Differences Between Liquid Packaging Machines And Liquid Filling Machines

They differ in their overview. A liquid packaging machine is a packaging equipment used for packaging liquid products, while a liquid filling machine is a type of volumetric liquid filling machine mainly used for filling various oils, such as lubricating oil and edible oil.

They differ in their types. Liquid packaging machines are relatively fewer in variety and include tomato sauce automatic packaging machines, fully automatic liquid packaging machines, and liquid automatic packaging machines. They are primarily designed for automatic packaging of fluid and semi-fluid products such as juice, jam, honey, tomato sauce, shampoo, and liquid pesticides. The key components of these machines are made of stainless steel to ensure product hygiene and safety.

On the other hand, there are various types of liquid filling machines, categorized based on the filling principle into atmospheric pressure filling machines, pressure filling machines, and vacuum filling machines. These three types of filling machines have extensive applications. For example, atmospheric pressure filling machines rely on the weight of the liquid for filling under atmospheric pressure, pressure filling machines operate under pressure higher than atmospheric pressure, and vacuum filling machines fill the bottle under pressure lower than atmospheric pressure. Each type serves different purposes: atmospheric pressure filling machines are further divided into timed filling and volumetric filling, suitable for low-viscosity, non-gaseous liquids like milk and wine; pressure filling machines can be divided into two types, namely, equal pressure filling and pressure difference filling, with the latter often used in high-speed production lines for filling gaseous liquids such as beer, soda, and champagne; vacuum filling machines have a simple structure, high efficiency, and can adapt to a wide range of material viscosities, suitable for oils, syrups, fruit wines, etc.
