Flattening of conditioned raw stems before cutting is an established practice in the CRES processing in order to increase the filling power and to optimize the cutting process. For this process HEINEN KÖHL offers the Stem Flattener.
Two hard chill-cast rollers are mounted on self-aligning roller bearings and direct driven by two shaft-mounted geared brake motors. Cup springs obtain the roller position and protect the rollers against damage. Cleaning of the rollers is done by 2 easy replaceable scrapers. Steam and water application to the roller will avoid the build-up of tobacco. An optical blockage detection is monitoring the process. The hood made from stainless steel is equipped with large service lids with safety sensors.
Optionally the Stem Flatteners can be equipped with a grinding unit for smoothing the rollers incl. switch cabinet for automatic grinding procedure.
