Influences of the Controlled Strand Length Cutting of Tobacco Strips on the Quality Characteristics of Cigarette

PurposeTo investigate the influence of the controlled strand length cutting of tobacco strips on the quality characteristics of cigarette, ensure the quality and stability of cigarette products.

MethodWhen the width of cut wire was uniform to 1.0 mm, the influences of different length of cut tobacco including flat blade, pitch 50 mm, pitch 40 mm, pitch 30 mm on the structure of cut tobacco, chemical components, quality characteristics, combustion state and sensory quality of cigarette were studied.

ResultsAs the pitch of the cutter blade decreases, the proportion of filament and middle-silk in cut tobacco was more balanced, the structure of tobacco was more uniform. There was no significant difference in the conventional chemical composition of dried tobacco of four lengths of cut tobacco. The uniformity of cigarette density and the stability of cigarette physical indicators were better than those of uncontrolled cut tobacco length. The control length of tobacco had a great effect on the maximum solid temperature of cigarette combustion, and had little effect on the burning rate of cigarette. The control length of different cut tobacco had great influence on the sensory quality of cigarette products, order of sensory quality was: pitch 50 mm>pitch 40 mm>pitch 30 mm>flat blade.

ConclusionProper control of cut length can effectively improve the quality stability and smoking quality of cigarette products.
