Secondary pollution is a key hidden danger affecting water quality in barreled water production. Professional barreled water filling machines adopt full-process sterile control to eliminate pollution fundamentally.

1. Strict Pre-treatment of Barrels: Before filling, empty barrels go through high-pressure water flushing, food-grade disinfectant sterilization and sterile air drying to remove impurities and bacteria.

2. Sterile Filling Environment & Technology: The whole filling process is carried out in Class 10,000 clean workshops. All pipelines and filling nozzles are made of 304 stainless steel. Negative pressure sterile technology is adopted to prevent external air from entering barrels.

3. Double Guarantee of Sealing & Inspection: Precise capping ensures tight sealing without leakage. Weight testing and leakage detection are equipped to reject unqualified products. Full automatic operation reduces pollution caused by manual contact.
