To provide an apparatus that can gasify a sterilizer containing hydrogen peroxide to produce a gas having a high hydrogen peroxide concentration. The apparatus can stably produce a gas of the sterilizer containing hydrogen peroxide for a long time. A heating surface of a heating body that gasifies the sterilizer is made of chromium. Alternatively, the heating surface of the heating body that gasifies the sterilizer may be made of polytetrafluoroethylene or perfluoroalkoxy fluorocarbon resin, or a chromium plating impregnated with chromium polytetrafluoroethylene or perfluoroalkoxy fluorocarbon resin.

An air composition adjusting device includes: an oxygen separator that separates oxygen from external air to be supplied to a target space; a gas supply path including a high concentration gas supply path for oxygen through which the oxygen separator communicates with the target space; and a controller that performs an oxygen concentration raising operation of supplying a high oxygen concentration gas, which has a higher oxygen concentration than external air before being treated by the oxygen separator, to the target space through the high concentration gas supply path for oxygen.

Food preservation can include depositing dry ice and food within packaging. The packaging can include a flexible liner defining a wall aperture and an internal chamber. The internal chamber can receive the deposited dry ice and food and have an internal atmosphere. The packaging can include a check valve mounted to the flexible liner and covering the wall aperture. The check valve can be configured to occupy: (i) a closed state blocking fluid communication between the internal chamber and ambient via the wall aperture and (ii) an open state enabling fluid flow from the internal chamber, through the wall aperture, and into ambient.

A method and apparatus to decontaminate agricultural products utilizing ozone gas. This invention achieved a 5-log or greater inactivation rate of surrogate organisms through a process of circulating ozone gas uniformly inside a hopper, conveyor assembly, and discharge box. The ozone gas distributes uniformly in the hopper through the operation of an agitator. The ozone gas, created by an ozone generator on-site, bifurcates inside a conveyor tube and distributes uniformly to the agricultural product inside a conveyor tube through the operation of a conveyor and a vibration motor. The conveyor assembly is air tight with safety measures operating to mitigate leakage of ozone gas. These safety measures include an ozone destructor or a perforated tube.

The present invention provides a refrigerator, comprising: an adsorption container, an air compressor and a nitrogen storage tank. A sealed storage space is formed in a storage compartment of the refrigerator. The adsorption container with carbon molecular sieves disposed therein is disposed in the storage compartment. The air compressor is directly connected to the adsorption container through an air inlet pipe and configured to supply compressed air for the adsorption container in a controlled manner so as to allow the carbon molecular sieves to prepare nitrogen by means of the compressed air. A gas inlet end of the nitrogen storage tank is connected to the adsorption container, and a gas outlet end thereof is communicated with the storage space.

Disclosed is a container for shipping agricultural commodities, the container including a generator that generates gas pressure to balance vacuum pressure that accumulates over time in the container.

A continuous flow sterilization system includes an inclined treatment chamber having a first end and a second end. An ozone generator generates a flow gas containing ozone; an input opening to receive a bulk material into the treatment chamber. An input port is provided for introducing the flow gas containing of ozone into the treatment chamber. A first sensor measures a level of ozone in the gas output of the treatment chamber. The other sensors measure ozone concentration and temperature within the treatment chamber. An output opening provides an exit for the bulk material. An output port provides an exit for the flow gas. An auger is disposed within the treatment chamber to move the bulk material through the treatment chamber.

A method for planning preparation of a plurality of dishes according to a plurality of corresponding recipes includes automatically identifying, by a processor, a plurality of candidate sub-recipes, wherein each candidate sub-recipe in the plurality of candidate sub-recipes comprises an intermediate component that is required by at least two of the plurality of corresponding recipes, and automatically selecting, by the processor, at least one candidate sub-recipe in the plurality of candidate sub-recipes for preparation, in accordance with at least one constraint on the preparation of the plurality of dishes.
