Description

Technical Field

[0001] The utility model belongs to the technical field of bean product preservation, and in particular relates to a preservation device for bean product safety detection. Background Art

[0002] As an important source of protein, the safety and quality testing of test samples is crucial to protecting public health. After preparation, test samples are rigorously tested for content of heavy metals, food additives, aflatoxins, nitrites, and other substances.

[0003] However, before testing, bean products from multiple areas need to be sampled and transferred in batches. If the test samples are exposed to the external environment for a long time, such as temperature and humidity problems or the invasion of pollutants, the test samples are likely to deteriorate, resulting in large deviations in the test indicators, affecting the detection accuracy of the test sample indicators. At the same time, during the process of moving the fresh-keeping device, since ordinary storage plates lack effective limiting structures, the test samples are prone to shaking and collisions, causing damage to the shape and structure of the test samples, thereby affecting their detection effect. Therefore, it is necessary to provide a fresh-keeping device for soy product safety testing to ensure the freshness and safety of the samples. Utility Model Content

[0004] In order to overcome the problem in the prior art that, during the process of batch sampling and transfer of soy products, if the test samples are exposed to the external environment for a long time, such as unsuitable temperature and humidity or the invasion of pollutants, the test samples are easily deteriorated, resulting in a large deviation in the test indicators and affecting the detection accuracy of the test sample indicators. At the same time, during the movement of the fresh-keeping device, due to the lack of an effective limiting structure on the ordinary storage plate, the test samples are easily shaken and collided, causing damage to the shape and structure of the test samples, thereby affecting its detection effect. The utility model provides a fresh-keeping device for soy product safety testing. By cooperating with a semiconductor cooling plate and a fan, the low temperature environment in the fresh-keeping box can be effectively maintained, the deterioration rate of the test samples can be slowed down, thereby ensuring the freshness of the samples and providing an accurate data basis for testing. The provision of a limiting groove effectively limits the movement space of the test samples, reduces the damage to the samples caused by shaking during the transfer process of the device, thereby ensuring the integrity of the test samples and the accuracy of the test results. The operator manually pushes the push rod at the bottom end of the storage plate to make the test samples disengage from the limiting groove, facilitating shoveling or taking them, and effectively protecting the shape and structural integrity of the test samples.

[0005] To achieve the above-mentioned purpose, the present invention is realized through the following technical solutions: a fresh-keeping device for bean product safety detection mainly includes a fresh-keeping box, a box cover, a fan, a semiconductor cooling sheet, a support block, a storage slot, a temperature sensor, a controller, and a storage plate.

The ends of the storage grooves 6 are snap-fitted into the positioning grooves 501 and arranged in an array along the support block 5, with gaps provided between adjacent storage grooves 6. A plurality of partitions 601 are equidistantly provided in the storage grooves 6, and the storage grooves 6 are divided into a plurality of limiting grooves 602 by the partitions 601. A top rod 901 is threadedly connected to the bottom end of the storage plate 9, and the top rod 901 is slidably connected to the through hole at the bottom of the limiting groove 602.

[0019] During use, the operator opens the lid 2 of the fresh-keeping box 1 and places the sampled test sample on the storage plate 9 in the storage slot 6. After placement is completed, the lid 2 is closed and locked to avoid. Then, the operator sets the temperature required for fresh-keeping through the controller 8. The controller 8 will adjust the working state of the semiconductor refrigeration chip 4 according to the set temperature value. Through the heat absorption and refrigeration principle of the semiconductor refrigeration chip 4, the interior of the fresh-keeping box 1 is always kept at a low temperature, thereby achieving a low-temperature preservation effect for the test sample stored in the fresh-keeping box 1, slowing down the deterioration rate of the test sample, thereby ensuring the freshness of the sample and providing an accurate data basis for the test; the temperature inside the fresh-keeping box 1 is monitored in real time by the temperature sensor 7, and the data is fed back to the controller 8. The controller 8 automatically adjusts the working state of the fan 3 and the semiconductor refrigeration chip 4 according to the data of the temperature sensor 7 to maintain the temperature inside the fresh-keeping box 1; at the same time, the fan 3 is started to dissipate heat to the semiconductor refrigeration chip 4 through the ventilation holes 1011 on the side wall of the shell 101 to maintain the stable operation of the semiconductor refrigeration chip 4.

[0021] An annular groove is provided on the top of the fresh-keeping box 1, in which an annular sealing ring 13 is embedded.

[0023] A handle 14 is installed on the top of the box cover 2 to facilitate operators to move the device.

[0024] Working process:

[0025] During use, the operator opens the lid 2 of the fresh-keeping box 1 and places the sampled soy products on the storage plate 9 in the storage slot 6. After placement is completed, the lid 2 is closed and locked to avoid. Then, the operator sets the temperature required for fresh-keeping through the controller 8. The controller 8 will adjust the working state of the semiconductor refrigeration chip 4 according to the set temperature value. Through the heat absorption and refrigeration principle of the semiconductor refrigeration chip 4, the interior of the fresh-keeping box 1 is always kept at a low temperature, thereby achieving a low-temperature preservation effect for the test samples stored in the fresh-keeping box 1, slowing down the deterioration rate of the test samples, thereby ensuring the freshness of the samples and providing an accurate data basis for the test; the temperature inside the fresh-keeping box 1 is monitored in real time by the temperature sensor 7, and the data is fed back to the controller 8. The controller 8 automatically adjusts the working state of the fan 3 and the semiconductor refrigeration chip 4 according to the data of the temperature sensor 7 to maintain the temperature inside the fresh-keeping box 1; at the same time, the fan 3 is started to dissipate heat to the semiconductor refrigeration chip 4 through the ventilation holes 1011 on the side wall of the shell 101 to maintain the stable operation of the semiconductor refrigeration chip 4.

[0026] When it is necessary to take the test sample for testing, the operator opens the lid 2 of the fresh-keeping box 1 and manually lifts the top rod 901 at the bottom end of the storage plate 9. Under the guidance of the guide rod 902, the storage plate 9 moves upward, so that the test sample is separated from the limiting groove 602, which is convenient for shoveling or taking it, effectively protecting the shape and structural integrity of the test sample; the setting of the limiting groove 602 effectively limits the moving space of the test sample, reduces the sample damage caused by shaking during the transfer process, thereby ensuring the integrity of the test sample and the accuracy of the test results.
