摘要
Mixt. is placed in a housing and undergoes a kneading process using membranes. The membranes are first simultaneously and then alternating subjected to an external pressure, and the liq. which is pressed out is conducted away through an opening in the housing. The solid material remaining on completion of the pressing procedure is compressed by applying a vacuum to the membranes and rotating the housing, followed by a renewed simultaneous or alternating application of pressure. The membranes may alternatively be subjected to alternating pressure and vacuum so that the liq. is extracted without compressing the remaining solid material. USE/ADVANTAGE - For use in separating the phases of liquid-solid mixts. and esp. extracting fruit juice from the solid parts of the fruit. Complete recovery of the juice is achieved in a quantitatively and qualitatively optimal manner, and a continuous process is used in which ineffficiencies arising from the need to interrupt the process in order to agitate the pressed material are minimised. This is partic. advantageous in the case of the extn. of juice from grapes.
