Main application of food freeze dryer:
Vacuum freezing and drying technology is currently the most advanced technology for food dehydration processing in the world. Compared with the commonly used drying method, the freeze-dried food produced with this technology 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. This drying technology can be widely used in process of vegetables, fruits, condiments, aquatic products, biological products, medicine, beverage, exemplar etc.
Main part of food freeze dryer:
FD-FP series vacuum cryogenic drying equipment mainly includes food pre-freezing system, drying bin system, heating system, vacuum system, refrigerating system, material conveying system, medium system, pneumatic system, cleaning and sterilizing system.
