High quality automatic vertical packing machine

The working principle of vacuum freeze dryer： Vacuum freeze dryer is designed for the current existing conventional vacuum dry operation and oven, to transform and upgrade, mainly by the refrigeration system and vacuum system consists of two parts. The use of vacuum dry explosion principle, through the fine temperature of the material frozen to its pin point temperature, so that the moisture in the material into the state of ice, and then in a higher vacuum environment, by heating the material, the ice directly sublimated into hydropathy gas, and then the water vapor condenser in the vacuum system will be water vine gas net condensation, so as to achieve the purpose of material dehydration drying.

The application of vacuum freeze drying technology is very wide, as long as the substances that contain water, non-toxic and non-corrosive can be made into freeze dried products by using vacuum freeze drying technology to achieve the purpose of long-term storage. Vacuum freeze-drying technology is applied to food and pharmaceutical industries, and the products processed with this technology are called freeze-dried food (FD food). Such as meat, poultry, eggs, aquatic products, vegetables, fruits and so on can be made into freeze-dried food. Freeze-drying technology is also used in biopharmaceutical industry, medical industry, health care industry, etc.
