Abstract
Abnormally-shaped tobacco granules are provided. The tobacco granules comprise a tobacco granule body and a coating attached to the surface of the tobacco granule body. The coating contains an adhesive. The surface of the abnormally-shaped tobacco granule has one or more grooves and/or ridges, and/or, the abnormally-shaped tobacco granule has through holes therein. The surface grooves of the abnormally-shaped tobacco granules can serve as smoke channels after the tobacco granules are bonded, cured and shaped, so that the air permeability inside a total-granule tobacco product is greatly improved. The smoking resistance of cigarettes is reduced. The flammability of cigarettes is improved and the consumption of tobacco raw materials is reduced. A preparation method of the abnormally-shaped tobacco granules, a tobacco product comprising the abnormally-shaped tobacco granules, and a preparation method thereof are also provided.
