<p>PROBLEM TO BE SOLVED: To provide a polished rice lead-out part of a rice milling machine capable of reliably separating contamination impurity such as chaff while guiding polished rice with a simple and compact constitution without requiring a troublesome adjustment operation.SOLUTION: A polished rice lead-out part 3 of a rice milling machine is constituted by disposing a discharge chute 3a for performing flowing-down guide of polished rice received from a polished rice outlet A on a milling part 1 front edge of the rice milling machine to the outside of the machine, a plurality of parallel protrusions 13... extended in a flowing-down direction are formed on a guide-way surface 12 of a discharge chute 3a, a groove between adjacent parallel protrusions of the plurality of parallel protrusions 13... is formed into a width dimension less than a grain particle size, a screening slit by means of a plurality of through-holes C... having a width dimension allowing the contamination impurity to fall on a bottom part of each groove is formed and, thereby, reliable and efficient separation of the contamination impurity is permitted by a simple and compact constitution.</p> |
