The water content of a substance exists in two ways:


(1) free water, that is, mechanically bound water and physicalized combined water;


(2) Structural water, that is, water that exists in the structure of the material in a chemically bonded manner.


    The process of freeze-drying is mainly to sublimate free water instead of structural water. The method of sublimating free water is to first freeze it into ice, and then directly sublimate the solid ice into a gaseous water vapor in a vacuum.


    Figure 1 is a three-phase diagram of water, OA is the equilibrium curve of water and water vapor, OC is the equilibrium curve of ice and water vapor, and OB is the equilibrium curve of ice and water. As the pressure increases, the melting point of the ice decreases. O is the three-phase equilibrium point. Under this temperature and pressure, the three phases of water coexist.


    Freeze-drying is based on the above principle, and the substance containing a large amount of water is previously cooled down to a solid. The water vapor is then sublimated directly from the solid under vacuum conditions, and the material itself remains in the frozen structure, so that the dried product does not lose the original solid skeleton structure, maintains the original shape of the material, and the product has a pole. Good rehydration.



     Vacuum freeze-drying technique, referred to as freeze-drying, also known as sublimation drying. Widely used drugs, biological products, chemical and food industries. On the heat-sensitive substances such as antibiotics, vaccines, blood products, hormones and other biological tissue enzymes, freeze-drying technology is applied.

Freeze dryer features:


(1) Freeze-drying is carried out at a low temperature, and therefore is particularly suitable for many heat-sensitive substances. Such as protein, microorganisms and the like, will not degenerate or lose biological vitality.

(2) During the lyophilization process, the growth of microorganisms and the action of enzymes cannot be performed. Therefore, the original trait can be maintained.


(3) When drying at low temperatures, some volatile components and heat-denatured nutrients in the material are lost little, which is suitable for the drying of some chemicals, medicines and foods.


(4) Since the drying is carried out in a frozen state, the volume and shape of the product are almost unchanged, and the original structure is maintained, and concentration does not occur. The dried material is porous and spongy. After adding water, it dissolves quickly and completely, and the original trait is almost immediately restored.


(5) Drying under vacuum, the material is in a state of high oxygen deficiency, and the easily oxidized substance is protected.


(6) Drying can exclude more than 95-99% of water, so that the dried product can be preserved for a long time without deterioration.
