Vacuum freeze-drying technology has a wide range of applications in the fields of bioengineering, pharmaceutical industry, food industry, material science and deep processing of agricultural and sideline products.
The freeze-drying of medicine includes western medicine and traditional Chinese medicine. Freeze-drying of Western medicine has been developed in China, and many large pharmaceutical factories have freeze-drying equipment. In terms of injections, the freeze-drying process is used more often, which improves the quality and shelf life of medicines and brings benefits to both doctors and patients. There are not many varieties of freeze-dried medicines, the product price is high, and the drying process is not advanced. In terms of Chinese medicine, it is limited to the freeze-drying of a small amount of Chinese herbal medicines such as ginseng, velvet antler, Chinese yam, and cordyceps sinensis. A large number of Chinese patent medicines have not yet adopted the freeze-drying process, which is far from abroad. Japan launched the "Chinese medicine western system" a few years ago, which changed the method of brewing traditional Chinese medicine, solved the tradition that traditional Chinese medicine cannot be made into injections or tablets, and solved the problem that traditional Chinese medicine cannot cure acute diseases. Therefore, the freeze-drying process of traditional Chinese medicine in China And product research has great potential to be tapped.
In the field of biotechnology products, freeze-drying technology is mainly used in the production of drugs such as serum, plasma, vaccines, enzymes, antibiotics, hormones; biochemical inspection drugs, immunology and bacteriology inspection drugs; blood, bacteria, arteries, bones , Long-term preservation of skin, cornea, nerve tissue and various organs.
Equipment status and development
The application of freeze-drying technology and equipment are inseparable. So far, the forms of freeze-drying equipment are mainly divided into two types: intermittent and continuous. The scale of the equipment ranges from less than one square meter to tens of square meters. .
Intermittent freeze-drying equipment
Intermittent freeze-drying equipment is suitable for multi-variety small batch production, especially in the food field is suitable for seasonal food production. With single-machine operation, if one device fails, it will not affect the normal operation of other devices. Intermittent freeze-drying equipment is convenient to control the requirements of heating temperature and vacuum degree at different stages when materials are dried. Equipment manufacturing and maintenance are easy to carry out. However, since loading, unloading and starting operations take up more time, the equipment utilization rate is low and the production efficiency is not high.
