Freeze-drying (freeze-drying for short) is a stable process of drying materials. It first freezes the water-containing materials into solids, and then sublimates the water from the solids to the air, and removes the water to preserve the materials in the solution stage. After freezing, 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 liquid solid gaseous process. 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. With the continuous distillation of the solvent, the solid bridges continue to decrease, but the relative position between the two particles will not change until the solid bridges disappear completely.
