As described above, you can disassemble the centrifuge juicers from any manufacturer. There may be nuances in the design, but they do not fundamentally affect the dismantling procedure. Similarly, this procedure is performed with vertical screw counterparts. The difference is that instead of a grater, there is a volumetric auger in a protective casing. The horizontal auger devices resemble a meat grinder in terms of the device. They are dismantled:
The described mounting / dismounting options are not a guide to action and are for informational purposes only. Each specific model of the device is disassembled in accordance with the manual supplied with the device, which will avoid accidental breakdowns.
A juicer is a must-have equipment for all lovers of fresh juices. Autumn is harvest time. Fresh apples in the gardens of summer residents are pleasing to the eye. At first, it’s not clear how to deal with such volumes. Juicers come to the rescue. But, like any technique, sooner or later they break down. To make your life easier, you can repair a broken apparatus. Today there are many types of juicers, such as: Bosch (Bosch), Moulinex (Moulinex), Scarllet (Scarlet), Philips (Philips), SVA, Zhuravinka, Cameron (Cameron), First Austria (First Austria). The good news is that on the Internet you can find various videos on the topic of repairing juicers with your own hands.
Each juicer comes with instructions and an assembly diagram. But if you have been using the device for several years, the instructions could be lost. Even in this case, it will not be difficult to disassemble the device.
Having carried out repairs with your own hands, difficulties can arise only during the first disassembly.
The main thing is not to overdo it with efforts when disassembling. Otherwise, there is a risk of damage to the juicer body.
After disassembling the juicer body, then you need to remove the pulley. Usually, it is twisted off the shaft in the opposite direction from the working rotation.
There is an exception for auger juicers, which are similar in design to a meat grinder.
A breakdown of the juicer can be caused by both natural wear of materials and engine damage.
Remember that before disassembling the appliance, you should not just set the switch (lever) on the case to the Off position, but also completely disconnect the power cord from the power outlet.
If you do not have enough experience in repairing, it is better to seek help from a specialist.
These are the main problems with juicers. And only one of them is serious. The first two can be solved quickly enough.
It would seem that everything has already been considered. How to disassemble the juicer is clear. What is the peculiarity of the Zhuravinka juicer? The peculiarity is that when you get to the engine compartment, you will not see any more mounts that would allow you to access the engine compartment.
Don't worry about this. All compartments are very tightly covered with a plastic disc, to which a grater-shredder was attached. It takes a lot of effort to remove it.
Independent repair of all types of juicers, including "Zhuravinka", is reduced to replacing broken parts, such as: wires, switch, bearings or electrical plug
It is important to keep track of the effort you make so you don't break anything.
After removing the disc, four screws will be available to you, removing which you can get the engine and eliminate the cause of the breakdown. The Zhuravinka juicer is assembled tightly and quite simply. Unlike the First Austria juicer, which, according to numerous reviews, causes difficulties in disassembly, in disassembling the Zhuravinka juicer, additional efforts require only a disk that closes access to the engine.
Currently, Bosch juicers (bosch) with a capacity of 380w and 700w are gaining popularity on the market.
Bosch products continue to be associated with build quality, functionality and reliability
Wait until the motor has come to a complete stop before opening the juicer. To open the lid of the juicer, you must first move the switch to the "open" position.
The pomace container must be emptied before the pomace rises to the top of the container, which should be grasped with your hands to remove it.
It is recommended to clean the cake container and strainer at the same time.

Whether it's spring, summer, autumn or winter, the body will always need juice. And it doesn't matter what kind of juicer you have: Bosch or Scarlett, Philips or Moulinex, the main thing is to understand the basic principles of assembly / disassembly of this device. So that, if necessary, replace the failed element. Let your juicer serve you long and productive. Make yourself and your loved ones happy every day.
The basis of the juicer is the engine. Today, asynchronous, collector electric motors are used. No wonder - the technician knows no other. Actually, repairing juicers with your own hands of frequencies is faced with the situation of a failed engine. It is almost impossible to replace the mechanical part, devices operating on the basis of meat grinders break couplings, plastic bushings when a bone hits, hydraulic presses have a lot of fiddling with the oil system. Let's consider the questions, do not wait for a detailed guide, but we will consider the main types of faults in sufficient volume.
We hope that reading the review will help our readers to fix the juicer of their choice on their own. Nothing complicated inside. Don't be intimidated by the upcoming renovation of Scarlet's juicer.
Repair of the Rossoshanka, Santos juicer - the difference in the price of the product is 30 times - there is a motor inside. Rossoshanka does not work for long, noisy, the essence is the same. The properties of the juicer are determined by the design of the mechanical part.
The advantages of induction motors are considered to be simplicity of design, maintenance, high efficiency. Less noisy than collector ones, however, when powered with a voltage of 50 Hz, it is difficult to get rpm above 3000 rpm. Juicers consider this a serious limitation, Santos has a fairly large centrifuge diameter. Let's describe Rossoshanka, Neptune, and other domestic high-performance juicers in a similar way.
Manifolds are devoid of restrictions, they turn out to be smaller in size. Lose in other important professional juicers:
Noise level.
Short period of continuous operation.
On the shaft of electric motors, we see impellers blowing over the stator coils. It is made to cool the windings during operation. If, when disassembling the juicer, it was found: there are no elements inside, it is possible to supplement the design by wisely choosing the shape of the blades. Will soften the thermal modes of operation of the electric motor. From the above it follows: asynchronous motors are preferable for the manufacture of high-quality juicers, it remains to solve the problem of speed.
In the case of centrifugal models, the issue is leveled by an increase in the diameter of the working chamber. As a result, with increasing distance from the axis, the centrifugal force increases. It is permissible to reduce the speed of the juicer motor without loss of quality.
Each device is supplied with a set of speeds. In asynchronous motors, it is realized by proper separation of the stator coils. Not all work at the same time, the result is a variation in speed. The scheme is often implemented, it consists in the correct commutation of the electrical circuit with buttons. The technical solution has great reliability, durability, and fault tolerance. A positive point. As for the speed, you can increase it using an inverter in the circuit. It is clear that it will lead to an increase in the price of the device at times.Smooth speed control can be achieved.
As for asynchronous motors, it's easy to do. Amenable to adjustment, avoiding complex circuits. Losses are reduced if the windings are supplied with direct current. Inductive resistances have little effect. The minus is small: a complex power supply is required, which reduces the efficiency of the juicer. The listed key points must be clearly understood if there is a desire to replace the engine. Readers can insure against winding burnout by bothering to include a thermal fuse at 135 degrees Celsius in the circuit. The element must fit snugly against the winding. Ideally, the thermal fuse is recessed between the turns of the wire. Provides heat exchange.
Forced cooling will not interfere. How it is done in the case of juicers, any devices, have already been told. You can borrow an induction motor starter relay from the refrigerator, along with the motor. There are two subtleties here:
In juicers, a starting winding is rarely used; a scheme with dividing the stator coils is used.
The motor type must match the relay, the overheating protection will not work.
There is a weak point in cheap juicer models: they are not protected against engine burnout. Why not put a relay like a companion for refrigerators. A difficult question, we leave it to the readers to decide on their own. The cost of other freezers is an order of magnitude (!) Lower than top-end juicers. The refrigerator works day and night, avoiding begging for the required break, does not turn off in summer. The power of the device is considerable.
For our reasons, reliable technology is closer to nature, figuratively speaking. This is directly confirmed by the design of the Norwalk juicer. So in a refrigerator, often all sensors have nothing to do with electrics, let alone electronics. We need more bimetallic plates, thermocouples and other reliable and simple equipment. By the way, gas water heaters do just that, even ignition on a piezoelectric element. In this case, the technique works for a long time, is reliable and efficient. Overheating of the windings is easy to assess by the temperature of the magnetic circuit. Why isn't it done in juicers? Unable to answer this question.
What about Norwalk? Do-it-yourself juicer repair in this case is closely related to hydraulics, which was already mentioned at the beginning. Design:
There is a high-speed engine inside.
The auger is put on the shaft according to the principle of action of a meat grinder.
The ground cake is put into a bag and placed on the table of the hydraulic press.
The oil cylinder is driven by a belt drive, as in washing machines.
Thanks to a clever solution, the compressor is devoid of electrical parts. Steel block with spacers. The motor, on the other hand, is made in the best traditions of the machine. One glance is enough to understand: in 5 minutes it will not ask for rest, imitating Zelmer. In light of the foregoing, we believe that it is enough to find a Norwalk screw juicer attachment instead of a meat grinder, having received an excellent device for a long-term operation. According to domestic GOST, it means that the equipment can withstand merciless operation during a work shift (8 hours).
The hydraulic unit will need to be filled with new oil periodically. The old is merged first. After removing the cylinder cover, it is supposed to remove the internal mechanism with a return spring, scoop out the oil. Keeping the position, the compressor drive starts. Gradually the oil will be in the cylinder. The new is poured three-quarters of an inch below the lid. Will the air gap interfere with the work? Masters say: powerless to harm. You will need to monitor for leaks of fittings, compressor, cylinder. Add, the return of the table to its original position is carried out by a spring after pressing the handle of the release valve.

If it comes to attachments for meat grinders, you will have to change plastic gears and couplings. They come in a quantity of 2-8 in a set, sometimes you have to buy new ones.Steel gears of meat grinders-juicers are rare, there is a chance of failure of a precious engine. You wonder how industrial units work ...
It is clear to readers that the main types of faults relate to the engine. First check the power supply, then the continuity of the windings begins. Having localized the malfunction, they try to rewind the coils. In the case of a collector motor, doable, the stator is a dull choke strung on a magnetic circuit. The manifold motors are called for each position of the section until the drum completes a full revolution. The rotor of the squirrel-cage induction motor is incapable of burning. The current is small, copper wire is often inseparable from the base of the "squirrel cage" by insulation. The device of the juicer is so primitive, the mechanics (bearings, oil seals, gears) and the drive break down.
They talked about the repair of power supplies more than once. Impulse sources are found in expensive models equipped with the rudiments of intelligence.
We compare domestic juicers Rossoshanka, Neptune and Salyut.
In this article, I will introduce you to domestic products by conducting a comparative review of garden squeezers from Rossoshanka, Neptune and Salyut. All the models presented have positive reviews, and you can buy them in almost any hardware store, at a fairly pleasant price.
Juicer Rossoshanka SVPR 201 m
This electric (non-auger) model for vegetables and fruits is characterized by increased productivity and centrifuge utilization. The manufacturer recommends using only hard fruits for juice squeezing, since soft fruits and vegetables after processing turn into a paste, of which there will be very little juice. But for apples, this device is just perfect. The device is distinguished by high build quality, tight fit of all parts, high-quality plastic and stylish design, which domestic juicers can not always boast of. Juices are produced quickly and in large quantities. The design features make it possible to protect the seeds of the fruit from damage, as a result of which acids do not enter the juice. For private households and summer cottages, this model is simply irreplaceable. The productivity level is about 70 kilograms of processed fruit per hour, which is explained not only by the powerful motor, but also by the large feed opening. The cake is dry. A pleasant bonus is a moderate noise level, which does not get on your nerves even after an hour of continuous work. The only negative is significant vibrations during spinning, as a result of which it is recommended to remove all objects from the table.
Juicer Neptune
The 8 kg squeezer has several advantages at once, allowing them to be distinguished from competitors. Firstly, it is less weight. The appliance can be easily picked up and moved around the kitchen as needed. Secondly, the device is characterized by increased power, as a result of which the productivity reaches 120 kilograms of processed fruits and vegetables per hour. In spin mode, the model can show an efficiency of 45 percent. There is the possibility of quick mass processing, with the possibility of squeezing juice from tomatoes or cherries.
It is especially worth highlighting the unique design of the grater, which allows you to work with round vegetables and fruits without preliminary grinding. As in the previous model, the bones remain intact, as a result of which you get pure juice, with the possibility of its further conservation. High working speed is achieved by creating more pressure on the fruit, as well as effective removal of the cake. The spin is almost continuous.Among other things, among the advantages, one can single out an affordable price, as well as the safety of the device, which is achieved through certification and the implementation of special security systems.
Juicer Salute
A device from the domestic manufacturer Salut (Penza), capable of producing maximum performance with a minimum of financial and labor costs. The powerful electric motor handles all hard fruits without any problems, including apples, beets and carrots. Distinctive features of the model - emphasis on reliability, durability and ease of handling. It is unlikely that you will need to read the instructions for use, and if repairs are suddenly required, you can repair the device yourself according to the wiring diagram, or find the necessary spare parts in Voronezh or any other city in our country. The simplicity of the design of the electrical device is simply amazing. The plastic case lightens the weight of the model with the cake container, so you can easily move it from place to place. The efficiency of squeezing juice from fruits is at least 50 percent. The operating mode is continuous. The only thing is that sometimes you need to stop the device to clean the drum from the cake, which turns out to be absolutely dry. The declared service life is about 6 years of continuous use. But since we are talking about a domestic model, you can always throw 5-10 years by this time. The purity of the juice obtained is about 92 percent.
Do-it-yourself juicer repair is not something fantastic. The device is quite simple and practically indistinguishable in different models. Whether it is a domestic juicer Dachnitsa or an imported one Bosch , they all work on the same principle, and are arranged in approximately the same way ... With some knowledge in mechanics and electrics in stock, you can safely pick up a tool.
Juicer breakage is a common occurrence. This is not surprising, because such dacha paraphernalia experiences enormous stress during the harvest season. At the heart of every fruit and vegetable juice device is ordinary press ... It doesn't matter in what form it is presented. The manual citrus juicer works by pressing and turning the fruit. The mechanical juicer is supplemented with units that allow to reduce physical efforts of a person and ensure greater productivity.
In any case, a decent load falls on the devices, and the increase in parts raises the percentage of breakdowns of the devices used. Even a manual juicer, presented as a press, where the pressure on the piston is produced by the rotation of the screw - and it is not always able to work reliably for a long time.
Repairing manual juicers is not that difficult. If we talk about electrical models, then the range of breakdowns is significantly expanded here. The search for a breakdown must be done in two directions: mechanics and electrical.
If your electric juicer shows no signs of life, makes a lot of noise or vibrates, do not start disassembling it right away. The reason is often very commonplace. The main thing is to make a thorough external examination.
It is necessary to check the presence of power in the network, the reliability of the plug-to-socket connection and the integrity of the power cord. The latter, quite often fails due to bends or exposure to sharp objects. If damage is found on the cord, it must be replaced. As a last resort, splice repair is possible. In this case, special attention should be paid to the insulation of the wires.
The noise and vibration of the juicer are the result of improper assembly of the device or foreign objects falling into the drum.
The hum of the motor when the drum is standing indicates that the adapter coupling is overtightened. Usually the problem is corrected by loosening this part.
Other malfunctions will most likely require disassembly of the device.
The device of any electric juicer is not complicated. An obligatory attribute is an electric motor, which supplies the lion's share of malfunctions. This household appliance uses motors collector type and asynchronous ... Each of them has its own disadvantages and advantages.
The former allow to reduce the size and weight of the product, but are not designed for long-term operation and require cooling, which is provided by the impellers mounted on the shaft. Asynchronous electric motors are more efficient, but take up more space and, accordingly, are distinguished by increased mass.
The motors mate with the centrifuge drum or rotate the auger. Depending on the type of juicer (centrifugal or screw), the connection is carried out by couplings or gears. These parts are usually made of plastic and are the cause of malfunctioning juicers. As a rule, manufacturers always provide a stock of these parts by including them with the juicer they sell.
The juicer motor is very finicky and fails when:
voltage drops in the network;
long-term work under heavy load;
moisture penetration into the engine compartment.
Damage can be caused by normal wear and tear.
For preliminary disassembly of the juicer, use the instructions attached to it. If one is not at hand, then you need to use logic.
Attention! You should never use excessive force when disassembling household appliances. This leads to the destruction of the case and mountings and is fraught with further problems. Manufacturers usually take care of customers and make this procedure as easy as possible.
After separating the remaining units from the engine compartment, they begin to disassemble it. A Phillips screwdriver is usually sufficient for this. After disassembling the compartment, the engine is freed from the couplings.
The speed switch and radio components included in the electric motor circuit are pre-checked. This operation is performed by the tester.
Even a superficial inspection of the motor can tell a lot about a malfunction:
Motor arcing and heat build-up are the result of abrasion or destruction of brushes (for collector motors). Replacing them will correct the situation.
Obstructed rotation of the armature shaft signals a failure or contamination of bearings ... To remove them, you will need to disassemble the engine and use a puller. When assembling, pay special attention to the cleanliness of rubbing and rotating parts, as well as their lubrication. Regular cleaning and lubrication will help prevent this malfunction.
The smell of burnt insulation and blackening indicates burnt winding ... Such a breakdown cannot be eliminated at home and requires the replacement of the entire unit.
Of all the points, only the last one is critical. All the rest are restored on their own, even with relative knowledge of electrical engineering.
Given the wide variety of juicers produced and produced today, it is difficult to describe all possible malfunctions of these units. Each of them may have their own specific case. But if you study the reviews of the owners of both domestic and foreign models, we can say that the main breakdowns are very similar.
Some useful information about the repair and maintenance of mechanical and electric juicers can be found in the video.

After surfing the Internet and getting a lot of information, I looked for an inexpensive Moulinex Frutti Pro Plus juicer.
This miracle of technology was purchased in one of the Kaluga stores, but it did not please me for long. At first, it turned out that the filter itself does not clean itself (at least when pressing the chokeberry), so you constantly have to remove and clean it by hand.And when the next portion of rowan was squeezed out, the juice-squeezer turned off by itself and did not want to work. At first I thought that the thermal protection of the engine worked, but after an hour, the equipment still did not turn on.
And this is after 2-2.5 hours of work from the date of purchase, I am furious. At first, I didn't want to leave it in the box, take it back to the store and pop it at the saleswoman who praised it to me.
Then he cooled down a little and gave up this thought - somehow not like a man (and the saleswoman is pretty, it's a pity), washed the broken device with the thought of how I would carry it under warranty and how they would deny me this very guarantee, in general I scrolled in my mind options for a verbal skirmish (I had no doubt that it would be).
On the same day I went to see my aunt, took a juicer from her, and the next day gave the remnants of mountain ash. I didn’t take my sokozhmalku to the service, then there’s no time, then I’m reluctant to lug a large box in a transport, and it’s too far on foot. So she got it until January, and that's when I started to repair it. She died quietly, no sparks, no specific smell of burnt insulation, so I decided that either something had fallen off, or some part of the electrical circuit was out of order. I unscrew the four screws on the bottom cover and remove it.
Yes, a very complex electronic product.
Electronics ”of this juicer consists of:
2.operating mode switch low speed / high speed
3.diode, when the switch contacts are open, the diode passes only one half-wave of the mains voltage to the motor, so the motor runs at half its power, when the contacts of switch 2 are closed, all the current flows through these closed contacts in full and the motor operates at rated power
4. switch that actually turns on / off the device I want to note one discrepancy right away: the tag on the case says 400W, the engine has an inscription 600W, I didn't check which inscription is true, maybe then somehow.
Having called the entire circuit with a tester, I found a place, an open somewhere between the terminal going to the noise filter and one of the rotor brushes. So all the same the engine.
He unscrewed the four screws securing the motor to the case, unscrewed (clockwise) the drum from the motor shaft, during this operation, on the other side of the motor, a slot was made on the shaft for a screwdriver, and pulled the engine out of the case At first I thought that a thermal fuse was hidden in the stator winding, which died ...
I opened the heat-shrink tubing and found a coil that filters interference. Then I accidentally pulled the wire from this coil onto the brush, and it turned out to be torn off from the brush holder (the core was torn off, and the insulation was clamped by the brush holder petal). So this is where the dog rummaged. I soldered the wire, put the coil in heat shrinkage, checked it - it works.
I put everything back together, checked it again - and it works like that too, well, that's nice.
The question of whether a juicer can be made by hand is primarily of interest to the owners of summer cottages and backyards, who annually harvest fruits and berries, which must be quickly processed and saved. The fact that juices obtained on their own are much tastier and healthier than those sold in stores adds even more relevance to this issue.
Any owner of a garden plot can make such or a similar screw press
Today, purchasing a juicer of any performance does not present any particular problems, but such equipment is not cheap. That is why it is advisable to make a juice press with your own hands, especially since the design of such devices is not very complex.
Before wondering how to make a juicer with your own hands, you should understand the principle by which it works. To get juice from fruits or berries, you need to put pressure on them.By their design and operating principle, juicers can be of the following types:
mechanical devices;
hydraulic;
electrohydraulic;
pneumatic.
The simplest in design are mechanical-type juicers, which are most often made by home craftsmen with their own hands. The principle of operation of such devices, which are not distinguished by high performance, but are quite suitable for domestic use, is based on the fact that a piston acts on the raw material, the pressure on which is exerted by a screw mechanism. Fruits and berries are loaded into a perforated basket, through the holes in the walls of which the finished juice flows into the storage tray.
Screw press device for juicing
The screw press basket can be made of stainless steel sheet or hardwood. Wood baskets are drainage grates, consisting of two halves connected by metal hoops. The screw presses of the above design can even be used to squeeze apple juice. In this case, the raw material is loaded into the basket of such a juicer in a finely ground form.
As mentioned above, the most simple in design and, accordingly, easy to manufacture are mechanical presses for squeezing juice. To make such a do-it-yourself apple press, on which you can process other fruit and berry raw materials, you will need the following consumables and tools:
stainless steel sheet;
channel or square metal pipe with a cross section of 40x40 and a wall thickness of at least 3 mm;
pipe with a diameter of 16 mm;
a rod on the surface of which a thread is applied;
screw;
board 30 mm thick;
welding machine;
grinder and electric drill;
hammer;
hacksaw for metal.
Before you start making a homemade apple juicer, it is advisable to find drawings or drawings of such a device on the Internet or draw them yourself. It will also be useful to watch a video on the manufacture of a juicer, which shows such a process in all its details.
If you decide to make a juicer for apples or other fruit and berry raw materials, start by making a perforated basket into which the fruits for squeezing will be loaded. For such a basket, a stainless steel sheet is used, on which it is necessary to first mark the locations of the future holes. After marking, the holes are drilled and then countersinked with a larger diameter drill to make them tapered. The purpose of these holes is to allow juice to flow out of the basket after it has been squeezed out.
Billet made of stainless steel sheet with drilled holes
It is necessary to form a cylinder from a sheet of stainless steel with already drilled holes and weld the formed joint. To prevent the juice coming out through the holes in the walls of the perforated basket of the juicer from splashing and evenly flowing into the collection tray, it is necessary to make a protective cover, for which a sheet of stainless steel is also used. To manufacture such a casing, the diameter of which should exceed the cross-sectional dimensions of the perforated basket, the stainless steel sheet is bent into a cylinder and the formed seam is also welded.
Bending the workpiece into a cylinder
Once the perforated basket and juicer cover are ready, you can start making the frame. Focusing on the drawings or drawings of your homemade product, it is necessary to cut pieces of the required size from a channel or square pipe, from which the frame structure is welded. In order to ensure the stability of the resulting structure, legs are welded to its lower part, also made of a channel or a metal square tube.
The lower part of the frame made of a shaped tube
In the upper part of the resulting press frame, it is necessary to drill a hole into which the nut for the screw mechanism of the device is welded. Depending on whether you need a large or small press for juicing, the dimensions of the perforated basket and the frame, which serves as a supporting element for the entire juicer, are selected.
Upper frame with screw nut
As a piston through which the screw mechanism will exert pressure on the raw materials loaded into the basket, you can use a wood board (a circle of the corresponding diameter is cut out of it).
The final procedures for manufacturing a juicer of the proposed design are welding the handle to a screw rod, through which it can be rotated, and installing the basket and protective casing on the storage tray.
The press is almost ready, all that remains is to paint the frame
If you are not satisfied with the power and efficiency of a conventional screw press for juicing, then you can make your own juicer, which will be driven by a conventional mechanical or hydraulic jack. It should be borne in mind that even the simplest squeezing presses, the driving device of which is a jack, can extract up to 70% of the juice from the total mass of raw materials loaded into them.
And in conclusion, a small video about the nuances of the manufacture and operation of an already assembled homemade juicer.
