Problems solved by technology

However, the above-mentioned patents all have shortcomings such as small specific surface area, low porosity, large mass transfer resistance, and single protein type of the adsorption matrix material, resulting in low adsorption capacity of the material, slow adsorption rate, low protein dissolution rate, and the drive required for separation. High energy consumption, low production efficiency and high production cost

Domestic CN203048837U discloses and reports a kind of batch protein separation and purification device, and this device assembles multiple groups of processing containers, chromatographic columns, and solution collectors after separation side by side, and relies on gravity drive and siphon drive to realize protein separation and integration operations, although The driving energy consumption is reduced, but only relying on gravity and siphon drive makes the production efficiency of the device low, and the device structure is complicated and the preparation cost is high
