Therefore, rice polishing is an indispensable procedure in the rice finishing process flow. The rice polishing refers to removing broken rice and bran pieces after the brown rice is polished by a multi-machine, spraying water and wetting rice, entering a polishing chamber of a polishing machine, and polishing the surface of rice grains by friction under certain pressure and temperature. Through polishing treatment, not only the floating bran on the surface of rice grains can be removed, but also the functions of pregelatinization and gelatinization of starch on the surface of rice grains are achieved, and the gelatinization of starch makes up cracks, so that the appearance quality with crystal and clear color is obtained, and the storage performance and practical quality of rice are improved.
The polishing degree analyzer is used for detecting polishing degree of rice grains such as rice, and mainly comprises a rice distribution mechanism and a detection mechanism, wherein the rice distribution mechanism moves above a rice grain bearing surface and distributes rice, then the rice distribution mechanism exits from the above of the rice grain bearing surface, the detection mechanism is driven by a driving mechanism to come above the rice grain bearing surface, the polishing degree of the rice grains on the bearing surface is comprehensively detected under a moving state, then the detection mechanism exits from the above of the rice grain bearing surface, the rice grain bearing surface is overturned, the rice is put into a recovery groove, finally the rice grain bearing surface is reset, and the rice distribution mechanism continues the next round of rice distribution operation. The existing analyzer has the following problems in the use process:
1. The situation of overlapping grains can exist due to insufficient uniform rice distribution, so that the detection precision of the analyzer is reduced; 2. the rice distributing mechanism reciprocates the rice above the horizontal bearing surface, then the bearing surface vibrates through the vibrator to enable the rice grains to be uniformly distributed again, finally after the image detection mechanism collects the images, the bearing surface turns over to fall the rice, the rice distributing mechanism distributes the rice again, the working mode needs a plurality of driving mechanisms for assistance, the rice distributing efficiency is low, and the failure rate is high; 3. rice dirt falling above the bearing surface along with rice grains is easy to adhere to the bearing surface, and cannot be easily removed after excessive accumulation, so that the later detection result is affected; 4. because the bearing area is limited, the image detection mechanism and the rice distribution mechanism work above the bearing surface alternately, and the detection work is intermittent, however, for the polishing degree detection index, the average finish degree and the surface brightness change of rice grains are detected for uninterrupted rice flow in continuous time, and the structural form cannot meet the detection condition, so that the detection precision of the current image detection mechanism is lower.
In conclusion, the existing polishing degree analyzer has the problems of low detection precision, high failure rate, high manufacturing cost and incapability of realizing online long-term continuous detection. Based on this, improvements are urgently needed for the existing polishing degree analyzers.

Working principle:
The rice flows into the vibration rice bucket 10 through the lower rice pipe assembly, and the sponge supporting body 11 is arranged between the lower rice pipe assembly and the vibration rice bucket 10, so that the vibration of the vibration rice bucket 10 is not limited by the position of the lower rice pipe assembly, no gap is kept between the lower rice pipe assembly and the vibration rice bucket 10 in the vibration process, and in addition, the lower rice pipe assembly is provided with the silica gel pad 12, so that the rice is rebounded and bumped onto the silica gel pad 12 after falling into the vibration rice bucket 10, and the rice is prevented from jumping out of the vibration rice bucket 10. The vibrator 15 drives the vibrating rice bucket 10 to vibrate, so that rice uniformly flows onto the rice grain flowing disc 8, and meanwhile, the flow of the rice can be controlled by adjusting the amplitude of the vibrator 15, and the long strip-shaped through grooves 801 on the surface of the rice grain flowing disc 8 are uniformly distributed in the rice grain flowing process. The relative angles of the support 18 and the overturning support seat 17 are adjusted by adjusting the angles of the two sides of the rice grain flow disc 8, so that the inclination angle of the rice grain flow disc 8 is adjusted, the rice flow down speed is further controlled, and the rice grain flow is controllable. The electric heating sheet on the back of the rice grain flow disk 8 softens the rice scale accumulated on the surface of the rice grain flow disk 8, so that the rice scale is taken away by the flowing rice grains and cannot accumulate on the rice grain flow disk 8.
The rice grains flowing down from the rice grain flowing tray 8 continuously and uniformly slide through the transparent cover plate 21, and with the aid of the front and rear light sources 47, 42, the camera performs real-time uninterrupted image shooting, and transmits image data to the computer terminal for analysis and calculation, so as to obtain detection data. The fallen rice grains are recovered by the recovery tank 23 and returned to the in-line production line through the recovery line.
The foregoing describes the embodiments of the present invention in detail, but the description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. All equivalent changes and modifications within the scope of the present invention are intended to fall within the scope of the present invention.
