Negative pressure filling machine

[aminaas1576]

It can also be divided into two types: one is when the pressure in the liquid storage cylinder is equal to the pressure in the bottle, and the liquid flows into the bottle spontaneously under its own weight, which is called isobaric filling; the other is when the pressure in the liquid storage cylinder is higher than the pressure in the bottle, and the liquid flows into the bottle due to the pressure difference. This method is mostly used in high-speed production lines. The pressure filling machine is suitable for filling gas-containing liquids such as beer, soda, champagne, etc.


Negative pressure filling machine is used for filling when the pressure in the bottle is lower than the atmospheric pressure. This filling machine has simple structure, high efficiency and wide adaptability to the jamaica number data viscosity of the material, such as oil, syrup, fruit wine, etc., as shown in Figure 10.

2.4 Depending on the degree of automation
2.4.1 Manual filling machine

Small-sized filling machine, with the function of filling paste and liquid. It has the advantages of simple structure, convenient operation, economical and practical, accurate capacity, etc.

2.4.2 Semi-automatic filling machine

Semi-automatic liquid filling machine, in the process of filling liquid, the filling is automatic, mainly used for filling gas-containing liquids.

2.4.3 Fully automatic filling machine

Fully automatic filling machine. It can be divided into: single-machine automatic machine and combined automatic machine (which can include continuous cleaning, filling, seaming, gluing, packaging and other processes). Automatic filling is mostly realized by mechanical transmission.
