Masticating juicers work much differently than centrifugal juicers. It takes quite a long time to produce juice using a masticating juicer. This long process, combined with the high price of masticating juicers, has made them less popular than centrifugal juicers. Still, this type of juicer yields much more juice per fruit or vegetable than a centrifugal juicer, and breaks down leafy greens with much less effort.
Available with one gear or two, these machines literally grind small pieces of fruits and vegetables to release juice and tiny bits of fiber small enough to escape pulp collectors.
Some people prefer this type of juicer not only because it yields more juice, but also because the juice produced is believed to be of higher quality. The slow process by which this type of juicer creates juices is designed to maintain the cool temperatures that protect important enzymes that may be killed off in the centrifugal juicing process.
