The pressure fryer is a stand alone commercial unit by Broaster used for frying chicken. Check out broaster.com. The pressure smoker is used for cooking BBQ pork or beef(smokearoma.com). Both units are waterless except for the moisture in the product. Altitude for my application is sea level.
How are pressure cookers treated under commercial kitchen hoods? Both pressure fryers and pressure smokers are closed during the cooking cycle and only opened after cooking is complete. This must make for a reduced grease vapor and heat production.
