Freeze-drying (referred to as freeze-drying) is a stable process of drying materials. It freezes the water-containing materials into solids, and then sublimates the water from the solids to the air, removing the water to preserve the materials


The product in the solution stage is frozen by sublimation and desorption, and then the solvent is reduced to a certain extent, thereby preventing the formation of microorganisms or the chemical reaction between the solute and the solvent, so that the product can be stored for a long time and its properties can be maintained. 


The vacuum freeze-drying method is a process of liquid→solid→gas. During the freeze-drying process, the liquid bridges between the solution particles have been frozen into solid bridges. The relative position of the particles has been fixed, and there is no surface tension on the gas-liquid interface between the two particles. 


As the solvent continues to distill, the solid-phase bridge will continue to decrease, but the relative position between the two particles will not change until the solid-phase bridge disappears completely.
