By sealing gas for food packaging, it contributes to improving quality by preserving flavor and preventing oxidation. When packaging food, removing the air inside the packaging and replacing it with gas allows for the retention of essential elements such as taste, nutritional value, color, and aroma, ensuring the freshness of the product. ■ Quality Improvement It maintains freshness by expelling oxygen around the food and slowing down oxidation reactions. ■ Planned Production and Sales Extending the product's shelf life improves yield. Using nitrogen and carbon dioxide gases, which are harmless to the human body, can help prevent oxidation, inhibit bacteria, and deter pests. ■ Stable Supply of Various Gases We have manufacturing and filling plants across the country, providing a robust supply system, including related companies. We ensure stable supply in the optimal form based on mixing ratios and usage amounts. We can accommodate suitable responses such as pre-mixing or on-site mixing according to usage forms. ■ Solving Food Waste/Disposal Issues Extending the shelf life helps improve the issue of mass disposal of bread. Commitment to the SDGs (Sustainable Development Goals).

Nitrogen stripping, also known as gas replacement degassing, is a technology involving partial pressure and gas-liquid contact. By installing a stripper in the process piping and introducing high-purity nitrogen gas, it is a system that efficiently removes dissolved oxygen from process water. 【Features】 - High-efficiency deoxygenation is possible. High-purity nitrogen allows for deoxygenation in the PPB order. - Compared to other methods, the equipment cost is low, and operation is simple. It can be easily installed in existing piping. - Maintenance is easy. There are no moving parts, and it is designed to be sanitary for food applications. - Nitrogen can be widely used in atmosphere control. It can be combined with purging, blanketing, and pressurization. 【Examples of Applications】 - O2 removal from edible oils (soybean oil, corn oil, vegetable oils, etc.) - O2 removal from potable water (beer, juice, tea water, etc.) - O2 removal from fatty acids - O2 removal from chemical process water - H2O and O2 removal from chemical raw materials (resins, solvents, etc.) For more details, please contact us.

The MIXFLO system is a simple oxygen dissolution system that can be retrofitted to existing open aeration tanks. It dissolves oxygen with an efficiency of over 90%, making it a highly efficient wastewater treatment system that can improve the processing capacity of wastewater treatment facilities. 【Features】 - The system can be easily implemented by simply adding it to existing facilities. It consists of a simple piping system, and minimal modifications to the existing setup are required. - Installation can be completed in a short period while the aeration tank is in operation. Typically, installation can be carried out without draining the aeration tank. - It enables low-cost treatment with an oxygen dissolution efficiency of over 90%. The system is designed optimally according to the required oxygen amount, utilizing oxygen gas without waste. - Exhaust gas and splashing are significantly reduced, allowing for clean treatment. Since most of the oxygen dissolves, the amount of exhaust gas is reduced to about 1/1000th of that of air aeration. For more details, please contact us.

The "Oxygen Fighter" and "MIXFLO" are oxygen dissolution systems designed for wastewater treatment that efficiently dissolve oxygen gas into liquids, enhancing the processing capacity of aeration tanks. Simply attaching them to existing aeration tanks can easily improve processing capacity, especially with "MIXFLO," which can increase it by up to three times. Additionally, the "Oxygen Fighter" allows for easy enhancement of oxygen dissolution amounts, and demo units are available for loan. If you are interested, please feel free to contact us. 【Features】 ■ Easily enhance oxygen dissolution amounts ■ Strong resistance to fluctuations in pollution load ■ Reduction of excess sludge (10-20%) *For more details, please download the catalog or contact us.

Nitrogen stripping, also known as gas replacement deoxygenation, is a technology that involves partial pressure and gas-liquid contact. By installing a stripper in the process piping and introducing nitrogen gas, this system efficiently removes dissolved oxygen from process water. Nitrogen gas is an inert gas that is tasteless and odorless, and it has low solubility in water, so it does not affect the product. It is effective for removing oxygen from edible oils such as vegetable oil and soybean oil, as well as beverages like beer and juice. 【Features】 ■ High-efficiency deoxygenation possible ■ Easy maintenance ■ Low equipment cost and simple operation ■ Nitrogen can be widely used for atmosphere control and more *For more details, please download the PDF or contact us.

Our company is a gas and energy company. We would like to introduce industrial air separation gases "oxygen, nitrogen, and argon" that are separated from the air. 【1. Nitrogen Gas】 It makes up about 80% of the air and has the characteristics of being a liquid at -196°C and being an inert gas. It is widely used for purposes such as freezing food, preventing oxidation, and cooling metals. 【2. Oxygen Gas】 It has the property of supporting combustion and contributes to high-temperature combustion and the maintenance of life in organisms. Applications include steelmaking, which requires time reduction and environmental improvement, and aquaculture, which requires high-concentration oxygen water. 【3. Argon Gas】 It is an inert gas that makes up just under 1% of the air. Because it remains inert even at high temperatures, it is used as a filling gas in fluorescent lamps. In recent years, it has also been registered as a food additive, and it is becoming a gas of great interest, including its use as a filling gas for food.
