s. Juice is extracted by pressing or grinding a halved citrus along a juicer's ridged conical center and discarding the rind. Some reamers are stationary and require a user to press and turn the fruit, while others are electrical, automatically turning the ridged center when fruit is pressed upon.

Centrifugal juicers

A centrifugal juicer cuts up the fruit or vegetable with a flat cutting blade. It then spins the produce at a high speed to separate the juice from the pulp.

Triturating juicers

Triturating juicers (twin gear juicers) have twin augers to crush and press produce.

, is a larger scale press that is used in agricultural production. These presses can be stationary or mobile. A mobile press has the advantage that it can be moved from one orchard to another. The process is primarily used for apples and involves a stack of apple mash, wrapped in fine mesh cloth, which is then pressed under approx 40 tonnes. These machines are popular in Europe and have now been introduced to North America.

Steam juice extractor

A stovetop steam juice extractor is typically a pot to generate steam that is used to heat a batch of berries (or other fruit) in a perforated pot stacked on top of a juice collecting container that is above the steam pot. The juice is extracted without mechanical means so it is remarkably clear and because of the steam heating it is also
