PROBLEM TO BE SOLVED: To provide a circulating conveyer for food capable of efficiently adjusting an internal temperature of a tunnel part covering the space above a circulation-type conveying route through which the food is circulation-conveyed. SOLUTION: The circulating conveyer for the food comprises forming the tunnel part 5 for covering the space above the circulation-type conveying route along in a longitudinal direction of the conveying route for conveying and feeding the food, disposing a cold pipe 24 along in a longitudinal direction inside the tunnel part 5 and enabling the internal temperature of the tunnel part 5 to be adjusted. Inside the tunnel part 5, an upper ventilation opening 32 disposed above the cold pipe 24 and a lower ventilation opening 33 disposed below the cold pipe 24 are provided in a longitudinal direction of the conveying route. The upper opening 32 communicates with the lower opening 33 via communicating pipes 30a, 30b and 30c so that the air can flow through. A blowing means 34 is provided for sucking the air inside the tunnel part 5 into the inside of the communicating pipes 30a, 30b and 30c from either one of the openings 32 and 33 and blowing the sucked air into the other of the openings 32 and 33 to circulate it.
