In the fiercely competitive wheat flour market, no matter which flour company wants to improve its own flour quality. When the whitening agent is used, it partially masks the importance of wheat quality, flour milling equipment and process technology in flour milling. After the whitening agent is prohibited from being added, the flour owners have to pay more attention to wheat quality, flour milling equipment and process technology to Ensure that the quality of the flour produced by your company is more competitive.
Maximize the utilization rate of wheat, increase the proportion of high-quality flour and improve the quality of flour. As we all know, the internal cause of flour quality depends on wheat quality, and the external cause depends on process equipment and operation management. Regardless of the flour companies that are going to be built, are under construction or are going to be rebuilt, in order to achieve the goal of high flour yield and high-quality flour, more and more attention is paid to the role of flour milling equipment in flour milling. Relatively speaking, the purchase cost of the powder cleaner is not high, the maintenance and use costs are low, and the powder cleaner can play a role in improving the quality of the flour and the yield of high-quality flour. Therefore, the powder cleaning machine is more and more favored by powder mills. At present, the powder mill industry is forming a trend of increasing the number of powder cleaning machines and expanding the scope of use.
Flour cleaner is a kind of grain processing machinery. Flour cleaning machine is a kind of grain processing machine. A machine that separates pure and relatively pure endosperm particles from the material milled by a mill. It is composed of a screen body equipped with a double-layer 2-layer screen surface or a double screen body equipped with a 2- or 3-layer screen surface, equipped with an air duct and an air chamber, etc. Each screen surface is composed of 4 screens equipped with different screens The sieve grid is formed in series. The screen body is supported by four rubber springs with different rubber sizes, and is driven by an eccentric vibration motor.
The airflow passes from the bottom of the screen body upward through the 2 or 3 layer screen surface and enters the 32 air chambers at the top of the screen body. The air volume is adjusted by the two air chamber interfaces. The combined effect of vibration, screen and air flow can loosen the materials entering the powder cleaner and are roughly divided into 3 layers according to specific gravity, granular shape, surface properties and aerodynamic characteristics. The light bran is sucked away, and the endosperm with the skin as a sieve The above product is output and sent to the mill to circulate and remove the endosperm particles with the skin again; pure and relatively pure endosperm particles are used as the under-screen material and then enter the mill, which is further ground into flour. The 49 powder cleaner and 60 powder cleaner are widely used now.
In 1987, my country introduced a small batch of trial production from abroad. In 1994, the molding was mainly used for the production of special grade flour at that time. In 2002, the flour mill began to be widely used.
