Grading is the process of removing the broken from head rice and sorting them into well defined fractions of different length. The grading process in a rice mill plant is achieved by using rice grader machine and color sorter. The grain grader machine separates the rice into head rice, a mixed fraction (including head rice and broken) and tips. It also removes bran lumps from the product.They grade the rice by length into fractions of different broken sizes and head rice. The number of grading screen depends on the customers’ requirement.

Function Of Rice Grader Machine

Rice plays a significant role in world food industry.Rice grading is important in determining rice quality and its subsequent price in the market. It is an important process applied in the rice production industry with the purpose of ensuring that the rice produced for the market meets the quality requirements of consumer.
With the continuous improvement of the market’s requirements for rice quality, it is necessary to effectively control the content of broken rice. During processing, due to the influence of different raw materials, flow rates and processing characteristics, the work of the rice sieve is unstable. The broken content does not exceed the standard, and the decimeter sieve is required to have stable working performance and large output to ensure that the screening effect is not affected when the raw material conditions change. Therefore, if the rice grader wants to have a good working effect, it must have suitable screens and sieves, equipped with scientific movement forms and reasonable screening routes.
If you set up this rice grader machine, you can produce high quality white rice from the common rice, different clients has different requirements to meet the market demands.
