Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically a negative pressure sampling device for liquid food. Background Technology

[0002] As society develops and people's lives improve, the variety of food becomes increasingly diverse. Liquid food is a type of food. With people's increasing demands for quality of life, in order to improve the quality of liquid food, it is necessary to sample the liquid food in the storage tanks during the liquid food processing process for testing.

[0003] CN219590025U discloses a negative pressure sampling device for liquid food testing, which relates to the field of sampling device technology. To solve the problem that existing technologies are inconvenient for sampling liquid food at different depths and have poor practicality, a sampling tube is provided inside the telescopic cylinder and extends out of the telescopic cylinder. A second ring plate is fixedly installed on the outer side of the sampling tube along one side of the telescopic cylinder. A sample box is fixedly installed inside the column rod. The sample box is a transparent box, and a transparent plate is fixedly installed on the outer side of the column rod.

[0004] Although the patent solves the problem of not being able to sample liquid food at different depths, the device itself and its interior lack cleaning functions. This means that it cannot be cleaned in time after use, resulting in some residue. When sampling again, this leads to a decrease in sample purity and inaccurate detection accuracy.

[0005] Based on this, a negative pressure sampling device for liquid food is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
