PCT No. PCT/CH95/00033 Sec. 371 Date Oct. 18, 1995 Sec. 102(e) Date Oct. 18, 1995 PCT Filed Feb. 15, 1995 PCT Pub. No. WO95/22453 PCT Pub. Date Aug. 24, 1995A 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.
