Problems solved by technology

Therefore, even if the short-grained brown rice of China, Korea, and Taiwan is finely ground with a rice grinder adjusted in the above-mentioned manner, there are many defectives, so a large amount of broken rice is produced, and the yield rate is greatly reduced.

Embodiment 1

[0051] The refining test was carried out with the brown rice of short-grain varieties produced in China.

[0052] As the raw material variety, "Kongyu 9031" of the "Kongyu 131" series, a Japanese short-grain seed produced in 2009, was used. Whiteness is used as a reference for fineness. The whiteness was measured by the brown rice and polished rice whiteness meter C-300 manufactured by KETT Scientific Research Institute of Japan.

[0053] Initially, the refining test was carried out with a triple-tandem refining apparatus equipped with standard stirring rolls and a rice-grinding wire mesh, which did not have the features of the present invention. The results are shown in Table 1 below.

[0057] Next, a refinement test was carried out by using the elongated resistance body 37, the resistance rod 69, and the stirring rod 57a of the present invention, and the adjustment of the gap was completed by the three-series re...

Embodiment 2

[0070] The refining test was carried out with brown rice of short-grain varieties produced in Korea.

[0071] As the raw material variety, "No. 5", a short-grain variety close to Japan produced in 2009, was used. The mixing rate of cracked grains of raw brown rice was 22%, and the mixing rate of immature grains was 10%. As a benchmark for fineness, whiteness is used. The whiteness was measured by a brown rice / milled rice whiteness meter C-300 manufactured by KETT Scientific Research Institute of Japan.

[0072] Initially, refining tests were conducted with a triple-tandem refining apparatus equipped with standard stirring rolls and a rice-grinding wire mesh, which did not have the features of the present invention. The results are shown in Table 4 below.

Abstract

The present invention provides a polishing device for low-grade brown rice capable of reducing the occurrence of broken rice even when it is foreign-grown low-grade brown rice containing a large amount of defectives such as immature rice and cracked rice. In the present invention, the support of the grinding-type bran-removing metal mesh cylinder of the aforementioned vertical grinding-type rice grinder is provided to protrude toward the aforementioned fine-grinding chamber, and the grinding-type polishing roller is rotated to the circumferential direction to achieve The strip-shaped resistance body that provides resistance to the movement of grains is provided with a plurality of resistance rods at its inner corners on the friction-type bran-removing metal mesh cylinder of the aforementioned vertical friction-type rice grinder. The longitudinal direction of the friction stirring roller of the rice mill is equipped with the elongated stirring rod which overlaps with the said several resistance rods and provides resistance to the movement of grain by the rotation of the said friction stirring roller to the circumferential direction.

Description

technical field [0001] The present invention relates to low-grade unpolished rice that can reduce the generation of broken rice even in raw unpolished rice of poor quality, such as unripe rice mixed with a large amount of immature rice and unripe rice mixed with a large amount of cracked rice. A method for grinding brown rice and its device. Background technique [0002] When operating a rice grinder installed in a rice polishing factory, etc., the operator confirms in advance the characteristics of brown rice (moisture content, variety, production area, preparation method after harvest, etc.) Adjust the movement of the resistance body in the fine grinding chamber to start fine grinding. This is because by setting the optimum polishing conditions for the rice grinder according to the characteristics of brown rice, it is possible to contribute to a marked improvement in the degree of polishing and the yield. However, such manual movement adjustment of the resistance body of...
