According to the difference in the thickness of paddy rice, the suitable spacing of the ridged grain mill rollers is adjusted. After each adjustment, the surplus rice of the same variety is required to be tested, and all varieties are subjected to a uniform shelling rate of 97% as a unified implementation standard. Due to the raft mill wheel spacing is too large or too small affect the measurement results. In addition, it is necessary to ensure the stability of the burrowing machine's injection speed as much as possible so as to avoid swiftness and slowness.

The rice mill needs to pay attention to the best grinding amount and grinding time of the rice mill in the process of use. The grinding mill used in this experiment has an optimal grinding capacity of 20 g and a white grinding time of 75 s. In the rough and fine grinding process, it is best to have a dedicated person responsible for the end, try to avoid substitution in the process, due to human factors and affect the measurement results.
The effect of moisture content on the rate of whole polished rice: If the moisture content is too high, the strength of the grain will be reduced, resulting in more broken rice in the processing, and the rate of whole polished rice will be reduced accordingly; but if the water content is too low, the grain of rice will become brittle, and It is easy to produce broken rice and reduce the rate of whole polished rice. Generally, the paddy rice moisture content should be controlled at about 14% during the processing of early indica rice. In this experiment, the whole milled rice rate was generally lower when all the varieties were dried at 50°C for 1 h. At this time, the corresponding brown rice had a moisture content of about 14% (see Table 4). When the rate of whole polished rice is high, the moisture content of the corresponding brown rice is about 12%. Therefore, in this study, in order to obtain a higher rate of milled rice, when milling into polished rice, the moisture content of brown rice should be controlled at about 12%.
The advantages of rapid rice identification with oven rice processing:
1. Save time: After harvesting, the materials need not be aired or placed waiting. After being mixed, they can be directly processed into the oven to measure the rate of whole polished rice. With the collection and testing, it is flexible and convenient.
2. Use less: only about 30 g of rice is required for each repetition, the number of general breeding materials in the field can meet the analysis requirements, and the analyzed samples can be used for further physical and chemical quality determination, and provide better reference for species selection.
3. Mass determination: 2 ovens, set at 50°C and 60°C, respectively. Repeat 2 times for each variety. Only 4 Petri dishes with 10 cm in diameter are required. Rice is evenly distributed and placed in 2 ovens. The grain variety was dried at 60°C for 4 h and 50°C for 6 h, and the short grain variety was dried at 60°C for 5 h and 50°C for 8 h. The medium and long grain varieties were baked at 60°C for 4 h and then at 50°C. 8 Take out, can measure dozens of varieties at a time in the oven, improve the efficiency greatly.
