Description

Technical Field

[0001] The invention relates to the technical field of food detection, in particular to a high-efficiency detection device for heavy metal ions in food. Background Art

[0002] In the process of food processing, it is often necessary to detect the content of heavy metals in food. The detection of heavy metals mainly uses the reaction of heavy metals with color developers. In the existing detection, the food needs to be divided into multiple samples, and multiple types of heavy metals need to be detected in turn. Multiple color developers need to be detected in turn, and the detection efficiency is low. In an application number CN202111110892.7, an efficient detection device for heavy metal ions in food includes a bottom plate, which can crush the food and then contact the color developer more evenly and fully, with higher detection accuracy, and can divide the food to be detected into multiple portions, and simultaneously complete the dropping operation of multiple different color developers, greatly improving the detection efficiency; another application number CN202110611430.7 is an efficient detection device for heavy metal ions in food, including a platform, when the crushing structure is working, the food is crushed into powder or fluid or colloid and filled into the through holes on the rotatable partition plate in turn, and then the color developer is dripped into the crushed food in each through hole in turn by means of an adding mechanism, and the heavy metal content in the food is accurately judged according to the depth of color.

[0003] Both of the above-mentioned two sets of devices separate the solid food, stir and break it up, and then react with the color developing reagent by mixing and dissolving it. However, there are still certain disadvantages in actual detection:

[0004] Since the hardness of solid food varies and the size of the food particles varies, the process of breaking the solid food particles into uniform sizes is inefficient and time-consuming, resulting in low overall detection efficiency.

[0005] Due to the stirring, breaking up and crushing method, when solid food is stirred and broken up at high speed, the solid food particles are easily heated up and become burnt and carbonized, thus affecting the accuracy of the heavy metal detection results.

[0006] Therefore, it is necessary to solve the problems that still exist in the above-mentioned existing devices. Summary of the invention

[0007] In view of the deficiencies in the prior art, the present invention provides a highly efficient detection device for heavy metal ions in food, which solves the problems that, when the prior art detection device for heavy metal ions in food is used, the processing efficiency is low and the effect is poor due to the direct stirring method used to crush and mix the solid food pieces.

[0036] Embodiment 3: A foaming component 3 is arranged on the outside of the rotating drum 2, and the foaming component 3 includes a shell 31. The shell 31 is made of a pressure-resistant, wear-resistant and corrosion-resistant material. The outer surface of the shell 31 is fixedly connected to the outer surface of the feeder 1 and is arranged at an angle. A hopper 32 is penetrated and connected to the inside of the shell 31. The hopper 32 interacts with one side of the conveyor belt of the feeder 1 to receive solid food fragments during transportation.

[0037] The main body of the shell 31 is provided with a through material trough 36, which is convenient for discharging the foamed solid food crumbs, and is externally connected to an existing mixing device for heavy metal detection of solid food. The outer surface of the shell 31 is fixedly connected to a toggle motor 37, and the toggle motor 37 is electrically connected to an external control circuit.

[0038] By setting up the foaming component 3 and utilizing the circular plate 33 to drive the partition plate 35 to rotate, the transported solid food crumbs can be transported in batches and in a quantitative manner. At the same time, during the transportation process, the solid food crumbs can be sprayed with sterile water to foam the crumbs, so as to loosen the structure of the crumbs and improve the efficiency and effect of breaking up and mixing the crumbs. At the same time, since the crumbs are foamed with sterile water, the sterile water can absorb the heat generated by the stirring during the stirring and breaking process, thereby avoiding the problems of scorching and carbonization of the material due to temperature rise, thereby improving the detection effect and the accuracy of the detection results.

[0039] Embodiment 4: A cleaning unit 34 is provided on the outside of the circular plate 33, and the cleaning unit 34 includes a groove 341.

[0040] A solid pipe 344 is rotatably connected inside the groove 341. The solid pipe 344 is made of a material that is pressure-resistant, wear-resistant, corrosion-resistant and has good sealing properties. A filter screen may be provided at one end of the air inlet to filter external impurities. The outer surface of the solid pipe 344 is fixedly connected to the main body of the shell 31.

[0041] By setting up the material cleaning unit 34, when the partition 35 drives the foamed solid food fragments to move to the material trough 36, for some foamed fragments that are attached and not discharged, the fan 345 works through the air hole 346, the air pipe 342 and the solid pipe 344, and can pump external air into the air bag 343 to make the air bag 343 expand, so that the foamed fragments can be squeezed out, thereby improving the efficiency and effect of feeding.

[0042] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0043] During operation, the solid food to be tested is added into the interior of the slide tube 4 through the material pipe 8, and then the rotating motor 14 drives the rotating rod 15 to rotate, so that the rotating plate 9 drives the scraper 10 to rotate continuously inside the drum 2, and at the same time, one end of the rotating rod 15 drives the fixed ring 77 to rotate synchronously, and the fixed ring 77 drives the gear 76 to rotate along through the transmission action of the connecting rod 75 and the pin rod 79, so that the gear 76 and the rack 74 are meshed, so that the rack 74 drives the slide 71 to slide through the telescopic cylinder 73, and when the slide 71 slides, on the one hand, it compresses the spring 72, and on the other hand, it pushes the solid food to slide inside the slide tube 4 through the slide rod 6 and the push plate 5, when the solid food moves and contacts with the scraper 10, the scraper 10 cuts it, and the cut pieces move with it, fall on the feeder 1 through the through slot 12 for transportation, and are crushed by the pressure roller 16 during transportation to further crush them, and then the crushed pieces continue to be transported;

[0044] When the push plate 5 moves to make the scraper 10 contact the arc groove 11, the solid food is completely cut and divided, and then the output end of the telescopic cylinder 73 retracts to drive the rack 74 to move downward, so that the rack 74 and the gear 76 are disengaged, and then the spring 72 rebounds to make the carriage 71 and the rack 74 move in the opposite direction to reset. After the complete reset, the output end of the telescopic cylinder 73 extends to make the rack 74 mesh with the gear 76 again, so as to perform a continuous solid food cutting operation;

[0045] The crushed solid food fragments fall at the feeding end of the feeder 1, and are received and guided by the hopper 32, thereby falling into the interior of the housing 31. At the same time, the two adjacent partitions 35 quantitatively divide the crushed fragments into batches. At the same time, the output end of the toggle motor 37 drives the partition 35 to rotate through the circular plate 33 to toggle the quantitatively divided batches of fragments. In the toggle process, the external sterile water supply device sprays sterile water on the fragments through the water pipe 39 and the spray pipe 38, so that the fragments are foamed during the toggle process. When the foamed fragments move to the material trough 36, they slide downward by tilting, thereby falling into the mixing device for stirring and mixing. At the same time, for some foamed fragments that are attached and not fallen, The fan 345 works and pumps outside air into the interior of the airbag 343 through the fixed tube 344, the air hole 346 and the air pipe 342, so that the airbag 343 expands and squeezes out the attached foamed fragments. Then, after the fan 345 stops working, the air inside the airbag 343 is discharged in the reverse direction, and the airbag 343 rebounds to restore its shape for continuous use, and avoids interfering with the rotation of the partition 35. After all the fragments are discharged, the spray pipe 38 continues to spray sterile water to clean the interior of the shell 31, and the cleaned sterile water carries the remaining materials and is discharged into the mixing device through the material trough 36 for stirring and mixing. Then, the solid food can be tested for heavy metals through existing testing equipment.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
