SYSTEM AND METHOD FOR FRACTIONATING GRAIN

摘要

A sieving apparatus for fractionating a grain product comprises a top chamber separated from a bottom chamber by a sieve; a top chamber cover defined by a plurality of openings that allow substantially vertical entry of an air stream into the top chamber when the interior of the sieving apparatus is under vacuum via first exit port in a side wall of the bottom chamber for exit of air; an inlet port in a sidewall of the top chamber, the inlet port configured for feeding of dry grain particles into the top chamber and for substantially horizontal entry of air into the top chamber; and a first exit port in a sidewall of the bottom chamber for exit of air and exit of a first grain fraction from the bottom chamber when the interior of the sieving apparatus is under vacuum via the exit port.

1. A sieving apparatus for fractionating a grain product, the sieving apparatus comprising:
a. a top chamber separated from a bottom chamber by a sieve; b. a top chamber cover defined by a plurality of openings that allow substantially vertical entry of an air stream into the top chamber when the interior of the sieving apparatus is under vacuum via first exit port in a side wall of the bottom chamber for exit of air; c. an inlet port in a sidewall of the top chamber, the inlet port configured for feeding of dry grain particles into the top chamber and for substantially horizontal entry of air into the top chamber; and d. a first exit port in a sidewall of the bottom chamber for exit of air and exit of a first grain fraction from the bottom chamber when the interior of the sieving apparatus is under vacuum via the exit port.
