Our double cone vacuum dryer is used economically and effectively for drying pharmaceuticals, temperature sensitive or easily oxidizable materials, when the solvent is present in the material, its easy recovery is possible. Drying takes place when the blender isolated & heated from outside the jacket and Vacuum is applied in the internals.
All drying operations are based on the principle that water or other volatile material moves from a zone of high vapour pressure to a zone of lower pressure. This is accomplished by warming the material 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 AND UNIFORM HEAT TRANSFER THROUGHOUT THE BATCH AND RAPID REMOVAL OF THE VAPOUR.
