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.
Freeze-dried medicines include western medicine and traditional Chinese medicine. China has developed freeze-drying equipment for western medicine, and many large pharmaceutical factories are equipped with freeze-drying equipment. As far as injections are concerned, the freeze-drying process is used more frequently, which improves the quality and shelf life of the medicine and brings benefits to doctors and patients.
There are not many varieties of freeze-dried medicines, the product prices are high, and the drying technology is not advanced. As far as traditional Chinese medicine is concerned, it is limited to freeze-drying of a small amount of Chinese herbal medicines, such as ginseng, velvet antler, yam and cordyceps. Many Chinese patent medicines have not yet adopted the freeze-drying process, which is far from abroad.
Japan launched the "Western Medicine System of Traditional Chinese Medicine" several years ago, which changed the brewing method of traditional Chinese medicine, solved the traditional Chinese medicine cannot be made into injections or tablets, and solved the problem that traditional Chinese medicine cannot cure emergencies. disease. Therefore, research on freeze-drying technology and products of Chinese traditional medicine has great development potential.
In the field of biotechnology products, freeze-drying technology is mainly used to produce serum, plasma, vaccines, enzymes, antibiotics, hormones and other drugs; biochemical testing drugs, immunology and bacterial testing drugs; blood, bacteria, arteries, bones, skin, cornea, Long-term preservation of 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.
