For many users, there are some misunderstandings about liquid packaging machines and liquid filling machines. Many people think that liquid packaging machines and liquid filling machines are the same thing, just called differently. This kind of understanding is very wrong. There is a big difference between liquid packaging machine and liquid filling machine in essence. Now let's introduce the difference between liquid packaging machine and liquid filling machine

Packaging machine is a general term for the machines for product production and outsourcing. There are many kinds of packaging machines and many classification methods. From different points of view, there are many kinds of packaging machines, including liquid, bulk and bulk packaging machines, according to product status; Liquid packaging machine is the packaging equipment for packaging liquid products, such as beverage filling machine, dairy filling machine, viscous liquid food packaging machine, liquid cleaning products and personal care products packaging machine, etc., all belong to the category of liquid packaging machine

Due to the rich variety of liquid products, there are also many kinds and forms of liquid product packaging machines. Among them, the liquid packaging machines used to package liquid food have higher technical requirements. Sterility, hygiene and safety are the basic requirements of liquid food packaging machines

 

liquid filling machine is mainly used for liquid filling of lotion, nursing liquid, oral liquid, disinfectant, eye wash, nutritional liquid, liquor, injection, pesticide, medicine, perfume, edible oil, lubricating oil and special industries

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

normal pressure filling machine is used to fill under atmospheric pressure by liquid weight. This type of filling machine can be divided into regular filling and constant volume filling. It is only suitable for filling low viscosity liquid without gas, such as milk, wine, etc.

Pressure filling machine is used to fill at a pressure higher than atmospheric pressure, which 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 filling is carried out by flowing the liquid 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. The pressure filling machine is suitable for filling liquid containing gas, such as beer, soda, champagne
