As the name implies, this type of device is powered by centrifugal force. The used fruits and vegetables are crushed with a friction disc. At the same time, the container rotates around itself, which in some cases can reach speeds of up to 15,000 revolutions per minute. The resulting centrifugal force causes the juice to be “spun” from the fruit and vegetable pieces. This flows out through a spout while the pulp is led into another container.
High rotational speeds ensure that the fruit and vegetables are quickly pressed and that even large quantities can be processed quickly. That is why centrifuges are often used, especially in the catering industry. However, the high revolutions often develop heat. This allows valuable nutrients such as vitamins and enzymes to be removed from the juice. In addition, oxygen gets into the juice. This affects the quality of the ingredients and the taste. It also reduces shelf life.
Due to the high wattage and the large feed chute, you can juice hard fruits and vegetables such as beets, apples, or celery with a centrifugal juice extractor machine without much preparation or overloading the machine.
The advantages of a centrifugal juicer
- Due to the predominantly large filling shaft, you do not have to chop the ingredients or only lightly.
- The high speeds of up to 15,000 revolutions per minute make it possible to quickly make larger amounts of juice
- Both points mean less time is needed for pressing
Disadvantages of a centrifugal juicer
- The centrifugal force develops a lot of heat and higher oxidation. As a result, the juice sometimes loses considerably in quality. It has a lower nutrient content and is not as aromatic in taste.
- The oxidized ingredients ensure that the juices spoil faster, and you can not store them for a long time
- Centrifuges have problems with long-fiber ingredients such as wild herbs, grasses such as wheatgrass or barley grass, cabbage or celery
- Cleaning the equipment is more complicated, and the blades lose their sharpness faster
- A centrifugal juicer develops a relatively high noise level during use
