1. Summary of vacuum dryer.
SZGSeries double cone vacuum dryer is a new generation of drying equipment developed by our company in combination with the same domestic product technology. It has two elastic connection modes of belt and chain, so the equipment runs smoothly. The two ends of the shaft are machined by the large boring machine after welding, which fully ensures the good concentricity of the two axes. Thick steel (stainless steel) plates are used inside and outside the shell to ensure stable operation under vacuum and high pressure. Both the heat medium and vacuum system adopt reliable rotary joint of American technology. As a professional drying equipment manufacturer,We serve hundreds of times per year.,Our products range from high temperature heat conducting oil to heat medium, medium temperature steam and low temperature hot water.
Vacuum dryer
Two.SZGSeries double cone vacuum dryer features:
A higher drying rate can be obtained at lower temperatures. The material is closed and dry, and the material and environment will not be polluted. The thermal efficiency is high. Recoverable solvent. The material can be dried to a very low moisture level. The structure is simple and the cleaning is easy. It is difficult to accumulate material on the rotary wall. Not continuous operation, slow drying speed. The effective heating area is small and difficult to scale up.
Three.SZGApplication scope of series double cone vacuum dryer.
It is suitable for the concentrating, mixing, drying of powdery, granular and fiber materials in chemical, pharmaceutical and food industries, and for the materials which need to be dried at low temperature (such as biochemical products, etc.). It is more suitable for the drying of oxidizable, volatile, heat sensitive, strong stimulation, toxic materials and materials that do not allow to destroy crystals.
Four. The working principle of vacuum dryer.
Heat energy in sealed interlayer(Such as hot water, low pressure steam or heat transfer oil.)The heat is passed through the inner shell to the dried material.
Driven by power, the tank rotates slowly, and the materials in the tank are mixed continuously, so as to strengthen the drying.
The material is in vacuum, and the vapor pressure decreases to make the surface water of the material.(solvent)Saturated and evaporated and discharged by vacuum pump in time. Water content inside the material(solvent)Continuous osmosis, evaporation, discharge to the surface, the three processes continue, materials in a very short time to achieve drying purposes.
