Description

Description: TECHNICAL FIELD The present invention relates to a polished rice discharging device of a rice polishing machine, which removes spotted fine powder adhering to the surface of polished rice grains to polish good quality polished rice.

[Prior art]

Conventionally, spotted fine powder adheres to the surface of white rice grains discharged from a rice polishing machine, and even if various improvements are made to the rice polishing machine, it is not possible to completely eliminate the fine powder, and it is possible to remove polished rice once. It is customary to supply it to a rice polishing machine to remove fine powder adhering to the surface of white rice grains.

However, when the white rice discharged from the rice polishing machine is temporarily stored in a storage tank and then supplied to the rice polishing machine for the rice polishing treatment, the effect of cooling and drying the white rice by the atmosphere is If the fine powder on the surface of the white rice grain adheres and the pressure exerted by the rice polishing machine is weak, it becomes difficult to remove the fine powder that has adhered to the surface of the white rice grain. The effect of was not born.

Therefore, low-temperature polished rice is mixed with bran for friction-grinding to improve the smoothness of the surface of the polished rice, then the bran is separated, and then wet-blast is applied to carry out friction-polishing to immediately generate the bran. A rice-polishing method of performing wet rice-polishing is proposed by the present applicant as Japanese Patent Application No. 61-160887. However, in this method of polishing rice, although polishing can be processed well, there is a problem that the operation and the device are complicated, and the fine powder adhering to the surface of the polished rice is efficiently processed. To this end, it is desirable to continuously install the rice polishing machine in the rice polishing machine before the white rice is cooled and dried.

By the way, the most commonly used polishing machine is the horizontal type, and the reason is that the polishing effect of the polished rice discharged from the polishing machine is confirmed or the pressing action of the polishing machine is performed. Although it has a great advantage that the device is easy because of the control device, the transmission device, etc., on the other hand, the polished rice that is subjected to the rotating action of the polishing rice trochanter horizontally installed in the polishing wall of the polishing machine is In the lower half of the rice, upstream induction is hindered by the self-weight of the white rice, the density of the white rice increases and the addition required for polishing is excessive, the whiteness of white rice progresses, new fine powder is generated, and porosity increases. In the upper half of the wall bran removal cylinder, the rotating force of the polished rice trochanter dilutes the density of the polished rice, and the effect of the diffusing collision of the polished rice with the porous wall bran removal tube causes the generation of broken rice or scratches. ,
It had a drawback that it could not be finished as a good-quality glossy white rice with uniform white rice grain surface.
