Vacuum Freeze Dryer Machine

How does vacuum freeze dryer machine become the "new favorite" of today's food industry? The vacuum freeze-drying technology of freeze-drying machine and freeze-dried food are still in the initial stage in China. However, the further development and huge market demand of China's agriculture, including grain, fruits and vegetables, animal husbandry, aquatic products and aquaculture, will make China's freeze-dried food industry obtain unprecedented development.

The great advantage or prominent advantage of freeze-dried food is that it can be eaten once rehydrated. It is an indispensable "logistics" for modern people with high efficiency and fast pace in life. It is reported that freeze-dried food is particularly popular in some developed countries.

At present, due to the huge demand in the domestic market, it not only provides space for the great development of freeze-dried food in China, but also provides a good opportunity for the processing and appreciation of agricultural and sideline products.

According to experts, freeze-dried food can process most foods and drugs, including all kinds of vegetables, fruits, fish, coffee, tea, traditional Chinese medicine, ginseng, enzymes, serum, strains, biological products, aerospace food, etc.

The vacuum freeze-drying technology of freeze dryer originated in the 1920s and made great progress in the next 20 years. In the 21st century, vacuum freeze-drying technology has attracted more and more attention by virtue of the advantages of other drying methods. In addition to being widely used in the fields of medicine, biological products, food, blood products and active substances, its application scale and field are still expanding.

The basic principle of freeze drying is based on the three state change of water. Water has solid state, liquid state and gas state. The three phases can be transformed and coexisted with each other. When water is at the three-phase point (temperature 0.01 ℃, water vapor pressure 610.5pa), water, ice and water vapor can coexist and balance with each other. In the high vacuum state, using the sublimation principle, the water in the pre frozen material is directly sublimated into water vapor without melting the ice, so as to achieve the purpose of freeze-drying. The lyophilized products are spongy, without drying shrinkage, excellent rehydration and little water content. After corresponding packaging, they can be stored and transported at room temperature for a long time. Since vacuum freeze-drying has the advantages of other drying methods *, this technology has been more and more favored by people since its advent.

Freeze-drying methods are diverse, such as sun drying, drying, drying, spray drying and vacuum drying. However, ordinary drying methods are usually carried out at temperatures above 0 degrees Celsius or higher. The dried products generally have the problems of volume reduction and texture hardening. Most of the volatile components will be lost. Some heat sensitive substances are denatured and inactivated, and some substances even oxidize. Therefore, there are great differences in the properties of the dried products compared with those before drying.
