Distributing apparatus comprising: - at least one first manifold comprising a plurality of first ports for the passage of material; - at least one second manifold comprising a plurality of second ports for the passage of material; - at least one transport portion (7; 8) for transporting material, said at least one transport portion comprising at least one first mouth that is movable with the possibility of selectively assuming a plurality of positions in each of which is connected to a respective first port, said at least one transport portion comprising at least one second mouth that is movable with the possibility of selectively assuming a plurality of positions in each of which is connected to a respective second port, to allow passage of material, selectively, between any first port and any second port; - valve means arranged to selectively open or close at least one of said second ports and/or valve means arranged to selectively open or close at least one of said first ports; wherein said first ports are arranged along a first circumference and wherein said second ports are arranged along a second circumference that is parallel to said first circumference, said first mouth being provided with a rotation motion around a rotation axis which passes through the centers of said first and second circumferences and which is orthogonal to said first and second circumferences, said second mouth being provided with a rotation motion around said rotation axis; characterized by comprising sensor means for detecting the presence of material arranged in said transport portion (7; 8) and/or sensor means for detecting the presence of material arranged in at least one or each of said first ports and/or in at least one or each of said second ports. - at least one first manifold comprising a plurality of first ports for the passage of material; - at least one second manifold comprising a plurality of second ports for the passage of material; - at least one transport portion (7; 8) for transporting material, said at least one transport portion comprising at least one first mouth that is movable with the possibility of selectively assuming a plurality of positions in each of which is connected to a respective first port, said at least one transport portion comprising at least one second mouth that is movable with the possibility of selectively assuming a plurality of positions in each of which is connected to a respective second port, to allow passage of material, selectively, between any first port and any second port; - valve means arranged to selectively open or close at least one of said second ports and/or valve means arranged to selectively open or close at least one of said first ports; wherein said first ports are arranged along a first circumference and wherein said second ports are arranged along a second circumference that is parallel to said first circumference, said first mouth being provided with a rotation motion around a rotation axis which passes through the centers of said first and second circumferences and which is orthogonal to said first and second circumferences, said second mouth being provided with a rotation motion around said rotation axis; characterized by comprising sensor means for detecting the presence of material arranged in said transport portion (7; 8) and/or sensor means for detecting the presence of material arranged in at least one or each of said first ports and/or in at least one or each of said second ports.
