Leak-resistant feeding chamber for chocolate refining machines

摘要

A lateral end upright for the feeding roll pair in chocolate refining machines is formed by two half-uprights in mutual abutment relationship and individually mounted to one of the feeding rolls. The abutment sides of the half-uprights have a thickness dimension which is selected to ensure continuity thereof even with the feeding roll axles tilted to their full oscillated positions. A flexible insert may be interposed to the upright halves. Offsetting play due to wear can be taken up, as can differences in the working lengths of the feeding rolls.
