Purpose: freeze drying is a method of soft drying of substances, in which, before drying, the substance in the liquid composition is subjected to deep freezing (temperature from -50 ° C to -105 ° C), and then placed in a chamber, where, under the action of vacuum and low temperature, the frozen solvent is removed (sublimation). Vacuum freeze drying technology, also called freeze-drying, is a technical method in which samples are pre-frozen and then their moisture is sublimated in a vacuum state. Goods are easier to store for a long time after being freeze-dried. They can be restored to their original state and retain their chemical and biological characteristics after watering. Therefore, freeze drying technology is widely used in medicine, food, chemical industry, biological products, etc.
