The utility model relates to a copper-based nutritional protective agent production device, which comprises a control box, automatic feed hoppers, weight sensors, a slurry-type mixed reaction kettle, a heating device, a cooling water device, a mixer, a vertical sand mill, a valve, a centrifugal device, a spray drying tower, a pressure spray agitation conveyer, a drying device, a jet mill, a quantitative packaging machine and the like, wherein the control box is centered on a strain signal input five-digit meter and a single-chip microcomputer; the weight sensors are installed below the automatic feed hoppers, the weight sensors are connected with the strain signal input five-digit meter through a 485 bus, and the automatic feed hoppers are directly connected with the mixer; a discharge outlet at the lower end of the slurry-type mixed reaction kettle is connected with a feed inlet of the mixer, and the mixer is also connected with the single-chip microcomputer; the mixer is provided with a waste liquid discharge outlet; and the drying device is connected with the jet mill. The copper-based nutritional protective agent production device and equipment are simple and novel; and due to the pressure spray agitation conveyer, the problem that the materials cannot be conveyed to the drying tower through a diaphragm pump because the materials are full of foams is solved.
