Description

TECHNICAL FIELD The present invention relates to a rice milling machine, a rice milling facility, and an operation management system for the rice milling machine that can prevent variations in the quality of the rice grains obtained by polishing the same raw material unpolished rice.

The rice milling machine performs feedback control of the degree of pressure of the pressure lid, the number of revolutions of the polishing rolls, etc. while comparing the degree of whiteness and degree of polishing of the rice grains after polishing with reference values. A certain quality can be maintained.

By the way, in the above-mentioned rice milling machine, standard values such as whiteness and degree of polishing are set at the start of operation, and the operator inspects the quality of rice grains after polishing visually or with a hand-held whiteness meter. Products are produced after adjusting the whiteness and degree of polishing of rice grains after polishing, such as by changing the standard value above or below.

However, since there are individual differences in inspection by operator's visual observation and whiteness meter, for example, even if the production area, variety, and year of production are the same, if the operators are different, the rice grains obtained after polishing will not be polished. There is a problem that the quality varies to some extent.
