With the development of the biological, pharmaceutical, food and health product industries, the vacuum freezing dryer is a vital piece of equipment.
Vacuum freeze drying is an advanced method of material dehydration. It freezes the material in the low temperature and makes the water inside sublimate directly in the vacuum condition. Then it collects the sublimated vapor by means of the condensation, leaving behind a dried product.
