In particular, the conveyor 3 has a flip paddle 33 that toggles the fry 12 toward the discharge end 15, whereby the flip paddle 33 flips the movable fry 12 toward the discharge end 15. The tumbling device 4 is arranged in the oil tank 11 and is positioned below the conveying device 3, so that the conveying device 3 moves, the tumbling poking row 33 is in tumbling movement, the immersed fried products 12 after molding move under the poking of the tumbling poking row 33, when the fried products 12 move to the tumbling device 4, the fried products 12 can be turned at least once through the coordination of the tumbling poking row 33 and the tumbling device 4, the fried products 12 can be fried by being contacted with oil in multiple surfaces, and the turnover frying of the fried products 12 is realized.
According to the food frying machine 100 of the embodiment of the invention, by arranging the turnover conveying device, the fried products 12 are immersed and molded by the molding device 2, and then are turned over, fried and conveyed to the discharge end 15 at least once by the turnover conveying device, so that the fried products 12 can be turned over, fried more uniformly and crisp, the taste of the fried products 12 is improved, the oil consumption is reduced, and the full automation of the food frying machine 100 is realized.
