<p>The system foresees the production of heat and smoke in combustion chamber (1), by means of burner (2), which pass through a collector (3) communicating with a heat exchanger (4) such that heat is exchanged by induction to air drawn from outside by an air intake (5). The heated air flows from air intake (5) via pipe (6) into chamber (7) centrally including the combustion chamber (1). In this way said forced flow is overheated by contact with the walls of the combustion chamber (1) to the required temperature. The heated air flows via pipe (8) into roasting chamber (9) where it passes over the product when moving into roasting unit (10). Said hot air flow crosses the product so as to heat it to the required temperature and then the hot air is discharged with the roasting smoke in suspension, through pipe (11). The hot air is then sucked by an intake group (12) producing the forced circulation. Said gaseous flow comes finally to a cyclone separator (13) having the function to remove the bigger dimension particles from the air. The air/smoke suspension then passes to the atmosphere through an after burner (14). Where it is heated to a temperature (400 DEG -700 DEG ) such that it ignites. <IMAGE></p> |
