Abstract:

The coating process is one of the core technologies forin the manufacture of reconstituted tobacco. In the investigation, three rheological additives, namely CMC, GG-50 and CGG, were respectively added into the coating to adjust the coating properties and improve the coating process. Then, the relationship between the additives and the properties of the reconstituted tobacco after coating is discussed. The results show that (1) with the increase of the rheological additive dosage, the coating viscosity and the tensile strength and the tear index of the reconstituted tobacco after coating increase while the bulk, the air permeability and the filling value of the reconstituted tobacco after coating decrease; (2), simultaneously, the release amounts of tar, total particulate matter and carbon monoxide in the main smoke also rise. The SEM analysis of reconstituted tobacco shows that when all the dosages of the three rheological additives are all 0.1%, the coating structure on the reconstituted tobacco surface is better, , the coating fills in the inside of reconstituted tobacco base-paper, and there is no fragment on the coating surface.
