COMPARTMENT REPEATED-BATCH GRAIN DRYER WITH FLUIDIZED BED

摘要

FIELD: agricultural engineering. SUBSTANCE: heating up of ecologically pure air is carried out at its compression in high-pressure centrifugal compressor. New feature of the construction of grain dryer chamber is in mounting the upper cover with perforation, and in installing the perforated members in upper part of lateral walls of chamber in front of which regulated gate is set up. It shuts off air escape upward during grain pneumatic discharge. Reversible system guiding the regulated part of hot air to the input of compressor in the form of ejecting device is mounted in forcing air duct. EFFECT: simpler design, smaller dimensions and more mobility of grain dryer operating in ecologically pure air.
