Filling machine is a kind of packaging equipment that many liquid production enterprises will use. There are also many types of filling machines on the market, and their application ranges are also spread across all walks of life. According to the filling principle, the filling machine can be divided into normal pressure filling machine, pressure filling machine, liquid filling machine, oil filling machine, paste filling machine, sauce filling machine, granular slurry filling machine , powder filling machine, vat water filling machine and vacuum filling machine.
The difference between different types of filling machines is also very large. For example, the normal pressure filling machine is filled by the weight of the liquid under atmospheric pressure. This type of filling machine can be divided into two types: timing filling and constant volume filling, which are only suitable for filling low-viscosity and gas-free liquids such as milk and wine. The pressure filling machine is filled at a pressure higher than atmospheric pressure, and 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 by its own weight. Filling is called equal pressure filling; the other is that the pressure in the liquid storage tank is higher than the pressure in the bottle, and the liquid flows into the bottle by the pressure difference. Most high-speed production lines use this method. The packaging machine pressure filling machine is suitable for filling liquids containing gas, such as beer, soda, champagne and other products.
Common vacuum filling machines are filled when the pressure in the bottle is lower than atmospheric pressure. Packaging machines are also packaging equipment used to package liquid products, such as beverage filling machines, dairy filling machines, viscous liquid food packaging machines, liquid cleaning products and personal care products packaging machines, etc., all belong to the scope of liquid packaging machines of.
