The Classification of Filling Machines

The filling machine is a device used for packaging various materials, and its classification methods are diverse. Here are some common classification methods:

1. Classification by Material Type:

• Liquid filling machine: suitable for filling liquid materials such as beverages, cosmetics, and chemical liquids.

• Paste filling machine: used for paste-like and creamy materials, such as ointments and skin care products.

• Powder filling machine: specifically for powdered materials, like food powders and medicine powders.

• Granule filling machine: suitable for granular materials, such as medicine granules and food granules.

2. Classification by Automation Level:

• Semi-automatic filling machine: requires manual intervention in some operations, such as placing containers and adjusting filling volumes.

• Fully automatic filling machine: achieves full automation, including container transportation, material filling, sealing, labeling, and other processes.

3. Classification by Working Principle:

• Atmospheric pressure filling machine: performs filling under atmospheric pressure, suitable for low-viscosity, non-gaseous liquids.

• Pressure filling machine: applies pressure to the material for filling through actuators such as cylinders or pneumatic-hydraulic pressure cylinders.

• Vacuum filling machine: performs filling under vacuum conditions, suitable for easily oxidized, volatile, or toxic liquids.

4. Classification by Equipment Structure:

• Linear filling machine: consists of a continuous production line with filling heads moving along a fixed track for filling.

• Rotary filling machine: comprises a rotating platform and one or more filling heads, with bottles rotated along the platform for filling.

• Multi-head filling machine: equipped with multiple filling heads, capable of filling multiple bottles simultaneously for high efficiency.

5. Classification by Usage Scenario:

• Benchtop filling machine: suitable for small-batch, high-precision filling needs in laboratories, research institutes, etc.

• Production line filling machine: specifically designed for large-scale production lines, featuring high speed, efficiency, and automation.

In addition, there are some specific types of filling machines, such as edible oil filling machines, thick sauce filling machines, etc., which are designed and optimized according to the characteristics and filling requirements of specific materials.
