Working Principle of Freeze Dryer
Freeze-drying refers to the method of freezing the water-containing substance into a solid state first, and then sublimating the water directly from the solid state into a gas state under a certain vacuum degree to remove the water and preserve the substance.
The basic principle of freeze-drying is based on the change of three states of water. Water has a solid, liquid and gas state, and the three states can be converted into each other and can coexist.
When water is at the triple point (temperature is 0.01℃, water vapor pressure is 610.5Pa), water, ice and water vapor can coexist and balance each other.
When the pressure is lower than 610Pa, no matter how the temperature changes, the liquid state of water cannot exist.
In a high vacuum state, using the principle of sublimation, the moisture in the pre-frozen material is directly sublimated into water vapor in an ice state and removed without melting the ice, so as to achieve the purpose of freeze-drying.
