PSA Nitrogen Generator Winery

Shenger Gas PSA nitrogen generator winery series is an efficient and energy-saving on-site nitrogen generation equipment. It eliminates reliance on traditional bottled nitrogen or liquid nitrogen and converts inexhaustible air into nitrogen of the required purity directly at your winery. This "on-demand" model not only significantly reduces operating costs, but also ensures the absolute timeliness and safety of gas supply. It is an indispensable core equipment for a modern and intelligent winery.

Working principle: pressure swing adsorption technology

The core principle of this series of PSA nitrogen generator winery is mature pressure swing adsorption technology. Air contains approximately 78% nitrogen and 21% oxygen. We utilize the difference in the adsorption rates of oxygen and nitrogen by carbon molecular sieves to achieve efficient separation of the two.

1. Adsorption stage: After precise filtration and drying, the compressed air enters the adsorption tower filled with carbon molecular sieves. The carbon molecular sieve will preferentially and quickly absorb oxygen, moisture and carbon dioxide, allowing high-purity nitrogen to flow out from the top of the tower for production use.

2. Decompression and regeneration stage: When a single adsorption tower is close to saturation, the system will automatically switch to another adsorption tower to continue working. At the same time, the saturated tower will be quickly decompressed to desorb and empty the adsorbed impurity gas, thereby realizing the regeneration of the carbon molecular sieve.

3. Cycle alternation: The two adsorption towers are controlled by intelligent programs to cycle adsorption and regeneration to ensure continuous and stable output of nitrogen.

Product core advantages

• Economical and efficient: one-time investment, long-term benefits, and extremely low operating costs.
• Flexible purity: the required purity can be accurately set and stably output according to different process stages.
• Ready-to-use: no storage required, stable supply, completely bid farewell to the risk of "gas outage".
• Intelligent control: fully automatic operation, clear status at a glance, simple operation and convenient maintenance.
• Long-life design: The core carbon molecular sieve has a long service life and the entire machine structure is sturdy and durable.
• Tailor-made: Shenger Gas provides one-stop service from solution design, equipment customization to installation and commissioning.

Industrial applications in winemaking

PSA nitrogen generator winery equipment provides protection for the entire process of wine production:

• Grape crushing and pressing: Nitrogen protection to prevent oxidative browning of grape juice.
• Fermentation process: A nitrogen protective layer is formed on the top of the fermentation tank to isolate oxygen.
• Aging and storage: used to fill the top space of storage tanks to prevent wine from aging and deteriorating.
• Tank dumping and blending: Use nitrogen to drive out oxygen when pipes and tanks are switched.
• Before bottling: replace empty bottles with nitrogen and inject nitrogen above the wine to replace expensive inert gases.

Certifications and standards

Shenger Gas always adheres to the highest quality and safety standards. During the design, manufacturing and testing process of our PSA nitrogen generator, we strictly follow international and domestic authoritative standards to ensure the reliability and safety of each piece of equipment.
