Types and applications of filling and capping equipment

Filling and capping equipment is widely used, such as in the field of food and beverage packaging, the filling and capping of beer, beverage, dairy products, liquor, wine, liquid spices, etc.; in the field of pharmaceutical, chemical and other products packaging, the filling and capping of detergents, cosmetics, water for injection, chemical reagents, chemical raw materials and petroleum products, etc.

The machine that automatically fills and seals liquid products into containers is called automatic filling and capping equipment, which is the key equipment of packaging production line. The containers for filling and capping include bottles, cans, tubes, etc. made of glass, metal, plastic and various composite materials.
Bottles and cans need special caps for sealing, and there are pressure type and rotary type according to the cap structure.

Filling and capping equipment is usually made into filling machine (single machine), filling and capping machine (two-in-one) and washing and filling and sealing (three-in-one) according to the requirements of the material to be filled, referred to as filling machine.

Production applications are usually classified in accordance with the following.
1.According to the container running route, there are linear moving filling and capping machines and rotary filling and capping machines.

2. According to the filling method, there are atmospheric pressure filling machine, equal pressure filling machine, vacuum (negative pressure) filling machine, mechanical pressure filling machine.

3. According to the different dosing devices, there are quantitative cup volume quantitative filling machine, liquid surface control quantitative filling machine, quantitative pump volume quantitative filling machine.

For example:

The filling machines used in soft drink factories, breweries and capping machines are rotary-type equal-pressure filling and capping machines, which usually control the liquid level of the container to achieve quantitative, while liquor factories use rotary-type atmospheric pressure filling and rolling capping machines. Most of the filling machines used in mineral water, juice and beverage factories, spices factories are rotary vacuum filling and capping machines; oil factories, jam factories, most of the filling machines used are mechanical pressure filling machines, usually liquid high-speed production can be rotary type, high-speed production, viscous high material with linear type.
