Throughput rate from reject manufacture is approximately 250kg & 400kg per hour. The unique method of opening each cigarette avoids the use of knives, thus reducing tobacco degradation to a minimum, and eliminating any contamination from shredded filter tips or paper.
Reject material is loaded into a hopper – capacity 34kg – and carried by a slatted elevator belt up to a chute. This feeds a vibrated, aligning conveyor and ensures that the cigarettes are positioned longitudinally along the belt for correct presentation to the wetting band and subsequently to the opening head. While on the wetting band, each cigarette is lightly compressed by a plain roller to ensure that a continuously dampened strip is formed on the paper. Under the greater pressure of the twin rollers in the opening head, each cigarette splits along the dampened, and hence weakened strip.
The waste now contacts a rotary bat flail that completes the opening process and the primary separation of the tobacco. This together with the paper and tips, falls down a chute onto a double section screening conveyor. Here the tobacco passes through the screen into a vibrating chute that feeds the tobacco discharge conveyor. Before passing over the second section, the paper and tips are forced pneumatically into a cyclonic separator to reclaim any small residue of tobacco dust. They are then passed onto the second section of the screening conveyor, this being the completion of the separation process in the COP 4 plant.
However the COP 5 has an additional fan fed cyclonic separator which in turn passes the paper and filters to a rotary sieve. This ensures the maximum reclamation of tobacco.
The COP series of tobacco reclamation plant has a robust, welded frame, requiring only a flat floor for free standing installation. Maintenance is of a simple, routine nature, in the main only requiring semi-skilled staff.
A central control panel is provided for ease of operation of all electrical equipment.
