本发明涉及卷烟技术领域，具体地说是一种可提升卷烟灰烬白度的梗丝处理方法。The invention relates to the technical field of cigarettes, in particular to a method for processing cut stems which can improve the whiteness of cigarette ashes.
背景技术Background technique
近年来随着消费者对卷烟品质追求的提高，设计者开始在一些卷烟细节上进行优化，卷烟灰烬白度就是其中之一。一般说到烟灰的白度，大体可以分成两种，一种是灰柱白度，即卷烟燃烧后呈现的柱状灰烬的外表面白度；另一种这是烟丝灰烬白度，即内部烟丝燃烧后，剥离卷烟纸灰烬后呈现的烟丝燃烧灰烬的白度。卷烟的灰柱白度主要是与卷烟纸的燃烧性质以及其与烟丝的匹配性有关；而烟丝灰烬白度则主要取决于烟丝的配方结构和添加剂。In recent years, with the improvement of consumers' pursuit of cigarette quality, designers have begun to optimize some cigarette details, and ash whiteness of cigarettes is one of them. Generally speaking, the whiteness of soot can be roughly divided into two types, one is the whiteness of the ash column, that is, the whiteness of the outer surface of the columnar ash after the cigarette is burned; , the whiteness of the tobacco burning ash after peeling off the cigarette paper. The ash column whiteness of cigarettes is mainly related to the combustion properties of the cigarette paper and its matching with the cut tobacco; the ash whiteness of the cut tobacco mainly depends on the formula structure and additives of the cut tobacco.
虽然在烟丝中加入一些功能性添加剂能够改善烟丝灰烬的白度，但往往会带来一些不可预知的安全性隐患，因此很少会被使用。Although adding some functional additives to cut tobacco can improve the whiteness of cut tobacco ash, it often brings some unpredictable safety hazards, so it is rarely used.
此外，由于梗丝结构致密，燃烧时容易爆裂，影响卷烟包灰性，一般不会直接在烟丝配方中使用。膨胀梗丝虽然能够大幅度降低爆裂的情况，但由于其中含有的果胶等不易燃成分含量仍然高，也使其燃烧灰烬普遍较黑，导致了卷烟灰烬变黑，影响了消费者的消费体验。In addition, due to the dense structure of cut stems, it is easy to burst when burning, which affects the ash-packing properties of cigarettes, so it is generally not used directly in the cut tobacco formulation. Although the expanded cut stems can greatly reduce the bursting situation, the content of non-flammable components such as pectin is still high, and the burning ash is generally darker, which leads to the blackening of the cigarette ashes and affects the consumption experience of consumers. .
为了解决以上问题，提出本发明。In order to solve the above problems, the present invention has been proposed.
发明内容SUMMARY OF THE INVENTION
本发明即是对常规的梗丝(即已经切丝成型的膨胀梗丝)进行处理，使其在兼顾加工强度的前提下增加其燃烧灰烬白度，解决卷烟灰烬发黑的问题。本发明通过对梗丝进行洗提后再修复，改善梗丝的燃烧性，并修复其耐加工强度，使其能够在正常卷烟生产过程中顺利加入到卷烟中使用。The present invention is to process the conventional cut stems (that is, the expanded cut stems that have been cut and formed), so that the whiteness of burning ash can be increased on the premise of taking into account the processing strength, and the problem of blackening of cigarette ash can be solved. The invention improves the combustibility of the cut stems and restores the processing resistance strength by eluting the cut stems and then repairing them, so that the cut stems can be smoothly added to the cigarettes for use in the normal cigarette production process.
本发明中的凝灰指数统一指的是卷烟纸灰分裂痕部分面积与整体面积的比值乘以100所得数值。如灰分裂痕部分面积占整体面积的5.0％，则凝灰指数为5.0。也就是说，凝灰指数越高，卷烟纸的包灰性能越差。The tuff index in the present invention uniformly refers to the value obtained by multiplying the ratio of the partial area of the ash splitting marks to the overall area of the cigarette paper by 100. If the partial area of ash cracks accounts for 5.0% of the total area, the tuff index is 5.0. That is to say, the higher the tuff index, the worse the ash-packing performance of the cigarette paper.
本发明第一方面提供一种可提升卷烟灰烬白度的梗丝处理方法，其包括以下步骤：A first aspect of the present invention provides a method for processing cut stems that can improve the whiteness of cigarette ashes, comprising the following steps:
(1)对梗丝进行洗提处理；(1) Elution treatment of cut stems;
(2)采用修复剂修复洗提处理后的梗丝，以恢复梗丝耐加工强度。(2) Repairing the cut stems after the elution treatment with a repairing agent to restore the processing-resistant strength of the cut stems.
优选地，步骤(1)中，首先对梗丝进行浸渍；然后采用气流干燥的工艺对洗提后梗丝进行干燥，基于质量百分比，使梗丝含水率控制在20％以内。更优选地为在8-10％范围内。Preferably, in step (1), firstly, the cut stems are dipped; then the washed cut stems are dried by the air drying process, and the moisture content of the cut stems is controlled within 20% based on the mass percentage. More preferably it is in the range of 8-10%.
优选地，步骤(1)中，梗丝在洗提液中浸渍，对浸渍后的梗丝进行洗提过滤，加入洗提液量为梗丝完全没入洗提液中为准，洗提液温度为40-60℃；浸渍时间为20-40min，洗提2-3次；干燥温度为100-120℃。洗提液温度过高或浸渍时间过长会导致梗丝结构破坏严重，后续工艺中的造碎率大幅度上升；洗提液温度过低或浸渍时间过短，则又会导致洗提不充分，对白度的改善幅度有限。其中洗提液为水或有机溶剂，该有机溶剂指现有技术常用的清洗溶剂，例如乙醇。Preferably, in step (1), the cut stems are immersed in the eluent, and the dipped cut stems are eluted and filtered, and the amount of the eluent added is that the cut stems are completely submerged in the eluent, and the temperature of the eluent is the criterion. The temperature is 40-60℃; the immersion time is 20-40min, the elution is 2-3 times; the drying temperature is 100-120℃. If the temperature of the eluent is too high or the soaking time is too long, the structure of the cut stems will be seriously damaged, and the crushing rate in the subsequent process will increase greatly; if the temperature of the eluent is too low or the soaking time is too short, it will lead to insufficient elution. , the improvement in whiteness is limited. The eluent is water or an organic solvent, and the organic solvent refers to a cleaning solvent commonly used in the prior art, such as ethanol.
优选地，步骤(2)中，将洗提并干燥后的梗丝传送入旋转滚筒内，在不断旋转的情况下在烟梗表面喷洒入一定量的修复剂，然后进行一定时间的减压平衡扩散，以恢复梗丝耐加工强度；所述修复剂选自丙三醇或者丙二醇。Preferably, in step (2), the stripped and dried cut stems are transferred into a rotating drum, and a certain amount of repairing agent is sprayed on the surface of the tobacco stems under the condition of continuous rotation, and then a certain period of decompression balance is carried out. Diffusion to restore processing strength of cut stems; the repairing agent is selected from glycerol or propylene glycol.
优选地，步骤(2)中，修复剂加入量为梗条质量的5％-15％。修复剂量过小则无法达到充分修复的效果；过大则会使梗丝过于湿润，不利于后续生产。Preferably, in step (2), the amount of the repairing agent added is 5%-15% of the quality of the stem. If the repair dose is too small, the effect of full repair cannot be achieved; if the repair dose is too large, the cut stems will be too wet, which is not conducive to subsequent production.
优选地，步骤(2)中，减压平衡扩散的压力控制在400mbar-800mbar，压力过大则丙三醇或者丙二醇分子不易充分扩散；过小又容易产生雾化，不利于丙三醇或者丙二醇分子对梗丝内部的渗入。减压平衡扩散时间为20-40min。时间过短则扩散不充分，无法完全平衡；过长则平衡扩散已基本完成，作用不大，造成时间和能耗的浪费。Preferably, in step (2), the pressure of decompression equilibrium diffusion is controlled at 400mbar-800mbar. If the pressure is too large, the glycerol or propylene glycol molecules are not easy to fully diffuse; if the pressure is too small, it is easy to produce atomization, which is not conducive to glycerol or propylene glycol. Penetration of molecules into the interior of cut stems. The equilibrium diffusion time under reduced pressure is 20-40min. If the time is too short, the diffusion will not be sufficient and cannot be completely balanced; if the time is too long, the equilibrium diffusion will be basically completed, and the effect will not be large, resulting in a waste of time and energy consumption.
此处，本发明修复过程中选用的是减压平衡扩散，相对于烟丝来讲，梗丝自身较硬，结构致密，不利于进行洗提和修复，如果仅是在烟梗表面喷洒入修复剂后自然扩散，修复剂仅能停留在烟梗表面，无法达到烟梗内部，对于梗丝柔韧性的提升并不明显，从而导致不能有效的降低造碎，相对于自然扩散，采用减压平衡扩散更利于降低造碎率，提升卷烟灰烬白度。Here, in the repair process of the present invention, decompression balance diffusion is selected. Compared with cut tobacco, the cut stem itself is hard and has a dense structure, which is not conducive to elution and repair. If only a repair agent is sprayed on the surface of the tobacco stem After natural diffusion, the repair agent can only stay on the surface of the tobacco stems and cannot reach the interior of the tobacco stems. The improvement of the flexibility of the cut stems is not obvious, which leads to the inability to effectively reduce fragmentation. Compared with natural diffusion, the use of decompression balance diffusion It is more conducive to reducing the breaking rate and improving the whiteness of cigarette ash.
本发明第二方面提供一种本发明第一方面所述的梗丝处理方法处理的梗丝的用途，其特征在于，将其用于卷烟中，可以提升卷烟灰烬白度15-30个单位，降低凝灰指数1-2个单位。The second aspect of the present invention provides a use of the cut stems treated by the cut stem treatment method according to the first aspect of the present invention, characterized in that, when the cut stems are used in cigarettes, the ash whiteness of the cigarettes can be increased by 15-30 units, Decrease the tuff index by 1-2 units.
相对于现有技术，本发明具有以下有益效果：Compared with the prior art, the present invention has the following beneficial effects:
1、卷烟灰烬白度改善明显：使用该梗丝制造的卷烟，按标准方法检测其灰烬白度，发现普遍能够提升灰烬白度15-30个单位。1. The ash whiteness of cigarettes is obviously improved: the ash whiteness of cigarettes made by using the cut stems is tested according to the standard method, and it is found that the ash whiteness can generally be improved by 15-30 units.
2、凝灰指数改善：由于该梗丝的燃烧性改善，卷烟烟丝燃烧后产生的收缩明显，卷烟纸裂口率大幅度下降，使用该卷烟纸制造的卷烟，按标准方法检测其凝灰指数，发现其凝灰指数普遍能够降低1-2个单位。2. Improvement of tuff index: due to the improvement of the flammability of the cut stems, the shrinkage of the cigarette shreds after burning is obvious, and the crack rate of the cigarette paper is greatly reduced. It was found that the tuff index was generally able to be reduced by 1-2 units.
3、卷烟感官品质变化较小且无安全隐患：由于梗丝在烟气感官贡献中占比较小，因此影响有限，且由于未加入新的添加剂，无安全隐患。3. Small changes in the sensory quality of cigarettes and no potential safety hazards: Since cut stems account for a small proportion of the sensory contribution of smoke, the impact is limited, and because no new additives are added, there are no potential safety hazards.
4、造碎率小：本发明对梗丝浸渍洗提后，对其进行修复处理，以修复其耐加工强度，大幅度降低造碎率，采用本发明方法处理提升卷烟灰烬白度的工艺造碎率能够控制在10-20％以内，节约生产成本。本发明针对于梗丝提供了具体的洗提和修复方法，相对于烟丝来讲，梗丝自身较硬，结构致密，不利于进行洗提和修复，尤其是在修复过程中，本发明在梗丝上喷洒丙三醇或者丙二醇后，进行一定时间的减压平衡扩散，其中，减压平衡扩散的压力控制在400mbar-800mbar，压力过大则丙三醇或者丙二醇分子不易充分扩散；过小又容易产生雾化，不利于丙三醇或者丙二醇分子对梗丝内部的渗入。减压平衡扩散时间为20-40min。时间过短则扩散不充分，丙三醇或者丙二醇无法向梗条内部渗入；过长则平衡扩散已基本完成，作用不大，造成时间和能耗的浪费。在该条件下不仅可以明显提高梗丝的耐加工强度，还能避免对梗丝内部的化学成分造成影响，避免了对梗丝耐加工性能修复后，还要针对化学成分的不同进行微调。相对于单独喷洒后自然扩散，采用本发明方法对梗丝进行修复，提升卷烟灰烬白度的工艺的造碎率更低，且卷烟灰烬白度提升更加明显。单独喷洒后自然扩散，提升卷烟灰烬白度的工艺的造碎率为20-30％左右。如果仅是在梗丝表面喷洒入修复剂后自然扩散，修复剂仅能停留在梗丝表面，无法达到梗丝内部，对于梗丝柔韧性的提升并不明显，从而导致不能有效的降低造碎。相对于自然扩散，采用减压平衡扩散更利于降低造碎率，提升卷烟灰烬白度。4. The crushing rate is small: after the dipping and elution of the cut stems in the present invention, it is repaired to restore its processing-resistant strength and greatly reduce the crushing rate. The broken rate can be controlled within 10-20%, saving production costs. The invention provides a specific elution and repair method for cut stems. Compared with cut tobacco, cut stems are hard and dense in structure, which is not conducive to elution and repair. After spraying glycerol or propylene glycol on the silk, a certain period of decompression equilibrium diffusion is carried out, wherein the pressure of decompression equilibrium diffusion is controlled at 400mbar-800mbar. It is easy to produce atomization, which is not conducive to the penetration of glycerol or propylene glycol molecules into the inside of cut stems. The equilibrium diffusion time under reduced pressure is 20-40min. If the time is too short, the diffusion will be insufficient, and glycerol or propylene glycol cannot penetrate into the stem; if the time is too long, the equilibrium diffusion will be basically completed, and the effect will not be large, resulting in a waste of time and energy consumption. Under this condition, not only can the processing resistance strength of cut stems be significantly improved, but also the chemical composition inside the cut stems can be avoided, and the fine-tuning of the chemical composition after the processing resistance performance of cut stems can be avoided. Compared with the natural diffusion after spraying alone, the method of the present invention is used to repair the cut stems, and the process of improving the whiteness of cigarette ash has a lower breaking rate, and the improvement of the whiteness of cigarette ash is more obvious. After being sprayed alone, it spreads naturally, and the shredding rate of the process of improving the whiteness of cigarette ash is about 20-30%. If the repair agent is only sprayed on the cut stem surface and then spreads naturally, the repair agent can only stay on the surface of the cut stem and cannot reach the inside of the cut stem. The improvement of the flexibility of the cut stem is not obvious, resulting in an ineffective reduction of fragmentation. . Compared with natural diffusion, balanced diffusion under reduced pressure is more conducive to reducing the fragmentation rate and improving the whiteness of cigarette ash.
5、在减压扩散前梗丝含水率在20％以内，优选地，所述梗丝在气流干燥后的含水率控制在8-10％范围内，其目的在于，含水率过高会导致减压扩散后的梗丝过湿，需要进一步除去水分才能使用，含水率过低，则会在之前的干燥过程中就会产生大量造碎。5. The moisture content of cut stems before decompression and diffusion is within 20%. Preferably, the moisture content of the cut stems after air drying is controlled within the range of 8-10%. The cut stems after pressure diffusion are too wet and need to be further removed to be used. If the moisture content is too low, a lot of breakage will occur in the previous drying process.

整个该梗丝的处理工艺流程如附图1所示。The whole process flow of the cut stems is shown in Figure 1 .
另外，本实施例中卷烟灰烬白度采用常规粉末白度检测方法进行检测所得，凝灰指数按前述方法进行计算。In addition, in this embodiment, the ash whiteness of the cigarettes is obtained by using the conventional powder whiteness detection method, and the tuff index is calculated according to the aforementioned method.
对比例1Comparative Example 1
在常规的膨胀梗丝中加入40℃温水浸渍后过滤，浸渍时间为30min，再重复浸渍一次后，采用气流干燥的工艺对梗丝进行干燥，使其含水率控制在8％左右。将洗提并干燥后的梗丝传送入旋转滚筒内，在不断旋转的情况下并喷洒入梗丝质量5％的甘油后，自然扩散60min后取出，即为本发明所述的可提升卷烟灰烬白度的梗丝产品。Add 40°C warm water to the conventional expanded cut stems and filter them for immersion for 30 minutes. After repeating the dipping once, the cut stems are dried by air drying process to control the moisture content at about 8%. The stripped and dried cut stems are transported into the rotating drum, sprayed into the glycerin of 5% of the cut stem mass under the condition of continuous rotation, naturally diffused for 60 minutes and taken out, that is, the cigarette ashes can be lifted according to the present invention. Whiteness of cut stem products.
采用上述方法得到的梗丝造碎率为27％左右。采用该梗丝按原配方中的比列与无梗烟丝制成卷烟(2#)，并与原卷烟(1#)进行对比，结果如下：The shredding rate of cut stems obtained by the above method is about 27%. The shredded stem was used to make cigarette (2#) with shredded tobacco according to the ratio in the original formula, and compared with the original cigarette (1#), the results are as follows:
从上表中可以看出，对比原卷烟样品，采用处理后梗丝生产的卷烟灰烬白度和凝灰指数均得到些许改善。As can be seen from the table above, the ash whiteness and tuff index of the cigarettes produced with the treated cut stems were slightly improved compared to the original cigarette samples.
实施例1Example 1
在常规的膨胀梗丝中加入40℃温水浸渍后过滤，浸渍时间为30min，再重复浸渍一次后，采用气流干燥的工艺对梗丝进行干燥，使其含水率控制在8％左右。将洗提并干燥后的梗丝传送入旋转滚筒内，在不断旋转的情况下并喷洒入梗丝质量5％的甘油后，在400mbar下减压平衡扩散40min后取出即为本发明所述的可提升卷烟灰烬白度的梗丝产品。Add 40°C warm water to the conventional expanded cut stems and filter them for immersion for 30 minutes. After repeating the dipping once, the cut stems are dried by air drying process to control the moisture content at about 8%. The eluted and dried cut stems are transferred into a rotating drum, sprayed into glycerin with 5% mass of cut stems under the condition of constant rotation, and taken out after 40min under reduced pressure and equilibrium diffusion at 400 mbar, which is the method described in the present invention. Cut stem products that enhance the whiteness of cigarette ashes.
采用上述方法得到的梗丝造碎率为12％左右。采用该梗丝按原配方中的比列与无梗烟丝制成卷烟(2#)，并与原卷烟(1#)进行对比，结果如下：The cutting rate of cut stems obtained by the above method is about 12%. The shredded stem was used to make cigarette (2#) with shredded tobacco according to the ratio in the original formula, and compared with the original cigarette (1#), the results are as follows:
从上表中可以看出，对比原卷烟样品，采用处理后梗丝生产的卷烟灰烬白度和凝灰指数均显著改善。As can be seen from the above table, compared with the original cigarette samples, the ash whiteness and tuff index of the cigarettes produced with the treated cut stems were significantly improved.
对比上述对比例1，采用本发明方法处理后的梗丝对卷烟灰烬白度和凝灰指数的影响更为显著，原因可能在于，减压扩散工艺能够使甘油向内部的渗透更为显著，从而使相同量的甘油在梗丝中的分布更加均匀，从而降低了部分位置由于甘油浓度过高而导致燃烧不充分，灰烬发黑、凝灰指数不好的情况。除此之外，相对于自然扩散，采用减压平衡扩散更利于降低造碎率。Compared with the above-mentioned comparative example 1, the cut stems treated by the method of the present invention have more significant effects on the ash whiteness and tuft index of cigarettes. The distribution of the same amount of glycerin in the cut stems is more uniform, thereby reducing the situation of insufficient combustion, black ash and poor tuft index in some positions due to excessive glycerin concentration. In addition, compared with natural diffusion, the use of reduced pressure equilibrium diffusion is more conducive to reducing the fragmentation rate.
