This method has inherent drawbacks such as cumbersome procedures, long processing times, high costs, and limited space. In contrast, aquatic product drug residue testing kits have become a solution for rapid, multi-scenario testing needs due to their ability to be used by grassroots regulatory and testing personnel for rapid pretreatment of aquatic product drug residues at aquaculture ponds.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "fixing", and "connection" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0083] Please see Figure 1-4 The diagram shows the structure of the aquatic product drug residue testing box provided in an embodiment of this utility model. Figure 1 and 2 It is understood that the aforementioned aquatic product drug residue testing kit includes:

[0088] The rotary switch 17 is installed on the panel 2. There are three rotary switches, which are respectively a primary air drying and filtration system, a secondary air drying and filtration system, and a tertiary air drying and filtration system. In the case of different drug residue test samples, different filtration systems can be used to provide qualified air, which increases the detection accuracy and reliability of the test box.

[0089] The air passage 42 is used to transmit the filtered air to the blowpipe box 55, and one end of the air passage 42 is connected to the filtered gas output end of the filter body 42.

[0090] The electromagnetic air pump 43 is used to absorb, compress and discharge air, and the electromagnetic air pump 43 is connected to the filter gas input end of the filter body 41.

[0092] The filter sleeve 19 connects the filter body 41 to the rotary switch 17.

[0093] After the air drying filter is activated by the rotary switch, the electromagnetic air pump 43 drives the internal armature to obtain the air to be filtered through the one-way valve. The air to be filtered is first input into the filter body 41 through the air pipe 42, and the filtered air is then transmitted to the blowpipe box 55 through the air pipe 42 to complete the filtration process.

[0101] The metal protective cover 20 is snapped onto the panel 2, and the thermostat body 51 of the concentrator is fixed to the lower surface of the panel 2.

[0102] After the filtration process is completed, the push rod motor 52 controls the air blowing needle to descend to a preset height, and the filtered air enters the constant temperature body 51 of the concentrator through the air blowing needle 53 for processing, thus completing the concentration process.

[0103] This utility model, through its multi-functional integrated design, integrates homogenization, oscillation, centrifugation, and concentration functions. Multiple modules operate in a coordinated and continuous manner, reducing manual intervention and forming a highly efficient "sample in - test liquid out" process, minimizing sample transfer errors. It employs an 8-channel air-blowing constant-temperature concentrator and a three-stage air drying filter. The pre-drying filter reduces the degree of contamination during concentration. Electric lifting control during the concentration process prevents solution boiling. A full-touch digital display precisely controls temperature, speed, and air volume, improving concentration accuracy. It can monitor the operation of each component in real time, rationally allocate output, and process multiple sample detection data lines, greatly improving the operating efficiency of the testing chamber and reducing the possibility of excessive load.
