Tobacco cake subdividing apparatus for use in cut tobacco expanding system

Abstract

A fine cutting device for an expanding system comprises a primary declamper for receiving an impregnated cut tobacco cake taken out from an impregnator and fine cutting the received tobacco cake into tobacco loaves and a secondary declamper for receiving the tobacco loaves from the primary declamper, fine cutting the tobacco loaves into tobacco chunks and then cutting more fine the tobacco chunks into tobacco lumps. The secondary declamper comprises a pair of rotary rakes, and a rotary drum rake (26) disposed under the rotary rake.

Description

technical field [0001] The invention relates to a subdividing device used in a shredded tobacco puffing treatment system. The subdividing device subdivides cigarette agglomerates formed by solidifying impregnated shredded tobacco before air-drying shredded tobacco impregnated with liquid carbon dioxide. Background technique [0002] The puffed shredded tobacco used as one of the filling materials of the cigarette improves the filling efficiency of the filling material in the cigarette. Expanded cut tobacco is produced by a expanding processing system having an impregnation vessel. The shredded tobacco is supplied into an impregnation vessel in which the shredded tobacco is impregnated in liquid carbon dioxide. Thereafter, the impregnated shredded tobacco was taken out from the impregnator, and supplied to a blow dryer. The air dryer rapidly dries the impregnated shredded tobacco, through which solid carbon dioxide in the impregnated shredded tobacco is vaporized, and carbo...

AI Technical Summary

Problems solved by technology

However, the rotating rake type subdividing device cannot completely subdivide the cigarette agglomeration into cigarette lumps (tobacco lumps) below the desired size, leaving a large amount of large pieces (largemasses) with a size above the small cigarette lumps, that is, cigarette lumps (tobacco lumps). tobacco loaves); and medium masses (tobacco chunks)

If the large pieces of cigarettes or the middle pieces of cigarettes are supplied to the airflow dryer in this way, the impregnated cut tobacco in the large pieces of cigarettes and the middle pieces of cigarettes cannot be dried uniformly, and the quality of puffed shredded tobacco will be reduced.
