造纸法再造烟叶原料的打浆性能

Performance of Raw Material Beating in Paper-making Process Reconstituted Tobacco Production

以PFI(Pulp Refiner)磨为打浆设备,采用正交试验的方法,分别研究了打浆设备参数(打浆间隙、打浆时间)和浆料浓度对烟末和烟梗打浆功率、浆料质量(浆料叩解度、湿重)的影响。结果表明:1烟末和烟梗浆打浆过程中浆料浓度对打浆功率影响较大,打浆设备参数对浆料质量的影响较大;2随着打浆间隙上升,烟末和烟梗浆的叩解度都不同程度地下降,同时湿重也相应上升;烟末浆打浆功率受打浆时间变化的影响很小,而烟梗浆在打浆初期打浆功率偏高;浆料浓度增加,烟末浆叩解度下降,而烟梗浆叩解度变化不大,同时烟末和烟梗浆湿重随浆料浓度增加变化均不明显。

By adopting PFI （Pulp Refiner） for beating tobacco dust and stem,the influences of beating parameters （beating clearance and beating duration） and pulp concentration on the beating power and pulp quality （Sehopper-Riegler degree and wet weight） were investigated with orthogonal experiments.The results showed that：1）Beating power was obviously affected by pulp concentration,as did pulp quality by beating parameters.2）With the increase of beating clearance,the Schopper-Riegler degree of tobacco dust and stem pulp decreased to different extents,while the wet weight increased.The variation of beating time did not affect the power consumption for tobacco dust beating obviously,however,the power consumption for tobacco stem beating was slightly higher at initial stage.3）With the increase of pulp consistency,the Schopper-Riegler degree of tobacco dust pulp declined,while that of tobacco stem pulp and the wet weight of tobacco dust and stem pulp did not changed obviously.
