The vacuum freeze-drying industry in the dry subdivision industry has made considerable progress in the past ten years. Life science research: antibodies, proteins, tissues, microbiology research, etc., so a large number of vacuum freeze-drying applications to the field of bio-pharmaceuticals. A large number of pharmaceutical industry vacuum freeze-drying preparation of vaccines, antibiotics and so on. In the field of health care products, a large number of freeze-dried health products have been active in the health care products market, such as freeze-dried Chinese caterpillar fungus, freeze-dried sea cucumber, freeze-dried antler, and freeze-dried Dendrobium.
Mr. Ye Minghui, deputy general manager of Bo Medical, said: “The vacuum freeze dryer needs to be pre-frozen in the product box. The pre-freezing process is critical and determines the dry quality of the product. After pre-freezing, the product will be vacuumed and heated. In order to remove the moisture of the product, the heating temperature during the drying process should not be too high. After the drying is completed, the nitrogen-filled tamponade or vacuum packing is required. The vacuum freeze-dried product can maintain the original physical and chemical properties."
At present, China's vacuum freeze-drying equipment industry has begun to enter a more mature stage of development, has been able to better meet the actual needs of users in various fields, and in the price is only less than half of the same foreign products, which makes our country vacuum freeze-drying Equipment in the market competition has an obvious price advantage over imported equipment. Any one process or several processes together may become the “bottleneck†of the vacuum freeze-drying process. It depends on the design of the freeze-dried equipment, the operating conditions, and the materials to be dried. feature. Only at the same time improve the heat transfer, mass transfer efficiency, increase the surface area per unit volume of freeze-dried material, can achieve faster drying rate.
At present, China's vacuum freeze-drying equipment industry has begun to enter a relatively mature stage of development, although there is still a certain gap between and developed countries, but overall, the prospects for the production of vacuum freeze-drying equipment companies are very impressive, but it is undeniable that the investment costs Also high, not many companies must go in the direction of the trend of development, strengthen the application of vacuum freeze-drying equipment, promote the development of the domestic drying equipment industry.
