Vacuum Drying uses vacuum pump to pump damp air out and make the working chamber form vacuum status. and let the raw material to be dried at vacuum condition ,Therefore, the drying speed of raw material is improved and the energy is saved greatly. Because the raw materials load inside the tray (standard tray size :640x460x45mm), so It is static vacuum dryer, the form and structure of material can't be damaged when be dried
Notes: The solvent of raw material can be collected by using a condenser. If the solvent is water, the condenser is not required in order to save investment cost.
１. Before drying, the treatment of disinfection may be carried out. During the period of drying, there is no impurity material mixed. It is in conformity with the requirement of GMP.
2. 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.
4. Machine materials : AISISUS304 , AISISUS316L, and other material .
5. For the electrical component , we mainly use international brand such as ABB ,Siemens or Schneider.
6.The heat source for evaporation may be low pressure steam or surplus heat steam.
7. Under the condition of vacuum, the boiling point of raw material will decrease and make the evaporation efficiency higher. Therefore for a certain amount of heat transfer, the conducting area of dryer can be saved..
8. It belongs to static dryer. So the shape of raw material to be dried should not be destroyed.
9. Highly polished inner and outer surfaces of the machine, no dead comer, easy to clear, no cross contamination. Confining to the requirement of GMP.
1.Under the condition of vacuum, the boiling point of material solution will reduce. It will increase impetus for heat and mass exchange. Therefore for certain heat exchange amount, it can save heat exchange area of evaporator.
2. The heat source for evaporating operation may be low pressure steam or waster heat steam (If having special requirement, customer may choose water or oil to heat. Our factory can design specially for you).
Suitable for drying thermal sensitive material that is easy to decompose, polymerize or denature.
Before drying, it can carry out disinfections. During the period of drying, any impurity can't be mixed into it.
It is static vacuum dryer, the form and structure of material to be dried can't be damaged.
It is suitable for drying heat sensitive raw materials that can decompose or polymerize or deteriorate at high temperature. It is widely used in pharmaceutical, chemical, foodstuff and electronic industries．
