Nitrogen Generator Application Case | Luohe Weilong Food Co., Ltd.

1. Customer Overview

Luohe Weilong Food Co., Ltd. is a leading modern leisure food manufacturing enterprise in China, specializing in the R&D, production and sales of seasoned flour products, konjac snacks and other popular casual food products. Adhering to strict food safety and standardized production systems, the company implements high-standard purification management throughout its food processing workshops. The food production process requires ultra-clean and inert production atmosphere to avoid product deterioration, ensuring food freshness, taste stability and long shelf life, which puts forward extremely high requirements on nitrogen gas purity and supply stability.

2. On-site Application

Our industrial PSA nitrogen generators are deployed in the customer’s standardized food processing workshops, dedicated to full-process atmosphere protection for food production, mixing, molding, packaging and finished product storage. With 99.99% high-purity nitrogen filling and isolation, the system effectively displaces oxygen and moisture in the production environment. It inhibits bacterial growth, prevents food oxidation, discoloration and flavor deterioration, maintains the original taste and freshness of leisure food, and significantly extends product shelf life while complying with food-grade production safety standards.

3. Project Technical Specifications

 Application Industry: Food processing & fresh-keeping protection

Required Nitrogen Purity: 99.99%

Stable Gas Supply Flow: 500 Nm³/h 

Operation Mode: 24-hour continuous stable gas supply

4. Project Cooperation Background

As Weilong Food continued to expand its automated production lines and upgrade food safety standards, the traditional gas supply method could no longer meet the stringent requirements of large-scale and standardized food production. Problems such as insufficient nitrogen purity, unstable gas output and high comprehensive operating costs posed hidden risks to food quality and shelf-life control. After strict supplier screening, technical comparison and on-site verification, the customer finally selected our food-grade high-purity nitrogen generation solution to support its standardized and intelligent food production system.

5. Operational Advantages & Project Benefits

High-purity and stable gas supply: The equipment stably delivers 99.99% high-purity nitrogen continuously, with constant pressure and stable flow rate. It fully adapts to the uninterrupted and high-volume production rhythm of modern food workshops, providing consistent inert atmosphere protection for food processing. 

Full-process food quality assurance: The oxygen-free nitrogen environment effectively suppresses oxidation reaction and microbial reproduction, preventing food rancidity, color fading and taste degradation. It greatly improves product consistency, reduces defective rates, and ensures safe and reliable food quality.

Food-grade safe & energy-saving operation: The whole set of equipment meets food production safety specifications, featuring fully automatic intelligent control, unattended operation, low energy consumption and minimal maintenance. It effectively reduces long-term operational costs for food factories and realizes green and efficient production.

Optimized shelf-life & market competitiveness: Stable nitrogen protection significantly prolongs the shelf life of finished products, reduces inventory loss and waste, and helps the enterprise maintain stable product quality in long-distance transportation and market circulation, further enhancing brand market competitiveness.
