Method and system for treating packaged products

A system and method for decontamination of product is described. An object to be treated, which may be a food product or a medical device, is placed in a substantially closed dielectric container with a working gas. The container is placed in an apparatus capable of producing a controlled electrical discharge so as to create reactive ion species within the package. The object to be treated may be exposed either the immediate products of the electrical discharge or the long lasting reactive ion species, or both, so as to treat the object to reduce or eliminate specific contaminants, which may be biological pathogens or the cause of product spoilage, or inorganic contaminants. The reactive ion species may result from an atmospheric non-equilibrium plasma (ANEP) formed by the apparatus and the treatment may be performed without significantly increasing the bulk temperature of the object being treated.

SYSTEM AND METHOD FOR INFRARED DEHYDROFREEZING AND DEHYDRO FREEZE-DRYING
20250185677 · 2025-06-12 ·

The present invention is directed to a method for combining dehydrofreezing and medium to far spectrum infrared radiation to preserve biological material. IR transfers energy and penetrates food products, thereby removing naturally present moisture. The present invention provides a novel method of combining pH treatment, infrared radiation, freezing, and vacuum-sealing for preserving biological material. Biological materials are preserved through either a pH treatment or with heat to remove harmful pathogens, followed by processing using far spectrum infrared radiation which may be powered by either gas or electric means. The processed materials undergo a freezing process which may be done using Individual Quick Freezing or blast freezing methods The frozen processed material is then packaged via vacuum sealing.

MICROWAVE AND INFRARED HEATING SYSTEM AND METHOD FOR FRUIT AND VEGETABLE ENZYME DEACTIVATION
20250295130 · 2025-09-25 · ·

A method for enzyme deactivation in raw produce involves a computer-controlled two-step heating process using microwave and infrared systems. Initially, a monolayer of raw produce is conveyed through a microwave oven, maintaining relative humidity below a threshold, to achieve a first average temperature. Subsequently, the produce is transferred to an infrared oven, where the relative humidity is kept above the threshold, resulting in a second average temperature that is equal to or greater than the first. The method ensures efficient enzyme deactivation by adjusting the respective depth of produce monolayers, the intensity and duration of microwave and infrared exposure, and controlling temperature and humidity levels during the heating process.
