摘　　要：为解决在传统CO2膨胀烟丝加工过程中,升华后的膨胀烟丝耐加工性差、造碎大等问题,采用蒸汽预回潮工艺,在升华器后增设了蒸汽喷射预回潮出料装置。该装置既有蒸汽预回潮功能又能保证正常出料,蒸汽经过均匀分布的加湿喷管释放到气锁刮板的腔体内,把经过转网分离进入出料气锁刮板内的膨胀烟丝均匀加湿,并对物料进行松散。应用效果表明,采用预回潮工艺进行设备改造后,膨胀烟丝整丝率提高1.5百分点,出丝率提高0.75百分点,避免了在加湿过程中产生水渍烟丝,有效提高了膨胀烟丝的耐加工性,降低了烟丝造碎。Aiming at the problems of high breakage and poor processing durability of expanded cut tobacco by traditional CO2 expanded cut tobacco processing, a steaming preconditioning discharger was added next to the expansion tower, which moistened the tobacco as it left the tower. Steam was injected into the compartments in the airlock discharger through uniformly distributed nozzles, to allow the tobacco entering into the airlock being evenly humidified and loosed. The results of application showed that after improvement, the percentage of long strands and cut tobacco yield increased by 1.5 and 0.75 percentage points, respectively. Water stained tobacco was avoided in the process of humidifying. The processing durability of expanded cut tobacco was effectively improved, while the breakage of cut tobacco was reduced.
