Juicers: specifications, types

— Citrus juicers operate through a special rotating nozzle with a conical shape with a ribbed surface. In order to extract juice using this type of nozzle, the user must place a halved fruit with the pulp side down and apply pressure using either their hand or a provided clamping mechanism (see Pressing mechanism). The juice is then extracted through the grate-filter and collected in a bowl below, while the peel remains intact. Some models may also have a reverse...mode (see Reverse) to optimize the juicing process. Typically, citrus juicers have lower power and capacity compared to other types of juicers.

— Centrifugal, or universal juicers allow you to get juice from almost any fruit, berry or vegetable. The process in centrifugal juicers starts with grinding the produce into a uniform mixture using a grater, which is then directed to the separator. The separator applies centrifugal force to the mixture, causing it to press against a filter, separating the juice from the pulp or cake.

— Screw. Auger juicers use a rotating cylinder with spiral ribs, which is the primary mechanism for extracting juice, similar to meat grinders. They are versatile and can extract juice from almost any fruit, berry, and vegetable. Because of their low speed of rotation, they consume less energy compared to centrifugal juicers. Some manufacturers claim that auger juicers separate juice from the cake more efficiently, resulting in drier cake and more homogeneous juice. Despite this, they are typically more expensive than centrifugal juicers.

— Combined juicers combine elements of a citrus and centrifugal/auger juicer and allow you to get juice from both citrus fruits and other fruits and berries. However, it is believed that such juicers work less efficiently than specialized devices.

The form factor is the determining parameter for using a screw juicer for certain needs. This category of devices is distinguished by the location of the executive body.

— Vertical. Juicers with a vertical auger are designed to automatically capture pieces of fruit, vegetables, and berries under their own weight. The screw mechanism then gently squeezes the juice, and these devices occupy less space on the kitchen table. Another advantage of the verti...cal form factor models is their faster juicing speed.

— Horizontal. Juicers with a horizontal auger have a similar design to meat grinders. The process of extracting juice involves crushing the products using a rotating shaft, pushing them forward to the filter, and then allowing the juice to flow out of one opening while the cake is removed through the other. Although horizontal models may not be ideal for delicate products, they are effective in preparing purees, ice cream, and fresh pulp. However, to use a horizontal auger juicer, fruits and vegetables must be manually pushed into the loading mouth using a pusher.

The volume of the built-in or freestanding juice tank (see Juice capacity). It is usually in the range from 0.2 to 2 liters. Doing more volumes, usually, does not make sense — freshly squeezed juice is considered the most useful, and it quickly loses its properties. Therefore, the best option is to prepare small portions of juice up to 1 liter, with the expectation that you can drink it right away. On the other hand, for the preparation of canned juices, ..."/list/101/pr-1201/">a tank volume of 1.5 – 2 liters is usually quite enough.

The volume of the tank for the oil cake (pressed pulp) installed in the juicer.

While most models with a pulp tank come equipped with an automatic pulp ejection function (see "Functions"), there are some exceptions. Nevertheless, the size of the tank directly affects the duration for which the juicer can be used without having to empty the oil cake residue. However, an increase in capacity significantly impacts the device's dimensions, weight, and cost.

Modern juicers...are designed with oil cake containers ranging from 200-500 mL in the most compact models to 3 liters or more in larger ones. The specific capacity is usually chosen by designers based on the unit's total power and performance. However, models with similar performance characteristics may differ in their oil cake container volume. When selecting a juicer, it's important to consider the intended use of the device. For occasional home use, a smaller container may suffice, but for a cafe or bar where freshly squeezed juices are prepared regularly, a larger capacity juicer may be the better option.

The power of the juicer depends on its type. For example, the power of citrus juicers rarely exceeds 40 W, since the structure of citrus fruits is easily destroyed and does not require serious effort to extract juice. The power of centrifugal juicers can even exceed 1000 W. The centrifugal speed and spin features depend on the power of the centrifugal juicer (for more details, see Number of speeds)

Modern juicers can be equipped with both built-in and free- standing juice containers. In the latter case, you can use any other suitable height: a glass, a jar, etc. instead of the container supplied with the device.
