DESCRIZIONE
The invention relates to a method for producing output goods of the highest possible quality from input goods, wherein the input goods to be processed are optically detected, brought to a target weight and then formed into a form suitable for packaging and / or further processing. In the known methods, tuna is canned or otherwise packaged, the structure being substantially lost through processing. This avoids the invention by the method steps using frozen input material for carrying out the method, detecting the position, shape and size of the individual input material via an optical detection means with direct or indirect consideration of the fiber position of the tuna meat, calculating at least one cut line through the input product for truncation a tuna cut having a desired target weight and / or shape, the calculation of the cut line including an optimization process whereby, in addition to determining the volume required to reach the target weight after trimming, the cut line is set as perpendicular as possible to the tuna fibers and cutting along the calculated cutting line in a trimming step.
