Ever since Shanghai Yanzhong Beverage Co. Ltd. was founded in 1996, their salted soda water has been a favorite summer drink of Shanghai residents. In 2016 the company invested in a new manufacturing facility in the district of Boshan to meet an ever-increasing demand. Their aim was not only to scale up production, but to upgrade to a higher manufacturing standard, for increased safety, efficiency and energy savings.
Eliminating all risks of oil residues
In beverage production it is critical to eliminate all risk of oil residues polluting the product. If oil from the air compressor enters the PET water bottle, it can affect the taste and smell and at worst, be a health risk. Air power is needed for bottle blowing, filling, capping, labeling and packaging. Oil pollutants can block up the parts, creating unplanned downtime. What’s more, emissions from these parts can contaminate the workshop, which could also pollute the end product.
With all these risks in mind Atlas Copco was an easy choice for the purity of its 100% oil-free compressed air. Already back in 2008 Atlas Copco was the first supplier in the compressor industry to obtain the ISO 8573-1 class 0 oil-free air technology certificate.
Finding the best solution for the plant
A sales supervisor at Atlas Copco’s Oil-free Air division worked together with Zhang Lingfeng, Chairman of the Board of Yanzhong, to find the best solution for the new plant with regards to its manufacturing techniques, air demand and overall budget. An Atlas Copco ZDXtend integrated compressor now provides both low-pressure and high-pressure oil-free air for the production line. An ZR110FF unit provides medium pressure air for packaging and instruments, and an DX45 booster increases the medium pressure air to 40 bar to provide high-pressure air for bottle blowing. “So far, the machines are running very stably and smoothly, helping us achieve new sales records,” Zhang Lingfeng says.
