In the process of drying the material, the Szg double cone vacuum dryer greatly improves the drying speed due to the continuous replacement of the heated surface of the material. Moreover, the product is evenly dried, and the material is protected from contamination due to the indirect heating. The entire structure design has no dead ends, easy to operate and easy to clean. The optimized design of the sealing method makes the sealing effect better and the maintenance is particularly convenient.
The drying principle of the Szg double cone vacuum dryer is: the introduction of thermal energy into the sealed interlayer, usually hot water, low pressure steam or heat transfer oil, and heat is transferred to the dried material in the inner shell. Under the power drive, the tank rotates slowly, and the materials in the tank are continuously mixed to achieve the purpose of strengthening drying.
The dry environment is in a vacuum, allowing the material to dry in a short time. The Szg double cone vacuum dryer has high thermal efficiency and is more than 2 times higher than the average oven. This machine is suitable for vacuum drying of powder and granular materials in medicine, food, chemical industry, etc. It is especially suitable for the drying of the following materials: heat sensitive, easy to oxidize, materials that are not allowed to be destroyed by crystals materials for solvent recovery and strong toxic materials.
