Description

Technical Field

[0001] The utility model relates to the technical field of desalination, and more specifically to a salted duck egg white membrane ultrafiltration desalination device. Background Art

[0002] In the process of producing salted duck eggs, some duck eggs are damaged after being pickled. These duck eggs cannot be sold as salted duck eggs, and the egg white and egg yolk need to be separated and processed. Since the egg white of the separated duck eggs contains a relatively high salt content, the salted duck egg white needs to be processed to reduce the salt content before subsequent processing. Ultrafiltration desalination is a commonly used process method. Usually, the salted duck egg white is pretreated and then filtered through an ultrafiltration membrane to isolate the salt and other soluble substances therein, thereby achieving the effect of desalination. The ultrafiltration desalination device plays a key role in the salted duck egg processing production line, helping manufacturers to control and improve product quality.

[0003] In the existing salted duck egg white membrane ultrafiltration desalination device, during the pretreatment process, some filtration units have poor filtration effects and fail to effectively remove impurities, sediments or suspended matter in the salted duck egg white, causing these impurities to enter the ultrafiltration tube. The impurities or particulate matter in the salted duck egg white can easily cause blockage and contamination of the ultrafiltration membrane, affecting the normal operation and desalination effect of the ultrafiltration membrane, resulting in unsatisfactory product quality. In addition, some filtration units are inconvenient to clean and maintain, which will also reduce the filtration efficiency of the salted duck egg white and affect subsequent processing.
