Commercial Fruit Vacuum Freeze Drying Machine

1.- Freeze Drying Equipment Fruit Freeze Drying Machine Strawberry Freezing DryerFreeze drying is to freeze the water in the materials into a solid by freezing, and then sublimate the solid water ice into water vapor by the vacuum and light heating, so as to achieve the purpose of dehydration.Compared with the heating drying method, freeze drying has many advantages, such as low volatile loss, no preservative, keeping the active ingredients in the material. Therefore, freeze-drying technology is widely used in pharmaceutical, food, scientific research and other fields.Generally speaking, freeze-drying machine is mainly composed of refrigeration system, vacuum system, heating system and control system.Features & Advantages Of Freeze Drying Machine:*Protects many heat sensitive substances in the materials.*When drying at low temperature, the loss of some volatile components in the materials is very small.*In the freeze-drying process, the growth of microorganisms and the role of enzymes can not be carried out.*The volume is almost unchanged and the original structure is maintained.*The surface hardening of the material will not be caused because the moisture in the material exists in the form of ice crystal after freeze drying.*The materials is loose, porous and spongy after freezing dried, so can dissolve quickly and completely, and almost immediately returns to its original shape.*Since drying is carried out under vacuum, there is little oxygen, so some easily oxidized substances are protected.*Freeze drying can remove more than 95% ~ 99% of moisture, so that the dried products can be preserved for a long time without deterioration.*Because the material is in the freezing state and the temperature is very low, so the requirement of heat source is not high. 2.-Applications of Commercial Fruit Vacuum Freeze Drying MachineFruits:Strawberry,lemon,blueberry,apple,banana,longan,orange,pitaya, mango,hawthorn,blackberry,peach, kiwifruit,dates,peanut,etc.Vegetables:Such as green onions,carrots,cucumbers,beans,ginger,onions,garlic and so on.Aquatic products: Such as shrimp,small and big fish,kelp and so on.3.-Techinical Index of Commercial Fruit Vacuum Freeze Drying MachineModelTSDG-20Control  PLC Working TypeQuick freezingMaterial304Stainless steelDrying area 20m²Charge amount200kgTray size 600/1000/25mmTray quantity34Tray typedisk or meshShelf number 36pcsShelf temperature-55~120ºCwater discharge 12Hours200kgvacuum pumpRotary vane pumpWorking vacuum temperature≤130Paultimate vacuum
