¡ñThe damp raw material enters into helix bed from fed inlet at the top and moves along with the helix bed from
up to low and make jumping mot ion to the bottom and then discharge under the action of vibrating force at the
circle and gravity. Meanwhile clean hot air enters into it from the bottom of helix bed and carries out heat exchange with raw material on the helix bed fully and exhausts from the outlet at the top. In this way the dry
purpose of damp raw material is reached.
¡ñThe drier is mainly used for drying pill of Chinese traditional medicine. It can also be suitable for drying
granule, short strip and ball raw material of chemical industry£¬ pharmaceutical industry£¬ foodstuff industry£¬ construction material industry feed industry and so on.


¡ñThe machine is used for drying grain, strip, dollop of pill, foodstuff catalyzer, chemical industry, foodstuff, structural material.

¡ñBecause the hot air passes through the layer of raw material several thimes and acts counter motion towards the raw material,the heat exchanges is fully used and thermal efficiency is high.
¡ñThe structure is compact and it occupies small area.
¡ñThe stay time of raw material in thehelix bed ca be adjusted and the operation is very convenient.
¡ñThe raw material acts the motion of circle at helix bed from up to low,at the same time the equipment can jump itself,so the contact surface between hot air and raw material is increased too and the dry effects is strengthrned. 
¡ñThe equipment is suitable for continuous operation because of continuous feeding and discharging raw material .Meanwhile it is easy to meet the requirements of "GMP"
¡ñIt does not damge the surface and shape of raw material basically.It can not only maintain the roundness of pill but also decrease the broken rate of pill.
