At present, the domestic freeze-drying technology basically proceeds under vacuum conditions, and is a method of storing the raw materials in a high vacuum by directly sublimating the frozen raw materials from a solid state into a gaseous state. It needs a long drying time, consumes a large amount of energy, has a low efficiency of water removal, and is expensive in equipment and high in process cost. Therefore, it is one of the main trends in the development of freeze-drying technology to improve the original freeze-drying equipment and process, improve the drying efficiency, and reduce the production cost. The successful development of particle spray freezing technology has been adapted to this trend. It combines the modern refrigeration process with a variety of drying technologies, using its own developed jets to instantaneously contact the raw material liquid with -70 °C gas countercurrently atomized into droplets to achieve rapid freezing of individual particles, forming a Separate frozen particles, then in a fluidized state at -20 °C to achieve a level of drying, will achieve the required particles for secondary air drying, directly remove the water molecules in the material, so that breakthrough in the vacuum Under the conditions of freeze-drying this limitation, the drying time is shortened, the cost is greatly reduced, and the moisture in the raw material liquid can be taken out. The successful development of this technology will signify that the research on freeze-drying technology in China has already taken place in the world. Forefront.
Single-particle spray freeze-drying technology has been successfully developed
The new type of freeze-drying technology independently developed by Beijing Nino Biotechnology Co., Ltd.: Single-particle spray freezing technology has been successfully developed, and related equipment will meet with customers in early August.
