Abstract
The present invention is directed to provide an apparatus and method for forming food into doughnut shape that is capable of forming food into rings with a simple structure. The apparatus includes a supplying unit supplying a food material 2; a discharging unit 3 continuously discharging the supplied food material through a nozzle; a forming unit 4 dividing the food material into rings; a conveyor belt 5 carrying the resulting doughnut-shaped food products; and a support unit 6 supporting the products. The supplying unit 2 supplies an outer food material F and an inner food material G to the discharging unit 3 under pressure. The discharging unit 3 includes an inside forming member 32, around which the inner food material G is intermittently discharged from an annular outlet 34, and the outer food material is continuously discharged to sandwich the inner food material G, resulting in formation of a tubular food material. The forming unit 4 includes a plurality of shutter members 40 disposed around the discharging unit 3, and moves the shutter members 40 to divide the continuously discharged tubular food material into pieces of a doughnut shape.
