1, because it is dried under vacuum, at a lower temperature have a higher rate than the average 2 times faster drying equipment, energy conservation, thermal efficiency, especially suitable for drying heat sensitive materials and easy oxides. 
 2, the machine is advanced in design, the internal structure is simple, clean easy, all the discharged material can be easy to operate. 
 3, the material in the rotating mixing dry, can be drying water content (0.5%) are uniformly good. 
 This equipment is mainly used in pharmaceutical, chemical, food industry drying the following: 
 ① can not withstand high temperature materials. 
 ② easily oxidized materials. 
 ③ not allow destruction of the crystal material. 
 ④ recycling residual volatile material factors. 
 ⑤ strongly stimulated, toxic materials.
