The invention provides an intelligent food safety detecting device. The intelligent food safety detecting device comprises a placing box, anti-slip blocks, a placing seat, a clamping plate, a supporting rod, a mounting sleeve, a mounting plate, a motor, an eccentric wheel, a PLC, a mashing cylinder structure, a rinsing tank structure, a distillation tank structure, a disposal container structure and a protection cover structure, wherein the anti-slip blocks are respectively inlaid in the left side and the right side of the lower surface of the placing box; the placing seat is glued-jointed tothe upper middle part of the inner wall of the placing box, and the clamping plate is glued-jointed to the lower part of the inner wall of the placing box; and the upper end of the supporting rod is welded to the lower surface of the mounting plate, and the lower end is welded to the upper surface of the mounting sleeve. The intelligent food safety detecting device has the beneficial effects thatthe mashing cylinder structure is arranged, so that convenient and classified placing of different foods is facilitated; and besides, different foods can also be mashed, so that the problem that the residual foods influence the detection data when reusing is needed, can be solved.
