Vacuum drying is to put the material in a sealed chamber, then heat the material under low pressure to make the water in the material vapored under lower temperature to get dried product.
Technology Advantage:
1.it is very good for the drying of temperature sensitive material because the drying is finished under lower temperature.
2.it is very good for the drying of oxygen sensitive material because the drying is finished under oxygen isolated chamber.
3.the drying is more effective because the water is more easy to be evaporated under vacuum condition.
4. better drying quality because no pollution in the drying, no overheating, no oxidization
5.convenient for the collection and treatment of the volatiled elements in the drying, so it is suitable for the drying of material with volatile matter, toxin substance etc.
6. energy saving because it has higher drying efficiency and can take use of low temperature heat
