摘要： Systems and apparatus are provided for maintaining an ultra low oxygen concentration in a shipping container for the purpose of preventing spoilage of perishable food products. The system and apparatus may contain a composition of a mixture of gases including one or more of nitrogen, carbon dioxide, and another inert gas, wherein the mixture of gases positively pressurizes the shipping container with an ultra low oxygen concentration. The system and apparatus may use one or more sensors to monitor the composition of the mixture of gases, and may use one or more controllers to release the compressed gases into the interior of the container. The controller may release the compressed gases at a variable rate of release sufficient to maintain the ultra low oxygen concentration and to ensure consistent concentrations of the mixture of gases with the container.

摘要： A device for controlling package pressure and gas flow for a packaged good comprises a film having a first opening for exposure to the inside of a package and a second opening for exposure to the outside of a package. A channel extends between the first opening and the second opening. The dimensions of the channel are configured to control the rate of flow of CO2 (cc/min @ 1 PSI) from the inside of the package to the outside of the package and control the oxygen transmission rate (cc/day/Atm) from the outside of the package to the inside of the package so that a flow of CO2/OTR ratio is at an acceptable level for the packaged good.

摘要： A method for the preservation of fresh plants by vacuum pre-cooling synchronously combined with modified atmosphere technique includes: (1) screening field-picked fresh plants, and selecting individuals with uniform size, consistent maturity, and no obvious defects; (2) placing the screened individuals in a vacuum pre-cooler for pre-cooling; (3) after the plants are pre-cooled to the final temperature, the device automatically shuts down the refrigerator and vacuum pump, and the pre-configured mixed gas is introduced from the intake air inlet into the vacuum chamber for re-pressing; and (4) taking the re-pressed fresh plants out of the pre-cooler, and performing modified atmosphere packaging and refrigerating. A specific mixed gas can be filled during the vacuum pre-cooling and re-pressure stages, and the re-pressure process after pre-cooling is closely integrated with the modified atmosphere technique to reduce the respiration metabolism of the plant to a suitable low level, significantly prolonging the shelf life of the product.

摘要： A gas-selection device for a sealed storage container with modified or controlled atmosphere, remarkable in that it includes a hollow body and at least one first orifice, a second orifice and a first membrane, said first and second orifices connecting the inside of said body to the outside, said first membrane being disposed inside said body between said first and second orifices so that the gases flowing from the first orifice to the second orifice, or vice versa, necessarily and solely pass through said first membrane, and in that the device is arranged so as to be secured sealingly to one of the walls of the container, so as to allow a flow of gas from its second orifice through the wall, or vice versa.

摘要： Atmospheric control valve device, part of an atmospheric control system built into a refrigerated container, whose installation requires minimal intervention and is self-sufficient, compact and reusable due to its long, cylindrical body that includes a battery compartment. The body also has a compartment for the electrical, electronic and sensor elements; a handling compartment for the elements that handle the device; a cover area to cover the container after removing the device; and a gas exchange compartment for two-way gas exchanges, controlled by a solenoid valve and by the differences in pressure that occur naturally within the refrigerated container.

摘要： A method for controlling an atmosphere in a space which is at least partially filled with agricultural or horticultural products comprises the steps of (a) measuring an amount of at least one metabolite such as acetaldehyde, ethyl acetate and/or ethanol produced by the products, (b) measuring at least one of (i) an amount of oxygen absorbed by the products and (ii) an amount of carbon dioxide produced by the products, (c) determining a relationship between the measured amount of the metabolite and the measured amount of oxygen and/or carbon dioxide, (d) analyzing the determined relationship to detect a potential onset of fermentation in the products and (e) selectively adjusting a level of at least one component of the atmosphere in the space on the basis of the analysis. An installation for carrying out this method is also claimed.

摘要： An apparatus and method for microwave vacuum-drying of organic materials, such as food products. The apparatus has a microwave vacuum chamber 20, a loading module 36 to load containers 38 of the organic material into the vacuum chamber, a rotatable cylindrical cage 64 in the vacuum chamber for rotating the containers, a piston 114 for moving the rotating containers through the vacuum chamber, and means for unloading the containers of dehydrated material from the vacuum chamber. The apparatus may include an equilibration chamber 150 for cooling the dehydrated material under reduced pressure, and a transfer module 42 to transfer the containers from the vacuum chamber to the equilibration chamber. The apparatus has a microwave transparent window 54 for transmission of radiation into the vacuum chamber, and a gas jet 58, 60, 62 for blowing a stream of gas, such as air or nitrogen, into the vacuum chamber adjacent to the window.

摘要： A control system for a controlled atmosphere room (“CA room”) for storing perishable commodities, such as fruits and vegetables. The control system includes an enclosure that can be placed within the CA room to store a representative sample of the commodities in the CA room. The control system includes an atmosphere valve selectively operable to provide atmospheric communication between the enclosure and the CA room or to isolate the enclosure from the CA room. The control system includes a sampling control system for determining a dynamic control value based on the isolated representative sample. The dynamic control value may be determined by monitoring the respiratory quotient in the enclosure while it is isolated. Once determined, the control system can use the dynamic control value to adjust the atmosphere of the CA room, thereby using tests on a representative sample to control the atmosphere for the full volume of commodities in the CA room. When not testing, the enclosure generally remains in atmospheric communication with the CA room, which improves the correlation of the representative sample with the commodities in the CA room.

摘要： Disclosed is a container refrigeration apparatus including a unit case of an inside air control system disposed outside a container, the unit case housing an air pump therein. The container refrigeration apparatus is provided with an air inlet unit independent of the unit case. The air inlet unit and the air pump are connected together by a tube. The air inlet unit is provided with a membrane filter, and is disposed above the unit case. Malfunctions of electrical components and corrosion on metallic components due to moisture permeation into the unit case are reduced.
