Many beverage production companies have newly launched production lines positioned as medium to high-speed beverage filling production lines ranging from 24000 to 36000 bottles per hour. Several domestic beverage packaging machinery manufacturers are already able to provide high-speed filling machines with a capacity of 36000 bottles per hour. However, in the past, rotary automatic blow molding machines with a capacity of over 18000 bottles per hour relied heavily on imports, and the high prices of imported high-speed blow molding machines have deterred many domestic beverage production enterprises from doing so.
　　
The PET bottle sorting machine, as the * equipment for medium and high-speed beverage filling production lines, is rapidly developing with the rapidly growing demand of China's beverage industry. In recent years, the connection between bottle blowing machines and filling machines through air ducts has become popular. Many domestic beverage production companies have adopted this method in their newly launched production lines, such as Nongfu Spring's drinking water and juice production lines, and Le Bais Xi'an and Fengrun factories' drinking water production lines. Although there are many advantages to using a blow molding machine connected to a filling machine through an air duct, for medium to high-speed beverage filling production lines, a bottle sorting machine becomes the *.
