Abstract
The new invention is directed to a metering device (1) which can be constructed as a differential weigher. The product is stored in a weighing container (2) which is possibly cylindrical and comprises a flat base (16, 18). A uniform product feed is ensured by means of a cleaning device (13, 19) acting in two horizontal planes, wherein a relief base (16) with fall-through opening (15) is preferably arranged between the two planes in such a way that a pre-metering space (17) is formed in the lower part of the weighing container. The product is conveyed out of the pre-metering space (17) through the lower cleaning device (19) to the metering screw (4) and discharged in a metered manner by the latter by means of controllable speed.
