Abstract: A material bed roller mill for comminution of grain in a material bed. The material bed roller mill comprises rollers, at least one feed opening, a draw-in region between the rollers, a grinding gap between the rollers and at least one delivery opening. The material bed roller is configured, during operation, to produce a material bed in the draw-in region and to draw grain from a surplus thereof by a filled material duct or hopper. A specific grinding force of the material bed roller mill can be set in such a way that grain is heated, during the grinding operation, by less than 30° C., preferably by less than 15° C., to the temperature of the grain before the respective grinding.

Abstract: A grinding arrangement for producing flour from cereal grain has at least one grinding mechanism designed as a stock-bed roller mill. The grinding mechanism has at least one feed opening and at least one dispensing opening. The grinding arrangement has at least one separating stage for separating ground products into finer ground product and coarser ground product, and returns at least some of the coarser ground product into the feed opening of the grinding mechanism.

Abstract: The invention relates to a method for the preparation of aleurone from bran, in particular, wheat bran, for the extraction of aleuronic cells in particular from wheat grain, whereby the mainly aleurone-containing aleuronic components are separated from the mainly non-aleurone-containing non-aleuronic components in the bran and the aleurone-containing components are then isolated. The separation can be achieved by biochemical/enzymatic means and/or by mechanical-abrasive means. The subsequent isolation and extraction can be achieved by wet and/or dry separating methods.

Abstract: The apparatus according to the invention relates to a grinding arrangement (1) for producing flour from cereal, the latter in particular being bread wheat, durum wheat, maize or buck wheat. The grinding arrangement is characterized by at least one grinding mechanism (2) which is designed in particular as a stock-bed roller mill (16). The grinding mechanism has at least one feed opening (3) and at least one dispensing opening (4). The grinding arrangement comprises at least one separating stage (5) for separating ground products into finer ground product and coarser ground product, and a return arrangement (8) for returning at least some of the coarser ground product into the feed opening of the grinding mechanism.

Abstract: The invention relates to a method and device for separating a mixture made of particles of a first particle type and a second particle type, especially aleurone particles and shell particles made of comminuted bran, said particles being scarcely distinguishable in terms of size and density, into various types of particles. Separation occurs according to particle-type specific triboelectric charging of said particles in a first active area and subsequent separation of the differently charged moving particles in an electric field.

Abstract: This invention is directed to a composition comprising at least one aleurone component and aleurone, extracted from bran and effective substances contained in the aleurone and their favourable physiological properties are supplied to a human or animal in an easily accessible form, as well as a method of manufacturing thereof. This composition can be administered to a human or animinal. The composition of the present invention can be manufactured by adding the aleurone component and/or the aleurone to a food component or fodder component in a liquid or powder form which is easily accessible to the human or animal organism.

Abstract: Process and apparatus for reducing the size of particles of a flowable material. The process includes a stream of the fluid and the particles that is fed under pressure. The particles are subjected to expansion forces in a first dimension while they are simultaneously fed through at least one continuously narrowing constriction. While the particles in the fluid are conveyed through the narrowing constriction, they are subjected also to expansion forces in a second dimension. The apparatus may include a device which pressurizes the fluid and its particles which are fed through at least one inlet into a space. This space is defined from two sides only by at least one pair of opposing walls. Thus, the walls form a narrowing constriction up to a gap of smallest cross-section. This gap communicates with the outlet.
