摘要： 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.

摘要： 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.

摘要： A process for heating articles includes sequentially passing loaded carriers in a continuous manner through a first processing section and sequentially passing said plurality of loaded carriers in an incremental manner through a second processing section using an incremental convey segment. The incremental convey segment includes sequential carrier-receiving slots, each carrier-receiving slot configured to receive one of the loaded carriers. The incremental convey segment is further configured to be move incrementally at multiples of discrete intervals corresponding to the carrier-receiving slots. The process further includes sequentially passing the loaded carriers in a continuous manner through a third processing section and heating articles supported by the carriers with microwave energy in at least one of the processing sections, the heating of the articles occurring while the articles are at least partially submerged in a liquid bath and at an pressure greater than atmospheric pressure.

摘要： Provided herein are a microwave retort system and a process for heating food products using a microwave retort system, such as to pasteurization and/or sterilization temperatures. Food product formulated for treatment in microwave retort processes are also provided. In one aspect, the microwave retort system includes a microwave zone having one or more microwave temperature sections in which a liquid medium is maintained at a temperature below sterilization temperatures during the microwaving process. The processes and systems described herein heat the products to pasteurization or sterilization temperatures while preventing the products, including outer surfaces, reaching a temperature greater than 135° F. The microwave retort processes and systems advantageously provide products with the taste and organoleptic properties equivalent to or nearly equivalent to an otherwise identical freshly prepared product and significantly better than otherwise identical food products that have undergone a conventional immersion or saturated steam retort process.

摘要： A process for heating articles in a heating system includes passing an article in a carrier through a heating chamber that is at least partially filled with a liquid medium to form a liquid bath. The process further includes heating the article in the carrier by at least partially submerging the article into the liquid bath during heating, the heating being performed, at least in part, using microwave energy. The process further includes one or more of adding fluid into and removing fluid from at least one location in the heating chamber to maintain a temperature profile across the heating chamber. In one implementation, the temperature of the liquid bath at an inlet area of the heating chamber is at least 10° C. cooler than a temperature of the liquid bath at an outlet area of the heating chamber.

摘要： Methods for pasteurizing or sterilizing liquid or semi-liquid materials in a liquid-filled microwave heating system are described herein. The methods described herein may be used for pasteurizing or sterilizing a variety of different liquids and semi-liquids, including foodstuffs and beverages, as well as medical, pharmaceutical, nutraceutical, and veterinary liquids. Efficient and rapid heating using microwave energy can provide better temperature control, which permits the use of thinner bottles without sacrificing product quality or safety.

摘要： 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.
