Food Production N2 Nitrogen Generator

Application in the food industry: nitrogen in the form of low temperature liquid and gas can be used for deep freezing, storage and packaging as a protective gas, and can also be used for filling drinks, high-quality crushing and controlling the maturity of fruit.

Many food raw materials need to be ground before processing. The heat generated during the process can melt its sensitive ingredients and hinder the grinding of the mill. For example, when grinding spices, absorbent food additives, sugar substitutes and lecithin, liquid nitrogen is injected into the grinder to protect valuable ingredients, which also increases the grinding output. Moreover, the inertia of N2 also prevents fire and dust explosion

In addition to the function of deoxygenation and quality preservation, the nitrogen-filled food packaging can effectively maintain the original color, flavor, shape and nutritional value of the food for a long time as long as it has the functions of pressure resistance, gas resistance and preservation

WORKING PRINCIPLE:
PSA technique (Pressure Swing Adsorption, PSA for short):it's a kind of advanced gas separation technology, based on physical adsorption of gas molecule on the internal surface of adsorbent (porous solid substances), using adsorbents in the same pressure easy to absorb the high boiling point gas, difficult to absorb low boiling point gas, and under high pressure adsorption amount of absorbed gas increases, under low pressure adsorption of absorbed gas to reduce the features to achieve gas separation. This process under pressure adsorption of impurities, under reduced pressure adsorption of impurities, make the adsorbent regeneration, is the PSA cycle.
