Pure bottle caps are sterile bottle caps, which are developed and produced in line with the production of pure draft beer in the domestic market in recent years. Pure draft beer maintains its taste and nutrition and is setting off a huge wave in the Chinese beer market. Due to the change of pasteurization to membrane filtration in the production process of draft beer, the draft beer requires filling machine pipes, glass bottles, crown caps, and filling room air to achieve aseptic filling. Standards, especially the brewer's control of the harmful bacteria in beer, have added a strict microbiological testing program to the crown cap—the only package whose suppliers control the sterility requirements.
For this reason, the production line for the production of sterile bottle caps using the high-heat, filter-sterilization method ensures that the aseptic caps produced are the green bottle caps that are most safe to use in the brewery.
Take the domestic pure bottle cap manufacturer as an example, Ziquan established a weekly inspection system for dust particles in the production line to ensure the safety of the production line and ensure the effectiveness of the aseptic caps, to ensure the cooling of the caps and the cleanliness of the packaging room. The sterilized condition of 10,000 grades is required to produce pure bottle caps; a professional microbiological testing room is established synchronously, and the total number of harmful bacteria and bacteria in beer is detected for each batch of caps, thereby ensuring the production of sterile caps. It is also the only microbial detection room in the domestic industry.
