What is a screw juicer

The lack of various vitamins and minerals and the crazy, exhausting rhythm of the body is a common occurrence for a modern person of 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 herbs. Any household appliance undergoes continuous improvement, updating, which helps to increase 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. Which ones - find out below.

What is a screw juicer

The main principle of the screw apparatus is to produce juice using cold pressing. It is in the absence of warm air that the secret to obtaining juice that is more saturated with vitamins lies in the heat - it oxidizes in heat and useful elements simply disappear. On this, the advantages of a screw juicer do not end, but only start:

• the technology has increased productivity and versatility, which will allow you to work with complex and solid products, such as seeds, nuts, greens;
• the work is almost silent;
• the speed of such an apparatus is almost double that of a centrifugal type;
• very easy care - just a glass of water inside and starting work.

Judging by the name, the principle of operation of this juicer is the presence of a screw. 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 is applied by means of a press, the juice is filtered through special membranes, the finished, filtered juice is separated into a juice collector, and the cake is pressed into a bowl.

Given that the juice production process takes place practically using natural pressure and grinding, there are no actions in the device that can heat the air. Warm air oxidizes some products and often, using centrifugal models, acid juices could be obtained. 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 and horizontal. In addition to appearance, they are distinguished by additional elements, efficiency and convenience:

1. Horizontal models will produce juice if the products are pushed by special pushers. This procedure slightly increases the time required to produce juice, which can be a disadvantage. But a clear advantage of these models is the best production of juice from herbs or herbs, as well as work with solid products - nuts, vegetables, seeds, berries with seeds.
2. Vertical screw type juicers are able to independently capture and process incoming products, they do not need pushers. Such models are more compact and productive.

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

In addition to design features, juicers can differ in the number of screws themselves - they can be one or two.

The difference between a screw juicer and a centrifugal

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

• price - a centrifugal model will be guaranteed cheaper than a screw;
• the versatility of working with any products, including solid ones, differs only in a juicer with a screw - centrifugal can not cope with solid products;
• the quality of the finished juice is better with screw machines, due to the lack of warm air and the process of juice oxidation;
• the consumption of initial products in centrifugal models is very high, but when working with the screw, it will be possible to get 45-85% more juice from the same amount of loaded ingredients;
• juice squeezed in a screw juicer can be stored for up to 48 hours, but from a centrifugal model the juice has already been exposed to oxygen and heat, and has a low shelf life;
• when the screw is working in the juice, the appearance of pulp is permissible, but not everyone likes it - centrifugal models will leave all the pulp in their own centrifuge;
• the sound distribution during the operation of a centrifugal juicer is very high, and the screw models are much quieter.

In general, even minor inconveniences of the machines with screws can be easily translated into convenience. For example, the pulp produced during the production of juice may be desirable for children, and if you grind soft and ripe fruits, you can get excellent mashed potatoes.

What criteria should be considered when choosing a juicer

In order to purchase a juicer, which will perform all the required work and give out the product of the desired quality and consistency, you need to decide in advance on the purpose of its acquisition. The more compact sizes differ in vertical versions of screw models, and in the kitchen, most often, there is little space for storing overall items of household appliances. If the goal is to obtain unusual juices from unusual ingredients - nuts, herbs, herbs - a horizontal model is suitable. There are other parameters that you must pay attention to:

1. Case material - is plastic or metal. Modern plastic is durable, safe, easy to clean. But if the model uses white plastic, it will quickly turn into the color of fruits or vegetables. Steel options will be heavier, but generally more durable.
2. The material of the screw itself can be plastic, aluminum, cast iron or steel. Plastic augers are new, and help in getting rid of the steel aftertaste.
3. The membrane material and its size can be made of steel or plastic. Steel membranes do not react at all to fruit acids, but if the juicer is designed for one type of fruit, you can do it with a plastic net. The size of the holes will directly affect the texture of the juice and the presence of pulp in it.
4. Hole for laying products - it is better to choose those models in which this hole has a larger diameter. Then you don’t have to cut some products, and you can lay more at a time.
5. Modes of operation - they can be from 2 to 9. In order to get a universal model, it is better to stop at a variety of modes.
6. Reverse mode - not every model is equipped with it, but this indicator can seriously help in cleaning the screw. When the reverse mode is on, the screw starts spinning in the opposite direction, getting rid of jammed pieces of food.
7. Power - this indicator affects the speed of getting a finished glass of juice. The average power indicators of most models are 200 watts, this will allow you to get a whole glass of juice in just a couple of minutes. For domestic purposes, such characteristics are quite satisfactory.

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

When choosing a suitable 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 possible that adhering to the principles of proper and wholesome 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 a 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 possibilities.
