A juicer is a tool for separating juice from fruits, herbs, leafy greens and other types of vegetables from its pulp in a process called juicing. In separating the pulp, juicers concentrate the nutrition naturally present in fruits and vegetables which allows the body to more easily absorb the nutrition than digesting the solid produce. The use of juicers also makes it easier to consume more raw produce. Some juicers of the masticating or twin gear variety perform extra functions too, such as crushing herbs and spices, and extruding pasta.
Reamers are used for squeezing juice from citrus such as grapefruits, lemons, limes, and oranges. 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.
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 or Twin Gear Juicers
Triturating juicers have twin augers to crush and press produce.
A juicing press (Fruit press, Wine press) is a larger scale press that can be stationary but also mobile. A mobile press has the advantage that it can travel to a farmers apple orchard and press juice right then and there. 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 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 becuse of the steam heating it is also pasteurised ready for long term storage.
