本发明涉及造纸法再造烟叶领域，特别是涉及一种利用加填新型填料硅藻土来提高造纸法再造烟叶产品性能的方法。The invention relates to the field of papermaking reconstituted tobacco leaves, in particular to a method for improving the performance of papermaking reconstituted tobacco products by adding a new type of filler diatomite.
背景技术Background technique
随着近年来造纸法再造烟叶对改善烟支结构、降焦减害等方面的积极作用日益凸显，目前造纸法再造烟叶已成为中式卷烟重要而不可或缺配方原料。目前造纸法再造烟叶都采用“两步法”生产工艺，即碎烟梗、烟片和烟末以不同比例混合后加水在一定条件下萃取，在萃取过程中，物料中一些重要化学组分溶于水，萃取完成后料液经机械挤压固液分离，固相物经造纸工艺制得烟草片基，水溶物经浓缩制成涂布液，经涂布工序涂布液再回涂于片基，最后经干燥、分切制得再造烟叶成品，又称烟草薄片。With the positive effect of papermaking reconstituted tobacco on improving cigarette structure, tar reduction and harm reduction has become increasingly prominent in recent years, papermaking reconstituted tobacco has become an important and indispensable formula raw material for Chinese-style cigarettes. At present, the reconstituted tobacco leaves of the papermaking method adopt the "two-step method" production process, that is, the crushed tobacco stems, tobacco flakes and tobacco powder are mixed in different proportions and then extracted with water under certain conditions. During the extraction process, some important chemical components in the materials are dissolved. In water, after the extraction is completed, the material liquid is separated from the solid and liquid by mechanical extrusion, the solid phase is made into a tobacco sheet base through the papermaking process, the water-soluble matter is concentrated to make a coating liquid, and the coating liquid is then coated on the sheet after the coating process base, and finally dried and cut to obtain the finished reconstituted tobacco leaf, also known as tobacco sheet.
因为再造烟叶的食用特殊性，对生产中选用的填料要求很高，目前大部分造纸法再造烟叶生产厂家均采用碳酸钙作为填料，但其留着率很低，影响产品总留着率和性能。为了进一步提高造纸法再造烟叶总留着率和产品性能，本专利选用硅藻土替代碳酸钙作为填料应用于造纸法再造烟叶中。Due to the particularity of eating reconstituted tobacco leaves, the requirements for the fillers used in production are very high. At present, most manufacturers of reconstituted tobacco leaves by papermaking method use calcium carbonate as filler, but its retention rate is very low, which affects the total retention rate and performance of the product. . In order to further improve the total retention rate and product performance of reconstituted tobacco leaves by papermaking method, diatomite is used in this patent instead of calcium carbonate as a filler to be used in reconstituted tobacco leaves by papermaking method.
硅藻土是一种类似白垩的软质状粉末，作为填料广泛应用于牙膏、医药、造纸等方面，可赋予产品新的功能与特性。其独特的孔隙结构及吸附性可吸附液体中的固体颗粒、悬浮物、胶体粒子及细菌，起到滤清和净化液体的作用，很多食品行业如啤酒业、医药行业、净水过滤、糖类、酒类等多用硅藻土作为助留助滤剂净化产品。Diatomaceous earth is a soft powder similar to chalk. It is widely used as a filler in toothpaste, medicine, papermaking, etc., and can endow products with new functions and characteristics. Its unique pore structure and adsorption can absorb solid particles, suspended matter, colloidal particles and bacteria in the liquid, and play the role of filtering and purifying the liquid. Many food industries such as beer industry, pharmaceutical industry, water purification filtration, sugar, Diatomaceous earth is often used as a retention and drainage aid to purify products such as wine.
硅藻土依其独特的孔隙结构和吸附性，在卷烟工业中常被用于卷烟纸和滤嘴中，硅藻土加填卷烟纸可提高纸张透气度，调节燃烧速度，显著降低卷烟中的焦油和其它对人体有害的物质含量。专利CN1393185A、CN201403495Y中介绍在过滤嘴中加硅藻土可显著降低卷烟焦油释放量；专利CN150213A、CN101133212A中介绍在造纸中加入硅藻土能吸附细小物质，实现留着和滤水的改进；专利CN101343843A中介绍使用硅藻土能提高废纸制浆封闭生产用水的质量；专利CN102276093A中介绍了硅藻土能吸附浆料中细小纤维、黏性物质、悬浮物质等澄清、净化液体，改善造纸法烟草薄片废水。Due to its unique pore structure and adsorption, diatomite is often used in cigarette paper and filters in the cigarette industry. Diatomite filling cigarette paper can improve the air permeability of the paper, adjust the burning speed, and significantly reduce the tar in cigarettes. and other substances harmful to the human body. Patents CN1393185A and CN201403495Y introduce that adding diatomaceous earth to the filter tip can significantly reduce the amount of tar released from cigarettes; patents CN150213A and CN101133212A introduce that adding diatomaceous earth in papermaking can absorb fine substances and achieve retention and improvement of water filtration; patent CN101343843A It is introduced that the use of diatomite can improve the quality of closed production water for waste paper pulping; the patent CN102276093A introduces that diatomite can absorb fine fibers, viscous substances, suspended substances in the slurry, etc. to clarify and purify liquids, and improve the papermaking process. flake wastewater.
从硅藻土在卷烟纸和滤嘴中的应用，可视其在造纸法再造烟叶中具有很好安全性；硅藻土在造纸中对留着率的改善作用可借鉴到造纸法再造烟叶中，以提高产品总留着率。From the application of diatomite in cigarette paper and filters, it can be seen that it has good safety in reconstituted tobacco leaves by papermaking method; the improvement of retention rate of diatomite in papermaking can be used for reference in reconstituted tobacco leaves by papermaking method , to increase the total product retention rate.
