Abstract
Abstract A draining column consisting of an upright perforated sleeve with a supply for a whey-curd mixture at the top and a discharge device for the curd bar at the bottom. The upper portion of the sleeve is surrounded at some distance by a jacket. In the annular interspace a liquid is maintained at a specific level and under a controllable pressure to regulate the speed with which the whey leaks through the perforations of the sleeve.
