This utility model ensures uniform heat distribution to the food and low energy consumption during heating and heat preservation.

[0004] However, the above-mentioned existing technology still has shortcomings in use: due to the different types of food samples, the outer diameter of the test tubes used for different samples is also different, but the above-mentioned existing technology cannot store and fix sample test tubes with different outer diameters, and can only store a single sample test tube, resulting in low storage efficiency.

[0005] Therefore, this utility model provides a constant temperature drying device for food inspection. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a constant temperature drying device for food inspection, including an insulated box 1, with a flip-top on the top of the insulated box 1, and a partition 11 inside the insulated box 1, which divides the insulated box 1 into a lower heating chamber 12 and an upper loading chamber 13. The lower heating chamber 12 is filled with heating liquid, and a plurality of heat-conducting pipes 2 are provided on the partition 11, extending to the lower heating chamber 12. After the heating liquid is heated, it heats the heat-conducting pipes 2. After the sample tube is inserted into the heat-conducting pipes 2, the heat-conducting pipes 2 heat the sample tube.

[0025] In this technical solution, a support 3 is provided at the bottom of the heat-conducting pipe 2. The top of the support 3 is provided with a first support frame 4, a second support frame 5, and a third support frame 6, which are spaced out from the inside to the outside. The first support frame 4, the second support frame 5, and the third support frame 6 correspond to three sample tubes with different outer diameters. The first support frame 4, the second support frame 5, and the third support frame 6 are elastically slidably connected to the support 3. When the sample tube with the smallest outer diameter is inserted into the heat-conducting pipe 2, it will be supported and limited by the first support frame 4. Similarly, the second support frame 5 and the third support frame 6 will support and position the sample tubes with other outer diameters respectively.

[0026] Specifically, the support 3 includes a positioning sleeve 31. The bottom middle parts of the first support frame 4, the second support frame 5, and the third support frame 6 are respectively fixedly connected to a first sleeve 41, a second sleeve 51, and a third sleeve 61. The second sleeve 51 is sleeved outside the first sleeve 41 and outside the third sleeve 61. The third sleeve 61 is sleeved inside the positioning sleeve 31. The two adjacent ones of the positioning sleeve 31, the first sleeve 41, the second sleeve 51, and the third sleeve 61 are all clearance sliding fits.

[0027] The support 3 includes a first support spring 32, a second support spring 33, and a third support spring 34. The first support spring 32, the second support spring 33, and the third support spring 34 are sleeved in the positioning sleeve 31 and their tops abut against the bottoms of the first sleeve 41, the second sleeve 51, and the third sleeve 61, respectively. It should be noted that the first support spring 32, the second support spring 33, and the third support spring 34 have different lengths, and their lengths gradually decrease. In addition, the heights of the first support frame 4, the second support frame 5, and the third support frame 6 are also different. The purpose of this arrangement is to provide space for the movement of the first support frame 4 and the second support frame 5.

[0028] In this embodiment, the first support frame 4, the second support frame 5 and the third support frame 6 are cage-shaped structures and their inner walls are all fixedly fitted with shock-absorbing rubber sleeves 7. The function of the shock-absorbing rubber sleeves 7 is to elastically compress the corresponding sample tubes to avoid damaging the sample tubes.

[0029] In this embodiment, the top of the heat pipe 2 extends above the partition 11. A cap 8 is screwed onto the outside of the heat pipe 2. A sealing plate 811 is rotatably connected to the bottom of the cap 8 via a support shaft 81. The cap 8 serves to seal the heat pipe 2, and together with the lower heating chamber 12, it ensures a constant temperature environment for the heat pipe 2. The sealing plate 811 seals the opening of the sample tube.

[0030] Furthermore, a drying rod 9 is embedded in the bottom of the sealing plate 811. In specific implementation, an insertion hole can be opened at the bottom of the sealing plate 811, and the drying rod 9 is inserted and connected to the insertion hole. The function of the drying rod 9 is to ensure that the sample tube is in a dry state.

[0031] In this embodiment, a heating tube 101 is provided in the lower heating chamber 12. The heating tube 101 generates heat when energized. A water inlet pipe 15 and a water outlet pipe 16 are provided on one side of the heat preservation box 1, which are connected to the lower heating chamber 12. The water inlet pipe 15 is the channel for liquid to enter the lower heating chamber 12. After the heating tube 101 generates heat, it heats the liquid, and then the liquid heats the heat conduction tube 2 evenly.

[0032] Working principle: When using the sample tube with the largest outer diameter, which needs to be dried and stored at a constant temperature, first unscrew the cap 8, then insert the sample tube into the heat-conducting pipe 2. The bottom of the sample tube will be inserted into the third support frame 6. Then, reset the cap 8. Under the pressure of the sealing plate 811, the sample tube will sequentially press against the first support frame 4 and the second support frame 5, and the corresponding first support spring 32, second support spring 33 and third support spring 34 will be compressed. At this time, the sample tube is fixed. Similarly, sample tubes with other outer diameters can be placed. When the sample tube needs to be taken out, unscrew the cap 8. The reset of the first support spring 32, second support spring 33 and third support spring 34 will push the mouth of the sample tube out of the mouth of the heat-conducting pipe 2. At this time, the sample tube can be manually taken out.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
