Publication number: 20130196040Abstract: A method for cooking a product in an electromagnetic oven. In one embodiment product is conveyed to a convection oven. The product is then cooked to a moisture content of between about 3% and about 20%. The product is then conveyed to an electromagnetic oven where the moisture content is reduced to below 2.5%. The combination of the convection oven and the electromagnetic oven reduces the moisture gradient within the product which results in decreased post packaging stress cracks.Type: ApplicationFiled: January 31, 2012Publication date: August 1, 2013Applicant: FRITO-LAY NORTH AMERICA, INC.Inventors: Ramonica GREEN, Ponnattu Kurian JOSEPH, Baninder S.

Patent number: 6344634Abstract: A method of firing ceramic materials involving placing the ceramic material in a microwave heating apparatus having a microwave cavity and subjecting the ceramic material to combination of microwave radiation and conventional heat energy according to predetermined time-temperature profile. The time-temperature profile, ranging from room temperature the sintering soak temperature, comprises a series of target heating rate temperature setpoints and a series of corresponding core and surface temperature setpoints with each of the core and surface temperature setpoints being offset from the target heating rate setpoints a predetermined offset temperature. The method involves continuously measuring the ceramic body core temperature, TC, and the surface temperature TS. Controlling of the microwave power involves adjusting the microwave power in response to a difference between core temperature setpoint and a biased core measured temperature.Type: GrantFiled: November 30, 2000Date of Patent: February 5, 2002Assignee: Corning IncorporatedInventor: John H.

Patent number: 5813133Abstract: Drying a coated substrate which includes magnetic particles includes a condensing surface spaced from the substrate. This creates a longitudinal gap between the substrate and the condensing surface. Liquid is evaporated from the substrate to create a vapor and the vapor is transported to the condensing surface without requiring applied convection. The vapor is condensed on the condensing surface to create a condensate which is removed from the condensing surface. Removal is performed, using more than gravity, without allowing non-uniformities of the condensate film to occur. The magnetic particles are oriented on the coated substrate by subjecting the coated substrate to a magnetic field created at a location outside of the dryer space.Type: GrantFiled: July 7, 1997Date of Patent: September 29, 1998Assignee: Minnesota Mining and Manufacturing CompanyInventors: John D.

Patent number: 5669156Abstract: An article separating and drying system which receives container ends from an infeed station, separates and dries the container ends and the compound applied thereto in a separating and drying station, and passes the articles to an outfeed station. The article separating and drying system includes a magnetic separating assembly which imposes a magnetic field on the container ends passing thereby for similarly magnetizing the container ends causing neighboring ends to repel one another. The magnetic repulsion of neighboring ends produces gaps between the neighboring ends as they move through the separating and drying station. A conveying device is provided to controllably move the container ends through the separating and drying station. An air distribution assembly is provided to deliver air to said separating and drying station and drive the air through the gap between neighboring container ends thereby contacting the liner compound applied to the container ends and removing moisture therefrom.Type: GrantFiled: August 28, 1996Date of Patent: September 23, 1997Assignee: Fleetwood Systems, Inc.Inventor: Miroslav W.
