This equipment adopts the core technology of precision manufacturing from Huasheng Company, with a unique single row five tank design. The gearbox meets GMP requirements, and the bearings are precision assembled with liquid ammonia at low temperatures. The parts are precision assembled with low-temperature liquid ammonia and equipped with multi-point temperature control devices inside the tank to ensure that the materials are coated within the golden time. It adopts a triple sealing structure to ensure that there is no oil leakage in extreme environments, completely solving the problem of drug contamination. At the same time, it achieves no dead corner stirring to ensure uniform drug dispersion.
