技术领域Technical field
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***及测温方法。The present application relates to the field of tobacco processing technology, and more specifically, to a temperature measurement system and temperature measurement method for heat-not-burn cigarettes.
背景技术Background technique
“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。"Heat-not-burn" is a relatively popular product among new tobacco products. Its principle is to use heating equipment to bake tobacco at low temperature without burning. Heating equipment is used to heat and bake special tobacco, and the temperature is controlled below the ignition point. This can not only bake out the nicotine and various aromatic substances in the tobacco, but also avoid harmful substances produced by combustion. . Low-temperature non-burning equipment has the closest texture and taste to cigarettes, and has the unique aroma of tobacco. At the same time, it also avoids most of the toxic and harmful substances produced by high-temperature combustion. Once it came out, it has attracted the attention of a wide range of smokers. .
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。Heat-not-burn cigarettes in the prior art often conduct heat to the tobacco material through the heating element. However, in this heating method, the tobacco material closer to the heating element has a higher temperature and a faster heating rate, resulting in uneven heat transfer. , This also leads to the problem of uneven smoking of heat-not-burn cigarettes, and tobacco substances easily stick to the heating elements. Therefore, the technology of using high-frequency electromagnetic waves to heat tobacco materials came into being. This heating method does not have heating elements and generates heat inside the materials. It can reach high temperatures very quickly without any heat transfer process. As long as the medium inside the tobacco materials is Uniform, uniform heating of the entire material system can be achieved, and the heating stability is high.
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。However, because high-frequency electromagnetic waves will generate strong magnetic fields when heated, the temperature measurement method under high-frequency electromagnetic waves is still a technical problem in the existing technology. Traditional temperature measurement methods such as thermocouples, because the temperature measurement probe of the thermocouple is made of metal materials. Therefore, when measuring temperature under a strong electromagnetic field, the temperature measurement probe will generate an induced current and produce a voltage drop on the input loop of the sensor, which will be superimposed with the useful signal and directly become an interference signal, causing measurement errors.
因此，亟需一种加热不燃烧卷烟的测温***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。 Therefore, there is an urgent need for a temperature measurement system and temperature measurement method for heat-not-burn cigarettes, which can measure the heating temperature of heat-not-burn cigarettes in a strong magnetic field environment, and the measurement results are more accurate.
