The quality of compressed air, the main raw material quality of the nitrogen machine, is generally only matched with the world's three major brands of air compressors: American Shouli air compressor, air compressor, Atlas, Ingersoll Rand compressor, because the compressed air required for the nitrogen machine: Compressed air oil content must be less than 0.003ppm, compressed air outlet pressure must be controlled at 0.75MPa to 1.2MPa, compressed air from the air compressor system pressure loss process to manufacture nitrogen machine system, so our air compressor generally support 0.8MPa, because the working principle of nitrogen machine is pressure shift adsorption, So the pressure of the air compressor is very important, which determines the quality of nitrogen, but it does not mean that the greater the pressure, the better, to 1.2MPa pressure, will lead to molecular sieve crushing, so it must be less than 1.2MPa, usually the best choice for screw air compressors, piston compressor outlet temperature is high, high oil content, Directly affect the service life of our nitrogen machine air treatment equipment, and the replacement of the filter element is relatively frequent, three oil import brands imported air compressor control is generally less than 3ppm, the domestic air compressor oil content is high, the export temperature is high, the service life of the molecular sieve nitrogen machine is greatly reduced, the market price of the nitrogen machine imported molecular sieve is generally 150 yuan per kilogram, Taking into account the maintenance cost and price ratio, it is the best choice to use imported screw machines in air compressors, but small cubic nitrogen machines, you can choose domestic air compressors. Nitrogen purification is based on the palladium catalyst does not need to activate the characteristics, the use of hydrogenation catalytic performance of oxygen nitrogen machine to remove nitrogen, hydrogen workflow is through the flow meter into the pipeline, combined with raw material nitrogen into the deaerator, and then fully combined with the palladium catalyst, through the water vapor generated from the deaerator a large amount of nitrogen, the last step cooling. Using 5A molecular sieve adsorption to remove nitrogen in water, nitrogen outlet valve output nitrogen machine pure nitrogen.

     In addition to the sampling valve on the pipeline of the nitrogen purification unit, it can be connected to the micro-oxygen analyzer and micro-water detector. Nitrogen is the material basis, it is a colorless and odorless inert gas, chemically inert, accounting for 79% of the Earth's atmosphere, gaseous nitrogen used in preservation technology will not leave any chemical residues. The use of nitrogen production mechanism to produce nitrogen as wine, beer, juice beverage preservation is known that the current manufacturers of such products are facing a common. It can make the purification of this product more original flavor, long shelf life, more suitable for modern consumer tastes. To improve the quality of beer and the grade level of wine, the common problem is to improve its flavor stability. The internal quality of products and foreign brand-name products, the main difference is: high oxygen content in the storage process, easy oxidation, loss of freshness, aging. Beer, wine after fermentation with oxygen, during the canning process, oxygen is a harmful substance and is the source of many problems, "aging taste" and "deposit". Many domestic and foreign beer with nitrogen equipment, wine manufacturers use nitrogen oxygen discharge, that is, after fermentation, more than 98% of the purity of nitrogen, gas as filtration, transportation, pressure, such as in the production process of the wine tank, effectively avoid oxygen damage, which is an important link to improve the quality of beer.
