Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is used, for example, in combination with a hulling device to sort out a mixed rice of paddy grains and brown rice that is removed from the hulling device, and to take out brown rice from the mixed rice. This invention relates to improvements to rotating sorting barrel type separators.

The brown rice that has been sorted from the mixed rice is further sorted to remove small grains, and then shipped as carefully selected finished rice.This sorting process, which removes small grains, is conventionally performed in the same way as the above-mentioned process of sorting brown rice from mixed rice. This is done using a rice grader formed separately from the separator. For this reason, in the past, it was necessary to carry out a separate sorting operation in which the brown rice, which had been sorted from the mixed rice with a separator, was passed through a rice grader, which made the work process troublesome and caused the formation of layers. Rice grader and Nanano (later), Seno (later)
If the rice grader is combined so that the unpolished rice extracted from the come.

The purpose of the present invention is to solve these problems and to separate brown rice from mixed rice without increasing the length of the machine or complicating the drive. The next step is to construct a rotating sorting barrel type separator that can be taken out.
