III. Multi-functional

Conical screw vacuum mix/dryers are applicable in various fields; particularly suitable for process handling in sealed and controlled environments, the chemical industry, additives, crystalline extracts that are unstable under air or high temperatures, and various bioprocesses. The versatile conical screw vacuum mix/dryer equipment for force drying is the ideal choice to meet your production needs.

Section 4: Vacuum Drying 
The conical screw vacuum mixer/dryer is a multifunctional unit that integrates mixing, drying, and distillation. Featuring a fully enclosed GMP clean design, it boasts a drying efficiency 3-5 times that of its equivalent size (double cone rotary vacuum dryer), with a loading capacity reaching up to 80% of the cone volume, resulting in a relative efficiency improvement of 6-10 times. The spiral screw mixer ensures a spiral circulation of the material from bottom to top, achieving effective heat transfer. Operating at a filling rate of 30%-80%, it offers satisfactory utilization efficiency of the heating area. It is an energy-saving, environmentally friendly, and clean new drying equipment.

V. High Mixed Precision
Achieve high mixing accuracy. Even when mixing materials of different densities and particle shapes within the same batch, the conical mixer can achieve the desired mixing precision. Under stringent conditions such as adding a small amount of material to a large volume, mixing can also be performed in the cone screw vacuum mixing/drying machine for strength drying.

 
Six: Low Shear Impeller Mixing
Utilizing a low-shear blade agitator, the material is gently mixed at low speed and low energy consumption. The intensity and mixing time of the mixture are both low.

Seven, Suitable for Adhesive Materials
Under the action of friction and pressure between material particles during mixing, even materials with strong adhesiveness can be separated and effectively blended.

Section 8: Varying Material Loading Rates
The conical screw vacuum dryer has a filling rate of 30% to 90% of the effective working volume, within which mixing and drying of different filling quantities can yield consistent results.

 
Section 9: Sealed and Clean Design
The conical screw vacuum mixer/dryer is a fully enclosed design, with all connecting components, including feed and discharge, being fixed, meeting safety requirements for materials and the environment.
