Filling machine application: Filling machine is usually one of the new products of packaging machinery and equipment, can be divided into liquid, paste, powder, particle filling machine, semi-automatic filling machine and automatic filling machine.
Working principle of filling machine:
Natural pressure filling
Natural pressure filling is also known as pure weight capacity method, that is, liquid under natural pressure with the help of weight into the product container. The vast majority are free to flow. This method can be filled with liquor, fruit wine, milk, soy sauce, vinegar and so on.
Isobaric filling
Isobaric method is also known as pressure heavy capacity filling method, that is, in the case of high atmospheric pressure, the packaging container is mainly inflated to form the same air pressure as the liquid storage tank, and then injected into the packaging container with the weight of the liquid filling material. This method is widely used to fill beer, soda water, soda wine and other gaseous beverages. This filling method can reduce the content of such products. CO loss in the filling process can prevent product quality and quantitative accuracy degree froth.
Vacuum filling
Vacuum filling is lower than atmospheric pressure, that is, the liquid storage tank is at normal pressure. Only the packaging container is pumped to form a vacuum. The liquid material depends on the space between the liquid storage tank and the container to be filled
This method is more commonly used in China for liquor and other products.
