Industrial freeze dryer
Kemolo company, one of the leading industrial freeze dryer manufacturers and suppliers in China. Our large industrial freeze dryers had been exported to more tham 40 countries in the world. Industrial freeze dryer is composed of refrigeration system, vacuum system, heating system, electrical instrument control system. The main components are drying oven, condenser, refrigeration unit, vacuum pump, heating/cooling device, etc. The working principle is to freeze the dried item to below the triple point temperature, and then directly sublime the solid water (ice) in the item into water vapor under vacuum conditions, remove it from the item, and dry the item. After pre-processing, the materials such as fruit, vegetable, coffee etc are sent to the quick-freezing warehouse for freezing, then sent to the drying chamber for sublimation and dehydration, and then packaged in the post-processing workshop.
The vacuum system establishes low-pressure conditions for the sublimation drying chamber, the heating system provides sublimation latent heat to the material, and the refrigeration system provides the required cold energy to the cold trap and drying chamber. Industrial vacuum freeze dryer adopts radiation heating, and the material is heated evenly; adopts water trap and can realize rapid defrost; adopts vacuum unit, and can realize oil-water separation; adopts parallel centralized refrigeration system, multi-channel cooling on demand, working conditions Stable and energy-saving; using artificial intelligence control, high control precision and easy operation.
Industrial big freeze dryer has excellent performance, which can make the water in the food directly sublime and dry from the solid under the conditions of slurry and vacuum, without evaporation of the liquid. It can preserve the original color, aroma, taste and shape of the food to a large extent, the original nutrients and active substances are rarely damaged, and the rehydration is rapid, no preservatives are needed, and the product is dried by an industrial vacuum freeze dryer. The foods are popular in the market, mainly including quick-freezing warehouses for freezing materials, drying warehouses for sublimation and dehydration, and auxiliary systems such as refrigeration, vacuum, and heating.
