US 7,171,893 B1 · Rotary press

Abstract

A rotary press is supported on a frame allowing liquid and solid receivers to be placed underneath the rotary press. The rotary press has an outer ring and an inner drum. The inner drum has an upper and lower flange with a stripper ring retained between these flanges. The flanges form two sides of the cavity where the pressing takes place. The flanges carry the solids away from the pressing zone to a discharge zone where the stripper ring expels the solids. By transporting the solids away from the pressing zone where liquids are expelled, reabsorption of the liquid is avoided. The stripper ring can move relative to the two flanges and is biased against the outer ring by the inner ring. The stripper ring applies pressure to the material to be processed and also pushes solid material from between the upper and lower flanges to fall into a receiver for the solids.
