摘要：为了解决再造烟叶企业生产的浆料较差、分丝帚化率低、过度切断纤维、浆料稳定性差、浆料得率低和产品物理指标波动大等问题，试验结合原料特点和制浆技术，对原有的磨浆机磨片进行改进，并改进原有的制浆工艺，提出了一种适用于再造烟叶生产的柔性制浆技术。通过对比，分析了柔性制浆技术前后的制浆工艺及该技术应用前后的浆料纤维形态，分析了柔性制浆技术的特点，此工艺提高了浆料品质，在保证产品松厚度和抗张强度等物理指标稳定的条件下，为生产运行车速从现在的平均80 m/min提高到平均165 m/min以上提供了技术支撑，实现了原料的精细化加工及加工过程的可控可调。

Abstract： In order to solve the paper-process reconstituted tobacco company of pulp is poorer， the rate of fibrous fibrillating is low， too much to cut off the fiber length， poor pulp stability， low pulp yield and big fluctuation of product physical index. This paper combines with the characteristics of raw materials and pulping technology， to improve the original pulping machine grinding， and to improve the original pulping process， put forward a kind of suitable for paper-process reconstituted tobacco production flexible pulping technology. Before and after the contrast analysis of the flexible pulping technology of pulping process， fiber morphology before and after flexible pulping technology application， and analyses the characteristics of flexible pulping technology， and improve the pulp quality. The guarantee product thickness and tensile strength of physical indexes such as stability conditions， and for the production run speed increased from now an average of 80 m/min to more than an average of 165 m/min provides technical support， and implements the fine process of raw material and machining process of controllable is adjustable.

目前，國内的再造烟叶生产企业大都采用高浓打浆工艺，其流程相对较短，且原料差异性大，因此所生产的浆料均匀性差[1-3]。为了保证产品质量，宜根据各自的纤维特性及需要达到的指标采取不同的制浆方法，不同制浆方法对再造烟叶产品有不同的影响，如与高浓打浆相比，低浓打浆的浆料中烟草纤维自身的长度保留良好，因而匀度较好，同时其抗张强度提高；但纤维内部细纤维不足、柔软度略有降低，留着率降低，影响制浆得率，且耗水大，因此，高浓打浆和低浓打浆各有利弊[4-6]。再造烟叶产品一般要求具有较适宜的松厚度，以保证后续……
