Abstract: A method and device are used for separating particles of plastic foil from organic material. The device includes a chamber with a perforated wall. A mixture of particles of plastic foil and organic material is fed into the chamber through a feed opening. The mixture is set into a rotating movement inside the chamber by a rotor. In the vicinity of the perforations, the centrifugal force to which a particle is subjected is at least fifty times greater than the gravitational force to which the particle is subjected. An airflow is generated in the chamber parallel to the rotational axis of the rotor. Particles of organic material leave the chamber through the perforations. Particles of plastic foil are carried along by the first airflow and then discharge through an opening in the chamber.

Abstract: A method for fractionating a milled grain product into coarse and fine fractions includes providing a sieving apparatus with a bottom chamber divided from a top chamber by a sieve, an inlet port in the top chamber, a top chamber cover defined by a plurality of openings, and a first exit port in the bottom chamber, and applying vacuum suction to the sieving apparatus. The vacuum suction is configured to draw grain particles through the inlet port into the top chamber, generate substantially horizontal airflow in the top chamber via the inlet port; and generate substantially vertical airflow in the top chamber via the plurality of openings, wherein the substantially horizontal airflow and the substantially vertical airflow combine to generate turbulence which fluidizes the grain particles in the upper chamber and prevents blockage of the sieve; and drawing fine grain particles through the sieve and out of the bottom chamber via the first exit port under the vacuum suction and collecting a fine grain particle fraction.
