GRAIN CLEANER DUAL ASPIRATION OPEN-AIR SYSTEM WITH SECTION BLOWER

摘要

FIELD: process engineering. ^ SUBSTANCE: invention relates to grain cleaning equipment and may be used in agriculture, flour-milling and feeder industries. Proposed system comprises two air separation channels with air openings arranged above separation zone provided with their drives, two settling chambers with separation web, cross-flow fan with controlled rpm, air intake openings and air discharge channels, device to feed grain heaps and to discharge produced fractions. Working wheel and inlet opening of cross-flow fan are divided into sections to allow independent and separate air intake from grain cleaner settling chambers. ^ EFFECT: higher efficiency of cleaning. ^ 4 dwg
