Abstract: A method of treating and processing alkaloid, oil and protein-containing lupine seeds for the extraction of products from the lupine seeds by means of targeted fractionation is described, whereby the comminuted lupine seed is de-oiled by introducing a solvent and the residue is depleted of substances soluble in the acid range, preferably of alkaloids, by adding acids. The invention is characterized by the provisions that the lupine seeds are comminuted and/or shaped to form discoid flakes in such a way that after pre-crushing of the shelled or non-shelled seed containing the plant seeds the comminution of the plant seeds is carried out by means of a cooled flocculating roller, and the seed is heated by indirect supply of heat, largely with exclusion of water, and that after de-oiling the depletion of the flakes of substances soluble in the acid range, preferably of alkaloids, is performed by aqueous extraction, with a refined product of reduced alkaloid level and an aqueous extract being obtained.

Abstract: The present invention relates to a method of separating a machining suspension into fractions including abrasive grains and attrition material, such as a suspension produced in the course of the mechanical machining of silicon, quartz or ceramic material, from a cutting fluid in which abrasive grains and the attrition material are dispersed that originates from the machined material and from the machining equipment. In the method, the suspension is separated by means of wet classification, with the liquid used for the sizing process being selected in such a way that it can be mixed with the used cutting fluid and with the mixture so formed, which contains the attrition material originating from the machined material in particular, forming a stable suspension.

Abstract: A method treating and processing alkaloid-, oil- and protein-containing lupine seeds for the production of lupine seed products by selective fractioning. The invention involves the steps of crushing and/or shaping the lupine seeds to form platelet-shaped flakes, indirect introduction of heat into the platelet-shaped flakes, with water being largely excluded, to deactivate enzymes contained in the lupine seeds, de-oiling of the platelet-shaped flakes by introduction of a solvent for obtaining lipids and lipid-reduced flakes, disembitterment of the lipid-reduced flakes by an aqueous disembitterment process for obtaining an alkaloid-reduced refined product and an aqueous extract.
