Forming of flour chips can be made in two ways: by direct forming out of dough or cutting out of dough ribbon.
For the first method rotor forming machines with replaceable drums are used; drums define the shape and size of product.
For the second method a pre-forming of dough ribbon is required; it is made by roller extruder, after that the width of ribbon is calibrated by the knife device, the surface of the dough ribbon is dried in a tunnel oven to preserve the shape of the pieces and prevent sticking of pieces after cutting.
Dough pieces of the required size are made on the cutting machine, at this size of chips is defined by replaceable cutting drums of the machine.
