Vacuum drying equipment SZG double cone vacuum dryer performance characteristics

Vacuum drying equipment SZG double cone vacuum dryer performance characteristics

◎When the oil is heated. Using automatic constant temperature control. Can dry biochemical products

◎And mineral raw materials, the temperature can be between 20 ~ 160oC.

◎High thermal efficiency, more than 2 times higher than that of ordinary ovens.

◎Indirect heating. Material will not be contaminated

Working principle of vacuum drying equipment SZG double cone vacuum dryer

◎Put heat energy (such as hot water, low-pressure steam or heat transfer oil) into the closed interlayer, and the heat is transferred to the dried material through the inner shell.

◎ Driven by power, the tank body rotates slowly, and the materials in the tank are continuously mixed, so as to achieve the purpose of strengthening drying.

◎The material is in a vacuum state, and the vapor pressure drops to make the water (solvent) on the surface of the material reach a saturated state and evaporate, and is discharged and recovered by a vacuum pump in time. The moisture (solvent) inside the material continuously penetrates to the surface, evaporates and discharges three processes, and the material achieves the purpose of drying in a very short time.

Dehumidification of vacuum drying equipment

Vacuum dehumidification and drying equipment: The main parameter controlled by the vacuum dehumidification and drying equipment to quickly evaporate the moisture in the raw materials to achieve rapid drying is the degree of vacuum; the vacuum drying equipment and the dehumidification and drying equipment are put together for testing. The principle is to use the principle of lowering the evaporation point of water at low pressure. The results can show that the vacuum drying equipment can save 70%-80% of the energy consumption. This is mainly because the desiccant of the desiccant drying equipment consumes a lot of energy during the regeneration process. The drying time of vacuum drying is usually 1/5 - 1/6 of other dehumidification drying. Long-term high-temperature drying will cause thermal chemical and physical reactions of raw materials, which will reduce the quality of materials, such as fading and melting index. affect the quality of the waste.
