SZG Double Conical Rotary Vacuum Dryer

Hot medium is inlet jacket for drying, Heat exchange id done by the inner wall contacts with damp material. After the material absorbs heat, water is evaporated. The evaporated moisture and other gas is exhausted from vacuum exhaust pipe by vacuum pump. In the tank it is vacuum state and the rotary of tank makes the material overturn continuously, so the drying speed is fast and drying intensity is increased, and can achieve the purpose of  uniform drying. It is a new style dryer that combines mixing and drying together. It can be used together with condenser and vacuum pump(If don’t need  recover solvent, condenser is not needed).

The design is advanced, inner structure is simple and easy to clean. Material can be discharged completely and operation is simple. It can reduce the labor intensity, and improve working environment. Material will rotate with the rotary of tank, but there is no material stick on the inner wall, so coefficient of heat transfer is high, drying efficiency is high. It can not only save energy but also can dry material uniformly. It is widely used for drying in pharmaceutical, chemical, foodstuff, dyestuff industry and so on.

1.Vacuumized pipe rotates together with tank, it avoids the material pollution because of the wear of tank and vacuum pipe and the wear of sealing strip.

2.The sealing of tank two sides adopt advanced rotary joint sphere plumbago sealing technology.

3.The active support of motor can adjust the best tensioning degree of belt.

4.Inner tank, jacket and axle sleeve are welded together. Use large scale boring machine to process the flatness of axle sleeve and the concentricity of tank. It can ensure the radial runout of the main  axle two sides is less than 0.2mm.

5.There is diaphragm type vacuum meter to show the vacuum degree in the tank, it can avoid the phenomenon of false vacuum.

 The machine is suitable for vacuum mixing and drying of power and granule raw materials of pharmaceutical industry, chemical industry, foodstuff industry etc. Particularly it is suitable for row materials that have the follow requirements:

1.Themal sensitive raw materials that cannot be dried at high temperature.

2.Raw materials that is easy to oxidize and dangerous.

3.Raw materials that solvent and toxic gases are needed to recover.

4.Raw materials that have special requirement for crystal shape.

5. Raw materials that have special requirement for the content of residual colatile.
