Product Description
The vacuum freezing and drying technology is currently the most advanced dehydrating processing technology in the world. Compared with the commonly used drying method, the freezedried food produced by lyophilizer features long period of quality assurance, good re-hydration nature, good-looking color, good flavor, taste and high content of nutritious components the dried food basically remains unchanged in its volume and shape,looks like sponge and has no shrinking.
Brief introduction
FDG series lyophilizers are consisted of food pre-freezing system, freezing and drying pot, heating system, vacuum system, refrigerating system, material conveying system and control system, etc.
The vacuum system adopts the combination of water-sealed pump and oil-sealed pump. The way of heating is closed water circulation heating. And the condenser is placed inside heating tank besides the heating plates. Of course, it can be customized according to the practical condition, for example, placed above the drying pot.
Application
The vacuum freezing and drying machine can be widely used in various fields, such as vegetables, fruits, condiments, seafood, biological products, medicine, beverage, specimen, etc.
