Centrifugal juicer working principle. Which juicer is better - auger or centrifugal. What you should pay attention to

Juice is made only from oranges, lemons, grapefruits, limes and tangerines. The fruit should be cut in half and placed with the flesh down on the ribbed cone. When you press on the fruit from above, juice forms and flows into the reservoir.

Advantages. Compact and easy to use. Cheaper than centrifugal and screw.
Disadvantages. Not universal, only suitable for citrus fruits. Juice cannot be stored for future use.

How to choose

Citrus juicers come in manual, mechanical, and electric.

Manual ones are the cheapest, but ineffective: they require more fruit for one glass of juice.

Mechanical ones work due to the lever, which allows you to apply less physical effort and get more juice.

Electric juicers allow you to squeeze out the maximum juice. Their power is usually 20–80 watts. The more powerful the device, the faster the juice will be.

Pay attention to whether the kit includes a lever that holds the fruit during spinning, and nozzles of different sizes. You need at least three of them: a small attachment for lime and lemon, a medium attachment for an orange, and a large attachment for a grapefruit.

Another useful feature is the presence of a reverse. When it is there, the motor rotates the juicer attachment not in one direction, but in both directions, and more juice is obtained from the fruit. Expensive models have a pulp control function. It can be adjusted by making the juice thicker or vice versa.

The capacity of such juicers usually does not exceed 1-1.2 liters, because citrus juice quickly oxidizes and loses beneficial features... It should be drunk fresh, within 5-10 minutes after preparation. If you are making just a glass of juice at a time, choose a smaller juicer. If you are preparing juice for the whole family, take it with a larger container.

Suitable for making juices from hard fruits and vegetables. Fruits are loaded into the neck, a disc grater inside crushes them into small particles, after which they go to a centrifuge-separator, where juice is released from the resulting gruel.

Advantages. The main advantage of the centrifugal juicer is its productivity. It works quickly and handles large quantities of fruits and vegetables. Juice can be made with a margin - for example, for the winter.
Disadvantages. Works loud, not suitable for soft fruits (banana, apricot, mango, papaya). The juice is obtained with a foam, and it contains fewer vitamins than whole vegetables and fruits, since due to the high spin speed, it heats up, interacts more with oxygen and oxidizes faster

How to choose

There are two types of centrifugal juicers: cylindrical and conical separators. The cylindrical one gives more juice, but during operation it must be stopped and cleaned of cake (residues of fruits and vegetables). In new models, manufacturers are increasingly abandoning this design in favor of a tapered one.

The conical separator squeezes out the juice a little worse, but works without stopping: the cake is automatically removed into a special container. It is still difficult to wash such a juicer: you need to disassemble it, wash all removable parts, and then reassemble. There are exceptions - for example, the SC-JE50S45 juicer with a self-cleaning function. After use, you need to switch it to Clean mode, and a special scraper will clean the filter itself.

Pay attention to the power, volume of containers and dimensions of the juicer. The more juice you plan to make, the higher these parameters will be. Do not chase performance and assess your needs sensibly: you may overpay for too much power that you do not need.

If you need to process 30 kg of apples every summer, take a juicer with a capacity of 1,500-2,000 watts, and if you just like to drink a glass of juice in the morning, you can get by with a capacity of up to 200-500 watts.

But with the size of the juicer neck, everything is unambiguous: the larger it is, the better. Whole fruit can be loaded into a 7–8 cm diameter neck without wasting time slicing.

Suitable for all fruits, vegetables, herbs, nuts and sprouts. By the principle of work, they are similar to a meat grinder: fruits and vegetables are crushed using an auger - a mechanism similar to a screw. Juice is formed under pressure, after which it is separated from the cake and fed into a container.

Advantages. They make cold-pressed juice. During cooking, it does not heat up or oxidize, it can be stored in the refrigerator for up to two days. It is richer, sweeter and contains more pulp.
Disadvantages. Less powerful than centrifugal ones and slower. They are quite difficult to disassemble and wash, the neck in most models is narrow.

How to choose

Screw juicers differ in body materials, capacity, volume of containers for juice and cake and additional functions.

The stainless steel case is more reliable and durable than the plastic one.

The minimum size of containers for juice and cake is 350 ml. Power ranges from 200 to 400 watts. If you will be making juice for the whole family - take the 400 W model with a 0.8-1 liter container and a liter juice container, like the Scarlett SC-JE50S43. If one glass of juice is enough for you in the morning, the compact Scarlett SC-JE50S39 juicer with a 350 ml container and a 200 W power will do.

Look for models with a wide neck; they are easier to use. For example, the Scarlett SC-JE50S44 juicer has a 7.5 cm neck diameter, while the Scarlett SC-JE50S40 has 8 cm diameter.

To clean the auger juicer, you need to take out all the removable parts and rinse them under water. The set includes a special brush for cleaning. For convenience, some models are equipped with an easy disassembly system - when parts are removed not one by one, but simultaneously. This allows you to do everything in the sink without messing up the kitchen.

Some auger juicers make not only juices and smoothies, but sorbets as well. In the Scarlett SC-JE50S41 juicer, sorbet is made in the same way as juice: you throw frozen fruits into the neck, and at the exit you get a healthy dessert.

Short

Auger juicers are the most functional and do the most healthy juice... They are suitable for all fruits, vegetables, herbs and nuts, but are expensive.
Centrifugal juicers are the most powerful and perfect for gardening crops. But they consume a lot of energy, work loudly, do not store all vitamins, and are only suitable for hard fruits and vegetables.
Citrus juicers are the cheapest and most compact, but not suitable for all fruits.

Eco-friendly home: B recent times we increasingly do hard choice between freshly squeezed juice and juice from the package. Of course, the first option is much tastier and healthier. But in order to squeeze the juice, you need an auger juicer, which not everyone is ready to buy. And it's not even a matter of money, since individual models in online stores have a fairly reasonable price.

Recently, we are increasingly making a difficult choice between freshly squeezed juice and juice from a package. Of course, the first option is much tastier and healthier. But in order to squeeze the juice, you need an auger juicer, which not everyone is ready to buy. And it's not even a matter of money, since individual models in online stores have a fairly reasonable price.

The fact is that a juicer is a technique that is not an obligatory kitchen accessory, and for many people buying it is something superfluous. But if you still want to start from tomorrow (or even from today) healthy life, then you simply cannot do without this device.

Next, we will tell you how to choose correct device for apples, for tomatoes, for berries, for grapes, for currants, etc. Also, we will determine which is the best model for different volumes.

Types of juicers

Despite the huge variety of models offered by modern manufacturers, all devices for obtaining fresh juice can be divided into screw and centrifugal (universal). The second type is quite common, but in our case it is nevertheless necessary to use the first type, intended for private use. It is also worth noting that garden and home auger juicers can be divided into manual, electrical and mechanical.

A cheap manual auger juicer is a kind of ordinary meat grinder designed for working with fruits. In this case, in a hand-held apparatus, the auger will not have a spiral, but a conical shape, for greater productivity.

In principle, if you have a special attachment, then a homemade meat grinder juicer can be used to squeeze juice, although this is not always convenient. From apricots and plums, you are more likely to get fruit puree, not juice, but these are nuances.

Inexpensive mechanical devices, unlike manual models, have a more complex design that allows them to work like a conventional press. In this case, the production of juice is carried out using a special lever, which creates pressure in the device.

Electric squeezers are machines with an electric motor, which, under the action of a current, rotates a grater, rubbing vegetables and fruits placed in a container. At the same time, the mechanism retains the pulp, which is an additional advantage of this type of model. it the best way of all the above, and most of these devices are produced not by Russia, but by Korea. To be convinced of the correctness of my words, I recommend looking at the online reviews, comparisons, tests and ratings, of which there are a lot.

Additionally, electrical devices can be divided into three subtypes: household, professional and industrial.

The first subtype is intended for use in conventional kitchens.

The second subtype is used in restaurants, bars and cafes where large volumes of juice need to be produced quickly.

The third subtype is used in large enterprises that process fruits and vegetables on an industrial scale.

Finally, a classification can be made by the location of the auger. In particular, there are horizontal and vertical squeezers. Which option is more convenient for you? Only you can answer this question. I want to note that on sale today you can find the so-called twin-screw juicers, which means that each auger rotates in different directions. The effectiveness of such devices increases significantly.

The principle of operation of auger devices

The auger juicer, reviews of which you can always find on the nearest forum, is divided not only by type, but also by the principle of operation, although the result will be the same.

1. If we talk about a mechanical squeezer, then the principle of a conventional press is used here. We put the vegetable or fruit under the press mechanism, use the lever and squeeze the juice from the fruit.

2. The hand squeezer adopts the cold-pressing principle, squeezing out the juice with a screw. The press is activated manually. The only thing that separates the pulp from entering the glass is the grate. The smaller it is, the cleaner the juice will be. But if the cells are too small, not very much juice will get into the glass.

3. An electric squeezer works on the principle of a hand-held device, with the only difference that the auger does not rotate with its own hands, but with electricity, which copes with the work much more efficiently. The auger first grinds fruits and vegetables into a gruel, after which, under the influence of pressure, juice is extracted from the gruel.

Specifications

The characteristics of screw units include capacity, power, spinning technology, material, neck size, weight and dimensions.

Weight and dimensions determine not only the convenience of storing devices, but also the stability of the device, as well as the absence of vibrations.

The material is important as it determines durability and usability. If the body can be made of plastic (necessarily hard, glossy, certified), then the internal parts must be made of stainless steel, which will affect the usefulness of the juice.

The power of the model determines the productivity of the squeezer, speed, and time of continuous work. Power does not affect the quality of the juice. The power of household devices is up to 1 kW.

The screw rotation speed in modern devices reaches 7080 rpm. - The capacity of the devices ranges from 400 to 1200 ml, and is selected depending on personal needs.

The diameter of the neck will determine the size of the pieces that can be placed in the container.

Reversibility. If the model has a reversibility (technology of alternating the direction of rotation), then you can dramatically increase the performance of the device.

The diameter of the holes in the grid. As already mentioned, the larger the grate, the thicker your drink will be.

Advantages of auger models

Of course, screw extractors have advantages and disadvantages, regardless of whether it is produced by a domestic (Russian, Belarusian) or foreign (Korean, Finnish) manufacturer.

The main advantages of this type of model is their versatility. To obtain juice, you can use any fruits and vegetables, and even those that are not taken by the universal or centrifugal technique.. You can juice berries, fruits and vegetables, herbs and greens. Depending on your preference, the juice can be pitted or pitted.

Another plus is the richness of taste and the highest quality of the final product. The finished juice retains the maximum amount of vitamins, enzymes and minerals, which can be explained by the lack of powerful aeration, typical for centrifugal models.As a result, the resulting beverage is less oxidized and suitable for long-term use.

Also, screw models have high level juice yield (up to 85%). They are comfortable, practical, reliable, which is explained small amount used parts. Finally, don't forget about the low noise level, which is a significant benefit for many buyers.

Disadvantages of screw models

As for the shortcomings, here we can highlight the low quality of apple and pear juices, especially from overripe fruits. As a result, you will get fruit puree, which, although it will be tasty, simply cannot be called juice. Also, when working with horizontal models, you will have to cut the fruit into at least four pieces.

Finally, modern models with two augers are time-consuming to clean up after use due to their complex design.

It will be interesting for you:

Lack of various vitamins and minerals and a crazy, exhausting body rhythm of life is a common occurrence for modern man any age. An excellent source of those vitamins can be freshly squeezed juice from vegetables or fruits. Moreover, the latest models of juicers are able to squeeze nectar even from seeds, sprouts and greens. Any Appliances undergoes constant improvement, updating, which contributes to an increase in the number of models. For home production of fresh juices, there are centrifugal and screw juicers. The latter have a more gentle spin mode and some advantages. We will find out which ones below.

What is a screw juicer

The basic principle of the auger machine is the production of juice by cold pressing. It is in the absence of warm air that the secret of obtaining juice richer with vitamins lies - in the warmth it oxidizes and useful elements simply disappear. The advantages of the auger juicer do not end there, but only start:

the equipment has increased productivity and versatility, which will allow you to work with complex and solid products, such as seeds, nuts, herbs;
work is almost silent;
the operating speed of such an apparatus is almost twice that of the centrifugal type;
very easy maintenance - just a glass of water inside and start work.

As the name suggests, this juicer works with an auger. In addition to it, there is a press mechanism and a bowl. The principle of operation of the apparatus is similar to a meat grinder - when loading products, they are captured by the auger blades, pressure by means of a press, juice filtration through special membranes, separation of the finished, strained juice into a juice receiver, and cake into a bowl.

Considering that the juice production process takes place practically with the help of natural pressure and grinding, there are no actions in the apparatus that can heat the air. Warm air oxidizes some foods and often, when using centrifugal models, it was possible to get sour juices. In screw devices, acid will be exclusively a feature of the loaded product.

Types of screw juicers

Juicers equipped with augers have two types of construction and can be vertical or horizontal. In addition to their appearance, they differ in additional elements, efficiency and convenience:

Horizontal models will produce juice if the products are "pushed" by special pushers. This procedure slightly increases the time it takes to juice, which can be a disadvantage. But the clear advantage of these models is the better production of juice from herbs or herbs, as well as work with solid products - nuts, vegetables, seeds, berries with seeds.
Vertical screw-type juicers are able to pick up and process incoming products on their own, they do not require pushers. Such models are more compact and efficient.

IMPORTANT! Some large whole foods cannot be loaded into horizontal models - they will have to be pre-cut.

In addition to design features, juicers may differ in the number of augers themselves - there may be one or two.

The difference between a screw juicer and a centrifugal one

In order to understand the main differences between the two types of juicers - screw and centrifugal, you need to understand the principle of the latter. The products placed in centrifugal models are first crushed to a state of porridge, which is then distributed along the walls of the centrifuge. The centrifuge, in turn, rotates very strongly, letting juice through its walls and leaving cake on them. It is not surprising that there is a lot of noise from such work, but the output of the finished juice is less than in auger devices. If we compare the characteristics of both models, we can highlight the following indicators:

In general, even insignificant disadvantages of devices with augers can be easily converted into convenience. For example, juicing pulp can be desirable for children, and grinding soft and overripe fruits can make a great puree.

What criteria should be considered when choosing a juicer

In order to purchase a juicer that will perform all the required work and produce a product of the required quality and consistency, you need to decide in advance on the purpose of purchasing it. Vertical versions of screw models differ in more compact sizes, and in the kitchen, most often, there is little space for storing large-sized household appliances. If the goal is to get unusual juices from unusual ingredients - nuts, herbs, herbs - the horizontal model will do. There are other parameters that you should definitely pay attention to:

ATTENTION! Some manufacturers may resort to gimmicks and emphasize the low noise level of their models. In fact, all augers have a low noise level - 25-30 dB, which is comparable to talking in a quiet voice.

When choosing the right model, of course, you will have to be guided by the brand name, price and reviews. If freshly squeezed juices are a new idea to diversify your diet, you should not immediately choose an expensive and multifunctional model. It is quite possible that adhering to the principles of proper and healthy nutrition will soon become boring, and the house will not have enough fresh fruit for healthy juices - then the device will have to be hidden in the closet. But the general capabilities of modern models - the processing of herbs, seeds, nuts - can significantly diversify the diet, recipes, and serving many dishes. Perhaps it's time to change the usual associations of juicers with a glass of orange juice and use their other features.

Having a juicer at home, you can independently prepare a drink from any fruits, vegetables and berries without overpaying in stores for packaged products. What is the device of a household juicer, what types are there, and how does the device work? Let's take a closer look.

All modern juicers are divided into 2 types, differing not only in purpose, but in properties:

Screw juicers work according to the following principle: an axis resembling a spiral rotates, as a result of which the fruit, which was placed in the bowl, is crushed and moved into the compartment, where the new pulp pushing from behind is squeezed out through the fine grate, filling the glass with juice. The efficiency is slightly better than that of the canonical centrifugal model, but not as good as that of the cylindrical type.

Advantages auger juicers:

Due to the low speed of rotation of the shaft, the juice does not oxidize, which in turn allows you to preserve all the useful microelements.
The wide, large neck prevents the fruit from falling back out, as is often the case in centrifugal juicers.
Low noise and vibration levels.
The ability to juice almost any product: leaves, grass, seeds, pomegranate - using the slow press method.
Possibility of long-term operation without stopping.
Self-cleaning function.

The cost of auger juicers is an order of magnitude higher than that of centrifugal ones, due to the ability to perform a wide variety of work.

Choosing a citrus appliance

Due to the fact that citrus fruits have a thick peel and many thin veins, a juicer for them must have special characteristics:

The power of such devices varies from 20 to 100 watts. The smaller it is, the slower the glass will be filled with juice.
The volume of the container is also important. Most often it is no more than 1.2 liters. When choosing a suitable tank volume, you should rely on the number of members in the family.
Please note that the spout in the juicer has great importance... Choose one that won't spill juice when you fill your glass.

Many citrus juicers have some additional features:

Direct juice flow allows the beverage to be poured directly into the glass without accumulating in the reservoir.
Reverse mode, which allows the cone to rotate to the right and to the left, increasing the efficiency of the device.
A system with which you can increase or decrease the density of the juice. This is possible due to the presence of slots in the nozzle through which the drink is poured. The larger they are, the thicker the drink.
Additional attachments in the kit allow you to use fruits of various sizes.
The presence or absence of a lever that holds the fruit while wringing it out adds safety to the device.
The scale that determines the level of the liquid is convenient if it is necessary to measure the volume of the squeezed juice evenly.

We select a universal type juicer

Before purchasing a universal juicer, you should familiarize yourself with some of the features of such devices:

Give preference wide neck oval shape. The narrower it is, the smaller you will have to cut fruits and vegetables, which will undoubtedly take some time.
Before purchasing an appliance, decide for yourself which separator type you prefer cylindrical or canonical. On the scales is the convenience or maximum of squeezed juice from the fruit.

Universal models have additional functions:

Before buying, ask the seller how many revolutions issued by a centrifuge. The optimal speed of its rotation is 7000-9000 rpm. You should not listen to consultants pushing you to buy an expensive model that can spin the centrifuge up to 20 thousand revolutions. This is nothing more than a PR stunt.
It will be useful to have speed regulator... The harder the fruit or vegetable, the more speed it will take to get the most juice out of the juice.
Centrifuge mesh material it is preferable to choose stainless steel, with many small holes, the more there are, the better.

Conclusion

Having decided on your tastes and preferences, having learned the device, types and operating principle of the juicer, you can decide which model is right for your family. A universal model capable of extracting juice from almost any fruit or a device exclusively for oranges and grapefruits - this is your choice and your opinion, with which no one will argue.

A juicer should be in every home where people want to eat right and tasty. With it, you can make vegetable and fruit juices, then we will try to understand the variety of this technique and the features of its choice.

Types of structures

There are three main types of juicers:

For citrus... This is a simple equipment that allows you to juice citrus fruits. Their principle of operation is simple: a half of the fruit is put on a rotating nozzle, which is pressed by hand or a special lever and the juice is squeezed out.

Universal (centrifugal). This technique allows you to extract juice from vegetables, fruits and berries, using a disc grater, first they turn into a homogeneous mass. After that, with the help of a separating device, the juice is separated from the cake. Their separator can have a cylindrical or conical shape.

Auger... With the help of this equipment you can squeeze juice from any vegetables and fruits, as well as greens and herbs. It works according to the technology of cold pressing and at the same time a minimum amount of waste is obtained. The principle of operation of such a device is the same as that of a meat grinder, it also has one or two screw augers.

By the type of drive, such devices can be electric and manual. An electric juicer is more efficient but requires electricity. Manual devices are non-volatile, the juice is cold pressed, so it is more useful, but you will have to spend a lot of energy to get it.

Features of the device

The manual auger juicer has two main parts, the auger and the perforated cone. To prevent juice splashing, a protective cover is put on the cone, which can be plastic or metal. Outwardly, it looks like an ordinary meat grinder, it also has a handle and a body. The auger is made in the form of a conical screw, at the beginning of which there are wide blades, and towards the end they decrease.

The universal juicer consists of an electric motor and a wide cylindrical or conical separator with a knife at the bottom. In addition, such a device has a body, a control unit, it can be equipped with bowls for collecting juice and cake.

Operating principle

The principle of operation of the auger device will be as follows: the raw material, falling on the rotating auger, is first crushed, and then fed into the squeezing unit. During its passage along the screw, compression occurs and juice is released, which through the perforated cone enters the substituted container, and the cake is removed through the hole located at the outlet of the cone. In mechanical devices, the auger is operated by hand, there are electrical options in which there can be one or two augers rotating in opposite directions.

During the operation of the universal juicer, vegetables or fruits enter the separator, here they are first chopped with a knife, and then, under the action of centrifugal force, they are pressed against the perforated walls of the separator. The resulting juice flows down the walls and falls into a special bowl, while the cake remains on the walls. There are machines for which the cake must be removed manually, and for some this process is automated.

Areas of use

For household use... Such equipment is intended for home use, it is not designed for long-term use and for obtaining juice in large quantities. Household appliances are suitable for a family of 3-4 people, they are small in size and affordable.

Professional equipment... Such devices have great power and speed of operation. They are intended for use in cafes, bars, restaurants, have high performance and beautiful appearance, as they are used in full view of visitors. They are not suitable for an ordinary family, as they have a high cost.

Industrial apparatus... This equipment is large in size and powerful. It is intended for the processing of fruits and vegetables on an industrial scale. Such devices are highly versatile, the requirements for their outward appearance low, as they are used in closed production halls.

Features of choice

Specifications:

A universal juicer must have at least two speed modes. This allows you to get juice from a variety of vegetables and fruits. High speed is used for hard food and low speed for soft food. The presence of more than 3-4 speeds is an excess and practically does not affect the quality of the spin, rather it is an advertising move by the manufacturer.
The number of revolutions, the optimal one is considered to be 8-10 thousand per minute, at lower revolutions, it will take more time to squeeze the juice and more electricity will be spent, and if large, the efficiency increases insignificantly, but the consumption of electricity is noticeable. The auger juicer and citrus fruit equipment operate at lower rpm.
Power, a citrus appliance has a low power, usually it is within 30 W, while universal equipment has a power of up to 700-1000 W, and for augers it can be even higher.
The material used, for the manufacture of the strainer, stainless steel is used, the body can be metal or plastic. All plastic parts that come into contact with food must be made of food grade material.

Convenience:

The presence of a removable container for cake.
The diameter of the filling hole should be about 9 cm, this allows whole vegetables and fruits to be placed.
Availability safe mode, will not allow the equipment to start if it was assembled incorrectly.
The presence of the “drop stop” system allows, after the device is working, to turn the spout through which the juice flows upwards, so the drops will not fall on the table.
The pusher, with the help of which the products move along the feed neck, can be hollow and used as a measuring jug.
The presence of a separator for separating foam, will allow you to get pure juice, which no longer needs to be filtered.
The rubberized feet help the appliance to stick well to the tabletop.

Advantages and disadvantages

Let's consider separately the pros and cons of auger and centrifugal juicers.

Advantages of auger devices:

The work takes place at a low speed, so the juice does not oxidize and more nutrients are stored in it.
This juice can be stored for up to 2 days without losing its beneficial properties.
They generate little noise during operation.
Such a device can operate continuously for a considerable time.
Has a long service life.
There is little waste.
You can squeeze the juice from herbs, herbs, wheat, oats, etc.

Such devices also have disadvantages:

The juice turns out to be rich and there is a lot of pulp in it, so if you want to get a refined product, then it must be passed through a sieve.
When using overripe fruits, you will not get juice, but puree.
To obtain tomato juice, horizontal devices are suitable, since vertical ones do this task poorly.

Advantages of centrifugal or universal apparatuses:

They operate at high speeds, so the spin speed is high.
Affordable cost.
Ease of operation, you just need to load the products through the neck, and then the device will grind them and squeeze out the juice on its own.

Among the disadvantages of such equipment, the following should be noted:

Since the work is performed at high speeds, the juice overheats, therefore it loses some of its useful properties.
You cannot store such juice for more than 20-30 minutes, as it oxidizes and becomes tasteless and unhealthy.
Large consumption of products, so the cake is juicy.
