Patent number: 10966293Abstract: Processes and systems that enhance the heating of packaged foodstuffs and other items in various microwave heating systems are described herein. It has been unexpectedly found that configuring the microwave heating zone of a microwave-assisted pasteurization or sterilization system so that the article carrier, the microwave launchers, and/or the packages have certain relative dimensions may significantly enhance the uniformity of heating of the articles. The result is pasteurized or sterilized articles that exhibit fewer hot and cold spots, a consistent microbial lethality rate, and desirable end properties, such as visual appearance, taste, and texture.Type: GrantFiled: April 16, 2018Date of Patent: March 30, 2021Assignee: 915 Labs, LLCInventors: Matthew Raider, David Behringer, Li Zhang, Harold Dail Kimrey, Jr.

Patent number: 10638557Abstract: Carriers suitable for transporting a plurality of articles through a microwave heating zone are provided. Carriers as described herein may include an outer frame and upper and lower support structures vertically spaced from one another to provide a cargo volume into which the articles are loaded. At least a portion of the upper and/or lower support structures may be formed of an electrically conductive material. Additionally, the carrier may include removable article spacing members, such as vertical spacing members and dividers, that can be selectively inserted to adjust the size and/or shaper of the cargo volume. Carriers as described herein may be configured to receive a variety of different articles, including trays and pouches, and the articles may be loaded into the carrier in a nested or overlapping manner.Type: GrantFiled: October 3, 2016Date of Patent: April 28, 2020Assignee: 915 Labs, LLCInventors: Harold Dail Kimrey, Jr., Caleb Samuel Bales, Matthew Raider, David Behringer

Publication number: 20200000947Abstract: Systems and methods including modular electromagnetic heating systems enable heating of articles using electromagnetic energy. The systems include a primary processing vessel equipped with electromagnetic energy launchers and fluid delivery systems to enable capable of preheating, heating, and cooling of the articles within the primary processing vessel. The primary processing vessel is further configured to be coupled to one or more upstream or downstream vessels such that portions of the preheating and/or heating functionality may instead be performed by the additional vessels. This flexibility enables scaling of the electromagnetic heating system between a relatively small (e.g., lab) scale system and a relatively large (e.g., production) scale system while minimizing capital expenditures and space requirements.Type: ApplicationFiled: June 28, 2019Publication date: January 2, 2020Applicant: 915 Labs, LLCInventors: Lora N. Spizzirri, Moses A. Magana, Matthew J. Raider

Patent number: 10448465Abstract: A microwave heating system configured to heat a plurality of articles and a process for using the same is provided. The heating system includes at least two laterally-spaced parallel convey lines and two or more groups of microwave launchers configured to heat articles transported along each convey line. The groups of microwave launchers can include pairs of oppositely disposed launchers that are spaced apart from one another along the axis of convey. When the system includes multiple convey lines, adjacent launcher groups are staggered relative to one another in the convey direction. Heating articles, such as foodstuffs or medical fluids or equipment in such a system, minimize undesirable interference between launchers of adjacent groups and provide a more uniform heating field.Type: GrantFiled: June 27, 2016Date of Patent: October 15, 2019Assignee: 915 Labs, LLCInventors: Harold Dail Kimrey, Jr., Robert Brian Wilson

Publication number: 20190274195Abstract: A method for processing articles using a microwave heating system includes obtaining an operating profile for heating a type of article using the microwave heating system. The operating profile includes a temperature-time profile for a target F0 value and a group of set point values for achieving the temperature-time profile, the group of set point values including a target for a control parameter of the microwave heating system. Using a control system operatively coupled to the microwave heating system, the microwave heating system is operated in accordance with the group of set point values such that each of the articles achieves an F0 value that is greater than or equal to the target F0 value.Type: ApplicationFiled: March 1, 2019Publication date: September 5, 2019Applicant: 915 Labs, LLCInventor: Moses Alexander Magana
