Industrial Vacuum Dryer

Industrial vacuum dryers are low-temperature drying equipment that heats materials under vacuum conditions. Common types include double cone rotary vacuum dryers, single cone spiral vacuum dryers, and vacuum belt dryers.

The working principle of an industrial vacuum dryer is to reduce the pressure around the liquid in a vacuum, thereby lowering the boiling point of the liquid and increasing the evaporation rate to achieve rapid drying. This makes it particularly suitable for drying heat-sensitive, easily decomposed, and easily oxidized substances.

Drying under low pressure results in low oxygen content, preventing oxidation and deterioration of the dried material, and is suitable for drying flammable and explosive hazardous materials.

It can vaporize moisture in materials at low temperatures, making it easy to dry heat-sensitive materials.

It can recover valuable and useful components from the dried material; and it can prevent the emission of toxic and harmful substances from the dried material, making it an environmentally friendly "green" drying method.

Industrial vacuum dryers, due to their ability to operate in low-temperature, low-oxygen environments, have a wide range of applications, especially suitable for processing high-value materials sensitive to heat and oxygen. This equipment is widely used in research and application fields such as biochemistry, chemical pharmaceuticals, medical and health care, agricultural research, and environmental protection, for powder drying, baking, and sterilization of various glass containers. It is particularly suitable for the rapid and efficient drying of heat-sensitive, easily decomposed, easily oxidized substances and items with complex compositions.

1. Drying Main Chamber: Stainless steel sealed pressure-bearing cylinder/box, with a sealed door equipped with a high-temperature resistant vacuum sealing ring.

2. Heat Exchange Jacket/Heat Exchange Plate: A heat-conducting medium is introduced into the chamber jacket to provide uniform heating for the material.

3. Vacuum Unit: Vacuum pump, buffer tank, vacuum pipeline, vacuum pressure gauge, vacuum regulating valve.

4. Condensation Recovery System: Condenser, cooling water circulation unit, solvent collection and storage tank to recover volatile organic solvents.

5. Insulation Structure: An outer layer of aluminum silicate insulation layer on the chamber surface to reduce heat loss and lower energy consumption.

6. Material Carrying Mechanism: Stainless steel tray, material trolley, rake-type stirring shaft (equipped on stirring-type models).

7. Pressure Relief and Gas Inlet Assembly: Vacuum pressure relief valve, nitrogen inlet for smooth vacuum breaking after drying.
