Abstract: In order to lower the temperature of circulating air in fluidized bed of ZJ116 cigarette maker, the circulating fan was modified via CREO parametric design. The temperature in the air distribution chamber was effectively lowered by way of adopting a water cooling fan and supplementing cool air at the air inlet of fan, so that the air temperature in fluidized bed was lowered accordingly. The cigarette brand "Liqun" was tested on ZJ116 and ZJ17 cigarette makers, the results showed that:1) The temperature in air distribution chamber of ZJ116 cigarette maker lowered from 42.23 to 36.41℃, which satisfied the process temperature requirements. 2) The sensory quality of cigarettes from ZJ116 was basically close to that from ZJ17, it unified the sensory quality of cigarettes coming from high speed and medium speed cigarette makers. This method provides a technical support for promoting the production performance of high speed cigarette maker.
