Vacuum freeze-drying technology, also known as freeze-drying or sublimation drying, is a method of pre freezing water containing materials and then sublimating them in a vacuum state. After freeze-drying, the original biological and chemical properties of the item remain basically unchanged, making it easy to store for a long time. After adding water, it can be restored to its original form before freeze-drying and maintain its original biochemical properties. Therefore, freeze-drying technology has been widely applied in fields such as chemical industry, biological products, and food freeze dryers
