No. 2090923 (2004): Mechanical sheller

Portable mechanical tool composed of 3 toothed cylinders, which when rotating by means of steel sprockets and chains, subject the coffee fruit to bending and torsion efforts, the sprockets form an equilateral triangle equidistant from the center of the main body allowing the existence of an appropriate area to allow the passage of the branch through them and create a shelling effect on the coffee bunches.
