The system is used for the production of carbonated beverage for 200ml to 2000ml PET bottling. To reduce the mineral content to a minimum degree through RO system, increase the dissolve speed of sugar and other additive material, to dissolve the CO2 gas into the beverage under the low temperature condition. To adopt series connection disks to make water layer thinner to increase the carbonating time of beverage, then use positive pressure filling machine to fill into bottle. Users can use different additive material to produce popular favor to meet the requirement of market.
