The basic principle of freeze - drying is based on the three - state variation of water. Water has three states, solid, liquid and gaseous. When the water in the triple point (temperature of 0.01 ℃, the water vapor pressure is 610.5 Pa), water, ice and water vapor can coexist and balance each other. In the high vacuum state, using the sublimation principle, the moisture in the pre-frozen materials can be directly sublimated into water vapor to be removed without the melting of ice, so as to achieve the purpose of freeze drying.

Freeze-dried products are spongy, non-drying, excellent rehydration, with very little moisture, and can be stored and transported at room temperature for a long time after the corresponding packaging. Vacuum freeze-drying has been widely used in medicine, biological products and food because of its incomparable advantages over other drying methods. Serum, strains, Chinese and western medicine and other biological products are mostly bioactive substances. Vacuum freeze-drying technology also provides a good solution for the preservation of biological activities.

Freeze-drying is a technology that USES the principle of sublimation for drying. It is a process in which the dried substances are rapidly frozen at low temperature and then the frozen water molecules are directly sublimed into vapor and escaped in an appropriate vacuum environment. The product of freeze-drying are referred to as freeze-dried (lyophilizer), the process is called freeze-dried (lyophilization). The substance is always at low temperature (frozen state) before drying, and ice crystals are evenly distributed in the substance. The process of sublimation will not be concentrated due to dehydration, and the side effects of foam and oxidation caused by water vapor are avoided.

The dry substance is like a dry sponge with a porous shape, the volume is basically unchanged, and it can be easily dissolved in water and restored to its original state. To prevent, to the greatest extent, the physical, chemical and biological degeneration of dry matter. Freeze-dryer is composed of refrigeration system, vacuum system, heating system, electrical instrument control system. The main components are drying box, condenser, refrigerating unit, vacuum pump, heating/cooling device, etc.

Its working principle is to freeze the dry goods to the temperature below the three-phase point, and then sublimate the solid water (ice) in the goods directly into water vapor under the vacuum condition, and remove it from the goods, making the goods dry. After pre-treatment, the materials are sent to the quick-freezing warehouse for freezing, and then sent to the drying warehouse for sublimation and dehydration, and then packaged in the post-treatment workshop. The vacuum system establishes low-pressure conditions for the sublimation drying chamber, the heating system provides sublimation latent heat to the materials, and the refrigeration system provides the required cooling capacity to the cold trap and drying chamber.
