Description

一种发烟制品、发烟装置及其使用方法 技术领域
本发明涉及草本植物制品技术领域，尤其涉及一种发烟制品、发烟装置及其使用方法。
背景技术
传统卷烟是通过烟丝高温燃烧、裂解等化学反应后产生较多种类烟气产物进而被人们吸食，上述烟气产物不仅对吸烟者身体造成较大伤害，也对环境带来较多污染。因此，随着人们对健康的要求越来越高，出现了一种新型烟草，其通过对烟丝进行加热的方式来获取烟丝中尼古丁及香味物质以满足吸烟者的需求，该方式在一定程度上降低了身体伤害和环境污染。但尽管如此，烟草中所含的尼古丁等有害物质并不能完全去除，其仍然会影响着吸烟者的身体健康。
因此，本领域研发了一种新型的非烟草发烟制品，该非烟草植物主要采用茶叶和花果，通过对茶叶和花果进行预设温度的加热进而产生具有茶香、果香和花香的烟雾，以模拟和替代烟草的烟雾为人们带来抽吸快感。并且作为植物原料的茶叶和花果来源较广，品种繁多，采购方便，制备的发烟制品口味可根据茶叶和花果的种类进行灵活调整，以获得多种烟气口味，可满足多种人群的消费需要，该加热型茶烟制品具有非常广阔的市场前景。
目前，用于制备上述加热型茶烟的方法良莠不齐，茶烟结构多种多样。现有技术公开了一种茶烟制品，由茶叶发烟基质、具有通孔的冷却元件及滤嘴组成。上述冷却元件具有支撑阻挡作用、冷却烟气温度和允许烟气穿过进入滤嘴段的作用，上述冷却元件的材质一般为硅胶、塑料、纸板、醋酸纤维素或金属等；现常见的冷却元件为具有梅花状通孔的硅胶柱，主要作用是降低烟气温度。该硅胶柱的制备工艺相对复杂，在大量生产时增加了产品成本，并且硅胶材料不能降解，环保性较差，高温加热后会产生杂气，很难通过食品安全检测。同时对于发烟制品整体而言，其口感比较常规，茶香或香氛基本全由发烟制品一端的茶柱/烟柱产生，且随着抽吸时间的持续，其产生的茶香或花果香口感快速变淡，消费者不能获得较佳且持久的吸食体验。
发明内容
有鉴于此，本发明实施例提供了一种发烟制品、发烟装置及其使用方法，主要目的是解决发烟制品内的香味淡、吸食时间短、生产成本高以及材料不环保的技术问题。
为达到上述目的，本发明主要提供了如下技术方案：
一方面，本发明实施例提供了一种发烟制品，所述发烟制品包括：
第一发烟体、第二发烟体及过滤元件，并依次被外包装材料包裹于内形成一整体；
所述第一发烟体的上游端用于加热元件插入，所述第二发烟体的上游端邻接所述第一发烟体的下游端，所述过滤元件的上游端邻接所述第二发烟体的下游端，所述过滤元件的下游端用于吸食；
所述第一发烟体的原材料为烟草或非烟草，所述第一发烟体用于被所述加热元件加热后产生一次烟气；所述第二发烟体的原材料为烟草或非烟草，所述第二发烟体用于被所述一次烟气加热后产生二次烟气，所述第二发烟体具有供烟气通过的气体通道。
本发明实施例中的所述第一发烟体和所述第二发烟体为相邻设置，可互相抵接，也可稍有间隙，上述三个部件按前后顺序以首尾相接的方式被包裹在外包装材料内；所述加热元件为本领域常见设备，形状为销状或刀片状，其长度一般为固定长度，其插入第一发烟体的深度有限，产烟量有限。本发明实施例设置第二发烟体解决了上述问题，其不需要加热元件来加热，而是充分利用第一发烟体的余热来加热，进而继续产生烟草香味、茶香味或花果香；在加热元件插入到所述第一发烟体时，所述第二发烟体对所述第一发烟体也具有支撑作用。
本发明实施例的所述加热元件正常工作时温度在100℃-500℃左右(大部分在200℃-300℃)，所述第一发烟体中越靠近加热元件的部位，其温度较高；相反，远离加热元件的部位温度较低；产生的一次烟气的温度大约在50-150℃左右，该温度足以加热所述第二发烟体以产生二次烟气；所述二次烟气的温度大约在50-100℃左右，所述二次烟气借助吸食者的抽吸力进入所述过滤元件后，再次降温至大约30-50℃左右被吸食。
本发明实施例的发烟制品中的第二发烟体结构中具有可供气体通过通道。例如，在其结构内设置空隙、孔隙或通孔等允许气体通过的结构，所述气体通道的大小影响第一烟气的通过速度，该速度影响第一烟气加热第二发烟体的快慢或充分性，进一步影响降温效果和吸阻，也决定着第二发烟体原材料和香精的使用量，进而影响第二发烟体的烟雾量和增香效果。因此，所述第二发烟体的内部结构(即透气度或疏松程度)不能过于疏松或过于紧实。所述第二发烟体结构中的气体通道的数量、排列、形状等均可以根据实际需要设计，只要符合烟支或茶烟支常规通气量或透气度或吸阻即可，且需考虑到消费者的抽吸舒适度和生产成本等。
本发明实施例的第一发烟体作为主要发烟源，其结构相对较为紧密，使用原料多，可产生较多烟雾量和浓郁的香味；第二发烟体作为次要发烟源，结构疏松，使用原料少，烟雾量较小，香味较淡，所述第二发烟体作为继续发烟源，其最主要功能是增补香味或香气，同时吸收一次烟气热量，冷却一次烟气温度，且产生二次烟气，起到冷却烟气的作用(充分利用一次烟气的热量和二次烟气的降温需求)，由于所述第二发烟体结构相对疏松，具有适中密 度或透气度，其作为气体通道将烟气输送至过滤元件。
本领域常规发烟制品在第一发烟体的下游端设置硅胶柱冷却元件，其是为烟气穿过提供气体通道和利用硅胶材料特性进行冷热交换以达到降低烟气温度目的，该技术方案中发烟体挥发出的具有较高温度的烟气含有较多热量，该热量是需要被消除的，同时硅胶柱降温也产生了硅胶材料的消耗，且硅胶不能自然降解，硅胶受热会产生杂气，产品质量检测会含有害气体，硅胶材料无法回收，污染环境；即在本领域常规技术方案中，在发烟体与过滤嘴之间的烟气所带来的热量是需要被消除的，为了消除该热量也需要消耗硅胶等具有相似功能的材料。
本发明人发现上述常规技术方案中在上述热量传递阶段存在着资源浪费，如果能充分利用该需要消除的热量，又能有助于抽吸品质，增加口感体验，则将是本领域一具有显著进步性的技术。因此，本发明人为了解决上述技术问题，经过多次研究、反复实验和口感品质的数百次验证，发现在所述第一发烟体的下游端再接一段发烟体，即所述第二发烟体，其原材料可以根据口感需求选择各种茶叶和花果，也可以在其中涂敷或浸渍香精或香料；同时，所述第二发烟体的结构须疏松，即透气度需大于或等于第一烟气生基质的透气度，所述发烟制品的两段需具有合适的吸阻，该结构设计成较为疏松的特点，可使大量烟气通过，可充分利用第一烟气带入的热量加热第二发烟体，使其内的可挥发物质尽可能多的挥发出来，不浪费冷却元件的原材料和第一发烟体的热量。该设计将必须消除的热量、需要具有冷却与通气功能的结构设计、第二次香味的生成与传递和环保要求相结合，充分利用该创新结构，解决了上述技术问题，也达到多方面的有益效果。
作为优选，所述第一发烟体和所述第二发烟体均为非烟草，所述非烟草包括茶叶。

在上述描述中，两者选用的茶叶品种可以相同，例如，均为红茶，也可以不同，例如，一个是红茶，另一个是绿茶和/或花果茶，具体选择可根据实际口感的需要来设定。
作为优选，所述第一发烟体和/或所述第二发烟体含有香料或香精。
作为优选，所述香料或香精选自草莓提取物、香蕉提取物、西瓜提取物、水蜜桃提取物、蓝莓提取物、菠萝提取物、芒果提取物、丁香提取物、沉香提取物、哈密瓜提取物、苹果提取物、柑桔提取物、咖啡及薄荷醇中的至少一种。
在上述描述中，所述第一发烟体和所述第二发烟体中的香精或香料的种类不同；所述第一发烟体的香精或香料的含量大于所述第二发烟体中的香精或香料的含量。当两者均添加香 氛材料时，各自所添加的香氛材料种类不同，数量不同，含量不同，该设计是为了在发烟制品被抽吸时，使其中的茶香味、花果味、香氛气味随时间变化会产生渐变的且有层次感的效果；两段的茶叶品种的选择和两段的香氛材料的选择可以根据一次烟气和二次烟气具有的热量与茶香和香氛的协同关系进行选择，充分利用两段不同大小的热量可挥发出不同量的茶香或香氛，以达到茶香或香气的口感(如口味浓郁或口味清淡)随抽吸时间的变化而产生具有层次感的渐变效果。
本发明实施例中，主要是对发烟制品的结构进行了改进，重点是对中间段，即第二发烟体的结构和材料进行了创新。发烟制品的调香或配香技术为本领域常规技术。
作为优选，所述第一发烟体的密度为0.2-1.2g/cm 3，所述第二发烟体的密度为0.1-1.0g/cm 3；在实际生产中，大部分情况下，第一发烟体的密度大于等于第二发烟体的密度，否则吸阻太大，不适宜抽吸。

本发明实施例中，透气度(或透气量)指物体或介质允许气体通过的程度，可以通过测量单位体积或截面在单位时间和特定压力下透气量的大小而获得数值；在规定的压差条件下，测定一定时间内垂直通过试样给定面积的气流流量，计算出透气量。所述透气度的测试原理是在规定的压差条件下，测定一定时间内垂直通过试样给定面积的气流流量，计算出透气量；气流速率可直接测出，也可通过测定流量孔径两面的压差换算而得。本发明实施例的第一发烟体的透气度或透气量小于第二发烟体的透气度或透气量；所述第一发烟体的密度较大，透风率或透气度或透气量较小，所述第二发烟体的密度相对较小，相应的透气量相对较大。上述密度或透气度或透气量可根据实际需要在卷制过程中对第一和第二发烟体的疏松度进行相应调节，上述疏松度与发烟制品的直径、基片的厚度、卷制的宽度等相关，通过综合调节两段的疏松度来获得吸阻小、香气浓和烟量大的综合效果。
本发明上述实施例中，发烟体的原材料为茶叶，茶叶本身具有一定孔隙，烟气可从多个 孔隙中穿出，这种方式取决于原材料的透气度，其为次要气体通道；本发明实施例的所述气体通道主要是指通过所述第二发烟体的卷制结构形成，其为可供烟气从第二发烟体一端进入并从其相对的另一端穿出的通道，该结构设计可使大量烟气通过，结构疏松，抽吸阻力小，换热效果好。
作为优选，所述第一发烟体是由灌浆凝固形成或由颗粒灌注形成或由整张纯基片从其一端卷至另一端以呈现外层卷裹内层的方式形成或由整张丝网基片从其一端卷至另一端以呈现外层卷裹内层的方式形成或由多根互相独立且不相连的丝条卷制成束状的方式形成，记为A特征；和/或，
所述第二发烟体是由整张纯基片从其一端卷至另一端以呈现外层卷裹内层的方式形成或由整张丝网基片从其一端卷至另一端以呈现外层卷裹内层的方式形成或由多根互相独立且不相连的丝条卷制成束状的方式形成，记为B特征；
其中，所述丝网基片是将所述整张基片制成多根同向丝条，且两两相邻的所述丝条之间至少设有一个相接点，以将所述多根同向丝条连接形成网片状；所述丝条与丝条之间的间隙形成所述气体通道或所述外层与所述内层之间的间隙形成所述气体通道(该技术方案是用于描述第一发烟体和第二发烟的丝网基片和气体通道)。
上述描述方式中，“和/或”的意思表示在发烟制品中，第一发烟体具有A技术特征，或者，第二发烟体具有B特征，或者第一发烟体具有A特征的同时第二发烟体具有B特征。
在上述实施例中，第一发烟体在卷制时需考虑其应具有合适插入阻力和适宜吸阻的情况下，将其卷制成外层紧紧包裹内层的卷绕结构；第二发烟体在卷制时需考虑到合适的吸阻和尽可能调节原材料的量以控制产香与产烟量的情况下，将其卷制成外层疏松包裹内层的卷绕结构，所述紧紧包裹与所述疏松包裹为卷绕结构的相对情况，具体密度可根据实际需求设定。
作为优选，所述发烟制品的直径为0.68-0.72mm时，所述第一发烟体的整张纯基片或所述整张丝网基片的厚度为160-200g/m 2，进一步优选170-190g/m 2，进一步优选175-185g/m 2，最佳为180g/m 2；预设卷制直径为7mm时，卷制宽度为100-130mm，进一步优选105-125mm，进一步优选105-120mm，进一步优选105-115mm，进一步优选105-110mm，最佳为110mm，此时第一发烟体的密度较佳，可同时满足插入摩擦力适中和吸阻小的要求。

本发明上述实施例中，所述第二发烟体的密度越大，其吸阻越大，烟雾量越小，产香越浓。在固定第二发烟体外径的前提下，基片的卷制宽度影响卷制后发烟体的密度，宽度越大，卷制的圈数多，密度大；宽度越小，卷制的圈数少，密度小；基片的厚度也影响卷制后的发烟体的密度，基片越厚，卷制的发烟体的密度越大；基片薄，卷制的发烟体密度小；考虑到产品效果和成本等综合因素，在加工生产时需要调整基片具有适宜的卷制宽度和厚度，使两段发烟体具有较佳的密度和透气度，产生适宜的烟雾量和香气，即以最大浓度产香的同时使吸阻较小。
作为优选，所述过滤元件包括一段式结构、两段式结构或三段式结构；所述一段式结构包括实心柱体、空心柱体或中空柱体；所述两段式结构包括中空柱体、实心柱体及空心柱体中任意两种结构的组合；所述三段式结构包括中空柱体、实心柱体及空心柱体中的至少两种结构按三段式组合而成；所述第二发烟体与所述过滤元件之间设置爆珠和/或所述过滤元件的实心柱体内嵌设爆珠，所述爆珠内含有香料或香精；所述中空柱体的中空处的横截面的形状包括圆形、椭圆形、正方形、正六边形、心形、五角星形或圆环形。以上材料为市购或从厂家定制。

本发明制备发烟制品时，第一基片克重160-200g/m 2，卷制宽度为50-230mm，对应密度为0.2-1.2g/cm 3；第二基片克重100-140g/m 2，卷制宽度为40-270mm，对应密度为0.1-1.0g/cm 3。
当固定第一基片克重为180g/m 2，第一发烟体卷制宽度为50mm，对应密度为0.24±0.05g/cm 3，第一发烟体卷制宽度为230mm，对应密度为1.08±0.05g/cm 3；当固定第二基片克重为120g/m 2，第二发烟体卷制宽度为40mm，对应密度为0.12±0.05g/cm 3，第二发烟体卷制宽度为270mm，对应密度为0.84±0.05g/cm 3。
当固定第一基片克重为160g/m 2，第一发烟体卷制宽度为50mm，对应密度为0.20±0.05g/cm 3，第一基片克重为200g/m 2，第一发烟体卷制宽度为230mm，对应密度为1.2±0.05g/cm 3；当固定第二基片克重为100g/m 2，第二发烟体卷制宽度为40mm，对应密度为0.1±0.05g/cm 3，第二基片克重为140g/m 2，第二发烟体卷制宽度为270mm，对应密度为1.0±0.05g/cm 3；
以上实际测量数据均有较小误差，本发明实施例采用上述数据范围制备的发烟制品，当密度太大时，产品吸阻较大，香味很浓，但烟雾量较少；当密度太小时，吸阻小，烟雾较多，但香味稀淡；采用以上偏大或偏小的宽度/克重制备的发烟制品的综合品质大概评为3-4(差良)至4-5(良)，采用上述各尺寸制备的发烟产品可抽吸，制作工艺上也可实现，但抽吸 感较差。
其他数据段的实验为实施例1-实施例37，表1为实施例1-实施例37制备的发烟制品的密度测量数据，实际测量数据与理论计算数据的误差在±0.05左右，其均在本技术领域可接受范围内。本发明仅以表1中列举的较为适宜的宽度和克重来制备本发明的发烟制品，以证明其综合品质至少在优秀以上，工厂批量生产(可手工或机器)可从表1中择优而用。
由表1密度数据可知，在卷制直径(7mm)、基片克重(180/120g/cm 2)不变的情况下，随着第一发烟体/第二发烟体卷制宽度的增大，第一发烟体/第二发烟体的密度随之增大，在不同卷制宽度下测量的密度数据有交叉现象，其误差可接受。
通过对比表1实施例1-37的密度和与之对应的表2的评吸结果，可知实施例15-实施例18的发烟制品的综合特性相对较优，其中实施例17效果最优；在以上直径、基片克重相同的情况，通过改变第一发烟体或第二发烟体的卷制宽度，可调节其密度，其各自密度和两者密度的组合直接影响发烟制品综合品质；由表2可知，当第一发烟体卷制宽度为110mm，第二发烟体卷制宽度为80-95mm，上述发烟制品整体的综合品质较优，当第二发烟体卷制宽度为90mm左右时上述发烟制品整体的综合品质最优；相应的，发烟制品综合品质为优，第一发烟体的密度为0.40-0.80g/cm 3，第二发烟体的密度为0.20-0.50g/cm 3；较优的，第一发烟体的密度为0.40-0.60g/cm 3，第二发烟体的密度为0.2-0.40g/cm 3；最优的，第一发烟体的密度为0.50-0.60g/cm 3，第二发烟体的密度为0.25-0.35g/cm 3，以上密度范围均需考虑实际误差。
上述35个实施例的第一发烟体和第二发烟体的基片均为表面平整的纯基片(不切丝)，上述实施例36、实施例38、实施例39以及实施例40的第一发烟体和第二发烟体的基片均为丝网基片(压丝且不完全中断)，上述实施例37的第一发烟体和第二发烟体采用各自独立的丝条卷制(切丝且完全中断)。
表2为实施例1-实施例40发烟制品的各种特性的评吸调查结果，通过对比实施例的各特性，可知实施例17、实施例36-实施例40的香味浓郁、余味浓、烟雾持续时间长、无杂气、无刺激性、不烫嘴、插入力适中、吸阻适宜，其综合特性评为最优；实施例15、实施例16、实施例18的综合品质与实施例17相比，其香味和烟雾效果次之，三者的综合品质评为较优；其余实施例的发烟制品综合品质次优，评为优，实施例1-40制备的发烟制品的综合特性在优以上，其均可达到本发明的技术效果。
表2中，对比实施例17和实施例36，两者卷制基片结构不同，实施例36采用丝网基片卷制的发烟体的透气均匀性(密度均匀性或孔隙均匀性)比实施例17采用完整基片卷制的发烟体的透气均匀性要好，实施例36的吸阻较小，且该感官较为明显，说明在其他条件不 变的情况下，采用丝网基片卷制的效果比完整基片卷制的效果要好。
表2中，对比实施例36和实施例37，综合品质基本差不多，但由于实施例37是将完整基片先切成各自独立的丝条后再用包装纸卷裹为一体，因其是将各丝条卷制在一起，其透气性和吸阻性相对较好，在密度达到不会使丝条散落且又符合吸食要求的情况下，采用该技术制备的发烟制品综合品质较好，但该技术也具有一定弊端，即其对发烟体的卷制密度有一定限定，不能过于疏松，否则丝条容易散落，其密度不能灵活调整，因此，本领域技术人员可根据实际需要灵活选用。
表2中，实施例38-实施例40，其结构与实施例36完全相同，仅茶叶类型不同或添加的香精香料不同，其各品质效果与实施例36基本相似，说明采用实施例36的丝网卷制结构，当改变发烟体配方中茶叶或香味类型时，所达到综合品质较为稳定，本领域技术人员可根据实际需要对发烟体的配方进行相应调整，且调香技术为本领域的现有技术。
表3为实施例36、对比例1和对比例2抽吸烟雾检测数据表，实施例36代表本发明发烟制品的创新结构(第一发烟与过滤元件之间设置第二发烟体，其材料为非烟草，具体为茶叶)，对比例1和对比例2为市售发烟制品的传统结构(第一发烟体与过滤元件之间设置冷却元件，例如可通气的硅胶柱或可通气的卷制的聚乳酸柱体)，对比例3因其在第一发烟体与过滤元件之间未设置任何结构，仅由外包装材料卷制时形成一空筒，其烫嘴情况较为严重，不考虑其综合品质。
通过表1的评吸结果可知，对比例1和对比例2皆有稍微烫嘴的感觉，其吸阻相对较大，香味较淡，烟雾持续性较差，其原因在于对比例1中间段采用带通孔的硅胶柱冷却和传递烟气，硅胶材料吸热冷却效果差，待烟气穿过过滤元件进入口中时会有稍微烫嘴的感觉，由于第一发烟体出来的烟气温度大概有一百多摄氏度再进入硅胶柱里，硅胶受热会产生硅胶杂味，该味道会影响发烟制品的整体香味，即香味中参杂着硅胶柱的杂气，该产品如若控制不好，不易通过产品质量检测；并且该发烟制品中仅有第一发烟体为烟草或非烟草材料，其受热挥发出的香味和烟雾有限，且更重要的是吸食完后该发烟体会被废弃，导致硅胶成为一次性消费材料，废弃时更会污染环境；综上，采用硅胶柱作为冷却元件会产生烫嘴和污染环境、香味淡、烟雾持续性短以及成本高的问题，该缺陷也是含硅胶发烟制品一直以来未能很好解决的技术问题。对比例2采用聚乳酸基片卷制发烟体，其材料虽环保，但也是一次性使用，产烟段仍只有第一发烟体，其香味较淡，烟雾持续时间较短，聚乳酸材料成本也较高。
由表3的对比结果可知，以实施例36为代表的本发明的发烟制品和以对比例1和2为代表的发烟制品从第1口至第10口的气溶胶(可代表烟雾量)先上升到最高点再降低，但 本发明的发烟制品气溶胶浓度整体偏高，且下降速度平缓，相对的对比例1和2的发烟制品的气溶胶浓度整体偏低，且下降速度急促，以第10口为例，本发明检测为2.86，对比例1盒2分别检测为1.96和1.66，将其等同于抽吸口数，本发明大概比对比例1和2多出2-5口左右，其原因主要在于本发明第一发烟体先受热挥发出一次烟气，该一次烟气继续加热第二发烟体，继续产生二次烟气，故本发明发烟制品整体不仅增加了烟雾量，还延长了产烟时间，起到增香补香的效果，且口数相对增多，吸食者体验感较佳。
本发明的主要创新技术是将茶叶原料卷制成一柱状物体，以替代传统发烟制品内部的冷却元件(例如硅胶柱)，达到冷却烟气、输送烟气、增香补香、提高综合口感、环境友好、合理利用资源以及降低生产成本的技术效果。本发明技术方案中对第二发烟体卷制的松紧程度不作定性要求，只要可使挥发出的烟气通过即可，并且消费者在吸食时的吸阻可接受，抽吸体验相对舒适即可。
通过上述各实施例和对比例的茶烟的多方面评吸，证明本发明实施例的茶烟结构所带来的综合口感更胜一筹，更受消费者喜爱。本发明实施例的上述茶烟制品的结构突破了传统思想，未沿用行业里一直以来对硅胶柱结构设法改进的技术思路，创新性的发现以茶叶材料作为中间段结构仍然可以达到冷却烟气和输送烟气的效果，并且当采用茶叶材料作为冷却和输送烟气结构时，该茶叶材料可以继续产烟，增加茶香的可持续吸食性，同时，也恰当好处的利用常规茶烟制品一直想办法要消除的第一发烟体带来的热量，本发明的上述结构设计不仅改进了发烟制品的口感等综合体验，还做到了物尽其用，避免浪费热量和本领域为配合消除热量而设计的冷却元件所采用的硅胶等材料，节省了原材料，降低了生产成本，由于口感的提升，更受消费者欢迎，为企业提高了盈利。
本发明实施例中未尽之处，本领域技术人员均可从现有技术中选用。
以上公开的仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以上述权利要求的保护范围为准。
