In view of China's current situation of grain drying equipment, combined with the demand of the vast rural areas. The development of China's grain drying equipment will show the following trends.

1. The production capacity of grain drying equipment is developing towards the direction of large scale. In view of this situation, product manufacturers need to develop the equipment that handling capacity between 20 to 30 tons.

2. Design a device that can quickly reduce the moisture of the grain.

3. Using advanced measurement and control technology to realize the development of drying process to automation or semi automation.

4. High temperature and fast drying of high moisture grain.

5. Take coal as energy. In this aspect, the indirect energy saving dryer is the main direction of the industry development.
