Effects of fluidized bed temperature parameters on manufacturing quality in ZJ116B high-speed cigarette maker

This study quantifies how elevated temperatures in the fluidized-bed feeding system of the ZJ116B fine-cut high-speed cigarette maker (10 000 cigarettes min⁻¹) influence cigarette quality. Continuous high-speed operation raised bed-surface temperature to ≈ 47°C and circulation-fan temperature to ≈ 56°C. These increases were strongly correlated with a decline in cut-tobacco integrity, higher breakage rates, lower moisture content, and deteriorated physical indices (tobacco powder, loose ends, end loss, weight SD and draw-resistance SD). Converting the original closed-loop airflow to an open-loop configuration, which draws ambient air and exhausts into the workshop dust-removal system, lowered bedsurface and fan temperatures by ≈ 17°C and ≈ 24°C, respectively. The cooler operating conditions increased intactstrand rate and moisture content, while simultaneously reducing broken-strand rate, tobacco powder, loose ends, end loss, weight SD and draw-resistance SD. The results demonstrate that controlling fluidized-bed temperature effectively curbs moisture loss and mechanical damage, thereby improving the physical consistency of slim cigarettes.
