参见图9，以及参见图5、图6、图7、图8，作为一实施例，所述香烟制品100还包括桶状的限位管90，所述限位管90套在所述螺旋降温部件20上，所述限位管底面91与所述气雾产生载体10邻接，所述限位管底面91具有透 气孔洞92，所述限位管90位于所述外部包裹件50里面并受其限制，所述螺旋降温部件20与所述限位管90的内壁接触形成螺旋式通道，所述螺旋式通道的两端分别与所述气雾产生载体10和所述过滤嘴40相连通，以形成走气通道。作为一实施例，所述螺旋降温部件20为单螺旋杆，所述单螺旋杆的单螺旋槽70围绕所述单螺旋杆的杆轴80均匀设置，所述单螺旋杆的外径面与所述限位管90的内壁紧密接触以形成单螺旋式通道，所述单螺旋式通道的两端分别与所述气雾产生载体10和所述过滤嘴40相连通，以形成走气通道。作为一实施例，所述限位管底面91的透气孔洞92围绕限位管底面91的中心环绕设置，所述单螺旋杆邻接限位管底面91的一侧具有一凸台31，凸台31与限位管底面91的中心区域接触，优选地，凸台31与限位管底面91不含透气孔洞92的中心区域接触，目的是增加气雾的通过性。
所述限位管90的材质优选为硬质材质，这样起到对气雾产生载体10产生阻力支撑作用，气雾产生载体10在被电加热时(比如插入电加热探针时)，其里面包含的烟草或梗丝会向限位管90方向产生位移，邻接气雾产生载体10的限位管底面91可以将其支撑顶住，防止烟草或梗丝发生位移产生阻塞。
作为一实施例，所述气雾产生载体10包括再造梗丝，所述再造梗丝是烟草梗丝经过萃取降低或去除其中的可溶性蛋白、可溶性多糖、可溶性无机盐物质后，再向所述烟草梗丝回填预定致香物质而形成的再造梗丝。
作为一实施例，所述气雾产生载体10的再造梗丝被以在200-380摄氏度的温度范围内电加热从而产生气雾。
所述气雾产生载体10包括的再造梗丝，制备方法包括以下步骤：
步骤1：准备烟草梗丝，对所述烟草梗丝依次采用洗涤原梗、润梗、压梗、切丝、提取分离、烘干工序，去除或降低所述烟草梗丝中的蛋白、多糖、硝 酸盐物质，完成空白梗丝的制备；
步骤2：将烟草致香物质与气雾剂充分混合均匀获得混合物；
步骤3：将步骤1和步骤2制备的物料通过加料装置进行加料，并通过挤压挤压均化工序使物料充分均匀,进恒温恒湿工序进行水平衡后，打包备用。
所述气雾剂包括多元醇、多元醇的酯、聚合物、长碳链一元醇中的一种或几种组合。所述致香物质包括发性烟草精油、挥发性天然产物精油、烟草的分子蒸馏产物、挥发性食用香精中的一种或几种组合。
烟梗在烟草生长过程中因其特殊的功能—向叶片输送养分，促进烟草的成长，同时也壮大了自己。因其传输功能，其内部结构多孔多通道，故形成其特殊的结构和功效，这一特点是一般天然材料所不及的特质。
本发明就是充分利用烟梗材料的特殊结构和功效，特别是对烟梗进行提取加工后，不仅提升了其有效容纳物料空间，更避免了其受热后释放出的固有不良气息。
市场上看到的产品，烟雾基体材质所致，在加热过程中烤纸气息过重且烟雾量不足(用烟草薄片作为烟雾载体，因薄片制备由强度要求，故必须加入一定量的木质纤维，加热时产生烤纸气息，另外由于材质的限制，无法将气雾剂加的更多，最多在气雾基体内占比30％，故烟雾量受到限制)；
CN106723282A中描述过利用多孔烟草梗丝对雾化剂又很好地吸收能力，从而提高烟草制品的烟雾量，但没有考虑梗丝带来对烟草制品吸味的负面影响，也未涉及电加热不燃烧的情况。
一般加热不燃烧的烟草制品需要将烟草基材加热到200℃以上，产生含尼古丁的气溶胶。随着吸食者不断吸食，烟草基体不断被加热，被加热机体内含有的蛋白质、糖份随着温度的升高至焦化，发出令人不悦的焦糊气息。
本发明针对现有梗料适用于加热不燃烧时自身的不足，提供一种特制的再造梗丝，是将一般的烟草梗丝经过萃取降低或去除其中的蛋白、多糖、硝酸盐物质后，再向所述烟草梗丝回填预定致香物质而形成的再造梗丝。因为一般烟草梗丝中的蛋白、多糖、硝酸盐等物质，在电加热的这个温度范围内加热时，多糖及蛋白会产生焦糊气味，严重影响吸食者口感。另外，一般烟草梗丝中的硝酸盐受热分解产生亚硝酸盐(胺)，会对人体产生危害，也从根本上避免了部分硝酸盐热分解产生有毒气体的可能性。本发明所述气雾产生载体采用了特制的再造梗丝，可以很好地解决了一般烟草梗丝在电加热时的上述缺陷。
烟草梗料包括原梗料、梗丝料、颗粒梗料、梗粉末，无论是否膨化都在我们所述范围内。从加工和使用方便程度考虑，实施例中优选梗丝这种形态的梗料为例。
上述提取完成的梗丝与原梗丝的对比：
经过提取，梗料中90％以上的水溶物被剔除，其自身重量比原来减少一半。由于水溶物的剔除，不但增加了梗料吸收物料的空间，更主要的是将梗料固有的在高温时产生不良气息的化学组分剔除了，这是明显的优势；剔除的蛋白可以避免烟雾基体被加热时产生烧羽毛的气息；
经过提取，剔除绝大部分糖分也可以避免在加热时产生焦糊气息(包括多糖淀粉、果胶受热时产生的焦糊气息)；
经过提取，基本剔除了硝酸盐，极大程度地减少了硝酸盐受热分解产生亚硝酸盐(胺)的可能以及对吸烟者健康的危害；另外，也从根本上避免了部分硝酸盐热分解产生NO2有毒气体的可能性。
