Description
Technical Field
The invention relates to the field of production of conventional cigarettes and heating non-combustion tobacco products, in particular to a glycerol adding process in a shredding process.
Background
In recent years, heating non-burning cigarettes has received great attention from consumers in foreign markets. As a low-temperature cigarette, aerosol is formed mainly by a relatively temperature controllable heating mode such as electric heating or carbon heating for smoking. While maintaining a large amount of aerosol formation at low temperatures, adding a smoke agent while reducing moisture is currently the most dominant control. At present, the main smoking agent for heating the non-combustion cigarette is glycerin, and the addition of the glycerin can obviously promote the nicotine in the tobacco and the product to realize effective release at a lower temperature. At present, tobacco sheets are mainly used as raw materials for the cigarette which is not combusted by heating, and glycerol is mainly added by a coating method, but with the development of the cigarette which is not combusted by heating, the cigarette which is not combusted by heating and is prepared by adding non-sheets such as cut tobacco and the like also begins to be produced. Therefore, how to realize the effective addition of the glycerol in the silk making process becomes more urgent.
In the traditional cigarette preparation process, polyalcohol substances such as glycerin and the like are usually used as humectants, the addition amount of the polyalcohol substances is low, and the polyalcohol substances are mainly added in a blending formula mode in the processes of feeding and perfuming. However, in the case of heating non-burning cigarettes, the addition amount of glycerin as a main smoke agent is large, and the loss in the drying process is large due to the excessive addition amount in the previous process, so that the utilization rate is low and the economical efficiency is poor. However, if the tobacco shreds are added in the subsequent flavoring process, the tobacco shreds are too dry and have low moisture content, so that the tobacco shreds are difficult to absorb a large amount of the tobacco shreds quickly, the adding efficiency is low, and the tobacco shreds are easy to adhere to equipment. Meanwhile, compared with the traditional cigarette, the cigarette which is not burnt by heating has lower requirement on the moisture content, and the phenomenon that the crushing amount is obviously increased in the process is difficult to avoid.
