The present disclosure relates to novel microwave systems and new applications of microwave in medical, chemical and materials manufacturing and processing, food and health industries as well as in analytical chemistry instrumentation for in situ study of microwave effects. In the case of medical applications, the microwave based damage is conducted in a way to diminish ablating or damaging the collateral tissue and to increase the probability of procedure achievement.

The present invention relates to a processing apparatus, in which a dairy product is heated, dried, disinfected and/or pasteurized, sterilized. The present invention further relates to a method to treat a dairy product with radio-frequency wave

A cooling apparatus that cools a cooling target object in a state in which an electromagnetic field or an electric field acts on the cooling target object and that is capable of efficiently causing a subcooling state of the object is provided. The cooling apparatus includes a refrigeration machine to cool an cooling target object, an electromagnetic wave irradiation device to generate an electromagnetic field which acts on the cooling target object and intensity of which is variable, a controller to control operations of the refrigeration machine and the electromagnetic wave irradiation device and perform a subcooling operation of cooling the cooling target object by using the refrigeration machine in a state in which the electromagnetic field is generated, and a temperature sensor to measure a temperature of the cooling target object. In the subcooling operation, the controller controls the intensity of the electromagnetic field generated by the electromagnetic wave irradiation device in accordance with the temperature measured by the temperature sensor.

Embodiments herein relate to systems and methods for thermally processing packaged food products with highly-uniform electromagnetic energy fields. In an embodiment, a method of thermally processing a packaged food product is included herein. The method can include placing the packaged food product in a heating chamber, the packaged food product comprising a hermetically sealed package and a food material disposed within the package. The method can further include applying electromagnetic energy to the packaged food product from a first electromagnetic energy source from a first direction. The electromagnetic energy can be sufficient to raise the temperature of the food material by at least 50 degrees Fahrenheit with a spatial temperature variation of less than 25 degrees Fahrenheit in less than 120 seconds. Other embodiments are also included herein.

An in-shell egg pasteurization process includes, in a temperature-raising stage (12), raising the temperature of yolk of a plurality of in-shell eggs (40), simultaneously and at least predominantly by means of microwave radiation, to a pasteurization temperature, the temperature-raising stage (12) including a plurality of elongate or longitudinally extending microwave cavities that are isolated from one another so that microwaves fed into an elongate or longitudinally extending microwave cavity do not leak into any other elongate or longitudinally extending microwave cavity. The in-shell eggs (40) are displaced along the lengths of the elongate or longitudinally extending microwave cavities whilst being irradiated with microwaves. In a pasteurization stage (14), the raised temperatures of the in-shell eggs (40) are maintained for a pasteurization time sufficient to pasteurize the in-shell eggs (40).

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.

A method for processing vegetables to reduce unpleasant odor and/or taste, and/or to minimize discoloration, deterioration, degradation, or rot over a period of storage time is described. The method includes: i) subjecting the vegetable to mechanical size reduction; ii) heating or freezing the vegetable for a pre-determined period; and iii) bringing the softened vegetable product into contact with one or more reactive oxygen species selected from: peroxides; superoxides; and ozone.
