SZG Series Double Cone Rotary Vacuum Dryer

Product Name:SZG Series Double Cone Rotary Vacuum Dryer

Keywords:SZG Vacuum Dryer, Double Cone Rotary Vacuum Dryer,Rotary Vacuum Dryer
Overview:The vessel rotates to continuously change the heating surface of materials. With the high speed and even drying, it has no pollution to material and is operated and cleaned easily. In addition, the optimizely-designed seal has good sealing effect and convenient mainetance.


The main body of SZG series double cone roating vacuum dryer is double cone tank, steam or heat water inside sealed jacket can heat the inner shell in vacuum state, the hot transferred from inner shell to dump material. Make moisture vaporize from material. The tank is rotating by the motor with low speed, the material is moving up and down, inside to outside along, at the same time vapour is taken out continually through vent-pipe by vacuum pump, increase the speed of dryer, attain the purpose of uniformity drying. It is in comformity with the requirement of GMP.

◎Let heat source (for example, low pressure steam or heat conduct oil) pass through the sealed jacket. The heat will be transmitted to raw material to be dried through inner shell;
◎Under driving of power, the tank is rotated slowly and the raw material inside it is mixed continuously. The purpose of reinforced drying can e realizd;
◎The raw material exists at the state of vacuum. The drop of team pressure makes the moisture (solvent) at the surface of raw material become saturation and will evaporate. The solvent will be discharged through vacuum pump an drecovered in time.The inner moisture (solvent) of raw material will infiltrate, evaporate and discharge continuously. The three processes are carried outunceasingly and the purpose of drying can be realized within a short time. 


1.Because of drying in vacuum, it has high speed under low temperature, it's drying speed has raise 2 times, save sources, and the heat efficiency is high, especially adapt material which is heat sensitive and easy oxdiated.

2.The equipment adopt advance desigh, the inner structure is simple, cleam easy, material can be taken out entirely and operate simple

3.Dry sealed, the product which doesn't  leak, pollute. And it is suitable for the dry of stimulative and poisonous material.

4.Raw material is dried and mixed when it is rolling, it can be dried  to a low moisture (

≦0.5%), and own good uniformity. The equipment is suitable for all kinds of raw material.

5.The strcuture of the equipment is tight, occupy small area, operate simple and save work force.

6.Custom can section stepless regulation (6-10r/m) and step regulation (6-10r/m), it is easy to adjust drying capacity and adapt different requirement.

It can widely apply to dry raw materials of pharmaceutical industry, chemical industry, foodstuff industry, dyestuff industry and so on.
