Features:
Because the hot air passes through the layer of raw material several times and acts counter motion towards the raw material,the heat exchange is fully used and the thermal efficiency is high;
The structure is compact and it occupies small area;
The stay time of raw material in the helix bed can be adjusted and the operation is very convenient;
The raw material acts teh motion of circle at helix bed from up to Iow,at the same time the equipment can jump itself,so the contact surface between hot air and raw material increased too and the dry effect is strengthened;
The equipment is suitable for continous operation because of continulus feeding and discharging raw material,Meanwhile it is easy to meet the require- ments of "GMP".
It does not damage te surface and shape of raw material basically. It can not only maintain the roundness of pill but also decrease the broken rate of pill.

Working principle:
The damp raw material enters into helix bed from fed inlet at the top and moves along with the helix bed from up to Iow and make jumping motion 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 materials 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.

Application:
LZG helix vibration drier is mainly used for drying pill of Chinese traditional medicine. It can also be suitbale for drying granule,short strip and ball raw material of chemical industry,pharmaceutical industry,foodstuff industry,construction material industry,feed industry and so on .
