Process and a machine for producing a filled sheet of process cheese, as well as a filled sheet of process cheese
A process of producing a filled sheet of process cheese, in which process cheese and a filling are co-extruded into a packaging material to produce a strand having a thickness, the strand is separated at predetermined locations to produce separate sheets, in which the filling is fully enclosed. A machine for producing filled sheets of process cheese, having a co-extrusion nozzle with an outer port for extruding an outer component and an inner port for extruding an inner component fully enclosed by the outer component into packaging material to form a co-extruded strand. The machine may comprise a device for reducing the thickness of the co-extruded strand, such as two or more cooperating rollers, and a device for separating the co-extruded strand, such as two or more rollers having ridges. A sheet of process cheese filled with a filling fully enclosed by the process cheese and having a thickness of 6 mm or less is also disclosed.
1. A process of producing a filled sheet of process cheese, the process comprising:
co-extruding the process cheese and a filling into a packaging material to produce a continuous, filled strand having a thickness; and
separating the continuous, filled strand at predetermined locations to produce separate sheets, in which the filling is fully enclosed on all sides by the process cheese,
wherein the step of co-extruding the process cheese and a filling further comprises co-extruding the filling in an inner tube having an inner port for extruding the filling and an outer port for extruding the process cheese, and wherein a cross-section area of the inner port is about one sixth of a cross sectional area at a beginning of the inner tube, and wherein a cross-section area of the outer port is about one third of a cross-sectional area at a beginning of the outer tube.
