Conical Vacuum Dryer and Mixer

The Conical Vacuum Dryer and Mixer is an equipment used for rapid drying and mixing of sterile raw materials. It adopts an advanced conical spiral belt structure, with a filling rate of over 70%. Added a pulse mixing device to make the materials mix more quickly and evenly ​; Adding heating function to the screw belt stirring greatly improves the drying efficiency. Efficient, energy-saving, and safe, more suitable for the requirements of drug production.
Filling rate up to 70%
complies with GMP standards
complies with FDA regulations


Conical Vacuum Dryer and Mixer is a new generation product developed by AGT for rapid drying and mixing in sterile APIs. The new product adopts impulse mixing device, which makes mixing having higher speed and more uniformity; the heating function on the spiral belt mixer can achieve higher drying efficiency. High efficient, energy saving, safety, meets higher requirement of pharmaceutical production.


Powder mixing and drying on pharmaceuticals, biological products, fine chemicals and food industry.


Main components:

  • Conical tank
  • Transmission device
  • Double spiral belt mixer
  • Pulse mixing device
  • Sampling and discharging device
  • Electronic control system
  • CIP and SIP.

Working principle

After feeding, the double spiral belt mixer revolves driven by motor and speed reducer. It makes the material revolve along with conical tank surface, lifting from the bottom up. When the material reaches zenith, inner material flows to the vortex center and back to the bottom due to gravity, and make the material mixing automatically. Meanwhile, the material can be heated in conical tank. During the all-directions irregular reciprocating motion process, heat exchange can be done between material and spiral belt and tank surface, and can achieve fast mixing and drying under vacuum condition.

Structure characters

  • Fully closed sterile structure of tank, with concise and no dead corner of inner structure, it is especially well with mixing and drying of material of flammable and combustible, toxic or highly toxic, pollution not allowed or sterile required food, biological products, pharmaceuticals.
  • Advanced conical spiral belt mixer structure, high filling ratio of more than 70%, can save occupied area and cost.
  • Conical tank, smooth discharge without residue.
  • High automation, greatly reduce labor intensity and save labor costs.
  • Tank, cover and agitator can be heated, large heating area and high heating efficiency, greatly save the working time.
  • Adopting double pivot location structure of spiral belt design, smaller radial swing parameter, smaller safety space between spiral belt and tank surface, and the damage to mechanical seal can also be reduced.
  • Sampling valve with special design can be completed in closed vacuum.
  • Discharging valve with nitrogen purging, adopts gas floating seal structure, concise and no dead corner, completely conforms to the clean production requirements of GMP and FDA.
