Vacuum lyophilizer machine is currently using the most advanced technology for food dehydration processing in the world. It makes hydrous materials frozen in the low temperature status, then under the vacuum condition, it adopts thermal radiation method for heating, to sublimate ice to gas directly. After the moisture comes out, it uses ice-condenser (cold trap) and vacuum device to dehydrate the water content. Vacuum lyophilizer machine has widely application, such as for chemical products, biologics, health product, herbs, agricultural products (meat, pouty, egg, sea food, vegetables and fruits and etc.) The vacuum lyophilizer machine uses high automatic control with time and temperature and adjustable operation. The vacuum lyophilizer machines will preserve food by abruptly drop the temperature in a vacuum chamber to below zero and then by gradually raising it. The water in food will rapidly freeze then slowly evaporate, which helps better preserve the texture, flavor, and nutrients in food.
