ABSTRACT:
A moisture-collecting hood assembly (10) for a vapor-generating machine (12) includes a hood (14) having an open bottom (15)and upwardly tapering sides (16) and ends (18). On the inside of the hood is a gutter (24) for collecting moisture in the vapor condensing on the hood interior. Vapors from the machine that enter the hood are exhausted through a horizontally-oriented, moisture-collecting sleeve that has a central portion (46) whose cross-sectional area is larger than that of an inlet (43) in communication with the hood, and an outlet (48) in communication with a negatively pressurized exhaust line (49). The central portion of the sleeve serves to collect moisture in its lower portion that condenses from the vapor exhausted from the hood.
