Single Gear Masticating juicers are the preferable choice when looking for nutritious results from juicing fresh fruit and vegetables. They operate at very slow speeds and therefore retain the life force and live enzymes of the produce. They squeeze and chew the produce and are generally more efficient than centrifugal juicers which use blades spinning at very high revolutions per minute. Masticating juicers are also able to extract juice from leafy greens, herbs and wheatgrass.

Twin gear Masticating juicers are the most expensive types of juicer, which turn at even slower speeds than single gear juicers. They usually produce higher yields of juice.
