Problems solved by technology

However, porous filter-type grease extractors tend to be relatively inefficient at extracting grease from contaminated air in an exhaust hood.
Hence, grease is typically carried into exhaust ducts and components of the exhaust hood, which reduces airflow over time and creates a potential fire hazard.
Secondly, the screens tend to clog, and they have to be removed and cleaned periodically.
The baffles creates a circuitous airflow paths that redirect and divert exhaust air that is being drawn into an exhaust hood which causes grease and

Abstract

A grease extractor is provided with a frame, a first array of convex baffle plates, a second array of concave baffle plates, and a steam ejector. The first array of convex baffle plates is carried by the frame in spaced-apart relation, so as to provide a first ventilation slot between adjacent, convex baffle plates. The second array of concave baffle plates is carried by the frame in spaced-apart relation, so as to provide a second ventilation slot between adjacent, concave baffle plates. A selected one of the concave baffle plates is offset from a respective, downstream convex baffle plate such that the first ventilation slot opens into a base portion of the concave baffle plate. The steam ejector is supported proximate each ventilation slot for delivering steam into the first ventilation slot and toward a respective one of the concave baffle plates. A method is also provided.

Description

RELATED PATENT DATA [0001] This application claims priority from U.S. Provisional Patent Application Ser. No. 60 / 637,264, which was filed Dec. 17, 2004, and which is incorporated by reference herein.TECHNICAL FIELD [0002] The present invention pertains to kitchen ventilation systems. More particularly, the present invention relates to grease extractors for kitchen ventilating systems, such as kitchen exhaust hood assemblies. BACKGROUND OF THE INVENTION [0003] It is previously known to use porous filter-type grease extractors supported within a frame to extract grease from contaminated air that is being drawn into a kitchen exhaust hood assembly. One such construction uses a metal mesh that is contained within an outer peripheral frame to provide a modular grease filter for an exhaust hood. However, porous filter-type grease extractors tend to be relatively inefficient at extracting grease from contaminated air in an exhaust hood. Hence, grease is typically carried into exhaust ducts...
