Development and Application of On-line Tobacco Recycling System in ZJ17 Cigarette Maker

To avoid cut tobacco escaping into centralized dusting system from rod forming section in ZJ17 cigarette maker and reduce tobacco consumption,an on-line tobacco recycling system was designed by referring to the working principle of tangential separator in threshing machine.The system adopted two-stage pneumatic separation:the first stage was a cyclone separator to separate the suspended matter from dusting airflow,the second stage to separate cut tobacco from tobacco dust.The separated cut tobacco was on-line reclaimed and returned to the feeding system of cigarette maker.The results of application showed that the cigarette weight,draw resistance and amount of tobacco loss from cigarette ends of three tested cigarette brands were all up to the technical standards,the average tobacco recovery was 9.34 kg/shift,the recovery rate reached 81.4%.
