Abstract
A separating contrivance for separating cereals and similar grain product into at least three grain fractions and heavier impurities comprises two air-penetrable fluidized bed tables (2, 3) arranged one over the other and supported in fashion capable of being oscillated in relation to a frame, with a product inlet (9) leading to the upper fluidized bed table. At one end of the contrivance, and spaced away from the inlet (9), the upper fluidized bed table (2) is provided with outlets (10, 18) for the light and medium heavy grain fractions, while the lower fluidized bed table (3) includes outlet (27) for the heavy grain fraction. Adjoining the other end of the lower fluidized bed table (3) is an outlet (16) for the heavy impurities such as stones and the like. In order to achieve a practically complete sorting of the heavy impurities, provision is made so that the two fluidized bed tables (2, 3) are supported independently of one another and are driven by separate oscillating drives (7, 25).
