ABSTRACT:
A drive assembly for presses for extracting cocoa butter from a cocoa paste comprises two three-piston pumps, of a constant flow-rate type, the motors of which are power supplied through corresponding frequency converters which are controlled by controlling systems programmed by electronic computers.
The pumps are so constructed and designed so as to facilitate conventional operations for replacing the gaskets of the pump pistons.
