What is the principle of filling machine? For different filling machines, their working principles are different. The following is an introduction to several common filling methods.
what is the principle of filling machine 
1. Atmospheric filling machine
The filling is carried out by the weight of the liquid under atmospheric pressure. This type of machine is divided into two types: timing filling and constant volume filling, which are suitable for filling low-viscosity liquids without gas. Such as milk, mineral water, etc.
2. Pressure filling machine
It is filled at higher than atmospheric pressure. 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, which is called equal pressure 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 the pressure difference. This method is often used in high-speed production lines. Suitable for filling liquids containing gas, such as beer, soda, etc.
3. Vacuum filling machine
The pressure in the bottle is lower than atmospheric pressure for filling. This filling machine has a simple structure and high efficiency. It has a wide range of adaptability to the viscosity of the material, such as oil, syrup, etc. can be used.
4. Oil filling machine
It can be filled with various oils, such as edible oil, lubricating oil, peanut oil, soybean oil, etc. This type of filling machine is a filling machine specially developed for oil materials, which can realize flexible configuration of manual operation and unmanned operation. According to the measurement method, it can be divided into flowmeter type, piston type, weighing type and so on. According to the equipment style, it can be divided into linear type and rotary type.
According to different filling machine types and filling materials, the following configurations can be selected:
A. Needle filling head: Suitable for filling small-caliber bottles and tube packaging products. The diameter and length of the needle part can be customized according to the specific size of the container.
B. Turn/ball valve control system: It is suitable for materials with different viscosities and particles, and can solve various pressure problems caused by high-position and high-pressure feeding.
C. Hopper: It is recommended to configure when filling products with higher viscosity to achieve better filling results.
