How to choose different types of filling machines

Filling machines can be of various types according to different classification criteria, as follows:

Ⅰ Classified by filling principle

1. Atmospheric filling machine: Filling is carried out by the self-weight of the liquid under atmospheric pressure. This type of filling machine divided into two types: fixed time filling and fixed volume filling. It is only suitable for filling low-viscosity liquids without gas, such as milk, liquor, mineral, etc.
2. Pressure filling machine: Filling is carried out under a pressure higher than atmospheric pressure. It can also be divided into two types: one is the pressure in the liquid storage cylinder is equal to the pressure in the bottle, and the liquid flows into the bottle by its own weight, which is called isobar 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 the pressure difference High-speed production lines often use this method, which is suitable for filling liquids containing gas, such as beer, soda, champagne, etc.
3. Vacuum filling machine Filling is carried out under a pressure lower than atmospheric pressure in the bottle. It has a simple structure, high efficiency, and a wide range of adaptability to viscosity of materials. It can be used for filling liquids such as oil, syrup, and fruit wine.

Ⅱ Classify by material type

1. Liquid filling machine: Equipment specially designed for filling liquid materials, with a brand new horizontal design, lightweight and convenient, automatic suction.
2. Paste filling machine: Used for filling paste-like materials, suitable for filling products with various viscosities from water-based to cream-based, it is ideal filling machine for daily chemical, pharmaceutical, food, and pesticide industries.
3. Oil filling machine: Can fill all kinds of oil products, such as edible oil lubricating oil, peanut oil, soybean oil, etc., filling machines specially developed for oil materials.
4. Sauce filling machine: Suitable for filling thick sauces with in condiments, such as chili sauce, broad bean paste, peanut butter, sesame paste, jam, beef tallow hotpot base, red oil hotpot base etc.
5. Granular slurry filling machine: Suitable for the pharmaceutical, daily chemical, food, pesticide, and special industries, it is an ideal filling equipment granular slurry viscous fluids.
6. Powder filling machine: Suitable for the quantitative filling of powdery and small granular materials in the chemical, food agricultural, and sideline product industries, such as pesticides, veterinary drugs, disinfectants, laundry powder, grain, seeds, milk powder, condiments, monos glutamate, salt, sugar, additives, etc.

Ⅲ Classify by degree of automation

1. Semi-automatic filling machine: requires manual participation in some of the operation process.

2. Fully automatic filling line: fully automated operation, high production.

Ⅳ Classified by filling range

1. Micro filling machine: suitable for filling small capacity containers, high precision, suitable for laboratory or small batch production.
2. Medium filling machine suitable for filling medium capacity containers, high efficiency, suitable for general production needs.
3. Large drum filling machine: suitable for filling large capacity drum materials, high efficiency suitable for large-scale production.

ⅤClassified by filling method

1. Straight line filling equipment: It is more common in the filling line and has a high market application and technical maturity.
2. Vertical liquid equipment: It has the function of manual and automatic switching, and the operation is flexible.
3. Vacuum filling equipment: It mainly targets the filling needs of some special, such as chemical products and pharmaceutical products.

In summary, there are many kinds of filling machines, and it is necessary to consider factors such as material characteristics, filling and production scale when choosing.
