In recent years, it has become increasingly recognized that freeze-drying technology is not only the best way to preserve perishable food, but also a good means of preserving healthy and healthy food or ingredients without the use of preservatives. With the continuous maturity of food freeze dryer equipment and the expansion of application scope, the demand for freeze-dried food is increasing.

Expert research has found that the instant dumplings obtained by freeze-drying only need to be soaked in hot water above 90~95°C for 8~10min, and the original shape and structure of the dumplings can be maintained. properties and rapid rehydration.
