Manual screw juicer: features and how to choose

The manual screw juicer allows you to get natural healthy juice from any fruits and vegetables, as well as greens and nuts. To obtain juice, a little effort is required in comparison with electrical devices, but manual mechanisms are reliable and have a long service life.

Design features and principle of operation

Despite the fact that the market is full of juicers with electric motors, many housewives choose manual models. Screw type juicers are especially popular. It is believed that the juice obtained from the mechanical structure contains a greater amount of vitamins, since during the production process it is not amenable to heating.

If you are interested in what a screw juicer is, this design resembles a conventional manual meat grinder, familiar to all housewives. The basis of the operation of such a device is a spiral rod, which rotates when the handle of the juicer rotates.

The process of squeezing juice in such household "helpers" occurs in the following order:

1. Fruits or vegetables (most often prepared: peeled or cut into pieces) are sent to the inlet.
2. During rotation, the auger grinds the feed and propels it towards the filter.
3. Under pressure, the juice is separated and flows trickle into a glass or container.
4. The filter in the form of a metal mesh does not pass the cake. He goes to the side and is dumped through a special hole.

Despite the simplicity of the design, the screw juicer allows you to get up to 80-85% of the juice. This figure is many times higher when using centrifugal devices. Since the auger is rotated manually, it will take some effort to process fruits or vegetables into juice, especially for hard foods such as apples or carrots.

You can get juice using this device:

• from apples and other hard fruits;
• from plums, cherries, apricots and other soft fruits;
• from berries, including pitted berries;
• from root crops (carrots, beets, celery);
• from tomatoes and other vegetables;
• from parsley, dill and other herbs.

In this case, in order to obtain juice, it is necessary to strain the product obtained at the outlet through a sieve.

Advantages and disadvantages

Russian-made auger juicers do not lose their popularity, as they have many advantages. The main advantages of such devices include the following:

• mobility and non-volatility make it possible to use the device not only at home, but also in traveling conditions, as well as in places where there is no electricity;
• low price and availability in comparison with electric models;
• versatility makes it possible to process various fruits and vegetables into juices and mashed potatoes (some models have additional nozzles for a meat grinder and pasta, which extends the design functionality);
• the ability to operate for a long period without a break;
• high reliability of the design and long service life;
• silent operation allows you to squeeze the juice even in the early morning, without disturbing the household.

And although the list of benefits is impressive, screw type manual juicers have their drawbacks:

1. In manual models there is no engine, so the screw is rotated manually. This requires physical effort. For this reason, such designs are not suitable for processing large volumes.An alternative in this case could be an electric screw juicer, the main element of which rotates the engine.
2. The lack of an electric motor is reflected in the speed of juice production in comparison with electric models.
3. When processing soft fruits and berries, juice will be mashed instead of juice.
4. Before sending fruits or vegetables to the loading hole, they must be prepared: remove the seeds and peel, cut into slices and so on.

Types of manual screw juicers

The principle of operation of all screw juicers is the same, but depending on the design features and location of the screw, they are divided into the following types:

• single screw horizontal;
• single screw vertical;
• twin screw horizontal.

Each species has its own characteristics, advantages and disadvantages.

Single screw horizontal

In this type of juicer, the screw is located horizontally. The main advantage of such devices is multifunctionality. If you have the necessary nozzles, you can use them:

• for the preparation of juices and mashed potatoes;
• for the preparation of mousses and pastes;
• for grinding meat and other products;
• for making pasta;
• for making homemade sausages or sausages and so on.

The minus is a small inlet, so apples, pears and root crops will have to be cut into pieces beforehand.

Single screw vertical

A vertically arranged auger allows you to cope with the processing of almost any fruit and vegetables. A large loading hole allows you to speed up the process of squeezing the juice, reducing the preparatory stage. Vertical juicers are not very suitable for squeezing juice from herbs.

Twin screw horizontal

Models with a twin auger have more performance. They allow you to get up to 95% of the juice due to stronger grinding and pressure. For processing, you can use any "raw material" - from apples and carrots to grapes and herbs.

Among the shortcomings, it is worth noting a more complex care. Washing the device is complicated by a large number of parts, although disassembly and assembly does not differ from single-screw models and also does not cause difficulties.

Features of choice

Manual juicers of domestic and foreign manufacturers are presented on the market in a wide assortment, which often complicates the choice for consumers. If you decide to purchase a screw mechanical juice extractor, but don’t know how to choose a suitable model, pay attention to the following points and characteristics:

• size and weight. A compact device will be used more often, but bulky models are more likely to gather dust on a shelf;
• screw material. Give preference to cast iron and steel stainless elements, as they are characterized by high strength and reliability, but are not inferior to plastic screws for hygiene;
• volume and diameter of the feed opening. The smaller the loading hole, the more vegetables and fruits will have to be cut before processing;
• device type. Vertical juicers are not suitable for obtaining juice from herbs, while horizontal juicers have a small loading hole, twin-screw ones are more difficult to care for and cost more;
• metal filter. Pay attention not only to the diameter of the holes in the filter, but also to the material from which it is made (stainless steel is an excellent option). The finer the filter mesh, the less pulp in the juice, but the more likely it will clog;
• receiver. The ability to twist the screw in the opposite direction eliminates the need to disassemble the device if it becomes clogged.

If you are wondering where to buy a manual screw type juicer, you can do this in online stores, ordinary stores, and markets. When choosing a device, pay attention to the material from which it is made, since the safety of squeezed juices depends on this.
