Technical Field
[0001] The present invention relates to the technical field of vaccine production, in particular to an ultrafiltration concentration device for treating vaccine stock solution. Background Art
[0002] In the vaccine production workshop, the virus must go through six major steps, including cultivation, inactivation, purification, concentration, filling, and packaging before it can finally be actually used by people.
[0003] The concentration process has always been taken very seriously. During concentration, it is necessary to pay close attention to the degree of concentration and the threatening problems caused by concentration. The usual solution to this problem is the ultrafiltration concentration process. Usually, this process also represents the first step in separating the product from large pieces of debris, while maximizing product output and quality. In this process, if there is a problem of residual deterioration, the vaccine concentrate is likely to be contaminated on a large scale, leading to fatal problems in product production. At the same time, the concentration process may also be accompanied by a lot of waste and harm to the surrounding ecology. These problems need to be urgently resolved. Summary of the Invention

During the delivery process, the adjustment component can fully adjust the fluid pressure in the feed pipe to reduce residue. When the vaccine concentrate enters the concentration layer, the concentration motor will drive the separator to rotate, thereby causing the vaccine concentrate to centrifuge. The heavier cell membranes and impurity proteins will be separated to the farthest position and discharged to the drain outlet. These materials are then sent to the drainage pipe. The concentrated vaccine concentrate will then be sent to the discharge outlet, and then the discharge outlet will be sent to the discharge pipe.
