Abstract: The invention relates to a method and an apparatus for compacting flowable solids, in particular powders, flours or similar materials, preferably by packing in packagings or sacks. In order to increase the process reliability, there is provision for evacuation of the solid and its sack packaging to take place in a likewise evacuated environment.

Abstract: The new invention is directed to a continuous mixing and homogenizing plant, particularly for mill products. In so doing, the simultaneity of the mixing of all raw components in a pre-mixing space 8 is ensured in particular, so that subsequent continuous homogenization is also possible so as to meet the strictest demands. The utilized component weigher 4 and the assigned screw discharge 25 are constructed so as to be substantially tubular and together form a differential flow regulator 6. The inner surface of the entire system contacted by the product is accordingly tubular and is subjected to a continuous self-cleaning as a result of the movement of the product. Further, it is possible to arrange a plurality of component weighers 4 in a geometrically identical manner with respect to a collecting point 17 and a very high quality of mixing is obtained.

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 (15, 18). A uniform product feed is ensured by means of a cleaning device (13, 19) acting in two horizontal planes, wherein a relief base (15) with fall-through opening (16) 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.

Abstract: A method and an apparatus for the automatic filling of shipping bags with bulk materials with weighing accuracy. The pre-defined bulk material filling quantities are produced cyclically by controlling the discharge from a differential packer and weigher by determining the differential weight and are poured directly into the package via a flow filling sleeve. The pre-defined bulk material weight is directly packed as a dense stream on the shortest path via a flow filling sleeve. The majority of problems relating to weighing technology can be shifted to the area of the refilling of the differential weigher container with no disadvantageous results and no longer occur during the formation of the filling weight. The highest hourly outputs can be achieved particularly for packing carousels.

Abstract: A new device and method for measuring large production flows of e.g., one to fifty tons per hour with products such as mill products having unfavorable flow behavior. The production flow is directed intermittently into an upright weighing container for a brief time and is compulsorily discharged from the latter substantially horizontally so as to be controlled with respect to speed. The production flow is periodically monitored volumetrically and gravimetrically by means of differential weighing.The use of the method suggests that the production flow in a mill be measured by means of differential weighing for the purpose of controlling, e.g., monitoring the work process prior to wetting, e.g. as mill input capacity, e.g. for monitoring in the milling process, e.g. for the flour weigher.
