The interaction of the solid, liquid and gaseous state of water.
Under vacuum condition, the lyophilizer uses the principle of sublimation to sublimate the water in the frozen material directly into water vapor in the state of ice without melting ice, thus achieving the purpose of freeze-drying.
Freeze-dried products made by freeze-drying mechanism usually have very low residual moisture, no shrinkage and spongy porous shape, with good rehydration. Packaged products can also be stored and transported for a long time at room temperature.
Freeze-drying machine is widely used in food processing and other fields.
Freeze Drying Advantages
- The freeze-dried material retains its original structure well and will not shrink.
- Since the water in the material exists in the form of ice crystals after pre-freezing, the inorganic salts dissolved in the water are evenly distributed in the material.
- The freeze-drying machine is used to dry materials in the frozen state. The heat source requirements are not high, the room temperature heater can meet the requirements, more energy saving and consumption reduction.
