Abstract
Description
Technical Field
[0001] This utility model relates to the field of test tube processing technology, and in particular to a test tube drying device for food testing. Background Technology
[0002] Food testing involves detecting whether food contains harmful substances such as heavy metals and aflatoxin to ensure food safety. Test tubes are frequently used in food testing. After use, test tubes need to be cleaned and disinfected, and then dried using a drying device. Because test tubes are long, the bottom inside is difficult to dry, making the drying effect of existing test tube drying devices less than ideal, resulting in low drying efficiency. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies where test tubes are too long, making it difficult to dry the bottom inside the test tubes, resulting in less than ideal drying effects and low drying efficiency. Therefore, this invention proposes a test tube drying device for food testing.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] Design a test tube drying device for food testing, including a base, a connecting plate installed on the top of the base, a plurality of hot air jet pipes arranged in the middle of the top of the connecting plate, telescopic components arranged on both sides of the top of the connecting plate, a fixed plate arranged on the top of each of the two telescopic components, a plurality of pneumatic telescopic rods installed on each of the two fixed plates, clamping blocks installed on the extension rods of the plurality of pneumatic telescopic rods, and the plurality of clamping blocks being arranged in pairs corresponding to the plurality of hot air jet pipes.
[0006] Preferably, all of the clamping blocks are configured as arc-shaped.
[0007] Preferably, a buffer block is provided on the outer side of each of the clamping blocks.
[0008] Preferably, each of the buffer blocks has a plurality of slots.
[0009] Preferably, the buffer block is evenly arranged among several slots.
[0010] Preferably, the outer sides of several of the hot gas ejection pipes are all inclined.
[0011] The present invention provides a test tube drying device for food testing, which has the following advantages: The device inserts one end of a hot air jet pipe into the interior of the test tube, thereby activating the heating components and fan within the cavity. This accelerates the drying process inside the test tube, reducing the drying time. Furthermore, the buffer block clamps the test tube, reducing the contact area between the clamped area and the buffer block. This also reduces the pressure exerted by the buffer block on the test tube during thermal expansion, further decreasing the likelihood of breakage during drying and improving the drying efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] Example 1: Refer to Figure 1-4 A test tube drying device for food testing includes a base 1, a connecting plate 2 installed on the top of the base 1, a plurality of hot air jet pipes 3 arranged in the middle of the top of the connecting plate 2, telescopic components 4 arranged on both sides of the top of the connecting plate 2, a fixed plate 5 arranged on the top of the two telescopic components 4, a plurality of pneumatic telescopic rods 6 installed on the two fixed plates 5, a clamping block 7 installed on the extension rod of the plurality of pneumatic telescopic rods 6, the plurality of clamping blocks 7 are arranged in pairs corresponding to the plurality of hot air jet pipes 3, the plurality of clamping blocks 7 are all arc-shaped, a buffer block 8 is arranged on the outer side of the plurality of clamping blocks 7, and a plurality of slots 9 are opened on the plurality of buffer blocks 8.
[0019] Combined with appendix Figure 2 It can be seen that a cavity 10 is opened in the base 1, and a heating component 11 is installed in the cavity 10. Several air inlets 13 are provided on one side of the base 1. The several air inlets 13, the cavity 10, and the several hot air exhaust pipes 3 are all in a connected state. A fan 12 is installed in the cavity 10 at the bottom of the several hot air exhaust pipes 3, so that the hot air flow provided by the several hot air exhaust pipes 3 can be faster.
[0020] After placing the test tube to be dried above the corresponding hot air jet pipe 3, activate the corresponding pneumatic telescopic rod 6. The corresponding clamping block 7 will clamp the test tube. Then activate the telescopic assembly 4, so that the fixing plate 5, pneumatic telescopic rod 6, clamping block 7 and test tube move toward the hot air jet pipe 3, so that one end of the hot air jet pipe 3 is inserted into the interior of the test tube. This allows the heating assembly 11 and fan 12 in the cavity 10 to work, and during the internal heating and drying process of the test tube, the drying speed inside the test tube is accelerated, thereby reducing the drying time required for the test tube.
[0021] Example 2: An optimization based on Example 1, with reference to... Figure 1-4 The buffer block 8 is evenly arranged among several slots 9, and the outer sides of several hot gas ejection pipes 3 are all set to be inclined.
[0022] After the slots 9 on the buffer block 8 are evenly arranged, the test tube is clamped by the pairs of buffer blocks 8. At the same time, the area of the contact between the clamped position of the test tube and the buffer block 8 is reduced, and the compression of the test tube by the buffer block 8 during the thermal expansion process is reduced, thereby further reducing the probability of the test tube breaking during the drying process.
[0023] By setting the outer side of several hot gas ejector pipes 3 to be inclined, the appearance of several hot gas ejector pipes 3 is conical, thereby reducing the probability that the bottom of the test tube will be blocked by the outer side of the hot gas ejector pipes 3 when the test tube is clamped in Example 1 and the hot gas ejector pipes 3 heat the inside of the test tube.
[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
