Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a sampling device used for food detection. Background Art

[0002] During the processing of fluid food, in order to ensure the safety and hygiene of the food, it is necessary to regularly take samples from the food flow trough and send them for inspection. Only food that meets the safety requirements is allowed to flow into the next process for processing or packaging. Sampling and inspection are generally carried out during the transmission process or in storage equipment.

[0003] In the prior art, an open container is inserted into the food flow trough to suck or scoop out part of the fluid. This process involves the cleaning and sanitation of sampling tools and sampling operations, which is very troublesome to control.

[0004] In response to the above problems, the existing patent (publication number: CN221006883U) provides a sampling device for food testing. The sampling shell and the collecting cup are installed inside the food flow groove. A feed port is opened on the side of the sampling shell facing the direction of food flow. An elliptical plug is provided on the inner side of the feed port. Most of the elliptical plug is located outside the sampling shell. A central column is fixedly connected to the inner side of the feed port and the inner side of the elliptical plug. A spring is fixedly connected between the central column and the inner side wall of the elliptical plug. The elastic force of the spring drives the elliptical plug to move along the radial direction of the sampling shell toward the inside of the sampling shell, which is used to solve the problem of the existing sampling mechanism, which uses an open container to be inserted into the food flow groove to absorb or scoop out part of the fluid. This process involves the cleaning and hygiene of the sampling tools and sampling operations, which is very troublesome to control.

[0005] In response to the above problems, existing patents have provided solutions, but the removal and transportation through external equipment will inevitably be separated from other impurities such as air, which will affect the sampling and detection to a certain extent. In addition, before sampling liquid food, stirring blades are usually used for pre-mixing and detection, which can easily cause excessive stirring and the stirring blades directly contact the liquid food, which can easily cause contamination.

[0006] Therefore, a sampling device for food detection is proposed. Utility Model Content
