In our daily life, we can see many packaged liquids, such as chili oil, edible oil, fruit juice, etc., which are very convenient for us to use. Today, with the rapid development of automation technology, most of these liquid packaging methods use automatic packaging technology. Let's talk about the classification of liquid packaging machines and their working principles.
According to the filling principle, it can be divided into atmospheric filling machine, pressure filling machine and vacuum filling machine.
Atmospheric filling machine is to fill the liquid according to its own weight under normal pressure. This type of filling machine is divided into two types: timing filling and constant volume filling. It is only suitable for filling low-viscosity, gas-free liquids, such as milk and wine.
Pressure filling machines are used for filling above atmospheric pressure. It can also be divided into two types : one is that the pressure in the liquid storage tank is equal to the pressure in the bottle, and the liquid flows into the bottle according to its own weight. Isobaric filling ; the other is that the pressure in the liquid storage cylinder is higher than the pressure in the bottle, and the liquid flows into the bottle through the pressure difference. This method is often used in high-speed production lines. The pressure filling machine is suitable for filling liquids containing gas, such as beer, soda, champagne, etc.
Vacuum filling machines are used to fill bottles under pressure below atmospheric pressure ; liquid packaging machines are packaging equipment for packaging liquid products, such as beverage filling machines, dairy products filling machines, viscous liquid food packaging machines, liquids Cleaning products and personal care products packaging machines, etc., belong to the category of liquid packaging machines.
Due to the abundant liquid products, there are many types and forms of liquid product packaging machines. Among them, liquid packaging machines for packaging liquid food have higher technical requirements. Sterility and hygiene are the basic requirements of liquid food packaging machines.
