This is a Norwalk Juicer model 270 which was bought as part of a Gerson cancer treatment that involves juicing. It is a cold presser juicer which means it retains about 70% of the enzymes as the vegetables or fruits are not exposed to heat, which tends to destroy the enzymes. An ordinary juicer retains approximately 45% of enzymes after being exposed to heat from a centrifuge. The plunger is made of wood and I have had to shave off a few layers because the wood expanded after being exposed to water whilst cleaning it. Hence its uneven looking surface. Nevertheless, works fine. This item weights approximately 66 pounds and is for pick up only in Armadale, Victoria. If you should have any questions please feel free to contact Gitte on 0419 350 656.
