Vertical type grain-milling machine

摘要

A vertical type grain-milling machine has a perforated bran removing cylinder arranged vertically with respect to a machine frame; a main shaft which is rotatably provided within the perforated bran removing cylinder; and a milling roll and a screw roll which are in abutment with each other and which are mounted on the main shaft, the milling roll being associated with a grain discharging section and the screw roll being associated with a grain supplying section. The perforated bran removing cylinder is surrounded by an air in-take frame which has a large number of through-holes for causing in-flowing air to have a downward component of orientation. The discharging of the bran externally of the machine is enhanced and the adherence of bran onto the inner wall of the air in-take frame and the perforated bran removing cylinder is prevented.
