Daily application of freeze dryer equipment

Intermittent freeze-drying equipment is suitable for multi-variety and small-volume production, especially in the food scale for seasonal strong food production. In contrast, the specifications of foreign freeze-drying equipment are more than domestic, the equipment is complete, the energy-saving structure is full of enthusiasm, and the continuous freeze-drying equipment has a large production capacity.

Intermittent freeze-drying equipment Vacuum freeze-drying technology has a wide range of monopoly in bioengineering, pharmaceutical property, food property, material science and deep processing of agricultural by-products. Intermittent freeze-drying equipment facilitates the request for heating temperature and vacuum at different stages of drying of the material. In terms of traditional Chinese medicine, it is still limited to lyophilization of a small amount of Chinese medicinal materials such as ginseng, velvet, yam, and Cordyceps sinensis. A large number of proprietary Chinese medicines have not been freeze-dried, and the gap with foreign countries is large.

The tyranny and equipment of freeze-drying technology are inseparable. Up to now, the situation of freeze-drying equipment is divided into two categories: intermittent and continuous. The scale of equipment ranges from less than one square meter to several tens of square meters. . The processing, construction and maintenance of the equipment are easy to carry out. A few years ago, Japan opened the "Western Chinese Medicine" system, changed the preparation of Chinese medicine, solved the tradition that Chinese medicine can not be made into injections or tablets, and also solved the hardship of Chinese medicine to cure diseases. Research on dry processes and products has great potential to be tapped.

The drug is freeze-dried and collected into two parts: western medicine and traditional Chinese medicine.

With the GMP certification, the domestically produced super-medical freeze-drying equipment has entered the stage of ancientization. It has complete functions, reliable work and constant performance. It can be cleaned up at this time (CIP) or steam sterilization (SIP). Various technical indicators can meet the needs of freeze-dried production of biological products and pharmaceuticals. However, due to the fact that the charging, unloading, starting, etc. are used in combination, the equipment monotony rate is low and the production efficiency is not high. Adopting a single machine to dominate, if a device fails, it will not affect the normal operation of other devices. In the past few years, the initial test and dominance of continuous vacuum freeze-drying equipment at home and abroad.

In the scale of biological craftsmanship, freeze-drying technology is mainly used for the production of drugs such as serum, plasma, vaccine, enzyme, antibiotic, hormone, etc.; biochemical search for drugs, immunology and bacteriology for drug testing; blood, bacteria, arteries Long-term preservation of bones, skin, cornea, nerve tissue and various organs.

The status quo and growth of the equipment in the aspect of injection, the freeze-drying process uses more fighting power, advances the ethical quantity of medicine and storage, and brings benefits to both doctors and patients. However, there are few varieties of freeze-dried drugs, the price of the products is high, and the drying process does not advance to the ancestors. The continuation equipment is characterized by the production of products with a single variety and complex production and substantial raw materials, and the production of suitable slurry and granular products. . The continuation device is easy to implement automatic control, which simplifies the manual hegemony and management, and its important shortcomings are high cost. In order to ensure the quality and energy saving of the freeze-dried products, it is often used in combination with freeze-drying equipment and other drying equipment, such as spray freeze-drying equipment. Western medicine freeze-drying has achieved certain growth in China, and many larger pharmaceutical plants have freeze-drying equipment.
