A process and apparatus for making a half-product used in forming puffed food products, the apparatus having two rollers, at least on of them being a cutter roller having cutting teeth, rotating against each other. Product flows between the two rollers in the form of dough strips and an air nozzle is disposed between them to provide air causing deformation of the product and forming an air pocket. The teeth may be both rollers and in meshing contact with one another. The teeth also have a V-shape with a rounded radius at the cutting end so that it rolls into the dough product and back out thereof to form a large sealing surface between the two pieces of dough and forming an improved seal so that when the food product is fried the sealed area does not split open from increased pressure inside the hollow food product. |
