Normal pressure filling
Normal pressure filling is also called pure gravity method, that is, under normal pressure, the liquid material flows into the product container by self weight. Most of them can flow freely. The liquid and non liquid materials can be filled with this method, such as Baijiu, fruit wine, milk, soy sauce, vinegar and so on.
Isobaric filling
Isobaric method is also known as pressure gravity filling method, that is, under the condition of higher than atmospheric pressure, first inflate the packaging container to form the same pressure as the liquid storage box, and then flow into the packaging container by relying on the self weight of the filling material. This method is widely used in the filling of aerated beverages, such as beer, soda and sparkling wine. This filling method can reduce the loss of CO2 in this kind of products and prevent excessive foaming in the filling process from affecting the product quality and quantitative accuracy
Vacuum filling
The vacuum method is filled under the condition of below atmospheric pressure, that is, the atmospheric pressure is in the liquid storage box, and only the vacuum is pumped out of the packing container, and the liquid material is filled by the pressure difference between the liquid storage tank and the container to be filled. The domestic method is often used for Baijiu and other products.
