IPC: F24C15/32
Filed: 1997-07-11
Abstract: A modular cooking oven for cooking food products include a plurality of modules arranged in end-to-end relationship, with partitions between adjacent modules. A continuously moving conveyor belt (60) extends longitudinally through the oven from an inlet end to an outlet end. Hot cooking gas is continuously circulated in a closed path which is generally perpendicular to the longitudinal axis of the oven. The hot gas is circulated downwardly and then is directed through a plurality of axially spaced transversed slots (132, 134), both above and below the conveyor (60), toward the conveyor belt and food cooking therein. Spent gasses are then deflected away from the conveyor belt into a recirculation path, and are reheated prior to recirculation. Air and steam inlets are provided at various points, and are so arranged that an operator can provide either similar or different conditions of temperature and humidity in different modules. The oven interior may be cleaned by introducing a full strength cleaning solution through nozzles arranged at various points, and washing the cleaning solution down with water, while the oven is warm but not in use.
