Application of a New Screw Type Cut Tobacco Distributor in Pneumatic Feeding System

Abstract

To solve the problems such as cut tobacco segregation and high fine content and improve the control precision and stability in pneumatic feeding system, a new screw type cut tobacco distributor featuring a tobacco sieve and laterally fed was tested. The results showed that: the mentioned problems were solved effectively, whereby the structure of cut tobacco improved obviously. The proportions of medium to short strands increased by 2.41% and that of long strands by 2.34%, respectively; the small particle content reduced by 1.55%; the filling power increased by 0.12 cm3/g; the standard deviations of individual weight and draw resistance of cigarettes reduced by 4 mg/cig. and 32 Pa/cig., respectively; the tobacco loss from cigarette ends, fine content, deliveries of tar and CO averagely reduced by 1.23 mg/cig., 0.42%, 0.16 mg/cig.and 0.28 mg/cig., respectively. And the smoking quality improved steadily.
