4、 LDG Cone Spiral Belt Vacuum Drying Machine 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 of the same specifications（Double cone rotary vacuum dryer）3-5 times that of the double cone rotary vacuum dryer, with a loading capacity twice that of the double cone rotary vacuum dryer, and a relative efficiency improvement of 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、 LDG cone-shaped spiral belt vacuum dryer with 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. Even under harsh process conditions such as adding a small amount of material to a large batch, it can be perfectly mixed in a conical spiral belt vacuum mixing/drying machine.

6、 LDG Cone Spiral Belt Vacuum Drying Machine with Low Shear Force Spiral Belt Stirring

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、 LDG cone-shaped spiral belt vacuum dryer is 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 of LDG conical spiral belt vacuum dryer

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、 Sealing and Cleaning Design of LDG Cone Spiral Vacuum Drying Machine

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.
