Vacuum Freeze Dryer

Introduction

Vacuum freeze-drying technology is widely applied in biological engineering, pharmaceutical industry, food industry, materials science and deep processing of agricultural and sideline products.

Applying the principle of sublimation for drying. Rapid freezing of the material is achieved in low temperature , and then in a suitable vacuum environment the frozen water molecules will be directly sublimated into water vapor and then escape.
The product obtained by drying is called lyophilisate and this process is called lyophilisation.

The material is always in the low temperature (frozen state) before drying, and the ice crystals are evenly distributed in the material. The sublimation process will not be concentrated due to dehydration, thus avoiding side effects such as foam and oxidation caused by water vapor. Dry matter was dry sponge porous, the volume is basically the same, very easy to dissolve in water and restitution. To the greatest extent to prevent physical and chemical and biological aspects of denaturation.
The freeze dryer is composed of a refrigeration system, a vacuum system, a heating system and an electrical instrumentation control system. The main components is oven, condenser, refrigeration units, vacuum pumps, heating / cooling devices. Its working principle is to make the material be frozen below a certain temperature, and then under the conditions of the vacuum the solid state of the water (ice) is directly sublimated into water vapor and discharged out to get dry items.

As the saying goes, there is no perfect technology. The main disadvantage of vacuum freeze-drying technology is its high cost. Because it needs vacuum and low temperature conditions, the vacuum freeze dryer must be equipped with a vacuum system and a low temperature system, so the investment cost and operating cost are relatively high. application 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 medicines includes two parts: Western medicine and Chinese medicine. Freeze-drying of western medicine has developed to a certain extent in China, and many larger pharmaceutical factories have freeze-drying equipment. In terms of injections, freeze-drying processes are used more, which improves the quality and shelf life of medicines, and brings benefits to both doctors and patients. However, there are not many varieties of freeze-dried medicines, the product prices are high, and the drying technology is not advanced. In terms of traditional Chinese medicine, it is currently only limited to the freeze-drying of a small amount of Chinese medicinal materials such as ginseng, velvet antler, yam, and cordyceps. A large number of Chinese patent medicines have not yet adopted the freeze-drying process, which is far behind foreign countries. A few years ago, Japan launched the "Western Preparation of Chinese Medicines", which changed the boiling method of Chinese medicines, solved the traditional Chinese medicine cannot be made into injections or tablets, and also solved the problem that Chinese medicines do not cure acute diseases. Therefore, the freeze-drying process of Chinese medicines in my country And product research has great potential to be tapped. In the field of biotechnology products, freeze-drying technology is mainly used for the production of drugs such as serum, plasma, vaccines, enzymes, antibiotics, hormones; biochemical inspection drugs, immunology and bacteriological inspection drugs; blood, bacteria, arteries, bones , Skin, cornea, nerve tissue and various organs for long-term preservation.
