The ZGS series double cone vacuum dryer is a new generation drying device developed by our company in combination with similar domestic product technology. It has a two-stage elastic connection method of belt and chain, so the equipment runs smoothly. The two end shafts are processed by a large boring machine after welding, which fully ensures the good concentricity of the two shafts. The shell is made of thick steel (stainless steel) plates both inside and outside to ensure stable operation under vacuum and high pressure. Both the heat medium and vacuum system use reliable American technology rotary joints. As a professional manufacturer of drying equipment, we serve our customers with over a hundred units per year. Our products range from high-temperature heat transfer oil as the heat medium, medium temperature steam, and low-temperature hot water.

characteristic:

• Can achieve higher drying rates at lower temperatures.
• The material is sealed and dry, and both the material and the environment will not be contaminated.
• High thermal efficiency.
• Recyclable solvents.
• The material can be dried to a very low moisture content.
• The structure is simple, easy to clean, and the rotating wall is not prone to material accumulation.
• Cannot work continuously, slow drying speed.
• The effective heating area is small and difficult to scale up.

Scope of application: Suitable for the concentration, mixing, drying of powders, granules, and fibers in industries such as chemical, pharmaceutical, and food, as well as materials that require low-temperature drying (such as biochemical products). It is more suitable for drying materials that are prone to oxidation, volatilization, heat sensitivity, strong irritation, toxicity, and materials that do not allow crystal destruction.
