    摘要： A flame proof grease extraction system for removing grease, oil and other condensable contaminants from a vaporous exhaust stream in a kitchen ventilating system. The grease extraction system comprises a housing with an entranceway for receiving the exhaust stream, an outlet for discharging the exhaust stream into a duct which contains a blower or fan for drawing the exhaust stream through the extraction system, and internal baffle means for guiding the exhaust stream along a predetermined path designed to provide the extracting action. The baffle arrangement includes an entrance baffle which extends rearwardly from the top of the entranceway for deflecting the entering exhaust stream rearwardly over the bottom wall of the extractor housing. A second baffle means then defects the exhaust stream upwardly from the bottom wall around the rearward edge of the entrance baffle means and forwardly over the top of the entrance baffle means toward the front wall. Third baffle means then defects the exhaust stream rearwardly from the front wall and down along the rear side of the second baffle means to the bottom wall, and then upwardly again between the rear side of the third baffle means and the rear wall of the housing. A drain means is provided in the bottom wall of the housing for receiving the extracted grease and oil which is deposited on the internal surfaces of the system, and which runs downwardly thereover due to the heating of the internal surfaces by the adjacent cooking surface.
