High quality vacuum dryer/vacuum belt dryer

Principle of the vacuum belt dryer:

1. Let heat source (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.

2.Under driving of power, the tank is rotated slowly and the raw material inside it is mixed continuously. The purpose of reinforced drying can realized.

3. The raw material exists at the state of vacuum. The drop of steam pressure makes the moisture (solvent) at the surface of raw material become saturation and will evaporate. The solvent will be discharge continuously. The three processes are carried out unceasingly and the purpose of drying can be realized within a short time.

Character of the vacuum belt dryer:

1. two connecting ways: pulley or chain, to make the machine stable in operation
2. Good concentricity. Heat medium and vacuum system all adapt reliable machinery seal or rotating joint
3. as for working medium, it may be high temperature conduction heat oil or middle temperature steam. For drying the adhesive raw material, we have designed a stirring plate for you
4. When the 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 from 20-160°Cand within±2°C
5. compared with ordinal drier, its heat efficiency will be over 2times
6. 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

Notes: for raw material, if its volume has great change before and after dry, then its filling coefficient may be increased or decreased suitably.

Applications of the vacuum belt dryer:

1. The raw materials that need to concentrate mix and dry at low temperature, such as biochemistry products in chemical, pharmaceutical and foodstuff industries.
2. The materials that are easy to oxidize volatilize and have strong heat sensitive and toxity and not permitted to destroy its crystal in drying.
