Development trend of grain drying equipment
Vacuum 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 rural grain dryer should be small and multi-functional, which requires easy movement, simple operation, less investment and can ensure the quality of grain drying
