Service-oriented freeze dryer
Freeze Dryer With the continuous development of freeze-drying technology and freeze dryer technology, freeze-drying has been more and more widely used in the development of sterile formulations. The freeze-drying process is the most critical process in the entire freeze-dried aseptic process. The freeze dryer is the most critical core equipment. Freeze-drying process is a process, how to make freeze-dried products, focused on the freeze-drying technology and freeze dryer technology.
The freeze-dryer has excellent performance and can make the moisture in foods to be directly sublimated and dried under the condition of slurry and vacuum without the evaporation of the liquid. It can preserve the original color, smell, taste and shape of foods to the maximum extent. The original nutrients and active substances are rarely destroyed, and the rehydration is rapid. There is no need to use preservatives again. After drying, the products are popular in international markets. Type Food Freeze Dryer The energy-saving type food freeze-dryer mainly includes a quick-freezing warehouse for material freezing, a drying warehouse for sublimation and dehydration, and auxiliary systems such as refrigeration, vacuum, and heating.
In order for China's drying technology to catch up with the international advanced countries, there are many things to do, but the close integration between the academic and industrial circles is one of the most important factors. China must develop from a large dry country to a dry one, and it is necessary to further strengthen basic theoretical research and lay a solid foundation for applied research and application development. Technically, it is necessary to strengthen the degree of automation, testing techniques, manufacturing processes, and design of materials and materials. .
The survey found that in the food processing industry, freeze dryer equipment is often used, and there are also many manufacturers of freeze dryers on the market, which makes the industry more competitive. However, it is also seen that some people are not aware of the competitive performance of the freeze dryer industry. Some of the answers were obtained by consulting some of the factory's staff.
From the perspective of factory workers, the freeze dryer industry is highly competitive. From the content point of view, there are several performances. First, competition in freeze dryer performance. Some large-scale mechanical companies have mastered the core technology of freeze dryers, making the freeze dryer equipment quality and performance. For example, the freeze dryer produced by Beijing Songyuan has good performance and has been highly evaluated by customers. Second, the price of freeze dryers competes. Some companies have introduced price reduction sales strategies in order to increase sales of freeze dryers. Of course, price is the main reference factor for customers to buy products. Third, the competition provided by the manufacturers. Some manufacturers help customers provide personalized customized services, while also providing free maintenance services, won the industry's praise.
With the development of society, freeze dryers are used in many places. The use of freeze dryers is very extensive, and it brings us a lot of help, so it is very popular. Today we have come to understand the freeze drying. Machine processing technology and working principle, we can learn together.
Freeze-drying machine is a freeze-drying process that plays a key role in the manufacture of certain biological products and pharmaceuticals. For example, the measles vaccine and the BCG vaccine should be valid for only 3 months before they are freeze-dried. However, the BCG vaccine safety test takes 2 months to complete. The lyophilization process kept the viable counts of BCG remaining at an acceptable level after being stored for 4 to 5 years. The freeze-drying process biopharmaceuticals are mainly used in the production of biological, biochemical products, Chinese medicine injection products and heat-labile antibiotic products.
The amount of water vapor in the compressed air is determined by the temperature of the compressed air: by keeping the pressure of the compressed air essentially constant, lowering the temperature of the compressed air can reduce the water vapor content in the compressed air, while the excess water vapor condenses. Become liquid. Freeze dryers use this principle to use refrigeration technology to dry compressed air. Therefore, the dryer has a refrigeration system. The refrigerating system of the freeze dryer belongs to the compression type refrigeration and consists of four basic components such as a refrigerating compressor, a condenser, an evaporator, and an expansion valve. They are connected by pipelines and form a closed system. The refrigerant continuously circulates in the system. The state changes and exchanges heat with the compressed air and the cooling medium.
