Commercial Freeze Drying Equipment

Commercial Freeze Drying Equipment

1、 Product Overview

The basic principle of freeze drying is based on the three-state change of water. Water has a solid state, a liquid state, and a gas state. The three states can be transformed and coexisted with each other. When water is at the three-phase point (temperature is 0.01 ℃, water vapor pressure is 610.5pa), water, ice, and water vapor can coexist and balance each other. In the high vacuum state, commercial freeze drying equipment uses the sublimation principle, the water in the pre-frozen material is directly sublimated into water vapor without melting the ice, so as to achieve the purpose of freeze-drying. The lyophilized products are spongy, have no dry shrinkage, have good rehydration, and have little water content. After corresponding packaging, they can be stored and transported at room temperature for a long time. Since vacuum freeze-drying has the advantages of other drying methods, it has been more and more favored by people since its advent and has been widely used in medicine, biological products, and food. Biological products such as serum, strains, and traditional Chinese and Western medicine are mostly bioactive substances. Vacuum freeze-drying technology also provides a good solution for preserving bioactivity.

2、 Product application

Commercial freeze drying equipment is widely used in bioengineering, the pharmaceutical industry, food industry, material science, and deep processing of agricultural and sideline products. Drug freeze-drying includes Western medicine and traditional Chinese medicine. Western medicine freeze-drying has been developed in China. Many large pharmaceutical factories have freeze-drying equipment. In terms of injections, freeze-drying process is used more, which improves the drug quality and storage life, and brings benefits to both doctors and patients. However, at present, there are few varieties of freeze-dried drugs, the product price is high, and the drying process is not advanced. In terms of traditional Chinese medicine, at present, it is only limited to the freeze-drying of a small amount of traditional Chinese medicine such as ginseng, pilose antler, yam, and Cordyceps Sinensis. 

A large number of Chinese patent medicines have not adopted the freeze-drying process, which is far from abroad. Japan launched the "Western preparation of Chinese medicine" a few years ago, which changed the boiling method of traditional Chinese medicine, solved the tradition that traditional Chinese medicine can not be made into injections or tablets, and also solved the problem that traditional Chinese medicine does not cure urgent diseases. Therefore, the research on freeze-drying technology and products of traditional Chinese medicine in China has great potential. In the field of biotechnology products, commercial freeze drying equipment is mainly used for the production of drugs such as serum, plasma, vaccine, enzyme, antibiotic,s and hormones; Biochemical inspection drugs, immunological and bacteriological inspection drugs; Long term preservation of blood, bacteria, arteries, bones, skin, cornea, nerve tissues and various organs.
