keep moisture out.
When connected on the transformer, 4 connectors are made for each polarity. For convenience, wires of different colors should be used.
Then the whole system is assembled.
The transformer is connected to the network.
This concludes the work.

This version of the device makes it possible to use solar energy to dry the fruit. As a result of this natural process, the fruit retains all its beneficial properties. So, the construction of the structure occurs in this order:

The bars are knocked down between themselves and three parts are obtained, from which the frame is further formed.

Assembling the frame for the solar dryer

Then the shelves are installed. They should be placed towards the sun at right angles.To do this work correctly, the structure is initially placed on the street and the movement of the shadow is observed.

Installing shelves in a solar dryer

The following step will help you determine where the shelves will be placed. The body is tilted and tracked the moment when the contours of the shadows connect. Further, using a level, mark the necessary places on the sides of the future dryer.

The sides and back are sewn up with lining panels or plywood. Holes are left at the top and bottom and covered with a mosquito net to protect the fruits from insect attack.

A metal sheet is attached to the back, which will provide heating.

All internal sides of the structure are painted with black paint, as this will contribute to the formation of a greenhouse effect.

At the final stage, the device is covered with polycarbonate, transparent slate or glass.

Covering the dryer with polycarbonate

The dryer is now ready for use.

The rules for using a solar dryer are reduced to the following aspects:

To get dried fruits, they should be cut into small pieces, put on trays and placed in a case.
It is impossible to immediately influence them with a stream of air. Fruits and vegetables should lie in the device for 3-4 days, only after this time you can start the drying process.
One of the necessary conditions for high-quality drying of fruits is the presence of a certain temperature regime in the structure. It cannot be raised prematurely. For this, the walls of the dryer are covered with heat-insulating material. The temperature level should be between 40 ° C-50 ° C and not exceed this figure. Otherwise, the content of vitamins in fruits will be significantly reduced.
The solar structure is installed at a slight slope so that the rays fall on the structure. To do this, lean the dryer against any suitable surface. Metal pipes can be attached to the side parts of the case, which will act as a support.
For the manufacture of shelves, it is recommended to use a mesh material so that air can circulate freely through the dryer. A mosquito net will work.

It is common knowledge that fruits that have been exposed to heat will lose a significant portion of their nutrients. The method of drying fruits and vegetables will allow you to get the most useful products. Thus, they retain their nutritional value at room temperature and take up relatively little space. We have told you how to make a device that will help to prepare fruits. Use our instructions and enjoy vitamins even in the cold season.

Friends today in our review, a Polish-made ZELMER electric dryer is very cool. In it you can dry both vegetables and fruits and even fish, the instruction comes with it. Model ZELMER

Hello everyone! The harvesting season for the winter is in full swing and today is my review of electric dryers for vegetables, fruits and berries.

You already know that I am a supporter of proper and quality nutrition. Naturally, I care about high-quality nutrition, first of all, for my child.

In winter, I often cook dried fruit compotes. And what could be tastier than your own dried fruits grown in your garden ?! And two years ago I decided that all dried fruits can be made by myself - there would be a desire and an opportunity.
This is how a household dryer appeared in our house. We did not read the reviews at that moment, did not choose a specific model, but simply came and bought what was in the store. There was no choice there - all August is the month of blanks and, apparently, they bought everything before us. I had to be content with what we have, fortunately, the price is not for the cloud.
We purchased a dryer from the Polish company Zelmer, model FD1001.

Moreover, the manufacturer assures that the drying has a high power of 520W, 4 capacious sieves (pallet), electronic control and convenient storage of the equipment itself. There was no doubt about the acquisition.

And here is the drying itself. The pallets are stacked tightly for easy storage.

Drying trays are folded out for the drying process. Drying becomes high enough.

Drying is easy, I can hold it with one hand without effort.

- the power cord is short. But you can get out of this situation with the help of carrying, or put the dryer closer to the outlet. It seems like a trifle, but this problem brings some inconvenience. During storage drying, the cord is wound around the ventilation and heating element.

- EURO plug.
- 4 transparent pallets.

The pallet has a radius of 30 centimeters.

- elementary control panel. Drying is controlled by two buttons. On / off button and mode switch button.

- drying works in two modes: the first heating stage - 250W and the second heating stage - 500W.

- there are 4 rubberized feet.

The bottom of the dryer is uneven, which allows air to circulate and prevents the appliance from overheating.

And, of course, there are obligatory instructions included with the drying.

Let's move on to the process of harvesting fruit for the winter. For this we need the fruits themselves. In my case, these are apples. The apples have to be cut thinly enough so that the fruits dry evenly without any moisture remaining inside the fruit.

We put apples on pallets. Please note that you must not lay out the fruit too tightly. Otherwise, the air will have nowhere to “walk” and the drying may overheat. Be sure to close the dryer with a lid.
The lid has holes for air circulation, so there is nothing to worry about overheating of the device.

Let's see what happened to the fruit after an hour of drying in the second mode, that is, 500W. Let's look at each pallet starting from the top.

The photo shows that the bottom 4 pallet is more or less dried, while the top 1 pallet is only slightly weathered.
For a more even drying of fruits, it is necessary to periodically change the trays in places. And since I started drying fruits late at night, I will leave it on the first 250W mode for the whole night without changing the pallets. Overall, I got 10 hours of drying in the first mode without alternating pallets. Let's see what came of it.

The bottom pallet is the 4th driest, the upper ones are slightly damp. Let's see a slice of apple cut.

Such apples can already be left, but do not close them in a plastic bag, otherwise they may become moldy or some kind of infection may start in them. They are not wet, almost croutons. Usually I put such apples in a cloth bag and they are perfectly stored all winter.
Here's how many dried fruits I got from one drying batch.

Of course, this is not enough for winter, so we will dry it many, many times.
Yes, when purchasing a drying machine, it seemed to me that the process would be quite fast - a couple of hours and the batch was ready. But the process of drying apples took me 10 hours, however, in the first drying mode (250W). Of course, in the second mode, the drying process will take much less time - 5 hours, but still it is not two hours. It annoys me a little. These are apples and 5 hours, and when I dried the plums, the drying took me three nights on the first mode. This is already a fairly long process and you need to be patient to get the result.
The drying fan works quite loudly. The manufacturer promises a noise of 66 dBA. I do not have a noise meter, but when I dry fruit at night, I close the kitchen door.

So, let's summarize.
PROS:
+ DIY dried fruits from your garden;
+ two drying modes 250W, 500W;
+ compact drying, convenient storage of the device;
+ price.

MINUSES:
- a small amount of fruit at the exit;
- long-term drying of "wet" fruits;
- noise;
- short power cord.

Yes, it will not be possible to dry the fruit on a production scale, but for that it is household - in small batches every day and you can provide yourself with wintering.
Well, the noise. The noise cannot be avoided, because the fan is running. You have to be ready for this.And if you don’t dry at night, then it will not bother you - you practically won’t hear drying in the daytime noise.

We bought a dryer two years ago in the midst of winter harvesting.

Despite all the disadvantages of drying, I'm happy with it. For the third season, we will drink compotes from our dried fruits - nothing unprocessed, one might say, environmentally friendly and healthy.

Whoever has their own summer cottages, vegetable gardens, households, I advise them to purchase. A necessary thing in our life in the days of GMOs, soybeans, starch and all kinds of byaki.

Thanks to everyone who took the time to give my feedback!

In winter, it is so great to cook a compote from berries and fruits grown and dried for the winter with your own hands. Or make a soup of mushrooms, which he collected and dried himself. And you won't have to buy greens at all in winter, because we will have a supply of dried dill, parsley and any other greenery. Dried vegetables and fruits retain maximum vitamins and minerals. But drying food in the oven or in the fresh air is troublesome. Chopped food attracts a variety of insects.

Today we offer you a story about testing the ZELMER FD 1002 dryer.

The kit includes instructions that describe in detail what products can be used and how to prepare them.

The time it takes to dry the product depends on the type of product, its moisture content, and how thinly the product is cut. It takes an average of 4 hours to dry one batch of products.

The heating element in the device is located at the bottom, but at the same time the products are dried both from the top and from the bottom in the same way, and there is absolutely no need to change the places of the drying containers. The appliance has 4 trays, but they are quite roomy. The distance between the trays is adjustable, which is convenient for drying large products, as well as for storing them. The dryer has hot and cold air regulation function. It is possible to shorten the time or set the time for additional drying.

The device has a wide range of uses. In addition to drying vegetables, berries, fruits, mushrooms, herbs, you can prepare snacks from meat and fish in the dryer.

The dryer has a very convenient and simple control panel. Has a display. There is a built-in timer. After the cooking time has elapsed, the dryer will switch itself off. The lid of the device is equipped with a comfortable handle. Transparent trays allow you to monitor the cooking process without opening the dryer, to control the degree of readiness of the products. A fine mesh is installed at the bottom of the pallets, which will prevent the smallest products from falling through the grate.

The dryer works very quietly, which will not interfere with your rest.

When the heating element gets too hot, it automatically turns off and the device operates in fan mode. After cooling down, the element turns on again and the drying process continues as usual.

The device has rubberized feet, which will prevent the dryer from sliding, no matter what surface you put it on. There is a compartment for storing a network cable, its length is 120 cm.

We did not identify any shortcomings in the testing process.

In general, we were very, very pleased with the tested device. The dryer has shown itself from the very best side, both in terms of convenience and functionality, ease of operation, and, of course, safety. I would like to note the good prices for quality. Such a dryer is an absolutely irreplaceable thing for gardeners, mushroom pickers, gardeners. If you choose this dryer, you will be the perfect helper in your kitchen!

Consider the device design. Let's imagine how to make a vegetable dryer ourselves. Let's share our experience. The mechanism is simple - we make a copy. The electrical part is bought in the capital market, cut from other devices without sacrificing efficiency.

Wood vegetable dryer

Remember the story about the double boiler. The vegetable dryer is similar, only the other way around:

There are several tiers of mesh boxes on top of each other.
The top cover has a hole in the middle for the outlet of moist air.
In the pallet there is a spiral in the center, in the channel.
With the help of a simple electric motor, air is forced and enters the working chamber through a round opening in the floor.

Now let's see how to make on our own, without buying in a store, a vegetable dryer.

There are not always so many vegetables and fruits that an incredible amount of space is required for placement. The dryer can be easily replaced by any modification of the airfryer.

You will need a baking sheet from the stove. Lay out the food: vegetables, fruits, mushrooms, berries.
Remove the cover with the lamp and fan from the airfryer. We take the high mesh from the set to the baking sheet.

Dryer device for vegetables

Set a makeshift vegetable dryer timer for an hour. At the signal, you will come to mix the products. After a quarter of an hour, you will need to repeat. Continue to dry completely. No need to do it with your hands, no extra space in the kitchen is needed. No airfryer - buy a cheap one to try.

If you can't find an airfryer, try a hairdryer, a kitchen hood motor. Put on the minimum mode to begin with. We do not recommend using the grill: the outlet of the hair dryer is narrow, melt the spout. It is easier to hang the device on a strong rope, directing it to the right place.

Minus: the hair dryer does not have a timer, the device may not withstand long work. It is good if the inside is a thermostat based on, for example, a bimetallic plate. Take it out of the oil heater, electric kettle, iron. On the shelves of online stores there are thermostats for adjusting the temperature of the heating system - the device is good.

Otherwise, the fuse will blow out from prolonged operation (cause: overheating of the motor windings). A hair dryer will be the less preferred device. It is better, with large blanks looming on the horizon, to try to make a dryer for vegetables yourself, repeating, copying the details of the factory design.

Difficulty in the correct selection of the power of the spiral. In the video reviews we see: the body of the dryer, plastic nets for vegetables. Indicates a low temperature. We recommend that you study the characteristics of a purchased vegetable dryer, then copy the design. We suggest you go to Yandex Market to get acquainted with the range of offers. Go to the site, type in the line "electric dryer for vegetables, fruits, mushrooms."

In the fall of 2014, a vegetable dryer with a cylindrical plastic casing (Sukhovey M5) cost 3,000 rubles. Let's take a closer look:

power 600 W;
5 tiers of 1 kg capacity each;
there is no timer and other automation;
drying temperature up to 70 degrees.

We propose to improve the case. For construction you will need:

A more powerful motor, cooler (fan) - for example, remove it from the system unit.
Nichrome spiral with a resistance of 90 ohms. Ask for the length in the market. If you do not know, take a tester, measure the resistance of the cut, the length of which is known. Use the calculator to find the value you want. Why 90 ohms? To make the power 600 W, more precisely: 220 x 220/90 = 537 W. If you take a slightly shorter cut, the spiral will heat better, the danger of fire increases at the same time. As an option: take a hair dryer spiral, only turn on the elements in series to get a resistance of 90 ohms. Plus: quartz cross plates are already available.
Heat-resistant plates, like a hair dryer. You can take instead of the indicated ones - a halogen lamp of an acceptable diameter.
We recommend making a case of steel, buy a grid for tiers made of food-grade steel. No need to take a mosquito. It is not necessary to use welded electrodes for racks, copper wire with lacquer insulation, and other indigestible things.Only food grade steel, or aluminum (food grade).
Take the body from canned food. Previously, tomato paste and olives were sold in large tin cans. As a last resort, roll the desired size from the sheet. Do not solder, riveting is permissible.

Any craftsman can independently assemble. Safety precautions: Provide a temperature control mechanism in a secluded place. A bimetallic plate from an oil heater will do.

If you can get a thermostat with a handle - great. Let's see how to use it.

A reflector is placed above the outlet in the bottom. The area of the part overlaps the channel, guarantees: berries will not fall on the spiral, will not create a fire hazard. Protect the sides with a net. Fix the bimetallic plate with adjustment means to the reflector. Feed the spiral of the vegetable dryer through an impromptu relay. The snag is inertia. The reflector is made of sheet metal - wait for the constant clicking of the bimetallic plate. Make from steel 5 - 6 mm - inertia will be provided.

For the distance between the tiers - make according to your needs. In most cases, five centimeters is sufficient for a vegetable dryer. The CPU cooler requires DC power. Take a charger for mobile equipment: phone, iPad, walkie-talkie. Voltage less than 12 V - will cause a regular decrease in speed. Place the fan under the spiral. There is no desire to get involved with direct current - find an asynchronous motor (collector is very noisy). Silent motors in fans, refrigerators, hoods - be guided by hearing.

A homemade vegetable dryer needs to be safe. Ground the metal housing. Moisture can get inside - it will cut out the plugs.

It is easier to dry vegetables in the oven - it is customary in Russia. A Russian stove is used. Baking trays are not placed inside - on top, on a lounger. Mushrooms and berries dry out over a long period of time. A gas stove is a poor dryer. Blue fuel contains minimal impurities. Foods should not come into too much contact with combustion products. Easier to use the battery. In the Russian Federation, it is customary to store dried fruits in winter there against dampness.

Summer residents take advantage of the sun. The seeds are dried and fried in a pan. The principle of operation of a vegetable dryer is different. Discussed unconventional methods of using the air conditioner. The outdoor unit was a vegetable dryer: the condenser temperature reaches 70 degrees Celsius. You don't need to look for a fan - it's worth it, energy is not wasted (fewer calories are carried away by the wind).
