Abstract: 5HCCX-1.6 recalculating impinging crossflow dryer was introduced in this paper. Forage seeds are of many different varieties, and their structures are complex, furthermore, their biological activities are fragile, so it is hard to design and apply equipment for drying them. In order to confirm the performance of the dryer and its action on forage seeds, Medicago sativa seeds, Aneurolepidium Chinese seeds and Elymus dahuricus seeds were chosen as testing seeds for their typical plants in China. According to the International Seeds Test Standard and the Test Evaluation Method for Seed Dryer, experiments for drying Medicago sativa seeds, Aneurolepidium Chinese seeds and Elymus dahuricus seeds were completed. It was found that diverse seeds with different original water content could be dried to safety values(≤12％); Their qualities were improved obviously, such as the germination number of Elymus dahuricus seeds turned from less than 80％ to greater than 85％, and that of Medicago sativa seeds got to over 90%, but before being dried, it was only 85%, these show that the dryer is suitable for different kinds of forage seeds with diverse morphosis.
