Food Grade Carbon Dioxide Storage Tanks With Refrigerants Are Used in Carbonated Beverage Production Factories. The Carbon Dioxide Gas Is Compressed By A Compressor, Then Cooled By A Condenser, And Finally Expanded By An Expansion Valve To Achieve The Cooling Process. During The Filling Process, Carbon Dioxide Gas Is Cooled Through Refrigeration To Achieve A Low Temperature State For The Beverage During Filling
