In the food processing industry, oxygen supply with stable purity, low energy consumption and food-grade safety is a key factor to ensure product quality, processing efficiency and compliance with food safety standards. The psa oxygen generator (Pressure Swing Adsorption Oxygen Generator), as a specialized Industrial Oxygen Generator, relies on psa technology for oxygen generation to separate oxygen from ambient air through the selective adsorption of molecular sieves to nitrogen and other impurities. Compared with traditional oxygen supply methods such as bottled oxygen or liquid oxygen, it features ultra-low energy consumption, fast start-up, stable oxygen purity and no chemical additives, perfectly meeting the hygienic and efficiency requirements of food processing scenarios. This 15kW energy-saving psa oxygen gas generator is custom-designed for food processing, with optimized power consumption and purity control, making it an ideal choice for baking, fruit and vegetable preservation, aquatic product processing and other core links in the food industry.
psa technology for oxygen generation (Pressure Swing Adsorption Oxygen Generation Technology) has unique advantages in food processing compared with other oxygen generation technologies:
- Food safety: The whole process uses physical adsorption to separate oxygen, without adding any chemicals, and the oxygen produced has no peculiar smell or impurities, complying with the requirements of food contact safety;
- Energy efficiency: The vacuum regeneration link is optimized for small-output scenarios, and the 15kW frequency conversion design reduces power consumption by 20%-30% compared with traditional PSA technology, which is crucial for food processing enterprises with long operating hours;
- Stability: The dual adsorption tower design ensures continuous oxygen production, avoiding production interruptions caused by oxygen supply shortages in continuous processing lines such as baking and canned food production;
- Hygiene: The equipment’s internal pipeline adopts a smooth design without dead corners, which is easy to clean and disinfect, meeting the strict hygiene requirements of food processing workshops.
For food processing enterprises, cost control is directly related to profit margins, and the psa oxygen plant cost of the 15kW energy-saving model has obvious advantages:
- Initial investment: The psa oxygen generator price of this model is about $8,000-$12,000, which is 30%-40% lower than that of small-scale liquid oxygen vaporization equipment, and no additional storage and transportation costs are required (unlike bottled oxygen);
- Operating cost: Calculated based on 16 hours of daily operation and an average oxygen output of 10Nm³/h, the daily power consumption is only 60.8kWh. At an industrial electricity price of $0.12/kWh, the daily electricity cost is about $7.3, while the daily cost of bottled oxygen with the same oxygen volume is about $35, saving more than $9,500 annually;
- Maintenance cost: The food-grade molecular sieve has a service life of up to 5 years, with a replacement cost of about $1,500, and daily maintenance only requires cleaning the air filter (costing less than $50 per month), far lower than the maintenance cost of liquid oxygen storage tanks.
The psa system for oxygen of this 15kW PSA oxygen gas generator can be widely applied to multiple core links in food processing:
- Baking industry: 90%-92% oxygen is used for combustion-supporting of baking ovens, which can improve combustion efficiency by 20%, reduce fuel consumption by 15%, and make the baking temperature more uniform, avoiding uneven baking of bread, cakes and other products;
- Fruit and vegetable preservation: 93%-95% oxygen is mixed with nitrogen to form a modified atmosphere (MAP), which can extend the shelf life of fruits and vegetables by 2-3 times, reduce rot rate by more than 30%, and maintain the original taste and nutrition of products;
- Aquatic product processing: Oxygen aeration is used in the pre-processing of aquatic products (such as fish and shrimp), which can keep aquatic products alive for a longer time, reduce mortality during processing, and improve the quality of finished products;
- Canned food processing: Oxygen is used for oxygenation in the sterilization link, which can shorten the sterilization time, reduce nutrient loss of canned food, and ensure product safety and shelf life.
When selecting a psa oxygen generator manufacturers for food processing, enterprises must prioritize food-grade certification and industry experience:
- Certification compliance: Ensure that the equipment has passed FDA, HACCP and other food safety certifications, and the oxygen-contacting parts meet the requirements of food contact materials (such as FDA 21 CFR Part 177);
- Customization capability: Choose manufacturers that can customize oxygen purity, output and control systems according to different food processing links (e.g., baking vs. preservation);
- After-sales service: Ensure that the manufacturer has a professional after-sales team that can provide on-site installation, commissioning and maintenance services, and respond to equipment failures within 24 hours to avoid production interruptions;
- Case verification: Prioritize manufacturers with successful cases in the food processing industry (e.g., cooperation with baking factories, fruit and vegetable processing enterprises) to ensure equipment adaptability.
The 15kW energy-saving psa oxygen gas generator is a highly adaptable and cost-effective oxygen supply solution for the food processing industry, relying on mature psa technology for oxygen generation to meet the diverse oxygen demand of different processing links. Its food-grade design, low energy consumption and stable performance not only ensure compliance with food safety standards but also significantly reduce the operating costs of enterprises. For food processing enterprises, selecting such equipment that is tailored to the industry’s characteristics can not only improve processing efficiency and product quality but also enhance the core competitiveness of enterprises in the market. As the food industry continues to pursue high quality and low carbon, the pressure swing adsorption oxygen plant represented by this equipment will become an indispensable core equipment in the food processing industry.
