Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a food inspection and filtering device. Background Art

[0002] For food testing, the dissolution method is often used to obtain food ingredients. In the prior art, the filtration speed is slow by using gravity to make the solution flow naturally, because the precipitation of food residues will gradually clog the mesh of the filter, thereby reducing the solution penetration rate. If squeezed by external force, the speed of solid-liquid separation can be increased, but it will also cause the sample residue to clog the filter mesh more densely, making it inconvenient to clean the filter later.
