Machine for drying shredded snuff in particular for rolls of expanded shredded snuff.

摘要

The machine (1) includes a structure (2) tunnel defining a chamber (8) with longitudinal side walls (9) inclined downwardly converging, and in which a substantially horizontal conveyor (10) for conveying a flow layers crumbled (T) from the inlet end (6) to the outlet end (7) of the chamber (8), snuff extends adjacent the lower edges (9b) of the side walls (9) converging. a ventilation system (16-25) provided in the latter, with a distribution manifold (16) extending above the conveyor (10), a cluster of vertical tubes (17) extending from the manifold (16) to a predetermined distance from the conveyor (10), between the lower edges (9a) of the side walls (9) converging a return manifold (18) communicating with lateral regions of the chamber (8) located on the sides of the group of tubes (17) and above the side walls (9) converging, and an apparatus (20-25) of air conditioning and recycling, interposed between the outlet (23) of the return manifold (18) and the distribution manifold (16), to induce a flow of conditioned air through the tubes (17) towards the conveyor (10), so that the air leaving the tubes (17) creates a bed of air above the conveyor (10) for fluidizing the layered flow of snuff (T).
