PRESSURE CONTROL DEVICE FOR CONTROLLING THE PRESSURE ON ROLLER BEARINGS IN MULTIROLL CHOCOLATE-REFINING MILLS

摘要

A system for controlling the pressure applied on the roll bearings of chocolate refining machines comprises, in addition to a linked multi-pressure control circuit, an additional circuit for applying linked single-pressure control, a selector valve enabling switching of one or the other of the operating modes. The dual-function system imparts refining machines with universal operation capabilities.
