Rotary Vaccum Dryer

S.S. Engineering manufacture most economical and cost effective rotary vacuum dryers matching all the required speci􀃶cations of the clients. Rotary Vacuum Dryer for easy, clean, and effective way for drying off wet powders, wet cakes, and slurries somewhere either solvent is drying or recovered to be performed at moderately low temperature to heat sensitive materials, we are producing exceptional rotary dryer designs for various industrial purposes.

Rotary vacuum dryer is a horizontal cylindrical jacketed shell with hollow agitator, rotating in close clearance. A batch operation, drying is done under vacuum, heating is through jacket. The dryer offers a simple but effective method of drying wet cakes and sometimes slurries. Due to vacuum and agitation, it is possible to dry heat sensitive materials.

Vessel has a central agitator with designer blades, the blades of rotary vacuum dryer are responsible for sweeping the entire internal surface and blades also turn the material present in the dryer and all the particles come in contact with the heated surface.

The central agitator shaft supports the bearing housing in a way that the arrangement remains constant. The system can be cool down later by cold 􀃸owing water in jacket.

The Purpose of dust Catcher / Filter is provided to prevent carryover of dried product particles to distillate collection system and avoiding dust particle to enter in Vacuum Pump, dust catcher consist of 􀃶lter bag mounted on the top of outlet dryer column. The dust Catcher is provided jacket or Limpets for heating to avoid condensation in dust Cather.

The Condensate of the Solvent is collected in the receiver of in various capacity placed beneath the condenser.

A condenser is a heat exchanger used to condense a water vapour /solvent gaseous substance into to a liquid state through water cooling in so doing; the latent heat is released by the substance and transferred to the surrounding surface contact area of condenser tube where water is circulated.

Vacuum Pump line is given to receiver for creating a vacuum in the dryer shell, due to vacuum moisture, solvent present in drying material vacuum facilitate vapour forming in low temperature which dries heat sensitive materials.

Stuffing box or mechanical Seal as per requirement and Stuffing Box Jacket is provided for cooling to prevent burning and Charing of Gland Rope. Which give long life to gland rope, Gland pusher is provided with Gunmetal bush bearing, thus ensuring minimized friction giving longer life to the (Rotor) Shaft.


  • Uniform drying due to closure distance between blade and shell
  • No Degradation due to over-exposure, more temperature and time.
  • Automated discharge, ease of handling with condenser and receiver and recovery of solvents.
Models Available: Gross capacity from 100 litres to 20,000 Litres Material of construction: M.S, SS 304, and SS 316
