Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a decompression filtering equipment for producing bovine bilirubin. Background Art

[0002] In the technical field involved in the utility model, the vacuum filtration of bovine bilirubin plays a key role in its production process, which is mainly reflected in purification and refining, improving product stability, improving process efficiency, strengthening quality control and enhancing safety. Through vacuum filtration, impurities and by-products can be effectively removed and the purity of bilirubin can be improved, which is crucial to meet the high specifications of the medical and industrial fields. In addition, by removing impurities and moisture, the chemical stability of bilirubin is enhanced, making it less likely to degrade during storage and use. Vacuum filtration can also speed up the filtration speed and shorten the production cycle, thereby improving overall efficiency, reducing production costs and increasing production capacity. In terms of quality control, vacuum filtration ensures that each batch of products can meet the expected quality standards. At the same time, because it is carried out at relatively low temperature and pressure, the safety of the process is also greatly improved, reducing the potential risk of chemical reactions. Therefore, vacuum filtration has important functions and significance for the production of bovine bilirubin.
