  • Patent number: 5826496
    Abstract: The invention relates to a cooking oven for cooking food products. A modular cooking oven herein disclosed may include a plurality of modules arranged in end-to-end relationship, with partitions between adjacent modules. A continuously moving conveyor belt 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. A hot gas is circulated downwardly and then is directed through a plurality of axially spaced transversed slots, both above and below the conveyor, toward the conveyor belt and food cooking thereon. Spent gasses are then deflected away from the conveyor belt into a recirculation path, and are reheated in this return path prior to recirculation in a further cycle. 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.

  • Patent number: 5702245
    Abstract: A processing apparatus, conveyor and method for processing products or materials, such as food processing equipment or methods, is configured such that the conveyor travels in a generally helical path within a processing chamber to expose products on the conveyor to a gaseous processing media such as heated or cooled air. The conveyor includes gas flow compensation including a plurality of gas flow compensation members which partially block a portion of the surface of the conveyor, preferably toward the exterior of the conveyor in the helical path, to deflect or direct more of the gaseous food processing media away from the less densely distributed products or materials at the exterior of the conveyor caused when the conveyor follows the helical path. The processing media is thus preferably forced in the direction of the more densely distributed products toward the interior of conveyor to uniformly expose product on the conveyor to the processing media.

  • Patent number: 5657686
    Abstract: The invention describes a method and apparatus for controlling the temperature of the floor of a cooking oven by utilizing a recirculating primary heat transfer fluid made to flow through a heat exchanger located in an oven floor. After traveling through the oven floor and absorbing heat, the primary fluid travels to an external liquid-to-liquid heat exchanger wherein the primary fluid transfers heat to a secondary circulating heat transfer fluid. The primary fluid is then recirculated through the oven floor to maintain the floor at a predetermined temperature. The heated secondary fluid may then be utilized for other processes such as in the conveyor belt washing tank of the oven, or it may be discarded. The primary heat transfer fluid may be a thermal oil having a boiling point substantially in excess of 212.degree. F., and having other properties designed to prevent the corrosion, plugging, and fouling of the heat exchanger located in the oven floor. The second fluid is preferably water.

  • Patent number: 5613594
    Abstract: The present invention relates to an apparatus and a method for treating a conveyor belt with a treatment fluid while minimizing the amount of over spray of the treatment fluid into the air and onto the surrounding equipment and materials. For example, a pervious conveyor belt used in the cooking or other processing of food may be washed, scrubbed, or rinsed with water or a mixture of soap and water without causing overspray of the cleaning or rinsing fluid. Also, the apparatus and method may be used to spray a high quality non-stick coating onto the pervious conveyor belt without over spray of the non-stick coating onto surrounding plant equipment and materials. Overspray is minimized by the placement of treatment fluid flow diverters at the conveyor belt entrance and exit to divert the flow of treatment fluid away from the entrance and exit.
