But the terrible thing about plastic beer is that the beer is filled with carbon dioxide to replace the air and then filled. The residual air is almost not allowed, because it will cause serious aging of the wine in the beer bottle. There is a vacuum pipeline in each filling head, that is, vacuum first, then carbon dioxide, then wine, and finally a small section of hot water is needed to impact the wine when it is out of the bottle, so as to stir up foam and discharge the final residual air ;
So the difficulty is obvious. Will ordinary PET bottles be deflated during the vacuuming stage? It’s easy;
Furthermore, after the carbon dioxide is filled, there is a pressure of 0.66bar in the bottle. If the pressure is a glass bottle with a metal cap, this pressure is still acceptable, but there will still be a phenomenon of bottle bursting, and if it is a plastic bottle with a twist cap. , the possibility of bursting the bottle is higher, or the pressure of carbon dioxide will directly rush out of the bottle, then your bottle of beer will directly contact the outside world, and the cross-infection will not last long.
For beer manufacturers, they welcome PET bottles. After all, compared with the beer line, why is the failure rate of the beverage line lower, and the workshop environment and personnel operating safety so high? The main reason is that there are basically no PET bottles, no glass bottles (this is why Coke is replaced by glass for PET), online delivery, pouring, and pasteurization, there will be no glass fragments, and there will be no liquor left in the place. , there will not be a large amount of bacterial film attached to the surface of the equipment, and the maintenance and maintenance of the equipment is difficult – then it is super simple
