Method and apparatus for the scoring of and the preparation for milling

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).

Separating contrivance for cereals

Apparatus and method for degerming maize are disclosed. The maize is introduced into a cylindrical, perforated working housing in which is mounted a rapidly rotating rotor which drives the maize along an annular working chamber between the rotor and housing. The rotor carries a large number of blades having edges which detach the germ from the endosperm. A collecting chamber surrounds the working housing, and the working housing is provided with an outlet aperture for oversize particles.

Degerming of maize

The invention relates to the dry cleaning of grain and discloses a new process and an apparatus. In the new process a deep layer of grain is formed on an upper screen, the holes of which are larger than the grain particles, and a compacting effect is produced in the bottom zone of the layer by vibratory forces. Sand particles sink into the layer compacting near the screen, and this layer drops completely--i.e. together with the sand particles--directly on to a second screen situated therebeneath. The sand passes through the bottom screen. The double screen is preferably preceded by a coarse screen. The apparatus is modular and comprises as separate modules a screen box, a head section containing the grain inlet and a tail section containing the outlets. A number of screen boxes of different sizes and head and tail sections of different sizes and arrangements may be provided to make it possible to supply a number of screening systems of different sizes. In the most advantageous construction, the head section and the tail section have adjustable or replacable flow guides to enable the product to be guided in different ways to and from the screens.
