There are not many filling machine manufacturers in Nanjing, such as Nanjing Yangzi Cereals, Oils and Foodstuffs Machinery Co., Ltd., but there are many kinds of filling machines. The well-known domestic filling machine manufacturers mainly include: Jiangsu Star A Packaging Machinery Group Co., Ltd., Jiangsu Meixing Beverage Machinery Co., Ltd., Guangzhou tech-long Packaging Machinery Co., Ltd., Jiangsu Xinmeixing Packaging Machinery Co., Ltd., Jiangsu Huayu Ling Fei Packaging Machinery Co., Ltd., and some manufacturers in Shandong and Zhejiang. The price of filling machine depends on filling speed, parts and control system. Generally, the price of a three-in-one machine with an output of 3,000 bottles per hour is around 250,000. I know that the above companies have been in business for a long time, and there are more detailed introductions in general trade publications, which is slightly more credible. I hope it helps you.
