Double Cone Vacuum Dryer with Heating System And Vacuum Jet Ejector

Product Description

Double Cone Vacuum Dryer with Heating System & Vacum Jet Ejector

Applications

RCVD is suitable for drying & mixing powder (raw materials), pharmaceutical materials, crystalline products, insecticides, pesticides, food products & also for heat sensitive products. The equipment can also be used as rotary evaporator.

Working Principle

Raw material is charged in batches & is subjected to indirect heating while at the same time undergoing rotary motion of the cone assembly. The conical shape of the dryer ensures efficient circulation of hot liquid heating media.

Drying takes place when heat flows from outer cone through a jacket, and vacuum is applied in the inner cone. The drying operation is based on the principle that water or other volatile product moves from a zone of low pressure. This is accomplished by warming the product to be dried to raise the vapour pressure of the 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 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.

The drying time is substantially reduced because of high-speed choppers, which help the evaporation of the solvent or moistures. Chopper speed can be controlled by a frequency drive. Dryer are manufactured as per "US-FDA" Standards & Regulations.
