18000 CPH 250ml / 330ml /500ML Aluminum can carbonated drinks Filling Sealing Machine production Line

Isobaric filling machines generally maintain a certain filling pressure in the storage box. When the container to be filled enters the filling machine, the container is first inflated. The gas can be compressed air or carbon dioxide gas. When the pressure in the container is the same as the pressure in the storage tank, the self weight of the feed liquid is filled through the open filling valve. During the filling process, the gas in the container should be smoothly exported and returned to the storage tank or gas chamber. In the filling of soft drinks, small champagne, and beer, isobaric filling is often used, and the workflow is as follows:
(1) The initial position of the bottle has not yet contacted the filling valve, and all gas-liquid channels are closed.
(2) The inflation pressure bottle and the filling valve cover rise to a predetermined position together, the rotary fork opens the inflation valve, and the pressure gas enters the bottle from the annular storage tank through the inflation channel.
(3) When the pressure in the bottle reaches the pressure of the storage tank, the liquid valve automatically opens, and the liquid must flow down the bottle wall through a diverter umbrella. When the liquid level in the bottle reaches the lower port of the return pipe, the liquid injection is completed.
(4) Close the valve rotary fork to close the pressure gas valve and the liquid valve.
(5) Inflation Open the top carbon dioxide filling valve to charge carbon dioxide or other inert gases from the annular groove into the bottle, driving away the air at the bottleneck.
(6) The pressure relief valve opens, and the pressure in the bottle escapes to the annular groove through the needle valve in the pressure relief channel.
