ABSTRACT:
An environmental hood and duct structure for griddle and the like cooking equipment used in restaurant and similar facilities, for degreasing the air ambient to the cooking equipment, including a hood arrangement defining a water spray chamber having an air intake opening overlying the cooking surface of the cooking equipment involved, in which air intake opening is mounted an upwardly inclined grilling formed to define a plurality of individual grille openings shaped to provide a venturi effect on the air passing therethrough. The air is drawn across the cooking surface and into and through the grilling at a rate on the order of 1,000-3,000 cubic feet per minute, with the venturi affected air, on passing into the spraying chamber, being subjected to a cool water spray for wet scrubbing of the grease from the air. The scrubbed air is discharged to the atmosphere. The hood and duct structure includes a collection trough at the base of the grille for collecting the sprayed water and resulting solidified grease, and a make-up air duct opening adjacent the locale of the air inflow side of the hood grilling. The arrangement includes equipment for separating the grease from the water, and for recycling the water through the system.
