The method for producing dinitrogen tetraoxide comprising the steps of operating a decompressor (3) to reduce a pressure within the space area (2) maintained in the hermetically sealed condition to the decompressed or vacuum condition below the saturated vapor pressure curve of dinitrogen tetraoxide, supplying the dinitrogen tetraoxide liquid as a sterilant feedstock from a vessel (4) to a spray device (25) while preventing gasification of the dinitrogen tetraoxide liquid on the way between the vessel (4) and spray device (25), and spraying the dinitrogen tetraoxide liquid through the spray device (25) into the space area (2) under the decompressed or vacuum condition to, at the time of the spraying, gasify at least some of the dinitrogen tetraoxide liquid within the space area (2) decompressed below the saturated vapor pressure curve.

A system for conserving oxygen and other gasses supplied to a recipient. A supply conduit supplies gas from a source to a reservoir, which retains a volume of gas at ambient pressure. A conduit supplies gas from the reservoir to the recipient, and an inflation detection system detects when the reservoir is below a state of inflation and when the reservoir is inflated to the state of inflation. A valve system prevents gas from flowing from the source and into the reservoir when the reservoir is at the predetermined state of inflation, and the valve system permits gas to flow from the source and into the reservoir when the reservoir is below the predetermined state of inflation whereby gas within the reservoir can be continually replenished without pressurization above ambient pressure. The inflation detection system can be an electro-mechanical system. Alternatively, the inflation detection system can be a contactless system.

As disclosed herein, a preservation system for perishable products in a display case comprises a control valve for connection to a water supply. A pressure regulator is connected to the control valve for reducing water pressure. A plurality of piezoelectric transducer nebulizers are operatively mounted to the display case in spaced apart relation to one another and are fluidically connected in series with an output of the pressure regulator to emit a dry fog. A control system comprises a controller for controlling a duty cycle of a pulse signal to vibrate the piezoelectric transducers in the plurality of nebulizers, and a timer for alternately generating an on and an off signal to periodically control the valve to supply water to the pressure regulator and to enable the controller whereby the nebulizers emit the dry fog to maintain desired relative humidity level throughout the display case.

An oven for food use comprising a cooking chamber and a device for smoking and/or flavoring foodstuffs that includes at least one container capable of being placed inside the cooking chamber and able to contain substances suitable for generating smoke for smoking and/or vapors for flavoring as well as a heat source provided for transferring heat to said substances for the purpose of smoking and/or flavoring the foodstuffs, the oven comprising at least one temperature sensor provided for detecting the temperature of the substance in the container.

An oven for food use comprising a cooking chamber, at least one variable-speed electric fan, the rotation of which is controlled by an electric motor, and a device for smoking and/or flavoring foodstuffs, the device comprising at least one container capable of being placed inside the cooking chamber and able to contain substances suitable for generating smoke for smoking and/or vapors for flavoring as well as a heat source provided for transferring heat to said substances for the purpose of smoking and/or flavoring the foodstuffs. The heat source comprises at least one electrical resistance element provided inside the cooking chamber, which element is part of the electrical circuit supplying the motor of the electric fan and is provided so as to be selectively connected to or disconnected from the electrical circuit in order to vary the speed of the fan after power is supplied to the resistance element.

A method for decontaminating articles having porous outer surfaces. The method includes steps of: providing a decontamination chamber; conveying the articles through the decontamination chamber at a predetermined speed wherein the speed is selected such that the articles are disposed in the decontamination chamber for a predetermined period of time; providing a source of sterilant vapor, the source providing the sterilant vapor at a temperature within a predetermined acceptable temperature range and at a concentration within a predetermined acceptable concentration range; conveying a sterilant vapor from the source of sterilant vapor to the decontamination chamber; and exposing the articles to the sterilant vapor. The predetermined period of time and the predetermined acceptable concentration range of the sterilant vapor are selected such that the sterilant vapor does not penetrate the porous outer surfaces of the articles.

A packaged product which comprises a solid object and a packaging that seals and holds the solid object, wherein a replacement gas is contained in a space sealed by the packaging when the packaging is sealed and wherein the solid object has absorbed a part of or all of the replacement gas.

Material and methods are disclosed involving the generation and containment of solutions incorporating reactive precursors and reactive treatment agents. Formulations of these materials can be applied widely as disinfectants, odor control agents, decontamination and fumigation agents, liquid, gas, and air treatment materials, respiratory agents, food and beverage processing agents, neutralization agents, and in many industrial, residential, medical and military surface treatment operations.

Electrochemical processes and systems for preserving perishable food are described. The process and system allow for the preservation of perishable food in the presence of water moisture, melanin, or a precursor, derivative, analog, or variant of melanin, and electromagnetic energy, such as visible or invisible light energy. There exists a need in the art for improved methods and processes for preserving perishable foods that overcome certain disadvantages associated with known methods for preserving perishable food, such as addition of preservatives, refrigeration/freezing, drying/dehydration of food, and storage under vacuum. The invention satisfies this need by providing a process and system for preserving perishable food in the presence of water moisture, electromagnetic energy, and melanin, melanin precursors, melanin derivatives, melanin analogs, or melanin variants.

The subject matter described herein relates to systems for treatment of a product for decontamination of the product. The product may include agricultural, food and related product. The system comprises a decontamination chamber (102, 102-1) having an inlet (120, 120-2) to receive the product; multiple first channels (143, 202, 302, 402, 602, 702) in the decontamination chamber (102), wherein the multiple first channels (143, 202, 302, 402, 602, 702) are distributed across the longitudinal span of the decontamination chamber (102, 102-1); a trioxygen generator (106) with a feedline (128) coupled to the multiple first channels (143, 202, 302, 402, 602, 702), wherein the trioxygen generator (106) is to provide trioxygen gas to the multiple first channels (143, 202, 302, 402, 602, 702) to disseminate trioxygen gas onto the product in the decontamination chamber (102, 102-1); and an outlet (145, 145-2) to output the trioxygen treated product.
