Liquid food desalting device based on static magnetic field

The utility model discloses a liquid food desalting device based on a static magnetic field, and belongs to the technical field of crossing of magnetics and food science. According to the utility model, two independent circulation pipelines are adopted, salt-containing liquid food is guided into one circulation pipeline, and fresh water is guided into the other circulation pipeline, and the salt-containing liquid food and the fresh water flow reversely under the driving by diaphragm membranes, and pass by the perpendicular magnetic field area; the two pipelines have a contact surface in the magnetic field area, and quartz sand filtering sheets and ion exchange membranes are adopted for insulation. The liquid food desalting device provided by the utility model can be used for desalting liquid food with the salt content of 5%-18%, can enable the salt content of raw materials to be reduced by 30%-40% after the treatment for 2-4 hours, is easy and convenient to operate, is easy to assemble and construct, and realizes large-scale desalting treatment for liquid food with high salt content.
