Abstract

A cyclically operating filter press for squeezing juice from fruit is controlled so that the pressing pressure rises during an early part of a cycle and then, at a time determined in view of actual process variables, the pressure increase is stopped and the pressing pressure remains constant thereafter. The limiting time for the pressure rise is determined with a process.
