[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 , an embodiment provided by the utility model:

[0021] A one-stop food inspection pretreatment test bench comprises a fume hood 1, a movable seat 2 and a sampling module 3 are fixedly connected to the inner side of the fume hood 1, a turntable 4 is movably connected to the inner side of the fume hood 1, a centrifuge 5 is arranged on the inner side of the fume hood 1, a first manipulator 6 and a second manipulator 7 are arranged on the inner wall of the fume hood 1, an air blowing component 8, an oscillator 9 and a liquid adding component 10 are arranged on the surface of the fume hood 1, an incubator 21 is slidably connected to the surface of the movable seat 2, and a protective door 22 is movably connected to the surface of the incubator 21.

[0022] Furthermore, the turntable 4 is used for centrifuge tube conversion during sample pretreatment. Samples to be tested are waiting. The turntable 4 can hold 8*6 sets of sample conversion tubes. According to the prompts of the operating software, the specified centrifuge tubes are placed in the corresponding positions or the used centrifuge tubes are replaced.

[0023] Furthermore, the air blowing component 8 is used to concentrate the sample pretreatment extract. The air blowing component 8 can simultaneously meet the needs of twelve samples being air-blown at the same time and twelve samples being waiting. The air blowing temperature and air blowing time of the air blowing component 8 are automatically updated according to the detection items, and the air blowing needle is regularly maintained according to the maintenance requirements.

[0024] Furthermore, the injection module 3 transports the sample to the sample loading position. Samples can be placed, confirmed, and recovered in this area. The samples are placed on the sample rack for transportation. The injection module 3 can hold up to thirty samples. Each sample unit rack needs to hold samples of the same test item. When placing the sample rack, it is necessary to follow the prompts of the operating software.

[0025] Furthermore, the incubator 21 is used for high-temperature incubation of sample pretreatment. The incubator 21 is fully loaded with twelve samples, and the incubation temperature is automatically changed according to the detection items.

[0026] Furthermore, the oscillator 9 can be used in conjunction with grinding beads for sample grinding and pre-treatment extraction oscillation.
