vacuum freeze dryer for food
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 freeze dried 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.
