Vacuum rake dryer continues to be popular

Vacuum rake dryer has the advantages of simple structure, convenient operation, long service cycle, stable and reliable performance, small steam consumption, strong applicability and good product quality. It is especially suitable for drying paste materials which are not resistant to high temperature, flammable and easy to oxidize under temperature regulation. It has been proved to be a good drying equipment by users for a long time. Principle: the dried material is added from the middle of the shell, and the rake is continuously rotating forward and backward

It is especially suitable for drying paste materials which are not resistant to high temperature, flammable and easy to oxidize under temperature regulation. It has been proved to be a good drying equipment by users for a long time.

Principle: the dried material is added from the middle of the shell. Under the stirring of the rake teeth, the material moves back and forth in axial direction, and the surface contacting with the inner wall of the shell is constantly updated. It is indirectly heated by steam, evenly stirred by the harrow teeth, and crushed by the grinding rod, so that the moisture on the surface of the material is discharged more favorable. The vaporized water passes through the dry-type dust collector, the wet dust collector and the cold-rolled one Condenser, vent from vacuum pump outlet

Development trend of grain drying equipment

Abstract:

In view of the current situation of grain drying equipment in China and in combination with the market demand in rural areas, the development trend of domestic grain drying equipment is as follows:

(1) The production capacity of grain dryer should be developed to a large scale. In the future, it is necessary to develop equipment with processing capacity of 20-30 tons per hour.

(2) In order to design the equipment to reduce the high moisture grain to the safety standard at one time, it is required to reduce the rate by more than 10%. Therefore, there are two ways: one is to adopt the combined drying method, that is, to synthesize a new drying process by combining the drying units with more than two drying methods, such as preheating the wet grain with a high temperature fast fluidizing dryer, and then drying the wet grain with a rotary dryer at a lower temperature. From the current development of grain drying technology in the world, this is a trend. The second is to design high-efficiency flash dryer for grain.

(3) The application of advanced measurement and control technology can realize the development of drying process towards automation or semi automation.

(4) High temperature and fast processing of large quantities of high moisture grains.

(5) The study of coal-fired energy-saving dryer is still the main direction. Meanwhile, we should explore new energy dryers, such as microwave energy, solar energy and so on.

(6) The grain dryer in rural areas should be small and multi-functional, which requires easy movement, simple operation, less investment and can ensure the quality of grain drying.
