The present invention provides a manufacturing method of pellet type pet feed, which comprises a drying process (A) of respectively sterilizing and drying salmon, walleye pollack head, sweet potato, spinach, carrot and rosemary in a drying chamber (1) having a hot wind blower (2), a dehumidifier (3), an infrared ray lamp (6), an ultraviolet ray lamp (7) and a circulation pipe (4) for circulating hot wind with a blower (5), wherein the sweet potato is sterilized and dried until 5-15% of moisture remains； a pulverizing process (B) of pulverizing the materials dried in the drying process； a mixing process (C) of mixing 20 parts by weight of salmon, 30 parts by weight of walleye pollack head, 35 parts by weight of sweet potato, 5 parts by weight of spinach, 5 parts by weight of carrot and 1 part by weight of rosemary to 100 parts by weight in total, and further mixing vitamin, glucosamine and chondroitin so that the mixture of vitamin, glucosamine and chondroitin becomes 4 parts by weight to 100 parts by weight in total； and a pellet molding process (D) of extrusion-molding the mixed materials so that the mixed materials are coagulated into a pellet form by the adhesion of starch included in sweet potato having moisture. The manufacturing method of pellet type pet feed according to the present invention is characterized in that the dehumidifier (2) and the hot wind blower (1) of the drying chamber (1) are alternately operated, and the infrared ray lamp (6) and the ultraviolet ray lamp (7) are alternately operated every one hour to sterilize the materials input into the drying chamber (1).
