Number of speeds
The number of speeds of the juicer. The optimal working speeds for different fruits are different: for example, soft fruits and vegetables need to be pressed at low speeds, solid ones (for example, carrots) — at maximum. In addition, the amount of pulp in the juice depends on the extraction speed: at high speeds it is more, at low speeds the juice is light.
The number of speeds provided by the design of the juicer can vary from 1 to 9. The more speeds, the easier it is to choose the optimal mode for each specific case.
Max. revolutions
The maximum rotation speed of the working tool is centrifuges in juicers, conical nozzles in citrus juicers. The higher the maximum speed, the more solid products can be processed in the device (this applies primarily to centrifugal juicers). At the same time, for soft products, a high rotation speed is not always suitable, as it leads to the ingress of an excessive amount of pulp into the juice. The perfect option is to have a speed control in the juicer (see Number of speeds).
Reverse
The ability to rotate the working tool of the juicer alternately in different directions. It is believed that this provides a better spin quality than during rotating in one direction; in addition, the
reverse can be useful in case of jamming of the nozzle. It is found mainly in models of auger design, as well as in devices for citrus fruits (see "Type").
Sorbet nozzle
A supplementary attachment specifically created for producing sorbet, which is a cold treat made from ice or frozen fruit and berry puree. It's important not to mistake sorbet for sherbet, which is a type of frozen dessert.
Nowadays, sorbet nozzles are mainly found in auger juicers (see "Type"), and are designed to grind frozen fruits and berries into a puree. Unlike traditional juicing, the pulp (cake) is not separated from the juice, resulting in almost the same amount of product output as input, but with a different consistency.
