  • Patent number: 11674941
    Abstract: Sensor stations and related systems and methods to monitor and measure properties of food products in food processing structures such as cure rooms, smokehouses, ovens, and related structures. The sensor stations allow real-time, local collection of product properties and their surrounding environmental conditions in order to improve efficiency, reduce product waste and guesswork, and to provide data-based analysis for decision making. Sensor stations can be mounted to food supports and can be in electronic communication with each other and with intermediate nodes that provide a connection to other external computing devices that provide analysis and alerts to users and technicians. Various non-destructive modeling systems for determining water activity and pH of changing products are also provided.

  • Patent number: 8847130
    Abstract: A heating unit can reduce the rate of power consumption for heating a vehicle, so that the running distance of the vehicle is increased and hence the battery charging cycle of the vehicle is prolonged. A heating unit of a vehicle heating system includes a casing made of a metal material capable of electromagnetically shielding microwaves, a support arranged in the hollow section of the casing, a plurality of microwave absorbing/heat emitting members arranged at the support and a microwave outputting unit arranged in the casing to output microwaves toward respective microwave absorbing/heat emitting members, blown air being heated by heat generated as a result of absorption of microwaves by the microwave absorbing/heat emitting members at the time for blown air to flow from the upstream side to the downstream side in the hollow sections of the microwave absorbing/heat emitting members.

  • Patent number: 8586898
    Abstract: The invention described herein pertains generally to a more efficient and cost-effective method and apparatus for: (1) coupling of microwave energy from a microwave generator or plurality of microwave generators into an integral set of applicators; (2) extraction and separation of organic compounds from a mixture of organic and inorganic compounds; and (3) recovery and conversion of the organic compounds to gaseous and liquid fuels. The apparatus described in this invention result in improved microwave absorption within the mixture flowing through the applicators by increasing residence time within the applicators, resulting in a higher temperature within the material. The higher temperature lowers the viscosity of the solution, but also provides a limited reduction of the combination of complex chain and aromatic organic compounds to allow recovery of syngas and fuel oil.

  • Patent number: 8294070
    Abstract: A cooking appliance includes a recirculating airflow which is directed through particularly configured air plenum and nozzle structure that synergistically combine to enhance an overall cooking efficiency and effectiveness. In particular, the configuration of the air plenum, as well as the sizing and distribution of oven cavity entry nozzles, provides for an enhanced flow of heated air to the food product, thereby resulting in short cooking times due to high heat transfer while also providing an even browning and crisping of the food item being cooked. In addition, the cooking appliance incorporates an exhaust system wherein cooling air and a percentage of the recirculating airflow are mixed prior to being exhausted from an angled exhaust mixing tube.

  • Patent number: 5514853
    Abstract: An apparatus assembly for heating a product has a tunnel and microwave generators positoned for generating a microwave field zone within the tunnel. A conveyor belt extends within the tunnel for passing a product through the tunnel. A plate formed of a material impermeable to microwaves is positioned in the tunnel so that an entire width of the belt passes over the plate in the microwave field zone so that microwave energy is reflected away from the belt. In addition, heating elements for generating an infrared energy zone and a further conveyor belt may be positioned so that a product passed through the tunnel then is passed by the further conveyor belt through the infrared energy zone.
