Abstract

In order to reveal the impact of fouling formation in the thin-plate cut tobacco dryer on the equipment process performance, a thickness detector combined with mathematical statistical analysis and thermal imaging analysis techniques was employed to comparatively analyze the differences in fouling severity, batch-to-batch operational values of process parameters, stability of hot air control, material tail delay characteristics, and steam consumption between two cut tobacco dryers. The results indicated that the average thicknesses of the fouling layers on the walls of the two dryers were 1.5 mm and 0.4 mm, respectively. Dryers with varying degrees of fouling exhibited significant differences in the operational values of material flow rate and process hot air flow rate between batches. Compared to the dryer with a fouling layer thickness of 0.4 mm, when the wall fouling thickness was 1.5 mm, fluctuations in the process hot air flow and temperature of the dryer were increased, resulting in a 30 s increase in material tail delay and a 65 kg/h increase in steam consumption. The adhesion and accumulation of particulate fouling on the walls affected the uniformity of the drum wall temperature distribution, with local temperature extremes reaching 8 ℃.
