[0002] Sample pretreatment can remove impurities in samples, enrich target detection objects, and improve the sensitivity of detection instruments, thereby shortening detection time and improving detection efficiency. However, existing sample processing devices need to be cleaned each time they are used. The sample processing time before food testing is relatively long, which has certain defects.

[0003] The defects of the existing food testing sample processing device are:

[0004] 1. In the patent document CN216349860U, the main consideration is how to improve the positioning effect of the reagent tube, but it does not take into account that the existing sample processing device needs to be cleaned every time it is used, and the sample processing time before food testing is long;

[0005] 2. In the patent document CN213985895U, the uniformity of mixing the sample and the reagent is improved mainly by simplifying the operation process, but the problem of poor flexibility of the existing sample processing device during use is not taken into account;

[0006] 3. In the patent document CN218381950U, the continuous bursting of bubbles is mainly used to drive the tumbling of the reagent to improve the uniformity of the mixing of the sample and the reagent. It does not take into account that the existing sample processing device is not equipped with a self-monitoring structure when in use, and cannot monitor the temperature of the sample when drying the sample, which may easily lead to the situation that the sample temperature is different from the temperature set by the electric heating plate due to a malfunction;

It does not take into account that the existing sample processing device can only adjust the drying temperature in a single way when drying the sample. When testing multiple groups of samples, it cannot be adjusted according to the different drying temperatures of the samples, and has poor flexibility. Summary of the invention

When detection is required, the reconstitution solution is added to the dried centrifuge tube to obtain the test solution.

[0059] Further, the method of using the sample processing device is as follows:

[0060] S1. When in use, open the sample processing integrated machine 1 and select a split sleeve 9 or an integrated sleeve 9 according to the sample to be tested;

After crushing, filter the sample in the sleeve 9 and weigh the sample of appropriate weight and put it into the centrifuge tube. Add solvent to the centrifuge tube according to the detection needs, and oscillate it through the oscillator 2 when oscillation and mixing are required. After the extraction is finished, the extractant is dripped into the centrifuge tube, and the tube is continuously shaken. After the shaking is finished, the tube is placed in a centrifuge 3 for centrifugation. At this time, the bottom of the centrifuge tube is a tissue sample homogenate, which is divided into three layers from bottom to top. The middle layer clear liquid is taken and placed in the centrifuge tube, and after the oxidant is dripped, the tube is placed in a dryer 6 for air drying. Then, the reconstitution solution is dripped into the dried centrifuge tube, and the solid residual liquid on the bottom wall and the inner wall of the centrifuge tube is fully re-dissolved, and a part of it is taken as the test liquid. Then, the test liquid can be subjected to food testing operations such as heavy metal detection, pesticide residue detection, and illegal additive detection as needed.
