Abstract
A tearing mill for comminuting fruits is equipped with a rotatably supported plate having tearing elements And with a stuffing device with a feed screw for delivering the fruits to the plate. A gap of adjustable width exists between the stuffing device and the plate. By means of an independent control of the gap and the rotational speed of the feed screw and plate, a mash structure of the comminuted fruits is achieved which is well adapted to the type of fruits and to subsequent processing of the mash.
Claims22
An apparatus for comminuting organic substance comprising:
- a plate supported rotatably about its axis;
- a motor operatively connected to the plate to rotate the plate about its axis;
- a stuffing device for delivering organic substance toward a face of the plate;
- tearing elements disposed on said face of the plate for separating pieces from the organic substance delivered by the stuffing device during rotation of the plate, the tearing elements extending towards an outer periphery of the plate;
- and
- a plurality of grooves provided on said face of the plate, each groove being positioned along one side of one of the tearing elements and extending towards the outer periphery of the plate to receive the pieces separated from the organic substance and carry the pieces away towards the outer periphery of the plate during rotation of the plate.
