Sorting

Description

Sorting – This stage of the process is aided by modern technology. Optical systems search for the needle in the haystack, and remove small parts like feathers, bits of plastic, pieces of wood, paper or aluminium foil. Pneumatic sorters, which combine innovative camera technology with an air separator, are used for example – nothing escapes their detection. Non-tobacco related materials are reliably identified and removed. Belt-type sorters are also very good for this purpose. In some Green Leaf Tobacco plants, an additional sorting machine that conveys the tobacco via rotating cleaning rollers is located upstream of the optical sorters. Non-tobacco related materials are caught and removed here. The tobacco leaves are also separated further, which makes it easier for the optical sorters and increases their efficiency.
