  • Patent number: 9301543
    Abstract: A coffee bean roasting machine of the type having a cyclone separator heating chamber and a coffee bean roasting chamber in a recirculating process stream driven by a recirculation fan is operated to air cool the roasted coffee beans in the roasting chamber, to a temperature beneath which the beans give off smoke, while at the same time incinerating smoke removed from the roasting chamber. A purge gate in ducting between the cyclone separator and the roasting chamber is opened to allow the flow of ambient air into and through the roasting chamber while blocking flow out of the cyclone separator, so that ambient air is directed through the roasting chamber. The smoke and any airborne particulate material from the roasting chamber are carried into the heating chamber and through the incineration tube, where they are incinerated. Preferably the system and process are operated automatically by a computer and programming.

  • Patent number: 9149154
    Abstract: Apparatus for holding cooked food transiently in a warm condition pending service of the food, e.g., in restaurant settings, includes a housing structure defining a food holding area, and a heating device positioned adjacent the food holding area to apply radiant warming heat directly to food in the holding area. The housing structure defines a continuous air circulation path with a first portion of the path extending over the heating device and a second portion of the path extending through the food holding area. A fan is disposed outside the food holding area to produce recirculating movement of air in the air circulation path. The combination of direct radiant heating by the heating device and recirculation of air through the food holding area is effective to maintain cooked food against degradation in edibility for a period of time substantially extended beyond the heating of the cooked food alone.

  • Publication number: 20140202444
    Abstract: A heating transfer method and apparatus that has a fixed physical obstruction placed in the air path causing the airflow to cause the airflow to shed into alternating patterns. A column is placed perpendicular to the airflow path to provide an obstruction to the airflow. The cross-section of the column can be round, square or another multi-sided design. The obstruction will affect the velocity and intensity at which the shedding occurs thus, causing motion of the jets to deliver a more uniform cook on the product surface.

  • Patent number: 8779334
    Abstract: An integrated apparatus able to condition a dry low-temperature environment in a baking process includes a baking unit, a drying unit, and at least a dry air introducing part. The baking unit has a heating unit to heat a first room at a baking period. The drying unit includes a dryer for dehumidifying a second room thereof at a dry low-temperature environment-conditioning period by providing the second room a dry low-temperature air. The dry air introducing part located between the first room and the second room is to separate the first room and the second room at the baking period, and to introduce the dry low-temperature air from the second room to the first room at the dry low-temperature environment-conditioning period.

  • Patent number: 8752538
    Abstract: A rotisserie oven with a self-cleaning mechanism in the form of a lifting wash arm. The wash arm is driven to lift and rotate when washing the oven by the action of the pressure from the wash water used therein. By lifting, the wash arm negates the sealing action of fatty build-up around its base which would otherwise impede its rotation.

  • Publication number: 20140151357
    Abstract: A tangential airstream heat shrinking device of plastic film has a chassis, a heating chamber, air blowers, and high-temperature airstream ejectors. The heating chamber is mounted on the chassis and the heating channel is under the heating chamber. The air blowers are mounted to a bottom of the chassis. The high-temperature airstream ejectors are respectively fit into the mounting holes of the heating chamber. Heated air is discharged through a high-temperature airstream discharging opening of the air blade section under a respective high-temperature airstream ejector. A high-temperature airstream discharging opening is located inside the heating channel of the heating chamber. Each high-temperature airstream ejector can be rotationally adjusted so that the high-temperature airstreams are supplied along routes defined by different tangents at different angles along the circumference of a film-packaged article.

  • Patent number: 8735778
    Abstract: A convection oven having a vapor collection system; water injection system; easily accessible electrical components; and a variable-speed, reversible blower. The vapor collection system collects vapor from the cooking chamber during a cooking event, condenses the vapor, and drains the condensed vapor. The water injection system injects water for impact against a blower wheel for dispersion into the air circulating through the cooking chamber. The electrical components are housed within a housing that in a closed position conceals the components and in a closed position exposes the components for easy access. The rotational speed and direction of the variable-speed, reversible blower is controlled during a cooking event according to predetermined speed curves which may include one or more reversal events to achieve more uniform cooking of food. A main controller is programmable via an operator input (e.g., liquid crystal display touch screen) to control operating parameters of the oven.

  • Patent number: 8729429
    Abstract: A heated food storage and display cabinet including a flow inducer and heater arranged in an upper region thereof, the flow inducer being operable to draw air from an upper portion of the cabinet, to direct the air over the heater, and subsequently urge the heated air down the rear wall of the cabinet and across the floor of the cabinet towards the open front of the cabinet. The heated air is subsequently directed upwardly and rearwardly across the open front of the cabinet by an airflow direction member of the cabinet so as to provide a heated air curtain across the open front of the cabinet, and a portion of the heated air is also passed into the cabinet as the heated air moves down the rear wall and across the floor so as to pass over and around packs of food stored therein.
