Double Conical Vacuum Dryer (drier)

                                                                       (Double conical vacuum dryer patent)

Principle
As a specialized company in drying industry, we supply hundred sets to the customers every year. As for working medium, it may be thermal oil or steam or hot water. For drying the adhesive raw material, we have designed specially a stirring plate buffer for you. The biggest may be 8000L. Let heat source (for example, low pressure steam or thermal 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 be realized; The raw material is under vacuum. The drop of steam pressure makes the moisture (solvent) at the surface of raw material reach the state of saturation and evaporate. The solvent will be discharged through vacuum pump and recovered in time. The inner moisture (solvent) of raw material will infiltrate, evaporate and discharge continuously. The three processes are carried out unceasingly and the purpose of drying can berealized within a short time.

Features
1.When oil is used to heat, use automatic constant temperature control. It can be used for drying biology products and mine. Its temperature of operation can be adjusted form 20-160 ℃ . 
2 .Compared to ordinal dryer, its heat efficiency will be 2 times higher. 
The heat is indirect. So the raw material can not be polluted. It is in conformity with the requirement of GMP. It is easy in washing and maintenance.

Technical parameters

Remark

1. Speed adjusting motor of 0-6rpm might be chosen according to the user's requirements. The following aspects should be point out when to order: 
2.  The above-mentioned parameters are calculated based on material density of 0.6g/cm3. If it's over, please point out. 
3.  If certificate for pressure vessel is required, please point out. 
4.  If glass lining for interior surface is required, please point out.
5.  If the material is explosive, or flammable, the calculation should be made according to trial result.
