The selection trend of food processing equipment
The selection trend of food processing equipment
The process of food processing can be divided into two categories:
The first sort ：It is to dehull, peel and grind raw grains such as rice, sorghum, millet, and millet into granular finished grains;
The second sort：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.
General process
The processing process of the first type of grains such as rice:
The raw grains are first cleaned and screened through the cylinder, and then are removed by the reciprocating vibrating screen, high-speed vibrating screen, specific gravity stone remover and magnetic separation equipment .
Enter the hulling machine, take off and separate the rice husks. The discharged grain and brown mixture is sent to the grain separator. Using the difference between rice and brown rice in terms of particle size, specific gravity, coefficient of friction and elasticity, the unhusked rice is separated and sent back to the hulling machine;
The brown rice is milled into the rice milling machine to make white rice. After finishing the finished product, the broken rice bran is removed to obtain the finished white rice.
Some customers choose to directly use rice mills to directly process rice into white rice, but the rice yield rate is low and there are more broken rice.
The generally flow of rice milling plant
The process of the second type of grains such as wheat:
After the raw grains are initially cleaned by the primary cleaning sieve, various impurities and dirt adhering to the surface of the wheat grains are removed by a vibrating sieve, a wheat threshing machine, a selection machine and a wheat washing machine.
After cleaning, the cleaned 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 is then pulverized by another mill. The bran is discharged after being processed by a bran brushing machine and a round sieve.
When making special or high-quality 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-quality flour.

Development trend
1. The parts in contact with grain in grain processing machinery will be more alloy and non-metallic materials to prevent rust and ensure the cleanliness of the finished grain;
2. The frame will use light metal and thin-walled steel structure to reduce weight, and try to use the internal space of the equipment to arrange components to reduce the volume. The service life and interchangeability of working parts and moving parts will be further improved, while the number of fastening points and parts will be simplified and reduced to shorten the assembly and disassembly time of working parts and reduce scattered parts
3. One machine with multiple functions, as well as equipment automatic control and safety protection devices will be further developed. In addition, since wheat can be milled and milled to obtain more flour with good color, there will be more and more choices for wheat bran machines in wheat flour milling plant.
