Carbonated Drink Filling Machine

Isobaric filling is also called pressure gravity filling. Inflate the bottle and make the air pressure in the bottle equal to the air pressure in the liquid storage tank, and then perform filling. First, let the CO2 in the upper layer of the liquid storage tank enter the bottle through the gas pipe, so that the pressure of the gas in the container to be filled is equal to the gas pressure on the liquid surface of the liquid storage tank. Then the gas-containing liquid material flows into the container to be filled by its own weight, and at the same time the gas in the bottle returns to the liquid storage tank through the gas pipe. When the liquid level rises to the orifice of the air pipe, the remaining air volume is in the bottleneck, and the air hydraulic force is constant, realizing the same height quantification of the liquid in the bottle. Open the exhaust valve, the remaining gas is discharged to the atmosphere, and the beverage in the trachea flows into the bottle, completing the entire filling process. The isobaric filling valve is not directly impacted during filling process, the CO2 has little loss and maintains a stable filling pressure. Isobaric filling method is suitable for filling carbonated beverages, beer, mineral water and sparkling wine.
