Filling machine manufacturers analyze filling methods commonly used in filling machines
Filling machine, although we don't see it often. However, our life cannot be separated from the filling machine. The bottled or canned beverages we usually drink are all canned by the filling machine. Do you know what filling methods are commonly used? Shandong trano filling machine manufacturer will take you to learn about it! 1. The pressure method uses mechanical pressure or air pressure to squeeze the filled materials into the packaging container. This method is mainly used for filling thick materials with high viscosity, for example, filling tomato sauce, minced meat, toothpaste, balsam, etc. The filling machine manufacturer thinks that the pressure valve can also be used for the filling of soft drinks such as soda sometimes. At this time, the pressure of the soda itself is directly poured into the bottle without inflation and equal pressure, thus improving the filling speed, the formed foam is easy to disappear because there is no colloid in soda water, which has certain influence on the filling quality. 2. Normal pressure method normal pressure method is also called pure gravity method, that is, under normal pressure, liquid material flows into the packaging container by its own weight. Most of the free-flowing materials without gas and liquid can be filled by this method, such as white wine, fruit wine, milk, soy sauce, vinegar, etc. 3. Isobaric method isobaric method is also called pressure gravity filling method, that is, under the condition of higher than atmospheric pressure, the packaging container is first inflated to form an air pressure equal to that in the liquid storage tank, then it flows into the packaging container by the weight of the liquid to be filled. This method is widely used in the filling of gas-containing beverages, such as beer, soda, sparkling wine, etc. Using this method to fill, can reduce the loss of CO2 contained in this kind of products, and can prevent excessive foaming in the filling process and affect the product quality and quantitative accuracy. 4. Vacuum method vacuum method is filled under the condition of lower than atmospheric pressure. Filling machine manufacturers think that vacuum method can be carried out in two ways :(1) The pressure difference vacuum type means that the liquid storage tank is under normal pressure, and only the air of the packaging container is pumped to form a vacuum. The liquid material flows by the pressure difference between the liquid storage tank and the container to be filled to complete the filling, this method is more commonly used in China. (2) Gravity vacuum type means that the liquid storage tank is in vacuum. The Packaging Container first pumps air to form a vacuum equal to that in the liquid storage tank, and then the liquid material flows into the packaging container by its own weight. Due to its complex structure, it is rarely used in China. Vacuum filling has a wide range of applications, which is suitable for filling liquid materials with slightly higher viscosity, such as oils and syrups. It is also suitable for filling liquid materials containing vitamins, such as vegetable juice, fruit juice, etc. The formation of vacuum in the bottle means reducing the contact between liquid materials and air and prolonging the shelf life of the product, the vacuum method is also suitable for filling toxic materials, such as pesticides, etc. , to reduce the overflow of toxic gases and improve working conditions. For general edible liquid materials such as bottled milk, bottled wine, carbonated drinks, etc. , equal pressure filling method, vacuum filling method, etc. can be adopted, but considering the cost, the isobaric filling method can effectively reduce the loss of CO2, maintain the quality of the gas-containing beverage, and prevent excessive foaming during filling, ensuring accurate filling measurement. These are several commonly used Filling methods for filling machines compiled by trano filling machine manufacturers. I hope you can have a deeper understanding of the filling machine through the description of this article. In addition, no matter what method is used for Canning, the taste of the drink cannot be poor, so we should clean the filling machine frequently to ensure the hygiene of the filling machine.
