Description

Technical Field

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

[0002] Food inspection refers to a discipline that studies and evaluates food quality and its changes. It is based on some basic theories and various technologies of physics, chemistry, and biochemistry, and in accordance with established technical standards, such as international and national food hygiene / safety standards, to inspect the quality of food raw materials, auxiliary materials, semi-finished products, finished products, and by-products to ensure product quality.

[0003] The constant temperature water bath is used for constant temperature heating of water bath and other temperature tests. It is an essential tool for education and scientific research in food hygiene, biology, aquatic products and medical analysis rooms.

[0004] Chinese patent publication number CN215843078U discloses a constant temperature water bath for food inspection, which can position the test tube in a vertical state as much as possible to avoid the test tube leaning against the innermost cover ring and causing liquid spillage. In this way, a test tube can hold as much food as possible to be tested, thereby improving practicality.

[0005] However, compared with the prior art and comparative documents, the existing constant temperature water bath heats and maintains a constant temperature by placing a beaker containing a food sample in the water bath for constant temperature treatment of food. However, in order to meet the placement requirements of beakers of different diameters, the placement hole opened on the top cover of the water bath is relatively large. When the water is heated to a full boil, due to the small number of test samples in the food test, the beaker and the sample are relatively light in weight, and are placed in the water under the effect of buoyancy, which easily causes a large amount of vibration in the beaker, resulting in poor stability, which easily causes the food test sample to shake, affecting the accuracy of the test results. Utility Model Content

[0006] The main purpose of the utility model is to provide a constant temperature device for food inspection and testing.

[0007] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0008] A constant temperature device for food inspection and testing comprises a water bath pot, a top cover is installed on the top of the water bath pot, a water adding hole is opened in the middle of the top cover, placement holes are evenly opened on the top cover, and there are four placement holes, and a limiting component is correspondingly arranged below the placement holes, the limiting component comprises a fixed frame installed at the bottom of the top cover, a floating plate is connected to the bottom of the fixed frame, and the floating plate is a circular ring structure, the inner diameter of the floating plate is equal to the inner diameter of the placement hole, a base is symmetrically installed on the top of the fixed frame, one side of the base is an inclined structure, and a sliding seat is connected to one side of the inclined end of the base, and an empty groove for guiding is provided at the connection between the base and the sliding seat, and connecting seats are symmetrically installed on the opposite side of the sliding seat and the floating plate, and a connecting rod is rotatably connected between the connecting seats.

[0009] Preferably, slide grooves are symmetrically provided on both sides of the fixed frame, and the floating plate is slidably connected to the fixed frame through the slide grooves.

[0010] Preferably, water inlet holes are correspondingly opened below the two side walls of the fixing frame, and the fixing frame has an upper and lower opening structure.

[0011] Preferably, a carrying plate is arranged in the middle of the water bath, and the water bath has a convex block below the carrying plate, and cavities are evenly opened on the carrying plate.

[0012] Preferably, a heating tube is arranged below the supporting plate, the heating tube is in a U-shaped structure, and a bottom plate is arranged below the heating tube.

[0013] Preferably, a temperature sensing probe is installed on one side of the bottom plate, and a pipe for connecting a pump is installed on the bottom plate.

[0014] Preferably, a drain pipe is installed at one end of the pump, and the drain pipe runs through a side wall of the water bath.

[0015] The beneficial technical effects are:

[0016] By setting the limit assembly, the staff places the beaker containing the sample in the fixed frame and adds a certain amount of distilled water into the water bath. At this time, the float plate moves upward along the fixed frame due to the buoyancy of the water. During the movement, the sliding seat is driven by the connecting rod and the connecting seat to move along the base. The opposite surface of the base is an inclined structure, which can make the two sliding seats gather toward the middle of the placement hole until they contact and clamp the outside of the beaker, thereby ensuring the stability of the beaker during the heating and constant temperature process, avoiding shaking of the food testing samples, and thus ensuring the accuracy of the test results.

The sliding seat 404 moves along the base 403 to clamp the beaker, and the base 403 and the sliding seat 404 are connected at a position where the sliding seat 404 is connected. There is an empty groove 6 for guiding, which facilitates the sliding seat 404 to move along the base 403 through the empty groove 6.
