What is the difference between food grade CO2 and industrial CO2
The differences are as follows:
First:different preparation methods
1, Food grade carbon dioxide: carbon dioxide produced in the alcohol fermentation process, after washing, impurity removal, pressure to make liquid carbon dioxide.
2, Industrial carbon dioxide: high temperature calcined limestone (or dolomite) in the process of carbon dioxide gas, after washing, impurity removal, compression, produced gas carbon dioxide:
Second, different uses
1, Food grade carbon dioxide: drinking drinks containing carbon dioxide, can make the body heat with carbon dioxide gas discharged. Creates a cool, refreshing feeling and stimulates the taste. Reducing PH has an antiseptic effect.
2, Industrial carbon dioxide: used as refrigerant, low temperature test of aircraft, missiles and electronic components, improve oil well recovery, rubber polishing and control chemical reaction, can also be used as fire extinguishing agent.
Third, the relevant regulations are different
1, Food grade carbon dioxide: liquid carbon dioxide for soda, gasoline and beverages, the maximum amount of use according to normal production needs. The concentration of carbon dioxide in food additives ranges from 98.8% to 99.8%.
2, Industrial carbon dioxide: bottled gas products in transportation, storage, use should be classified stacked, It is strictly forbidden to stack combustible gas and combustibles together,don’t near the open fire and heat sources, should be done not near the fire, do not touch oil and paraffin, do not explode, do not throw, do not impact, is strictly prohibited in the cylinder arc or arc, is strictly prohibited brutal loading and unloading.
