AI Technical Summary
In the existing technology for filtering aseptic fructose diphosphate sodium powder, the centrifugation effect is poor in the middle area of the filter membrane, which easily forms a local sticky filter cake, increasing the filtration resistance. In addition, the lack of agitation effect in the filtration zone leads to impurity residue, making it difficult to maintain a sterile environment.
The system employs a multi-stage fine filtration device. The drive mechanism drives the cam on the lifting shaft to rotate and lift synchronously. The oscillating grinding head crushes the sticky particles, and the agitation of the cam prevents the accumulation of impurities, ensuring a sterile environment.
This effectively avoids increased filtration resistance and impurity residue, maintains the sterility and purity of the filtration process, and ensures the quality of the preparation of aseptic fructose diphosphate sodium powder.
