Title: Sepn of impurities from air or a gas - in tobacco treatment, e.g. tobacco dust, fragments, textile components etc
Inventor: LECKBAND UWE
IPC: B01D46/26
Filed: 1974-03-21
Abstract: In a process for separating impurities from the air or other gas used in treatment of tobacco, part of the air is returned to a closed circuit whilst a second part is extracted on the stream leaves the treatment zone. The air stream is introduced approximately tangentially to the ourter surface of a sieve drum (filter drum). A part of the impurities is concentrated by the centrifugal force in a part of the air stream which then by-passes the sieve drum and leaves the closed circuit. The remainder of the air passes through the sieve drum depositing impurities on its outer surface before it is returned to the closed circuit. The separator is advantage simple and inexpensive in relation to its high sepn. efficiency and the large vols. of gas handled.
