Rotocone Vacuum Dryer

Rotocone Vacuum Dryer

Roto Cone Vacumm Dryer is suitable for drying of materials which cannot resist high temperature, materials which are easily oxidized, volatile materials which should be retrieved, materials that are strong irritants and poisonous in nature. The Roto Cone Dryer with improved technology integrates during operation under vacuum. The Roto Cone Dryer facilitates enhanced drying efficiency, low temperature operation and economy of process by total solvent recovery. It helps cGMP base working by achieving optimum dust control, while offering advantages of efficient charging and discharging of materials.

The drying unit equipped with lump breakers initially breaks large lumps and subsequently powders them (in a single cone). The rotary action of the dryer together with mechanical action of the breakers cuts down drying time and gives a lump-free product.

Technical Spacification

• Reduces drying time
• Eliminates need for re-drying of lumps
• Handling and exposure of final product is avoided
• Gives uniform size dry product. System can process crystalline or amorphous powders which are prone to lumps
• Easy to clean internal surface ensures purity of product . Optimum and continuous vacuum maintenance during process
• Uniform material shuffling over the heated contact surface of the cone.
