Abstract

PROBLEM TO BE SOLVED: To embody the sure transfer from a grinding milling chamber to a friction milling chamber by forming a suction chamber above the inflow port formed by opening the upper part of a grain feeding chamber and connecting the suction chamber via suction pipe to a blower. SOLUTION: A finishing friction milling roll 15, lower feed grain feeding spirals 16, an initial grinding milling roll 30 and supply spirals 35 of a supplying cylinder 34 are respectively rotated by driving a main motor. When unpolished rice is supplied in this state into the supplying cylinder 34, the unpolished rice flows from an inflow port 33 into an ascending type initial grinding milling chamber 32. Since the multiflight spirals are formed in a milling cylinder 31, the unpolished rice is subjected to initial grinding and cleaning and is made to flow out of an inflow port 26 into the grain feeding chamber 25; thereafter, the polished rice is subjected to finish milling within the finishing friction milling chamber 18. During this time, the suction wind of a blower 22 is acted via the suction pipes 41, 38 in the upper suction chamber 40 of the inflow port 26 and, therefore, a negative pressure is generated therein. The foreign matter which cannot be sucked in the section chamber 37 is sucked as well, by which the movement of the grains from the initial grinding milling chamber 32 up to the inflow port 26 is smoothly effected.
