阅读说明：本技术 一种异形烟草颗粒及其制备方法、烟草制品及其制备方法 (Special-shaped tobacco particles and preparation method thereof, tobacco product and preparation method thereof ) 是由 金勇� 陈潜 李克 喻赛波 范红梅 谭海风 王诗太 谭超 刘琦 于 2019-02-20 设计创作，主要内容包括：一种异形烟草颗粒,包括烟草颗粒本体和附着于烟草颗粒本体表面的包衣层,包衣层内含有胶黏剂,异形烟草颗粒的表面具有若干凹槽和/或凸条,和/或者,异形烟草颗粒内具有通孔。异形烟草颗粒的表面凹槽可作为烟草颗粒间粘结固化成型后的烟气通道,使全颗粒烟草制品内部透气性大幅提高,降低烟支吸阻,提高其燃烧性的同时使烟草原料使用量降低。此外还公开了该异形烟草颗粒的制备方法、包括该异形烟草颗粒的烟草制品及其制备方法。(The utility model provides a dysmorphism tobacco particles, includes tobacco particles body and attaches to the coating layer on tobacco particles body surface, contains the gluing agent in the coating layer, and the surface of dysmorphism tobacco particles has a plurality of recesses and/or sand grip, and/or, has the through-hole in the dysmorphism tobacco particles. The surface grooves of the special-shaped tobacco particles can be used as smoke channels formed by bonding, curing and molding the tobacco particles, so that the internal air permeability of the full-particle tobacco product is greatly improved, the smoking resistance of cigarettes is reduced, the combustibility of the cigarette is improved, and the usage amount of tobacco raw materials is reduced. In addition, a preparation method of the special-shaped tobacco particles, a tobacco product comprising the special-shaped tobacco particles and a preparation method of the special-shaped tobacco particles are also disclosed.)
