Liquid filling machine is mainly used for liquid filling of lotion, care liquid, oral liquid, disinfectant, eye wash, nutrient liquid, alcohol, injection, pesticide, medicine, perfume, edible oil, lubricant and special industries.

　　 liquid filling machine classification

　　 liquid filling machine can be divided into normal pressure filling machine, pressure filling machine and vacuum filling machine according to the filling principle.

　　 Atmospheric filling machine is filled by liquid weight under atmospheric pressure. This type of filling machine can be divided into two types: timing filling machine and constant volume filling machine. They are only suitable for filling low-viscosity and gas-free liquids such as milk and wine.

The pressure filling machine is used for filling at higher than atmospheric pressure. It can also be divided into two types: one is that the pressure in the liquid storage cylinder is equal to the pressure in the bottle, and the liquid flows into the bottle by 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 by pressure difference. This method is mostly 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 machine is to fill the bottle under the pressure lower than the atmospheric pressure. This type of filling machine has a simple structure, high efficiency, and a wide range of material viscosity adaptations, such as oils, syrups, fruit wines, etc.
