Compressors supply pure, oil-free air to nutritional supplement manufacturer
Kingdomway Group, a provider of nutritional supplements, operates four production facilities in Xiamen and Hohhot, Mongolia.
“Fermentation is one of the most important steps in producing our key additives, including coenzyme Q10, DHA, and ARA for milk and nutritious health products. As the compressed air comes into direct contact with the fermentation process, air purity is vital. The presence of even small oil traces will kill the bacteria, contaminate the end product and put consumers’ health at risk. Therefore, absolute oil-free compressed air is our focus,” said Mr Jiang, Site Manager at Hohhot.
To meet their compressed air requirements during the fermentation process, Atlas Copco recommended ZA 6G-300 low-pressure, oil-free screw compressors to keep the Hohhot production line running smoothly.
“As there are 16 fermentation tanks connected to the production line, the pre-filter, moisture separators and other equipment may cause drops in pressure and air loss,” said Leo Yang, Senior Sales Engineer with Atlas Copco. “To maintain the incoming air pressure in the fermentation tank at 2-2.5 bar - and taking into consideration other production processes and conditions - we set the front-end input pressure at 3 bar to keep the fermentation production line running stably.”
Atlas Copco ZA compressors have received ISO 8573-1 Class 0 (2010) certification for 100% air purity. The compressors incorporate stainless steel coolers, AGMA A4/DIN 5 gears, and an integrated variable-speed electrical drive system, which the company says offers energy savings of up to 35%.
