Vacuum freeze dryers are widely used in medicine, pharmaceuticals, biotechnology, chemicals and food.
I. Application in medicine
Freeze drying technology can be used to preserve various organs such as blood, arteries, bones, skin, cornea and nerve tissue for a long time. Cells are not destroyed during freeze drying, and the organism can be revived after rehydration. For example, freeze-dried bones can be stored at room temperature or in a refrigerator for up to 2 years.
II. Pharmaceutical field
Freeze drying of medicines includes Chinese medicine and Western medicine.
1. Freeze drying of Western medicine: Freeze drying of Western medicine has been developed to a certain extent in China, but there are not many varieties of freeze-dried medicines at present, and the product price is high.
2. Freeze drying of Chinese medicine: At present, some freeze-dried Chinese medicines include freeze drying of a small amount of Chinese medicinal materials such as ginseng, deer antler, yam, cordyceps, etc. A large number of Chinese patent medicines have not yet adopted freeze drying technology. For this reason, there is still great potential for research on freeze drying technology and products of Chinese medicine in my country.
Ⅲ. Biotechnology
Freeze drying includes the production of serum, plasma, vaccines, enzymes, antibiotics, hormones and other drugs; biochemical inspection drugs, immunological and bacteriological inspection drugs; long-term preservation of blood, bacteria, arteries, bones, skin, cornea, nerve tissue and various organs.
Ⅳ. Chemical industry
Ultrafine powder functional materials, such as optical fibers, superconducting materials, microwave dielectric materials, magnetic powder and catalysts that can accelerate reaction engineering.
Ⅴ. Food field
It is used to maintain the color, aroma, taste and nutritional components of food and freeze-dry coffee, seasonings, meat, seafood, fruits and vegetables that can be quickly rehydrated. This excellent performance is particularly outstanding in convenient fast food, showing a strong development momentum. For example, about 50% of Japan's convenient foods are freeze-dried foods.
Vacuum freeze dryers have a wide range of applications and a trend of continuous innovation. By continuously introducing new technologies, innovative designs and improving system performance, it will further promote the expansion of its application areas and the prosperity of the market.
