Products Description

Conical Spiral Vacuum Dryer is a kind of high efficient vacuum drying equipment, which combines conical design and spiral mixing technology, and is suitable for drying heat-sensitive, flammable and explosive, organic solvent materials, as well as powder, granule, paste and viscous materials. This equipment is especially suitable for occasions where drying is required at low temperatures and where the quality of the materials in the drying process is highly demanded.

Application areas

uht

- Pharmaceutical industry: drying of active pharmaceutical ingredients to ensure the stability of drug components.
- Food industry: drying food additives and nutrients to protect the quality and safety of food.
- Chemical industry: Processing chemical raw materials and fine chemicals to enhance the stability and quality of products.
- Biotechnology: drying enzymes and proteins to maintain biological activity.
- Ceramic Industry: Ensure the quality and consistency of ceramic powders and materials .

Working Principle:
The conical spiral vacuum dryer heats up and dries the material through the heating jacket and the propeller's internal heat supply, so that the heat supply area reaches 140% of the whole container area. Materials in the conical cylinder forced heating, relative convection, mixing, heat diffusion in the material, so that the material for a full range of irregular reciprocating motion, complete the material with a single screw belt and the cylinder wall surface of the high-frequency heat transfer and exchange, in a short period of time to achieve heating and drying effect.

Structural composition:
Mainly consists of motor, reducer, frame, mechanical seal, metal sintered mesh filter, hollow double-screw belt agitator, cone-shaped cylinder with jacket heating and discharge valve and other components.
