ABSTRACT:
A method and apparatus for cooking foods such as donuts and pastries in hot oil with new steps and structure being provided to minimize airborne cooking oil and aeromatic odors. The method includes steps of directing an air sheet across the top of the cooking machines, collecting the air sheet and filtering oil several times to remove oil and odors, the collected air flow is split and a minority is recirculated as the air sheet and a majority is exhausted downward upon the floor. The apparatus is self-contained and has the cooking machine atop of a cabinet with the ventilation and filter system being inside the cabinet. There are first, second, third and fourth filters that remove the oil first and the odors lastly. A single air blower collects the air and oil and odors, causes flow through the filters, recirculates a minority portion of the air back to the machine, and exhausts a majority of the air to ambient.
