[0001] GAS COMPOSITION CONTROL SYSTEM WITHIN A STORAGE DEVICE

[0002] Field of the Invention

[0003] Engineering relates to the gas composition control system within a storage device

[0004] Background of the Invention

[0005] In transporting or storing perishable raw materials such as seeds, grains, food, or any agricultural products, managing the conditions inside the packaging or storing area is one of the key processes, which helps extend the shelf life of raw materials and prevent losses caused by other factors such as insects, fungi, or microorganisms. The commonly used methods to reduce such risk factors include thermal sterilization, which is suitable for creating sterile conditions for raw materials that do not deteriorate when exposed to heat or for preparing packaging before storing such raw materials; temperature control within storage facilities to prevent the growth of living organisms such as insects or microorganisms; or the use of chemical agents toxic to living organisms for spraying or coating such raw materials during storage. The chemicals commonly used for coating or fumigating agricultural products to prevent insects include phosphine and methyl bromide which are highly toxic and can easily decompose, resulting in minimal residue levels of these substances in perishable raw materials, making them safe for consumption.

[0006] Because the ease of decomposition of such chemicals, it is necessary to regularly coat or fumigate perishable raw materials with these substances to ensure that living organisms that may damage the perishable materials cannot grow or survive. This method, however, can lead to fumigant resistance, resulting in the need to continually increase the concentration of chemicals used in fumigation.

[0007] Currently, alternative methods have been developed to control the conditions inside storing areas or packaging to create an environment unsuitable for the growth of insects, fungi, or microorganisms that may damage such perishable raw materials. For example, storing perishable raw materials under specific temperature conditions. However, this method still has limitations due to the wide range of temperatures at which insects, fungi, or microorganisms is possibly grow. Additionally, excessively low temperatures may damage the structure of certain raw materials, leading to quality degradation. For instance, the deterioration of the starch structure in perishable raw materials can result in changes in texture and taste.

[0008] In addition to temperature control, a review of patent databases has revealed patents related to the storage of perishable raw materials that involve controlling the environment within the storage area to extend the shelf life of such raw materials, including: Thai invention patent application number. 2201001372, titled “Storage Component Kits for Storing Perishable Objects,” has describes a packing box and the assembly of such a box for use in storing perishable raw materials. The packing box comprises a base that modified for lifting with a platform lifter to place the perishable raw materials on top, and a cover consisting of top and side walls are sized to enclose and surround the perishable objects on the base. The box also includes a sealing component to prevent air leakage into the packing box.

[0009] Chinese patent publication number. CN1 1 0482499 A, titled “Special Nitrogen- Oxygen Separator for Vacuum Nitrogen-Charging Insect-Killing Sterilization Equipment,” has describes a nitrogen and oxygen separator for supplying nitrogen to eliminate insects. It consists of a nitrogen and oxygen separation tank, which internally includes an oxygen separation tank and a carbon molecular sieve. The carbon molecular sieve packing contains carbon molecular particles. Air is compressed by an air compressor into the nitrogen and oxygen separation tank through an air intake pipe. The pressure is maintained for one minute to allow the carbon molecular sieve to fully absorb the oxygen gas. Subsequently, the control system commands the opening of an electromagnetic valve on the nitrogen discharge pipe, allowing nitrogen to enter the nitrogen storage tank. Afterward, the valve is closed, and the valve on the nitrogen and oxygen separation tank is opened to reduce the tank pressure, causing the oxygen gas adsorbed on the carbon molecular sieve to be released. Then, the control system commands the opening of the electromagnetic valve on the oxygen discharge pipe to allow oxygen to enter the oxygen storage tank, completing the nitrogen and oxygen separation process.

[0010] Chinese patent publication number. CN 1 1 5735868 A, titled “Insect Killing System for Stored Tobacco Leaves and Storage Method,” has describes an insect controlling system for storing tobacco leaves, which are stored in warehouses in the form of tobacco leaf piles. The insect control system comprises a nitrogen production unit, a control unit, a detection unit, and an adjustment unit. The detection unit is connected to the control unit to monitor variables related to the environment inside the tobacco leaf pile. The control unit is connected to the adjustment unit to modify the conditions inside the tobacco leaf pile according to temperature and humidity. The storage of tobacco leaves includes the sealing step, then the nitrogen filling step to reduce the oxygen concentration within the tobacco leaf pile to below a predefined threshold. Then the storage step comprises that the control unit monitors the conditions inside the tobacco leaf pile and commands the adjustment unit to ensure the internal conditions meet the predefined criteria.

[0011] In the first patent, it mentions a packing box designed to prevent air leakage into the box but does not include a system for controlling the conditions inside the packing box. In contrast, the Chinese patents publication number. CN110482499A and CN115735868A, disclosed the systems for controlling conditions inside storage areas, such as humidity and temperature, combined with the use of nitrogen gas to prevent insect growth or eliminate insects in enclosed spaces.

[0012] There is no mention of controlling the conditions or gas composition within the enclosed storing area, combining with the monitoring to detect abnormalities, such as air leakage or the rate of humidity increase, which could affect the deterioration of perishable raw materials. Additionally, there is no mention of utilizing a condition control system in combination with sealed storage devices or packaging to prevent exposure to external air and moisture, such as airtight boxes or hermetic bags. In contrast, this invention discloses the development of a system for controlling conditions within storage areas, with the capability of monitoring or inspecting the conditions within these areas. The storage devices or packaging are designed to be sealed, allowing for timely tracking and resolving of errors in cases where the storage device or sealed packaging is damaged or if errors occur during the packaging of any raw materials.

[0013] Summary of the Invention

[0014] The gas composition control system within a storage device, as described in this invention, comprises a storage device connected to an air control unit which includes at least a monitoring unit comprises a composition sensor, an air pressure sensor, and a control unit connected to the monitoring unit to analyze the conditions inside the storage device. The control unit is also connected to a quality improvement unit, which includes at least a nitrogen gas generator and a vacuum pump to adjust the internal conditions of the storage device according to predefined criteria.

This data is received by the command data receiving unit (233) in cooperation with the user interface unit (231), which directs the preparation unit (235) to execute the fumigation process steps.

[0057] The change monitoring unit (236) generates real-time alerts if the condition data inside the storage device, as measured by the measurement unit (220), does not comply with the predefined criteria.

[0058] The display unit (237) receives display request commands from the command data receiving unit (233), retrieves the necessary data from the memory unit (232), and prepares it for display. The data is presented in the form of tables, graphs, charts, or electronic reports, which are shown to the user through the user interface unit (231).
