3、 Multi purpose
Cone shaped spiral belt vacuum mixing/drying machine can be applied in many fields; Specially suitable for process processing in enclosed and controllable environments, such as the pharmaceutical and chemical industry, as well as additives, extract crystals that are unstable in air or high temperatures, and various pharmaceutical and biological processes, Chengxin Company's multi-purpose conical spiral vacuum mixing/drying equipment is the ideal choice to meet your production needs.

4、 High efficiency vacuum drying
The conical spiral belt vacuum mixing/drying machine is a multifunctional equipment that integrates mixing, drying, and distillation. It adopts a fully enclosed GMP cleaning design, and its drying efficiency is 3-5 times that of the same specification (double cone rotary vacuum drying machine). The loading capacity is twice that of the double cone rotary vacuum drying machine, and the relative efficiency is increased by 6-10 times. The spiral stirrer can achieve a bottom-up spiral circulation mixing effect for materials, and can achieve efficient heat transfer characteristics. When the material loading rate is between 30% and 100%, it can achieve a utilization efficiency of 100% of the heating area. It is a new type of drying equipment that is energy-saving, efficient, environmentally friendly and clean.

5、 High mixing accuracy
It can achieve high mixing accuracy. Even if materials with different densities and particle shapes are mixed in the same batch of products, the required mixing accuracy can be achieved in a conical mixer. Adding a small amount of material to a large batch of materials under such harsh process conditions can also achieve perfect mixing in the conical spiral belt vacuum mixing/drying machine of Chengxin Company.

6、 Low shear force spiral belt mixing
Using a low shear force spiral stirring blade, gently mix materials at low speed and low energy consumption. The intensity and mixing time of the mixture are relatively low.

7、 Suitable for viscous materials
Under the action of friction and pressure generated between material particles during mixing, even highly viscous materials can be separated and effectively mixed.

8、 Different material loading rates
The filling rate of the conical spiral belt mixing/drying machine is 30% -100% of the effective working volume, and consistent results can be obtained for mixing and drying with different loading amounts within this range.

9、 Sealed cleaning design
The conical spiral belt vacuum mixing/drying machine itself is a fully enclosed design, and all connecting components including feeding and discharging are fixed, which can meet material and environmental safety requirements.
