Product Description

ROTOCONE VACUUM DRYER

DESCRIPTION

Most Suitable for drying of materials which cannot resist high temperature, material which are easily oxidized, volatile materials which should be retrieved, materials strong irritant and poisonous in nature. The rotocone dryer with improved technology integrates during operation under vacuum. The Dryer rotates at a very low speed (5 – 10 rpm) and thus has very low wear and tear and requires very little maintenance. This machine is ideal for crystalline products, granules used in chemical, pharmaceutical and food industries. Recovery of Loss of material is effectively collected by a specially designed pilot filter fitted on the vacuum side, Solvent recovery is through condenser & receiver. The capacity of the machine ranges from 25 liters to 5000 liters.

The rotocone dryer is working under vacuum, facilitates enhanced drying efficiency, low temperature operation and economy of process by total solvent recovery. Due to vacuum, the drying is enhanced resulting in fast drying, cutting the process time, which saves heat energy and electric energy.

ADVANTAGES

  • Reduces drying time.
  • Uniform material shuffling over the heated contact surface of the cone.
  • Handling and exposure of final product is avoided.
  • Eliminates need for re-drying of lumps.
  • System can process crystalline or amorphous powders which are prone for lumps.
  • Optimum and continuous vacuum during process.
