1. There are several common types of canning machines in the market.
Common canning machines in the market can be divided into four categories according to packaging form, automation level, filling principle, and material type, as follows:
. Bagged liquid packaging machine: For flexible packaging such as foldable film bags and self-supporting bags, it supports integrated bag making, filling, and sealing. It is divided into three side sealing/four side sealing bagging machines, self-supporting bag filling machines, and prefabricated bag filling machines, suitable for laundry detergent, sauces, milk, and other products. Bucket liquid packaging machine: Suitable for large containers of 5L or more, such as 20L chemical drums and 10L edible oil drums. It often uses weighing or flow meter filling, with a capping mechanism, for large capacity packaging of industrial lubricants, bucket water, large barrels of sauce, etc. • Hose liquid packaging machine: for plastic hoses and aluminum-plastic composite hoses, it completes the filling, sealing, and coding processes, commonly used in the daily chemical and pharmaceutical paste industries.
2. Classified by automation level • Semi automatic liquid packaging machine: requires manual assistance for bottle/bag loading and positioning, the machine completes the core filling and sealing actions, has a simple structure and low cost, and is suitable for small batch production. • Fully automatic liquid packaging machine: It can achieve unmanned bottle sorting/bag making, filling, sealing, and finished product production processes, and can be connected to front-end and back-end production equipment. It has high production capacity and stable filling accuracy, and is sui

3. Classified by filling principle • Atmospheric pressure filling machine: It relies on atmospheric pressure and the weight of the liquid to complete filling, with a simple structure and fast speed, suitable for low viscosity airless liquids such as water, juice, and soy sauce. Negative pressure filling machine (vacuum filling machine): First, negative pressure is formed inside the container, and filling is completed with the help of pressure difference, which can avoid liquid foaming and is suitable for materials that are prone to oxidation and foaming, such as wine, essential oils, and cosmetic raw materials. Isobaric filling machine: First, fill the container with inert gas to make the pressure of the container and storage tank consistent, and then fill it by its own weight. It is designed specifically for gas containing liquids, such as carbonated beverages and beer. • Pressure filling machine: The liquid is filled by external force, suitable for high viscosity materials such as tomato sauce, honey, laundry detergent, cream, etc.
4. Classified by material type • Paste filling machine: Suitable for paste like materials such as toothpaste, ointment, cosmetic cream, etc. Powder filling machine: used for quantitative filling of powdered and small granular materials in industries such as chemical, food, and agricultural products. Particle filling machine: suitable for filling granular materials in industries such as pharmaceuticals, daily chemical products, food, pesticides, etc.
2. Which type of flowmeter is better for beverage filling production lines and why?
In the front-end formulation stage of the beverage filling industry, sanitary electromagnetic
