Abstract:
1. A device for separating the various sorts of particles in a mixture comprised of particles produced by comminuting the grains of cereal grains, in particular wheat, and are present as a mixture consisting of at least a first and second sort of particle, comprising: a) a first impact area with at least one surface of at least one solid material, along which the particles of the first particle sort and the second particle sort of the mixture can move in such a way that at least one portion of their particle surface is at least sectionally in contact with the solid material surface as they move along the at least one solid material surface; and b) a second impact area subsequent to the first impact area, with a first electrode area and a second electrode area, between which an electrical voltage can be applied; and with a first accumulation area for particles of the first sort and an accumulation area for particles of the second sort separate from the first accumulation area, wherein the at least one surface of the at least one solid material is concave in the first impact area, so that the particles of the first sort and second sort that can move along the concave surface are pressed against the concave surface of the solid material as a result of their centrifugal force as they move inside the first impact area; wherein the first impact area has a curved channel with a first end and a second end, in which a product inlet and fluid inlet is connected to the first end, and a product separator with a product outlet and fluid outlet is secured to the second end for separating the product and fluid, wherein the mixture having particles of the first sort and particles of the second sort can be supplied through the product inlet, carried by a fluid stream supplied through the fluid inlet and discharged through the fluid outlet through the first impact area with the curved channel and along its concave surface, and finally routed through the product separator and its product outlet into the second impact area with the particles in their respective electrically charged state.
