Are the Samson™® Gear Juicers centrifugal or masticating?
Neither. The difference is: Centrifugal uses a shredder disk/grater, which revolves at about 3600 RPM or faster and is usually very loud. (ACME and Omega) Masticating chews pulp to further break down the cell-wall structure. Then it mechanically squeezes. It uses a slow turning powerful motor that requires physical strength to use. (Champion) Gear Juicers are stone-mill types that work by the gear crushing produce into the walls (screen), which then extract juice. It is at low R.P.M and very quiet.
