Today, with the continuous development of science and technology, filling machines have been widely developed in all walks of life. Liquid filling machines are industrial machinery and equipment used to fill liquids, and because liquid filling encompasses a wide range, there are, according to different classification standards, different types of liquid filling machines. The use of mechanized filling can not only improve labor productivity, reduce the loss of products and ensure the quality of packaging, but also reduce the production environment and the mutual pollution of the material being filled. Therefore, modern liquor production industries generally use mechanised filling machines.

　　Filling machine knowledge classification: different filling materials (gas-containing liquid, non-gas-containing liquid, paste, etc.) and different packaging containers (bottles, cans, boxes, barrels, bags, etc.), the use of filling machine varieties are not the same, usually filling machine classification methods are as follows.

　　Classification of filling machines.

　　1、according to the degree of automation: manual filling machine, semi-automatic filling machine, automatic filling machine, filling and capping joint machine

　　2、according to the structure: linear filling machine, spiral filling machine

　　3、According to the dosing device: cup filling machine, liquid surface filling machine, rotor filling machine, plunger filling machine

　　4、According to the number of filling valve head: single-head filling machine, multi-head filling machine

　　5、According to the filling principle: vacuum filling machine, atmospheric pressure filling machine, counter-pressure filling machine, negative pressure filling machine, pressurized filling machine.

　　6、According to the structure of the feeding cylinder: single chamber feeding filling machine, double chamber feeding filling machine, multi-chamber feeding filling machine

　　7、according to the packaging container lifting structure: chute type lifting filling machine, pneumatic lifting filling machine, chute pneumatic combination lifting filling machine

　　Reasonable choice of filling machine is an important way to ensure product quality and improve economic efficiency. In general, should be closely linked to the actual production, try to choose good quality, high efficiency, simple structure, easy to use and maintain, small size, light weight filling machine.
