<p>The invention concerns a device for determining the percentage of the edible portion of a long and narrow fibrous food, utilising a blade (3) pressing with its cutting side on the fibrous food fixed on a support surface (9) from above with respect to said support surface, characterised in that:
- said support surface (9) is fixed on a slide (1) that is longitudinally slidable along a predetermined direction of the plane including the same support surface (9);
- there are comprised driving means of said slide (1);
- there are comprised driving means of said blade (3), that are suitable to move away from said fibrous food, or to bring it nearer to said fibrous food till the blade exerts, on the fibrous part, a force such to compress it without cutting it;
said driving means of said slide (1) and said driving means of said blade (3) being suitable to act simultaneously so that the blade (3) slides on said fibrous food till it arrives to the edible part and separates it by pulling it from the rest of the fibrous food. The invention further concerns the relevant method for determining the percentage of the edible portion of a long and narrow fibrous food.</p> |
