The invention discloses a rotating disc type food slice processing machine. The rotating disc type food slice processing machine comprises a rotating disc, fastening nuts, a feed mechanism, a slurry hopper, a driving machine box, a rotary driving shaft, mold plates and a mold opening cam, wherein the fastening nuts are arranged on the outer side of the rotating disc; the feed mechanism is arrangedon the lower side of the rotating disc; the slurry hopper is arranged at the left end of the feed mechanism; the mold opening cam is mounted in the feed mechanism; the driving machine box is mountedat the left end of the mold opening cam; the rotary driving shaft is mounted in the rotating disc; the mold plates are mounted on the inner side of the rotating disc; and the mold opening cam is arranged between the rotating disc and the feed mechanism. The rotating disc type food slice processing machine has the advantages of being firm in whole structure, stable in operation, high in degree of automation, and convenient to control and use. Through the coordination work of the mold plates and the mold opening cam, a food is made into slices, and the nine mold plates are evenly mounted in therotating disc in a spaced manner, so that a large quantity of foods can be made at the same time, and the rotating disc type food slice processing machine is practical.
