  Since the centrifuge in the medical field should be released from the drug, the surface of the centrifuge device must be smooth, flat, and free of dead angles. Therefore, it is necessary to ensure that the sharp corners, corners, and welds of the centrifuge are ground into a smooth transition circle during the manufacturing process. angle. Because of the need to make contact with the drug, the centrifuge needs to be resistant to corrosion, chemical changes or drug adsorption.
  In the pharmaceutical industry, due to stricter requirements on production quality and production safety, the main process equipment for the production of raw materials in centrifuges and other pharmaceutical production fields also has extremely high requirements. In addition to maintaining its own separation characteristics, centrifuges also need to meet the relevant specifications and standards in the medical field. Centrifuges need to consider materials, structures, material input and output methods, safety, labor intensity, control, cleaning or disinfection from the perspective of meeting the requirements of the pharmaceutical production process.


  There are many types of centrifuges.
  According to the purpose of separation, it can be divided into: laboratory medicine centrifuge and industrial medicine centrifuge.
  According to the structure can be divided into: desktop medicine centrifuge and floor-standing medical centrifuge.
  According to the temperature control, it can be divided into: frozen medicine centrifuge and normal temperature medical centrifuge.
  According to the separation component, it can be divided into: a pharmaceutical solid-liquid separation centrifuge and a medical liquid-liquid separation centrifuge.
  Divided by capacity: micro-medicine centrifuge, small-capacity pharmaceutical centrifuge and large-capacity medical centrifuge.
  From the functional point of view, the centrifuge material has strong adaptability, and the appropriate filter medium can be used to separate the fine particles of the millimeter order, and can also be used for the dehydration of the articles, and the articles can be cleaned by the water washing tube. The artificial upper unloading type has simple structure, convenient installation, low cost, easy operation, and can maintain the grain shape of the product. The machine adopts advanced elastic support structure, which can reduce the vibration caused by uneven load and the machine runs smoothly. The entire high-speed structure is concentrated in a closed casing to achieve sealing and avoid contamination of materials.
  The centrifuge has the requirements of cleaning and sterilization when changing batches and changing varieties in production, preventing various pollution sources and avoiding re-contamination. The centrifuge needs to work hard in the aspects of automatic control of the program, human-machine isolation operation, easy cleaning, sterilizable and sterilizable structure, on-line analysis and separation of different traits, and improve the function, control and sterilizing operation level.
  The main accessories of the centrifuge are the rotor and the centrifuge tube. They should be used strictly in accordance with the instructions. Usually, they should be cleaned, disinfected and maintained. If there is obvious crack on the bottom of the centrifuge hole, the bottom of the centrifuge tube or the wall, Can't use it. The rotors of different manufacturers can not be mixed, it should be used together, otherwise it will reduce the life of the rotor and even damage the centrifuge. As long as the centrifuge is carefully maintained, the operating state is observed, the sound is heard, the early diagnosis, and the immediate treatment can make the centrifuge perform at a high efficiency.
