The difference between liquid packaging machine and liquid filling machine

This article aims to introduce the difference between a liquid filling machine and a liquid packaging machine, so that you can distinguish these two types of machinery.


Nowadays, many customers don't know much about liquid packaging machines and liquid filling machines, and they all think that their functions are the same. In fact, they are different. What is the difference between them? Next, Beiltmachinery, a professional filling machine manufacturer, will answer you, hoping to help you better distinguish between the two.

Scope of application of liquid packaging machine and liquid filling machine

First of all, their scope of application is different. Liquid packaging machines are packaging equipment for packaging liquid products, while liquid filling machines are quantitative liquid filling machines, which are mainly suitable for filling various oils, such as lubricating oil and edible oil.

Types of Liquid Packaging Machines and Liquid Filling Machines

Secondly, their types are different, and there are fewer liquid packaging machines: ketchup automatic packaging machine, automatic liquid packaging machine, and liquid automatic packaging machine, they are mainly for fluid and semi-fluid products such as juice, jam, honey, tomato Sauce, shampoo, liquid pesticides, and other products are automatically packaged, and the process parts are made of stainless steel, which can well ensure the hygiene and safety of the products.

There are many types of liquid filling machines. According to the filling principle, they can be divided into atmospheric filling machines, pressure filling machines, and vacuum filling machines. These three filling machines are widely used. For example, atmospheric pressure filling machine fills by the weight of liquid under atmospheric pressure, a pressure filling machine fills under atmospheric pressure, and a vacuum filling machine fills under the pressure in the bottle is lower than atmospheric pressure filling.

Liquid filling machine

The functions of the three are different. The atmospheric filling machine is divided into two types: timed filling and constant volume filling. It is only suitable for filling low-viscosity and gas-free liquids such as milk, wine, etc.; pressure filling machines are also It can be divided into two types: one is isobaric filling, and 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. Liquid filling of gas, such as beer, soda, champagne, etc.; vacuum filling machine has a simple structure, high efficiency, and a wide range of adaptability to the viscosity of materials, such as oil, syrup, fruit wine, etc.

Principle features of liquid packaging machine and liquid filling machine

Furthermore, their principles and characteristics are different. Liquid packaging machines are generally made of stainless steel, quantitatively filled by high-level balance tanks or self-priming pumps, directly heat-sealed and cut, and the bag size, packaging weight, and sealing and cutting temperature can be easily and reliably adjusted. The operation process is simple, the accuracy error is small, and it is very convenient for installation adjustment, equipment cleaning, maintenance, etc. Some machines use anti-drip and wire drawing filling heads, anti-high-foaming product filling, and lifting systems, to ensure the positioning of the bottle mouth positioning system and liquid level control system.

It can be seen from this that there are many differences between the liquid packaging machine and the liquid filling machine, not only in their principles, and functions but also in terms of use. product equipment.

Through the introduction of the above content, I believe that everyone has some understanding of liquid filling machines and liquid packaging machines. For more information about filling machines, you can go to our official website to view, or click the link below to view:
