What is the Technological Process of Grain Processing Equipment?

The process of food processing can be divided into two categories:

One type

It is to dehull, peel and grind raw grains such as rice, sorghum, millet, and millet into granular finished grains;

Another kind

It is to remove the cortex and germ of raw grains such as wheat, corn, barley, buckwheat, naked oats, and grind them into finished flour.

Seed Processing Machine

As a Seed Processing Machine Manufacturer, I would like to share with you the general process of raw grain processing such as rice.

The raw grain is firstly cleaned by the cylinder, and then passed through the reciprocating vibrating screen, high-speed vibrating screen of high-seed cleaning machine, specific gravity stone removal machine and magnetic separation equipment (see grain cleaning machinery) to remove various impurities, and then enter the hulling machine. Take off and separate the rice husk. The discharged grain and brown mixture is sent to the grain separation and seed sorting machine for off-machine. In China, the main development of the flat rotary grain separator is to use the difference in particle size, specific gravity, friction coefficient and elasticity between rice and brown rice to separate the unhulled rice and send the seed cleaning machine back to the hulling machine; brown rice Then enter the rice mill to make white rice. After finishing the finished product, the broken rice bran is removed to obtain the finished white rice. Rice mills are commonly used in rural China to directly process rice into white rice, but the seed-cleaning machine has a lower rate of rice and more broken rice. The process flow of rice milling and the main equipment used are shown in the figure. The process of wheat processing is that after the raw grain is initially cleaned by the primary cleaning sieve, various impurities and the mud and dirt adhering to the surface of the wheat grains are removed by the vibrating sieve, wheat threshing machine, selection machine and wheat washing machine. After cleaning, the clean wheat is removed by magnetic separation equipment and then enters the mill to grind into powder. After sieving through a flat screen, the flour is extracted. The intermediate material of the seed cleaner enters another mill to grind, and the extraction is repeated. Flour, the bran is processed by a bran brushing machine and a round sieve before being discharged. When making special or high-grade flour, a powder cleaner is also used to separate pure and relatively pure endosperm particles from the intermediate material discharged from the mill and flat screen, and further grind them into special and high-grade flour.
