Description

一种加热不燃烧卷烟的测温系统及测温方法
本申请要求于2022年08月16日提交中国专利局、申请号为202210982266.5、发明名称为“一种加热不燃烧卷烟的测温系统及测温方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及烟草加工技术领域，更具体地说，尤其涉及一种加热不燃烧卷烟的测温系统及测温方法。
背景技术
“加热不燃烧”是新型烟草中比较火热的产品，它的原理是利用加热设备对烟草进行低温烘烤，而不发生燃烧。利用加热设备对特制的烟草进行加热烘烤，并将温度控制在低于燃点的范围内，这样既可以烘烤出烟草中的尼古丁以及各种芳香物质，又避免了由于燃烧所产生的有害物质。低温不燃烧设备拥有着与香烟最接近的口感和味道，又有着烟草独特的香气，同时也避免了绝大多数由于高温燃烧所产生的有毒有害物质，一经问世，就受到了广泛烟民的关注。
现有技术中的加热不燃烧卷烟往往是通过加热元件发热将热量传导给烟草物质，但是这种加热方式中靠近加热元件越近的烟草物质温度更高、加热速率更快，使得热量传递不均匀，这样也导致了加热不燃烧卷烟抽吸不均一，烟草物质易粘连加热元件的问题。因此，运用高频电磁波对烟草物质进行加热的技术应运而生，这种加热方式不存在加热元件，在物料内部发热，且几乎不需要传热过程即可很快达到高温，只要烟草物料内部介质均匀，就能实现整个物料体系的均匀加热，加热稳定性高。
但是由于高频电磁波在加热时会产生强磁场，现有技术中高频电磁波下的测温方式依旧是一个技术问题，传统的测温方式如热电偶，由于热电偶的测温探头是由金属材料制成的，所以在强电磁场下测温时，测温探头会产生感应电流，并在传感器的输入回路上产生压降，与有用信号叠加在一起，直接成为干扰信号，引起测量误差。
因此，亟需一种加热不燃烧卷烟的测温系统及测温方法，能够在强磁场环境下对加热不燃烧卷烟的加热温度进行测量，测量结果更加精确。
