For many users, there are certain misunderstandings in the understanding of liquid packaging machines and liquid filling machines. Many people think that liquid packaging machines and liquid filling machines are the same thing, but they are called differently. This kind of understanding is very wrong. There is a big difference between the liquid packaging machine and the liquid filling machine in essence. Let me introduce the difference between the liquid packaging machine and the liquid filling machine:
Packaging machine is a general term for product production and outsourcing machines. There are many types of packaging machines and many classification methods. From different points of view, there are many kinds, according to the product state, there are liquid, block, and granular packaging machines; liquid packaging machines are packaging equipment for packaging liquid products, such as beverage filling machines, dairy filling machines, sticky packaging machines, etc. Thick liquid food packaging machines, liquid cleaning supplies and personal care products packaging machines, etc. all belong to the category of liquid packaging machines.
Due to the rich variety of liquid products, there are also many types and forms of liquid product packaging machines. Among them, the liquid packaging machines used to pack liquid food have higher technical requirements. Sterility, hygiene and safety are the basic requirements of liquid food packaging machines. .
The liquid filling machine is mainly used for liquid filling of lotion, nursing solution, oral liquid, disinfectant, eye wash, nutrient solution, wine, injection, pesticide, medicine, perfume, edible oil, lubricating oil and special industries.
Liquid filling machines can be divided into normal pressure filling machines, pressure filling machines and vacuum filling machines according to the filling principle.
The normal pressure filling machine is filled under atmospheric pressure by the weight of the liquid. This type of filling machine is divided into two types: timing filling and constant volume filling, which are only suitable for filling low-viscosity and gas-free liquids such as milk and wine.
The pressure filling machine is used for filling at a pressure higher than the atmospheric pressure, and it can also be divided into two types: one is that the pressure in the liquid storage tank is equal to the pressure in the bottle, and the liquid is filled into the bottle by its own weight, which is called Isobaric filling; the other is that the pressure in the liquid storage tank 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 gas-containing liquids, such as beer, soda, champagne, etc.
