When purchasing a juicer in a store, you can be faced with the problem of choice. Manufacturers are a variety of models that differ in price, design and features. Often, you can get lost in this variety of goods. How do you determine what is best for you, auger or centrifugal juicer? To answer this question we need to examine in detail all the details.
All units to separate the liquid from the vegetables and fruits can be divided into two main types: centrifugal and screw. The essential difference between them, which affects the performance and the quality of drinks, is the principle of their action. Screw devices juice extracted by cold pressing, which is considered the best for the preservation of useful properties of the product. The centrifugal fluid isolation occurs by rapid rotation of the centrifuge.
The design of the screw device is similar to a conventional meat grinder. The basic mechanism here is a spiral-shaped shaft, which is called the screw. Spinning, he grinds the fruit in the mush. Under the pressure of the shaft is extruded through a metallic mesh in the form of juice fed into the glass.
The filter cake is discharged into the waste compartment. This design allows you to receive the maximum amount of a substance from the fruit. In this case, the drink will be dense, with bright taste and cake - dry, squeezed to the last drop.
Auger juicers are able to cope with the results of any hardness. They are easy to grind not only carrots, beets and radishes, but also plants, coffee beans and other products. With these devices can be prepared juices uniform consistency of fruits and berries containing small bones.
This device is perfect to make a thick and rich tomato juice.
The screw device may be:
- manually operated,
- electrical single-screw,
- electric twin screw.
Hand-held devices resemble a meat grinder not only constructive, but also appearance. They are controlled by a knob, rotating auger. Electrically actuated engine that operates at low speed. Electrical equipment can be equipped with two shafts for better grinding of the fruit. Sometimes they are fitted with reverse function (reverse movement), in order to increase the efficiency of extraction.
The screw type devices shafts can be placed horizontally and vertically. Vertical devices are more compact, they are used for quick, a few glasses of drink. Due to their design, they do not really do well with fruits that have seeds, and greens.
The centrifugal juicers shredding fruits and vegetables by means of a grater disc disposed in the bowl unit. When the device is rotated at a very high speed. The fruits are in the bowl, quickly converted to puree the state.
Next, this mass is fed into the separating compartment where the centrifugal force is divided into a liquid and a cake. The pulp is pressed into the wall of the bowl, and the liquid flows down through the holes. A large part of the pulp of the fruit goes to waste. Juice is obtained a transparent, low concentration.
These devices can process fruits and vegetables of varying stiffness both soft and hard. However, if the fruits are pits or seeds, they are not crushed, but remain in the separator, and clog up the filter.
The shape of the separator in centrifugal juicers extraction efficiency depends. The conical cake automatically removed in the waste compartment. But at the same spin it is made not to the end. The devices having a cylindrical shape of the separator is released and more liquid remains less waste, but need expeller to remove manually, periodically removing compartment.
Advantages and disadvantages
We found out the difference between the auger juicer from centrifugal. Because of the significant difference in the design of devices of different quality drinks are obtained with different extraction percentage. Advantages and disadvantages of present and those in other models. Therefore, to determine which juicer is right for you, centrifugal or screw, you'll be able to.
The main advantage of screw devices is a high percentage of the obtained product (slightly less than 100%). For a drink you spend much less fruit than it would be in a centrifugal device. Another important factor may be considered useful to produce juice. In view of the fact that the auger juicers, the principle of cold-pressed, they no longer contribute to the preservation of useful properties of the final product.
The beverages prepared in this manner, vitamins are not destroyed and do not undergo oxidation in the centrifuge. Ready juice contains the most valuable substances necessary for human health. Keep beverages obtained by cold pressing, it is possible within two days.
In addition, the following benefits of using auger juicer:
- the ability to handle any, even the most solid results, as well as containing grains and bones;
- silent running;
- reliability and durability;
- duration of continuous operation (up to 60 minutes);
- the presence of the self-cleaning function.
One of the drawbacks is that the soft fruit varieties such juicer turns to mush. To prepare the liquid beverage would have to go a few times pressing operation. Among other disadvantages:
- low speed preparing a beverage,
- relatively high cost,
- lack of variety models.
The main drawback of centrifuge models considered oxidation of the juice during processing, which leads to the destruction of vitamins. In addition, the liquid is heated as a result of rotation of the centrifuge, which also allows you to save valuable substances.
In addition to the disadvantages include:
- low spin rate (50%), which significantly increases the consumption of products;
- creating large amounts of foam during the juicing;
- inability to handle very hard components and fruits with small granules.
The undeniable advantages of centrifugal juicers are:
- High speed;
- the large number of low-end models, with a low cost;
- ease of use.
Criterias of choice
When purchasing a juicer in the shop should pay attention to the following criteria:
- display capacity;
- the material from which the housing is made;
- the size of the intake tray;
- reliability of components;
- additional functions.
First of all, you need to determine how much the drink you want to use every day. If you drink juice with your family, prepare cocktails out of it, and so on. E., You need a more powerful juicer with good performance. On the spin speed directly affects the capacity of the device.
For domestic vehicles centrifugal sufficient power rating of 500-600 watts, but it can be more. Screw use small momentum, so such a device may have a 180-200 W, for efficient extraction.
If you need more than 2-3 glasses of beverage a day, pay attention to the juice collector. It is better to choose a more capacious reservoir of one liter or more. In such a case must be large and the cake discharge compartment.
Think about what kinds of juices you will make. Such fruit as pomegranates, grapes, tomatoes, and so on. N. recommended to treat in a screw device. It is also more suitable for the processing of citrus. Then, for them it will need the appropriate nozzle.
Screw multifunctional device. If special attachments you can cook them in pasta, stuffing, seasoning to create, to grind the coffee beans. Also they can be used to easily mash, pies, pasta.
Choosing a good instrument for the house, take care that, to the juicer body was strong and held stably on the surface. Such components as augers, grater, mesh filters must be made of high quality stainless steel. This is the key to long-term operation of the device.
If you plan to process whole fruits and vegetables, pay attention to the dimensions of suction cups. If there is a bottleneck, you have to spend time cutting the fruit. In a wide pan device can simply add the washed products.
Centrifugal models are often equipped with various additional functions. Quite useful can be called a speed regulator, which allows the juices of different consistencies. Another necessary functions are: drop-stop system, protection against accidental activation, direct feed of the beverage, removal of the foam.
Now that you understand what they can have different types of juicers, you will be easier to choose the right device for you. Before going to the store, make a list of features you need to make it easier to choose.
