Patent DE-2917544-A1 (DE)
Title: Control system for hydraulic press for degreasing cocoa mass - regulates pump delivery according to load and stroke ratio
Inventor: KEGEL WALTER
IPC: B30B9/04
Filed: 1979-04-30
Abstract: The fat is pressed out a mass of cocoa in a hydraulic, multichamber press. The press piston is loaded for the transfer of the pressure to the material by a pump with a number of plungers. By means of these, when a predetermined pressure has been rached, the flow of hydraulic fluid is reduced automatically by the opening of the suction valves in the pump block. The hydraulic pressure exerted by the pump and the amount of stroke of the press piston, or the weight of the cocoa butter pressed out, are converted into equivalent electric values of the same kind. From them, differential value is derived from which the behaviour of the mass of cocoa under pressure can be evaluated, and by which the delivery of the pump is regulated automatically. System increases the output of multichamber presses and expels the maximal amount of butter from the mass without increasing energy requirements. At the same time the risk to the operative of being sprayed with hot grease is reduced. The system ensures the maximal speed of the press dependent upon the characteristics of the mass in the pressing.
