Big capacity high efficiency alfalfa rotary dryer

shows the features of perfect drying effect, easy operation, high efficiency and easy control of drying. It takes advantage of the stability of roller and homogeneity of air. This equipment makes the combination of roller and pipes which increase the drying strength and reduce the manual power. This is the ideal equipment for drying raw materials with high humidity.

Drying Processing

Big capacity high efficiency alfalfa rotary dryer’s heat source is a combustion apparatus. It adopts direct flow heating with heat source from firing unit. The material to be dried is pushed back immediately by spiral board after going in the shell from feeding tank or feeding chute. Because the drier is installed in an inclined position, material flows to the back end under gravity and rotation force. At the same time, it is lifted by board repeatedly and thrown down accordingly, which makes the material form an even curtain, so that it can exchange heat sufficiently with the heat flow. At last, water in the material is dried by repeatedly scattering.

Machine Structure

Big capacity high efficiency alfalfa rotary dryer is mainly composed of rotary drum, lifter ,driving device,sealing ring and other components.
