A brown rice processing device and processing method

Abstract

The present invention relates to a brown rice processing device. A plurality of carrying boxes are arranged on a circular conveyor belt, brown rice is placed in the carrying boxes, and the brown rice is blown to suspend in the peeling device by air flow for friction peeling, and the peeling motor is controlled by the control device. When the conveyor belt is transported to the top of the carrying box, the peeled bran and polished rice will come out of the box, and the unpeeled brown rice will be peeled again when it is transported to the top, which realizes cyclic peeling and separation, preventing Unpeeled brown rice and polished rice cannot be separated, and intermittent peeling makes it easy to separate the polished rice and bran, which enhances the efficiency of brown rice peeling.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a brown rice processing device and processing method. Background technique [0002] The three-phase mixture of the underhull, after separation and removal of the rice bran and leaking rice, the rest is rice grains, but the rice grains at this time are rough, traditionally called brown rice, brown rice is used for cooking, and the cooking time is long , dark color, poor viscosity, and bad taste; and because the cortex of brown rice is complete, water absorption and swelling are not strong, resulting in poor eating quality; Digestion; these unfavorable factors make people actively take off the coat of brown rice. This process is called rice milling process. Rice milling generally has chemical and mechanical methods. In chemical method, solvent extraction is generally used to mill rice, starting from the softening of rice bran oil. The cortex of brown rice is lightly milled...

[0002] The three-phase mixture of the underhull, after separation and removal of the rice bran and leaking rice, the rest is rice grains, but the rice grains at this time are rough, traditionally called brown rice, brown rice is used for cooking, and the cooking time is long , dark color, poor viscosity, and bad taste; and because the cortex of brown rice is complete, water absorption and swelling are not strong, resulting in poor eating quality; Digestion; these unfavorable factors make people actively take off the coat of brown rice. This process is called rice milling process. Rice milling generally has chemical and mechanical methods. In chemical method, solvent extraction is generally used to mill rice, starting from the softening of rice bran oil. The cortex of brown rice is lightly milled. During the milling process, rice bran oil and n-hexane are continuously sprayed to form drizzle to moisten and finally obtain undamaged low-temperature white rice. The mechanical rice milling method is to use special equipment to generate mechanical force for peeling Rice milling, if the force is mainly pressure, the form of peeling is regarded as rubbing off, and if the peeling is achieved at high speed, the form of peeling is converted into milling. The invention patent application with the application number ZL201510416104.5 discloses a rice milling The rice milling machine is configured by arranging the fine-tamping part and the driving part on a mechanism platform that can be overlapped and connected, and the mechanism platform constituting the above-mentioned rice milling mechanism is placed on the base platform, and the application number is ZL201810813192.6 Invention patent Disclosed is a rice milling machine, which is easy to control the load of the machine, and can accurately adjust the rice output accuracy in real time, reduce the broken rice rate and increase the rice output rate; at the same time, it can also effectively separate the broken rice and bran from the rice grains, Clean rice grains are thoroughly selected by winnowing to finally achieve the purpose of making polished rice; but the rice milling device in the prior art cannot accurately peel the brown rice, and often makes the peeled brown rice and unpeeled brown rice mixed together, and It cannot effectively prevent the mis-separation of unpeeled brown rice, and cannot guarantee a certain accurate peeling rate
