Vacuum Freeze-drying Equipment 125Freeze-drying EquipmentBasic Principle of Vacuum Freeze-drying：Vacuum freeze drying process:Frozen original material first,insure the condition of vacuum and adequate heating,then the water will be removed from frozen product by sublimate,finished product will maintain frozen state and biological structure.Features of Vacuum Freeze-dried products1. Under the condition of low temperature vacuum drying,keep the natural activity of material2. Natural fresh color,aroma and nutritional value retained shape and texture of fresh product is maintained,concentrated fresh flavor in finished product3. No additives or preservatives are used-finished product is all natural4. Low moisture,lightweight,easy to carry and keep a long shelf life.5. Spongy structure,add water back,easy recovered in short time.Technical data of A series Vacuum Freeze-drying Equipment Standard type for industrialized productionModelA25A50A75A100A125A200Nominal area of heating plates(㎡)255075100125200Max.design vapor condensing capacity（kg/h）57.5115173230280450Operating temperature of heating plates（℃）30-12030-12030-12030-12030-12030-120Normal min. working pressure (Pa)454545454545Evacuating time with empty loading（min.）5810111215Required cooling capacity (KW,-40℃)4585132180217350Max.vapor consumption（0.7mPa）kg/h70135200240290480Installation power (KW)3055688694135Double doors can be designed according to customer's request
