背景技术Background technique
造纸法再造烟叶(Paper-process reconstituted tobacco)又称为烟草薄片，是采用现代提取分离工艺与改良后的造纸技术，将烟草副产品及废弃料加工而成的一种“人造烟叶”，也称造纸法再造烟叶，主要是以烟梗、碎烟及烟末等烟草加工中的废料制成的烟草浆与一定量的木浆及填料等混合经造纸机抄造成基片再经浸渍涂布而制得。Paper-process reconstituted tobacco (Paper-process reconstituted tobacco), also known as tobacco sheet, is a kind of "artificial tobacco leaf" made by processing tobacco by-products and waste materials using modern extraction and separation technology and improved papermaking technology, also known as papermaking. The reconstituted tobacco leaf is mainly made of tobacco pulp made from waste materials in tobacco processing such as tobacco stems, shredded tobacco and tobacco powder, mixed with a certain amount of wood pulp and fillers, and then copied into a substrate by a paper machine and then dipped and coated. have to.
再造烟叶起源于20世纪50年代，其发展经历了辊压法-稠浆法-造纸法3个阶段。造纸法再造烟叶与目前生产的辊压法、稠浆法再造烟叶相比具有独特的优点，包括密度小、填充值高；耐机械加工性能好，成丝率高；燃烧速度快、焦油释放量低；产品可塑性好等。Reconstituted tobacco originated in the 1950s, and its development has gone through three stages: roll pressing method-thick pulp method-papermaking method. Compared with the currently produced reconstituted tobacco leaves by the roll pressing method and the thick pulp method, the reconstituted tobacco leaves of the papermaking method have unique advantages, including low density, high filling value; good mechanical processing resistance, high filamentation rate; fast burning speed, and tar release. Low; product plasticity is good.
目前各生产企业采用的工艺略有不同，基本上是将典型的两步法略做改进，梗、末均用水萃取，萃取后的烟末烟梗经混合打浆处理后，将浆料送到抄纸机上抄造成形，两种萃取液经过浓缩等手段处理后，配制混合再涂布到薄片片基上。其主要工序包括有原料预处理、萃取、浓缩、制浆、抄造、涂布、后处理等。At present, the processes adopted by various production enterprises are slightly different. Basically, the typical two-step method is slightly improved. Both the stem and the end are extracted with water. It is formed on a paper machine, and the two extracts are processed by means of concentration, etc., and then mixed and coated on the sheet base. Its main processes include raw material pretreatment, extraction, concentration, pulping, papermaking, coating, post-processing, etc.
为了提高再造烟叶灰分含量，在生产中通常要添加一定比例的填料，进而提高再造烟叶物理性能、吸液性能及外观性能等，并且改善基片的抽吸品质。此外在再造烟叶基片抄造过程中添加填料还能降低企业生产成本，同时纤维组分的减少还能相应的降低烟气有害成分的释放。碳酸钙是造纸法再造烟叶最常规的填料，目前国内外厂家在制浆抄造过程中基本都使用碳酸钙作为填料。但是，国内的再造烟叶整体填料留着率水平与国外相比，存在着一个重要问题就是填料留着率相对来说要低得多。因此填料的使用及留着率的提高成为研究重点，如何提高填料留着率，从而改善卷烟燃烧状态以及减少有害成分含量显得非常重要。In order to increase the ash content of reconstituted tobacco leaves, a certain proportion of fillers is usually added during production, thereby improving the physical properties, liquid absorption performance and appearance performance of reconstituted tobacco leaves, and improving the smoking quality of the substrate. In addition, the addition of fillers during the manufacturing process of the reconstituted tobacco leaf substrate can also reduce the production cost of the enterprise, and at the same time, the reduction of fiber components can also reduce the release of harmful components in the smoke. Calcium carbonate is the most conventional filler for paper-making reconstituted tobacco leaves. At present, domestic and foreign manufacturers basically use calcium carbonate as filler in the pulping process. However, compared with foreign countries, the overall filler retention rate of domestic reconstituted tobacco leaves has an important problem that the filler retention rate is relatively much lower. Therefore, the use of fillers and the improvement of retention rate have become the focus of research. How to improve the retention rate of fillers, thereby improving the combustion state of cigarettes and reducing the content of harmful components is very important.
硅藻土的化学成分主要是SiO2，含有少量的Al2O3、Fe2O3、CaO、MgO等和有机质，在电子显微镜下可以观察到特殊多孔的构造，具有优良的延伸性，较高的冲击强度、拉伸强度、撕裂强度、质轻软内磨性好、搞压强度好等方面优质作用。在造纸业办公用纸、工业用纸等各种纸张，硅藻土加入能使纸张平滑，重量轻，强度好，减少因湿度变化而引起伸缩，在卷烟纸中可调节燃烧率，无任何毒性副作用，在滤纸中可提高滤液澄清度，并使滤速加快。The chemical composition of diatomite is mainly SiO2 , containing a small amount of Al2 O3 , Fe2 O3 , CaO, MgO, etc. High impact strength, tensile strength, tear strength, light and soft, good internal abrasion resistance, good compressive strength, etc. In various papers such as office paper and industrial paper in the paper industry, the addition of diatomite can make the paper smooth, light in weight, good in strength, and reduce the expansion and contraction caused by humidity changes. In cigarette paper, the combustion rate can be adjusted without any toxicity. As a side effect, the clarity of the filtrate can be improved in the filter paper, and the filtration speed can be accelerated.

本发明通过寻求一种高留着率的填料、优化填料添加工艺及比例等，以提高填料在再造烟叶产品中的留着率，进而提高再造烟叶物理性能、吸液性能及外观性能等，并且改善基片的抽吸品质。此外提高填料的留着率能减少纤维组分，不仅能降低企业生产成本，还能相应的改善卷烟燃烧状态以及降低烟气有害成分的释放。The present invention improves the retention rate of the filler in the reconstituted tobacco leaf product by seeking a filler with a high retention rate, optimizing the filler addition process and ratio, etc., thereby improving the physical properties, liquid absorption performance and appearance performance of the reconstituted tobacco leaf, and Improves the suction quality of the substrate. In addition, improving the retention rate of fillers can reduce fiber components, which can not only reduce the production cost of enterprises, but also improve the combustion state of cigarettes and reduce the release of harmful components in smoke.
作为优选，所述的烟草原料按质量百分比计，包括如下组分：烟梗40～60％，烟末，30～40％碎烟叶10～20％，烟灰0～10％。Preferably, the tobacco raw material includes the following components in terms of mass percentage: 40-60% of tobacco stems, tobacco dust, 30-40% of shredded tobacco leaves, 10-20%, and 0-10% of ash.
步骤(1)中，烟草原料与水质量比为1：2～8，萃取pH4～6，萃取温度为50～70℃，萃取时间为2～3h。In step (1), the mass ratio of tobacco raw material to water is 1:2-8, the extraction pH is 4-6, the extraction temperature is 50-70° C., and the extraction time is 2-3 hours.
作为优选，步骤(1)中，将烟末、碎烟叶和烟灰混合后加水萃取，萃取后得到混合末物料；烟梗单独加水萃取，萃取后得到烟梗物料。由于烟末、碎烟叶和烟灰中烟碱含量高，而烟梗本身含有大量果胶等一些产生刺激性和异味的成分，因此烟梗的萃取液口感会较差，分开萃取有利于根据口感需求灵活添加二者的比例。Preferably, in step (1), the tobacco powder, shredded tobacco leaves and soot are mixed and then extracted with water to obtain a mixed powder material; the tobacco stems are separately extracted with water to obtain a tobacco stem material after extraction. Due to the high content of nicotine in tobacco powder, shredded tobacco leaves and tobacco ash, and the tobacco stem itself contains a lot of pectin and other irritating and odor-generating components, the taste of the tobacco stem extract will be poor. Separate extraction is beneficial to meet the taste requirements. Add the ratio of the two flexibly.
进一步优选，步骤(2)中，混合末物料进行固液分离，分离后的固相物料进行粗磨制成混合末浆料；烟梗物料经预磨后进行固液分离，分离后的固相物料进行粗磨制成烟梗浆料。Further preferably, in step (2), the mixed end material is subjected to solid-liquid separation, and the separated solid phase material is roughly ground to make a mixed end slurry; the tobacco stem material is subjected to solid-liquid separation after pre-grinding, and the separated solid phase The material is coarsely ground to make tobacco stem slurry.
进一步优选，所述混合末浆料的打浆度为15～250SR，纤维算术平均长度为0.35～0.45mm，纤维宽度为80～90μm，纤维卷曲率为15～20％。More preferably, the beating degree of the mixed powder slurry is 15-250 SR, the arithmetic average fiber length is 0.35-0.45 mm, the fiber width is 80-90 μm, and the fiber crimp rate is 15-20%.
进一步优选，所述烟梗浆料的打浆度为15～250SR左右，纤维算术平均长度0.45～0.55mm，纤维宽度为70～80μm，纤维卷曲率为15～20％。More preferably, the beating degree of the tobacco stem pulp is about 15-250 SR, the arithmetic average fiber length is 0.45-0.55 mm, the fiber width is 70-80 μm, and the fiber crimp rate is 15-20%.

所述硅藻土的粒径为5～50μm，d50为20～30μm，表面积平均粒径D(3,2)为10～15μm。The particle size of the diatomite is 5-50 μm, the d50 is 20-30 μm, and the average particle size D(3,2) of the surface area is 10-15 μm.
所述碳酸钙的粒径为1～40μm，d50为10～20μm，表面积平均粒径D(3,2)为1～5μm。The particle diameter of the calcium carbonate is 1-40 μm, the d50 is 10-20 μm, and the average particle diameter D(3,2) of the surface area is 1-5 μm.
所选碳酸钙粒径较硅藻土小，加入高浓稳浆箱前先将硅藻土和碳酸钙按配比混合进行复配，混合时可以将部分粒径小的碳酸钙吸附在硅藻土大孔隙内，从而提高填料的整体留着比例；同时，二者按配比混合使用时不仅可以调节卷烟燃烧状态，而且还能调节卷烟抽吸口感。The particle size of the selected calcium carbonate is smaller than that of diatomite, and the diatomite and calcium carbonate are mixed according to the proportion before adding to the high-concentration slurry tank. When mixing, some calcium carbonate with small particle size can be adsorbed on the diatomite Large pores, thereby increasing the overall retention ratio of the filler; at the same time, when the two are mixed according to the ratio, they can not only adjust the combustion state of the cigarette, but also adjust the smoking taste of the cigarette.
高浓稳浆箱中的混合固相浆料经过各级磨浆后，纤维表面形态发生了变化，纤维交织在一起具有不同孔隙率分布，该粒径范围的硅藻土和碳酸钙复合填料能与之有效的吸附结合。After the mixed solid-phase slurry in the high-consistency pulp stabilization box has been refined at various stages, the surface morphology of the fibers has changed, and the fibers are intertwined with different porosity distributions. The diatomite and calcium carbonate composite fillers in this particle size range can with effective adsorption.
作为优选，加入硅藻土和碳酸钙复合填料后高速搅拌混合2～5分钟，搅拌速率为800～1500r/min，此时浆料中的纤维由于磨浆工艺处理而形成不同孔隙率，与硅藻土、碳酸钙能在水中絮聚在一起，有效的吸附结合。硅藻土主要通过筛分作用、深度效应及吸附作用3种协同作用达到助留的作用，以提高造纸法再造烟叶产品填料留着率。As a preference, after adding diatomite and calcium carbonate composite filler, stir and mix at high speed for 2 to 5 minutes, and the stirring rate is 800 to 1500r/min. At this time, the fibers in the slurry form different porosity due to the refining process, and the silicon Algae earth and calcium carbonate can be flocculated together in water for effective adsorption and combination. Diatomaceous earth achieves the effect of retention mainly through three synergistic effects of sieving effect, depth effect and adsorption effect, so as to improve the filler retention rate of papermaking reconstituted tobacco leaf products.
作为优选，步骤(3)中，所述涂布液的涂布量为浆料绝干量的35～40％。Preferably, in step (3), the coating amount of the coating liquid is 35-40% of the dry weight of the slurry.
与现有技术相比，本发明的有益效果在于：Compared with prior art, the beneficial effect of the present invention is:
