Nitrogen is a basic environmental substance. It is a colorless, odorless and chemically inert gas, accounting for 79% of the earth's atmosphere. Gaseous nitrogen does not leave any chemical residues when used in the preservation process. It is a common understanding for the manufacturers of beer, wine and fruit juice to use nitrogen to keep fresh. It can make such products more authentic, longer shelf life, and more suitable for the taste of modern consumers. Many beer, wine and juice makers still use carbon dioxide as a fresh-preserving gas. Generally speaking, a brewery with an average annual output of 100,000 tons needs to be equipped with carbon dioxide recovery equipment of 1000 kg/hour, with an investment of about 6 million yuan. But beer production has off-peak season, off-season fermentation is reduced, carbon dioxide production sharply reduced, a lot of carbon dioxide recovery equipment can not start or can not meet the demand. And the fermentation of carbon dioxide to recycle washing, and then compressed purification, liquefaction, and finally vaporization use, energy consumption, cumbersome operation, complex equipment. After the advent of nitrogen preservation technology, compared with carbon dioxide, nitrogen production mechanism has many advantages.
1, with inexhaustible air as raw material, using pressure swing adsorption method to separate nitrogen from the air, low cost is incomparable to carbon dioxide recovery device;
2. The gas production speed is fast, and it can be used whenever it is opened. It can produce qualified nitrogen in about 20 minutes after starting up, and the stability is good, and it is not affected by the low season;
3, high degree of automation, using Siemens computer program control, no special care, and small footprint;
4, one-time investment, simple maintenance. Therefore, it is economical and practical to use nitrogen as an anti-oxygen gas in the production process of beer, wine and fruit juice drinks.
