Description

Detailed Description of the Invention (Industrial Application Field) The present invention is a friction type rice milling machine that processes milled rice grains into polished rice with a predetermined sprouting rate by measuring the sprouting rate of polished rice grains. Concerning the automatic control device for de-sprouting rate.

[Conventional technology]

If a large number of ungerminated rice grains are mixed into the polished rice grains, the rice will smell and lose its flavor during cooking, resulting in a significant decrease in the product value. Therefore, it is necessary to prepare the rice milling machine while constantly measuring the occurrence of undetermined rice grains.

Conventionally, to measure the de-sprouting rate during rice milling, 81 rice grains were randomly extracted from the rice milling machine, and the de-sprouted rice grains and un-de-sprouted rice grains were manually sorted. The sprouting rate was calculated.

However, conventional methods of measuring the de-sprouting rate are done manually, which is very time-consuming and inaccurate. Therefore, even if the -C rice milling machine was adjusted based on the determined de-sprouting rate, a considerable amount of time had passed from the time of measurement, and there was a problem in that the de-sprouting rate could not be adjusted accurately.

In addition, rice grains are difficult to de-sprout depending on the variety. Furthermore, it is difficult to produce buds of the same variety in cold regions like Hokkaido. Therefore, if the variety or production area changes, the germination rate will change, and the pressure in the whitening room must be adjusted each time, which is a hassle.

One end of the polishing chamber where the cylinder and friction polishing trochanter are located is the rice grain supply section, and the other end is the resistance plate.
