Nitrogen Generator for Food Preservation with Nitrogen Flushing

With the advancement of technology, people's demands for food preservation quality are increasingly higher. Controlled Atmosphere Storage (CAS) technology involves the use of inert gases such as nitrogen and carbon dioxide to inhibit bacterial growth and reproduction, slow down the metabolic processes of stored items, and maintain freshness. Compared to other preservation methods like temperature control, dehydration, preservative addition, and ionization radiation, CAS offers multiple advantages:

1. The use of inert gases to isolate air directly inhibits bacterial growth and reproduction, slows down the metabolic processes of food cells, and effectively extends the preservation period.

2. The temperature of the preserved food remains unchanged, and moisture is not lost, largely maintaining the food's original nutrition, texture, color, and taste.

3. CAS does not involve the addition of preservatives, acidification, temperature changes, or radiation. It is safe, environmentally friendly, pollution-free, simple, feasible, low in operational costs, and offers significant economic benefits.

4. Food packaged with gas is easy to transport, resists compression well, avoids breakage and adhesion, and maintains the appearance and shape of the food.

5. Nitrogen, as the primary method in CAS technology, has been widely used in various types of packaging and is favored by consumers. In food preservation, the requirement for nitrogen is not necessarily higher purity; a trace amount of oxygen in the surrounding gas can achieve better preservation results.

6. To meet the nitrogen requirements of the food industry, Lecheng has developed a specialized food nitrogen generation solution with adjustable purity ranging from 99.5% to 99.99%, based on the characteristics of the food industry. This solution achieves optimal preservation effects by accommodating different purity requirements for various foods. Equipment features:

7. Purity can be adjusted within the range of 99.5% to 99.99%. The nitrogen is dry with a low dew point, which is beneficial for food preservation.

8. Excellent cost-performance ratio and fast return on investment.

9. Simple and compact design with a small footprint, easy to clean, meeting the high cleanliness requirements of the food industry. The process is mature, manufactured with high-quality components, and durable.
