For many users, there are certain misunderstandings in the understanding of the liquid packaging machine and the liquid filling machine. Many people think that the liquid packaging machine and the liquid filling machine are the same thing, but the name is different. This understanding is very wrong. There is a big difference between the liquid packaging machine and the liquid filling machine in essence. Here is the Wenzhou Zungwan Intelligent Machine Company to introduce the difference between the liquid packaging machine and the liquid filling machine. The difference:
Packaging machine is a general term for products produced and outsourced. There are many types of packaging machines and many classification methods. From different perspectives, there are many types. According to the product status, there are liquid, block, and bulk packaging machines; liquid packaging machines are packaging equipment for packaging liquid products, such as beverage filling machines, dairy filling machines, and adhesives. Thick liquid food packaging machines, liquid cleaning products and personal care products packaging machines, etc. 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, liquid packaging machines used to pack liquid food have higher technical requirements. Aseptic, hygienic and safe are the basic requirements of liquid food packaging machines.
Liquid filling machine is mainly used for liquid filling of lotion, care liquid, oral liquid, disinfectant, eyewash, nutrient liquid, alcohol, injection, pesticide, medicine, perfume, edible oil, lubricant and special industries.
Liquid filling machines can be divided into atmospheric filling machines, pressure filling machines and vacuum filling machines according to the filling principle.
Atmospheric filling machine is filled by liquid's own weight under atmospheric pressure. 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 higher than atmospheric pressure. 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 flows into the bottle by its own weight. Isobaric 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 pressure difference. This method is often used in high-speed production lines. The pressure filling machine is suitable for filling liquids containing gas, such as beer, soda, champagne, etc.
