Technical Field
[0001] The invention relates to the technical field of purification devices, in particular to membrane filtration equipment and a method for purifying walnut protein peptides. Background Art
[0002] Walnut protein peptides are generally purified by membrane filtration and ultrafiltration. Walnut protein peptide ultrafiltration is a technology that uses the screening principle of semi-permeable membranes to separate, purify and concentrate walnut protein peptides according to the different sizes and shapes of walnut protein peptide molecules.
[0003] In the prior art, walnut protein peptides need to be filtered in advance when being purified. Since the walnut protein peptides are directly obtained from the last discharged liquid, ultrafiltration purification is also required. However, traditional membrane filtration equipment has problems such as easy clogging of the membrane components, high cleaning frequency, and insufficient transmembrane pressure difference control accuracy. Residual lipids and colloidal substances are easy to contaminate the subsequent ultrafiltration membrane surface, further affecting the purity of the target product. To this end, the present invention provides a membrane filtration device and method for purifying walnut protein peptides. Summary of the Invention
