After the Pure Zhen production line at Mengniu Dairy's Baoding plant went into operation, the bottling air conditioning room was reduced in size, requiring the modification of the original supply and return air ducts. At the same time, new perforated plate outflow air outlets were added, and the roof supply air ducts were matched, adjusted, and reused. The return air will utilize the original downflow air ducts, which will be modified into return air.
