ABSTRACT A ventless hood for a commercial deep fat frying pressure cooker having a pot in which cooking is performed by the use of a heated cooking oil bath and steam under pressure derived from the moisture in the food being cooked. The hood comprises a vertical portion at the rear of the cooker and a forwardly extending open-bottom portion spaced from and overlying the pot. The forwardly extending portion of the hood supports a pair of angularly related baffle filters surmounted by a metallic mesh filter and a charcoal filter. A fan in the vertical portion of the hood draws ambient air and cooking gasses through these filters. A water tank is mounted behind the cooker together with a pump to recirculate the water in the tank through a heat exchanging radiator located between the filters and the fan to cool the water. During the cooking cycle excess steam and vaporized cooking oil are introduced into the water bath which acts as a scrubber and condenses the majority of the steam and vaporized cooking oil. Residual non-condensables, uncondensed steam, vaporized cooking oil and unabsorbed odors are vented from the water tank directly to the bottom of the forward hood portion. At the end of the cooking cycle all of the cooking gasses are vented into the water bath prior to opening of the cooking pot.
