Description

一种降温嘴棒及卷烟 技术领域
本发明涉及一种降温嘴棒及卷烟，属于卷烟加工制造领域。
背景技术
加热不燃烧卷烟是通过外部加热元件对烟草物质进行加热,烟丝或薄片只加热但不燃烧，烟支中的雾化介质、烟草中的香味成分和外加香物质通过加热产生烟雾，烟气中有害化学成分的释放量明显降低。目前，市场在售的主流加热不燃烧卷烟有菲莫公司的iQOS与英美烟草的glo两种产品，当两种烟支在250-350℃的加热条件下达到雾化温度后，高温雾化烟气通过滤嘴段进入口腔中的温度会高于普通卷烟燃烧的温度，从而导致入口烟气过烫，在抽吸体验与抽吸感受等方面与传统卷烟尚存在较大差距。
现有技术主要是通过相变降温材料对纵向流动的高温烟气进行降温处理，如iQOS的降温段材料主要是皱褶、打褶、聚集和折叠的聚乳酸(PLA)薄片，由于受嘴棒长度及相变降温材料的限制，同时烟气流速也比较快，导致材料降温有一定困难；过热烟气通过嘴棒时的横向传热，使得消费者抽吸时有烫嘴唇的感觉。此外，相变降温材料PLA薄片接触高温烟气后出现熔融现象，导致烟气通道堵塞，影响材料的降温效果甚至会导致烟雾量显著降低。
因此，目前急需一种可有效降低加热不燃烧卷烟烟气温度，改善烟气感官质量的降温且低过滤嘴棒及加热不燃烧卷烟，本发明解决这样的问题。
发明内容
针对现有技术的不足，本发明提供一种降温嘴棒及卷烟，以显著降低高温烟气入口温度，进一步改善和提升抽吸体验。
为了解决上述技术问题，本发明的技术方案如下：
一种降温嘴棒，包括降温段，所述降温段包括由纸张成型而成的降温棒，所述降温棒内具有若干贯通降温棒两端的孔，所述若干孔由在柱状空间内反复弯曲或曲折的纸张本身围成；所述纸张的表面涂覆有降温材料，所述降温材料的涂覆量至少为纸张总重量的15％，一般为15％-80％，进一步为 20％-70％，优选为30％-60％。
采用这样的结构设计，待降温烟气进入降温棒后与涂覆的降温材料充分接触，换热，烟气的热量转移给降温材料，烟气温度降低；另外，降温棒内具有贯通其两端的孔，吸阻小，便于烟气通过，显著降低降温棒对烟气的吸附。降温材料的涂覆量可根据降温需要选用，综合考虑降温效果、对烟气吸附效果与成本等因素，申请人反复试验发现，降温材料的涂覆量必须达到一定量，才可获得较为明显的降温且低过滤烟气的效果，降温材料涂覆量低于15％时，无法达到良好的降温、低过滤烟气的效果。
相比已有的降温嘴棒，一方面，本发明的降温棒主要由纸张制成，由于纸张的导热能力差，降温材料吸收的热量不易快速传递到抽吸端，可防止灼伤抽吸者；另一方面，尤其于加热不燃烧卷烟，无论是中心加热还是包围加热方式，前三口抽吸时均会产生大量的水蒸气，高温的水蒸气进入口腔冷凝会释放大量的热量，使得口腔的(特别是舌头)烫感明显增强，本发明的纸质降温棒具有较好的水汽吸附能力，可有效吸附水汽，提升前三口抽吸的口感，提升抽吸体验；再一方面，降温材料涂覆于纸张上后，可降低纸张相应部分对焦油等粒相物的吸附能力，故本发明的降温嘴棒对烟气中粒相物的吸附量极小，有利于提升抽吸体验；此外，本发明的降温嘴棒还具有成本优势，以降温棒的成本为例，批量化制备时，按人民币计，PLA蜂窝煤状降温棒的制作成本需要7-8分钱/个，PLA薄片降温棒的制作成本为2-3分钱/个，而本申请的降温棒的制作成本只有0.4分钱/个。
在本发明的一些实施例中，所述降温棒由纸张沿某一方向反复曲折而成。
在本发明的一些实施例中，所述降温棒由纸张无规则地反复弯曲而成，从其横截面看，纸张的走向为无规则状。
优选地，孔的数量为多个。
进一步地，所述孔的横截面为不规则状。
进一步地，所述纸张的一个或两个表面具有多条凹凸纹路，优选为褶皱形纹路。如此，可保证各孔两端始终处于连通状态，各孔有烟气流过，既可降低吸阻，又可充分发挥降温材料的降温作用，同时还能降低纸棒对烟气中粒相物的吸附。
进一步地，所述纹路的深度为0.1-3mm，优选地，相邻纹路之间的间隔为0.5-15mm。
进一步地，所述纸张为纤维素纸、铜版纸、成型纸中的一种，优选地，纸张的定量为40-100g/m 2。这几种纸张的烟气吸附能力较低，可降低烟气损失，提升抽吸体验，尤其适用于加热不燃烧卷烟。
进一步地，所述若干孔的总比表面积占纸张表面积的10％-50％，一般为15％-40％，优选为20％-35％。
进一步地，降温材料在纸张表面的涂覆面积占纸张表面积的50％-100％。可单面涂覆，也可双面均涂覆。
所述纸张的一面或两面涂覆有降温材料。
在本发明的一些实施例中，纸张表面具有涂覆有降温材料的涂覆区域和未涂覆降温材料的空白区域，所述空白区域和涂覆区域沿降温棒长度方向分布。
在本发明的一些实施例中，降温材料在纸张某一表面的涂覆区域分为至少两个，所述至少两个涂覆区域沿降温棒的长度方向分布。如此，各涂覆区域可相对独立地发挥降温作用，对烟气逐级降温，提升降温效果。进一步地，不同涂覆区域可涂覆不同类型的降温材料。
进一步地，所述降温材料为相变降温材料，优选为PEG(聚乙二醇)、聚葡萄糖、乳糖醇中的一种或几种。相变材料具有降温能力，烟气通过降温段时，与降温材料充分接触，可进一步提升降温效果。
进一步地，所述PEG包括PEG-200、PEG-400、PEG-600、PEG-800、PEG-1000、PEG-1500、PEG-2000、PEG-4000、PEG-6000、PEG-8000、PEG-10000、PEG-20000中的至少一种。
进一步地，所述降温材料包括低分子量PEG、中等分子量PEG和高分子量PEG中的至少两种。其中，所述低分子量PEG包括PEG-200、PEG-400、PEG-600、PEG-800中的一种或几种；所述中等分子量PEG包括PEG-1000、PEG-1500、PEG-2000、PEG-4000中的一种或几种；所述高分子量PEG包括PEG-6000、PEG-8000、PEG-10000、PEG-20000中的一种或几种。申请人反复试验后发现，.降温材料由低分子量PEG、中等分子量PEG和高分子量PEG中的两种或三种类型的PEG混合而成时，往往能获得较好的降温效果，且入口烟气量大，抽吸体验好；而单独选用某一种分子量类型的PEG时，往往无法获得理想的降温效果，而且入口烟气量较小，抽吸体验较差。优选地，按质量份计，降 温材料包括低分子量PEG0-10份、中等分子量PEG0-10份和高分子量PEG0-10份，其中，低分子量PEG、中等分子量PEG和高分子量PEG中最多有一者的含量为0。
进一步地，所述降温棒外包裹有成型纸。
进一步地，所述纸张展开时呈矩形，如此，可方便成型，也可保证成型后，降温棒长度方向各部分的通孔面积基本一致。
进一步地，所述降温段的一端或两端连接有过滤段，优选为醋纤滤棒，进一步优选为具有低烟气截留功能的特种醋纤滤棒。
进一步地，所述过滤段的长度为5-9mm，优选为6-8mm；降温段的长度为10-50mm，优选为16-35mm。
进一步地，降温嘴棒为圆棒，进一步地，周长为17-24.2mm。
本发明的降温嘴棒尤其适用于加热不燃烧卷烟。一般地，对于中心加热式加热不燃烧卷烟和包围式加热不燃烧卷烟，前三口的烟气温度较高，达到60℃甚至65℃以上，通过本发明的降温嘴棒可很好地满足其降温要求，使得入口温度降低至46℃左右，提升抽吸体验。
如上所述的降温嘴棒的制备方法，可先在纸张上涂覆降温材料，再将纸张送入成型机成型，获得降温棒，进一步加工获得降温嘴棒。
优选地，纸张的抗拉强度大于50N/m，以满足成型过程中受力要求。
进一步地，先将涂布有降温材料的纸张分切成4-20cm宽，对分切后的纸张首先进行预压纹路，纹路间隔宽度为1-10mm，纹路深度为0.1-1.0mm，再将压纹后的纸张送入成型机进行成型，形成降温棒，然后进一步加工获得降温嘴棒。进一步地，所述成型机可以为ZL-23成型机。
一种卷烟，包括发烟段和如上所述的降温嘴棒。进一步地，该卷烟为加热不燃烧卷烟。
进一步地，所述发烟段的长度为10-70mm，一般为10-50mm，优选为10-15mm，进一步优选为11-13mm。
进一步地，发烟段为经过处理的烟丝或薄片无序排列组成的烟条。
由于本发明的降温段具有耐高温的特点(300-320℃)，使得烟支设计时候，降温段能够与发烟段 直接相连，无需担心抽吸时降温段融化与烧毁情况发生，依然保持原形状，因而烟支设计可以简化为三段式结构；而现有iQOS烟支是四段式烟支结构设计，聚乳酸降温段的耐高温效果差(熔点155-185℃)，直接与发烟段相连接容易发生完全熔化现象，不能起到降温的效果，故在发烟段与降温段中间需设置耐高温的导流段，发烟段与导流段接触处的温度可以达到220℃左右。
本发明的降温嘴棒具有保证烟气烟雾量和降低进入口腔的烟气温度等优点，尤其是降温段，通过降温棒结构、降温材料种类与用量的组合设计，既可以让烟气易于快速流畅的由发烟段流出，又可以显著降低高温烟气在进入口腔之前的温度，烟雾量足且温度适宜，从而提升烟气抽吸的舒适感和满足感；还可解决现有加热不燃烧卷烟前三口抽吸时水汽过多、烟雾量小、口感不好的问题，而且具有明显的成本优势。
