Vacuum freeze-drying technology, also known as sublimation drying, is a method in which water-containing materials are frozen in advance, and then the moisture is sublimated under vacuum. Freeze-dried items have basically the same original biological and chemical properties, and are easy to store for a long time. After adding water, they can be restored to the state before freeze-drying and can maintain their original biochemical properties. Therefore, freeze-drying technology is widely used in the fields of medicine, food, chemical industry, biological products and so on.
Home freeze dryer is a small vacuum freeze dryer. It is suitable for home use and small amount of freeze-dried use. It is widely used in freeze-drying of fruits, vegetables, meat, Chinese herbal medicines, health care products, etc. It is a trend that freeze dryers are developed from specific uses to households. Freeze-dried food and medicinal materials are easy to be stored for a long time, which can retain the taste, nutritional content and shape of the original material to the greatest extent.
