Different processing methods have different effects on the quality of food products, the following millet as an example, respectively, the two processing methods are briefly introduced.

Multistage light grinding method refers to the millet classification after the use of multiple rice milling method, millet processing. The process flow is: millet - removing impurities - husking - separating - 1 grinding - 2 grinding - 3 grinding - grading - absorbing bran powder and cooling - packaging - no-wash millet. Grain processing equipment using this processing method has the following characteristics: no need to add any polish, simple operation, suitable for small project production. However, the quality of disposable millet is not high, the nutritional loss is more, and the content of broken rice is higher.

Membrane method: The starch grains on the surface of millet are transformed into gelatinous starch film wrapped in rice grains through pre-gelatinization, so as to produce no-wash millet, this method is called membrane method, and the key process of membrane method to produce no-wash millet is to remove the light on the bran. The essence of glazing is to use millet surface starch particles to produce pre-gelatinization in the Polishing machine, which is to form an extremely thin gelatinized starch film on the surface of rice grains.

Compared with the multistage light grinding method, the film method has the following characteristics: the process is simple, easy to operate, the polish agent added on the surface of the rice to form a protective layer, improve the finish of millet, improve the quality of no-wash millet, and maintain a long time, resistance to friction and temperature and humidity changes, can prevent the contact between the rice and the air, prevent oxidation, thus extending the shelf life of millet. However, the concentration and amount of polishing agent are difficult to control, and the equipment is easy to lose.
