Description

Technical Field

[0002] Food canning is a preservation method that seals food in a container, kills most microorganisms through a sterilization process, and maintains airtight and vacuum conditions to store food at room temperature for a long time. The airtightness of canned food determines the quality and pass rate of canned food, so it is necessary to sample and test the airtightness of canned food leaving the factory.

[0003] After searching, the utility model patent announcement number is CN 218496351 U, which proposes an airtightness detection device for food cans, including a water tank and a support plate. The support plate is placed horizontally inside the water tank, and a plurality of floats are evenly fixed on the surface of the support plate. Slide rods that guide the support plate to move up and down are fixed vertically between the four corners and the bottom of the water tank through the horizontal plate. The four slide rods are parallel to each other and can slide through the four corners of the surface of the horizontal plate. A vertical rod is vertically welded and fixed on the top of the horizontal plate. After the can or pop-top can is placed on the surface of the support plate inside the frame, the pressure net can be pressed down to make the overall gravity greater than the buoyancy, so that the support plate drives the can or pop-top can to slowly immerse in the water as a whole, which is not easy to cause bubbles or splashes. The seal at the top can be quickly and accurately observed to see if there are bubbles discharged due to water ingress, and then determine whether there is a leak.

[0004] In the existing food can air tightness detection device, food cans are placed together for air tightness detection. When adjacent food cans are not airtight, bubbles are generated, causing the bubbles to mix together, making it inconvenient for users to observe. Utility Model Content
