Twin gears are the juicing pinnacle they often cost the most of course but offer the most precise juicing and the best yield. Twin gear juicers work by using two counter rotating gears that roll together compressing the juicing material allowing the juice to run between the gears. A profiled front section to the gears pushes the waste pulp along and out of the front of the juicer. If a measure of a juicer is the dryness of the pulp, then the twin gears are the most efficient juice extractors.

Twin gear juicers juice the fine leaves of wheatgrass particularly well offering the best yield from this costly crop. Twin gears are particularly good at extracting wheatgrass juice as the leaf is highly fibrous and tough, needing the high compression and precision that the twin gear offers.

One disadvantage to twin gear juicers is that they can struggle to grip and juice softer fruits, this disadvantage is lessened by juicer gear diameter, so check which juicer has the largest gear size before you buy. At the time of writing this is the Easyhealth Angel twin gear. If you want to juice soft fruits then a single auger juicer is better. Or just use a strong blender.

Speed of rotation is important when evaluating a new juicer as the higher the speed, the more likely oxidation will take place. Most twin gear juicers rotate between 80 and 135 rpm, which is excellent for preserving juice quality and nutritional benefits of the juice.

One aspect to owning a twin gear juicer cannot be ignored; the juicer itself is quite complicated with many intricate working parts this makes for an involved clean up, so make sure you are aware of this before you buy.

Twin gear juicers offer the greatest efficiency of all the types of juicer. Twin gears are also the most costly and complicated, worth the effort and expense but make sure you are a committed juicer.
