More about the twin gears
The twin gears are unique to the juicing world. They are precisely what they claim to be – gears. Not blades, augers or rotors. The twin gears mesh together at a clearance of a mere 4/1000 of an inch to gently crush, squeeze and grind the juice from the produce, much like your teeth do.
Those “cut out”places along the length of the gears serve different purposes. The recessed area along the gear length more easily accepts fibrous vegetables and herbs like carrots or stinging nettle. The actual “cut out”places are fantastic for cutting the stringy fibers found in celery and other long-fibered herbs. Those “cut out” places are what allows you to put a full-length stalk of celery into the Hippocrates without jamming or clogging.
The twin gears are gears – NOT blades. Because they are not blades, they are not sharp. They work in a totally different way. With proper use and care, the twin gears should last many years with no maintenance.
