Abstract

The invention concerns a cleanable scraper station which is designed as a dispatch/receive station (1;1*) and through which the product or cleaning agent flows. The aim of the invention is to improve the cleanability of the scraper station compared with prior art devices, as measured by increased throughput, and in particular to ensure through cleaning of the entire scraper surface. This is achieved by virtue of the fact that the scraper (9) is positioned with play in all directions when in the through-flow position (II,II*) by means of a controllable second stop (6a;6a*) acting in conjunction with a displaceable first stop (5a,5a*) or by means of the controllable second stop (6a;6a*) acting in conjunction with a coupling cage (50;50*) connected to the displaceable first stop (5a;5a*) and in which the scraper (9) is positively locked, or only by means of the coupling cage (50;50*) connected to the displaceable first stop (5a;5*) and in which the scraper (9) is positively locked.
