Promas Engineers Pvt. Ltd
Rotary Cone Vacuum Drier (RCVD)Rotary Double Cone Vacuum Dryer:
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.
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.
- Low temperature drying under vacuum
- Highly efficient for uniform drying in a short time as co-efficient of thermal transmission is high
- Solvent recovery can be carried out
- Specially designed micro air-filter can be provided on receiver while breaking vacuum for safety operation
- 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 optionally for mechanical seal as well as for cleaning filter
- Specially designed S.S. Rotary union is provided for hot water or steam at inlet & outlet
- Mode of heating is indirect through steam / hot water or hot oil
- A self-cleaning butterfly discharge valve with safety blind cover
- Internal cartridge filter for fine powders with effective surface area
- Available in STD/GMP/cGMP/GAMP/ GLP/ GCP/Lab Models and kilo lab models
