PET bottle fresh beer filling and capping machine manufacture in China

Machine Description:

Beer is a fermented drink, because the beer dissolved a large amount of carbon dioxide gas, very easy to produce foam, and beer needs to minimize contact with oxygen to ensure its flavor. two technical requirements that must be met in the filling production process.

1 Minimize contact between beer and oxygen: Usually the filling process of glass bottle is to realize oxygen replacement by 2 times vacuum, vacuum the bottle before filling, then inject carbon dioxide gas to replace oxygen, because the carbon dioxide is more heavy then Oxygen, the remaining oxygen is extracted when vacuuming again.

For easy open cans filling, it is not possible to replace oxygen with a vacuum due to the characteristics of the packing material, so in order to minimize oxygen contact, it is common to use a direct purge replacement to fill the cans with carbon dioxide gas before sealing with the filling valve. Due to the special design of the valve body, when the cans are sealed with the valve body, it continues to inflate the CO2 gas, while another gas loop releases a portion of the gas directly and it relies on a large flow of carbon dioxide gas to replace oxygen, while increasing the loss of carbon dioxide, but it is the only reliable solution to the current filling technology.

Beer filling process is the most complex technology, according to its product characteristics, the requirements for filling machinery is extremely high; usually beer filling process mainly has 10 steps:

1 Bottles infeed : Cleaned glass bottles comes into the filling machine through a conveyor belt and bottle screw sepater

2 Vacuum:Pre-vacuum the glass bottle for the purpose of replacing the oxygen in the bottle with CO2

3 Inflating: injecting carbon dioxide gas into the bottle

4 Vacuum again:Vacuum the remaining oxygen in the bottle again

5 pressure balance: Fill the bottle with carbon dioxide gas again and balance the pressure inside the bottle with the pressure inside the tank

6 Filling: because of the pressure in the bottle is balanced with the pressure of the filling tank, forming equal pressure, the filling valve was opened under the action of spring automatically , at this time the beer flows into the bottle under the action of gravity, and the gas in the bottle enters the tank through the gas return tube of the filling valve

7, Closing valve: when the liquid level reaches the position of the exhaust hole of the gas return tube, because the liquid has closed the gas return tube, it can not continue to discharge the gas, and the liquid can not continue filling, the bottle has been filled, the filling is finished, and close the filling valve.

8, Exhaust pressure : the bottle at the end of filling before leaving the filling valve, the filling valve exhaust will slowly release the pressure inside the bottle.

9, Bubble: After the filled bottle is removed out from the filling valve, a high pressure water drops inject in bottle to creat foam (usually hot water is used), a certain amount of foam is produced in the bottle, and the oxygen in the bottle mouth space is discharged

10,Capping: the last step is Capping, after capping and sealing, the bottle filling process is finished, the bottles come to pasteurizing process.
