Double Cone Vacuum Dryer
Raw material are charged as a batch & is subjected to indirect heating while undergoing rotary action. The conical shape of the dryer ensures efficient circulation of hot liquid heating media. The drying operation is being at low temperature under vacuum, that is why it is economical & effective for drying pharmaceuticals, temperature sensitive or easily oxidizable products. When the solvent is present in the wet powders, the recovery of solvent is easily possible.
Drying take place when the dryer is heated from outside through jacket & vacuum is applied from inside. The drying operation is based on the principal that water or other volatile product moves from a zone of high vapour pressure to a zone of low pressure. This is accomplished by warming the product to be dried to raise the vapour pressure of the absorbed or free liquid, by decreasing the vapour pressure of the gas by vacuum, or by sweeping it away with an air current. Thus the essential conditions for effective drying are efficient & uniform heat transfer throughout the batch & rapid removal of the vapors.
The dryers are designed to meet customer's requirements flexibly & efficiently.
Material of construction : AISI304-304L/316-316L
We provide Quality Documents like D.Q / I.Q./ O. Q. & Operation Manuals with all test Certificates. We Also provide test & calibration certificates with each instrument & traceability to National & International standards.
Low temperature drying under the state - of - vacuum inside.
Very High efficient for uniform drying in a short time as co-efficient of thermal transmission is high.
Dryer can be used for mixing / blending in its single unit.
Solvent recovery can be carried out
Specially designed micro air filter can be provided on receiver while breaking vacuum for safety operation.
Easy to clean.
The discharge of the dried material is easy due to the conical configuration of the dryer & it is possible to fix vibrator.
Nitrogen purging system is available for mechanical seal as well as for cleaning filter.
