Beer equipment filling machine is based on the process of coiling filling, the working principle is: clean bottle enter into the beer equipment filling machine from the bottle belt, through the bottle star wheel sent to the rotary table on the bottle cylinder and increased. The bottle is fitted with a discharge port to form a seal. After the bottle is evacuated, the back pressure gas in the tank is flushed into the bottle. When the gas pressure in the bottle is equal to the gas pressure in the tank, the liquid valve opens under the action of the liquid valve spring.
At this time, beer enter into the glass bottle through the return pipe along the bottle wall, CO2 in the glass bottle through the return pipe is replaced back into the storage tank, when the wine rose to a certain height and the return air pipe block, automatically stop the wine. And then close the liquid valve and valve, drain the pressure of the bottleneck of the gas to avoid the gas in the glass bottle, so that complete the entire filling process.
