Pesticide residue detector and detection method thereof

The invention discloses a pesticide residue detector and a detection method thereof, and relates to the technical field of detection equipment.The pesticide residue detector specifically comprises an instrument box and further comprises an equipment box and a rotating shaft arranged at the inner top end of the instrument box, and the inner bottom of the equipment box is provided with a rotating shaft penetrating through the equipment box and rotationally connected with the equipment box; a plurality of blades are evenly arranged outside the rotating shaft in the circumferential direction of the rotating shaft. According to the fruit and vegetable rotary cutting device, fruits or vegetables can be subjected to rotary cutting through a double-shaft motor, meanwhile, a rotating shaft and a stirring rod can be rotated, so that liquid in a stirring box can be effectively stirred, and meanwhile, when a sampling box and the stirring box are cleaned and subsequently dried, the stirring efficiency is improved.
