Food quality safety detection device and detection method thereof

The invention relates to the technical field of food detection and discloses a food quality safety detection device and a detection method thereof. The food quality safety detection device comprises a box shell, wherein a canned sample is movably placed on one side of the bottom of the box shell, a strong oxidant is movably placed on the other side of the bottom of the box shell, and a rotating arm is movably installed above the canned sample and is driven by electricity; the bottom of the rotating arm is movably connected with a turntable, the bottom of the turntable is fixedly connected with a threaded rod, and the bottom of the threaded rod is movably provided with a pressure button. The rotating arm is driven to rotate to drive the rotating disc, so the threaded rod rotates, descends and penetrates into a canned sample, the pressure button is pressed by the bottom of the can, so the elastic piece jacks up the reversing column to open the side opening, the circuit bottom negative connector, the iron block negative connector and the rotating arm negative connector are connected, and the rotating arm drives the rotating disc to rotate and ascend reversely; an iron block generates repulsive force, so the N-pole magnet ascends to extract a sample, and a problem that a powdery sample is difficult to extract a bottom sample during detection is solved.
