There are several different types of bottle filling machines, each with their own unique features and capabilities. Some of the most common types of bottle filling machines as following listed types. Choose the proper type of Bottle Filler for your application according to the filling accuracy request:
1. Piston Filler: for all kind viscosity, especially for high viscosity. It is suitable for the demand of the same and precise volume filling.

Piston Filling Machines: These machines use a piston to fill bottles with liquid. The piston draws liquid from a holding tank and then dispenses it into the bottles.

2. Equal-Level Filler: Suitable for the demand for the constant level of container after filling. 

3. Pressure Overflow Filler: Suitable for the demand for a consistent visual filling level with high production capability is required.

Overflow Filling Machines: These machines fill bottles to a precise level by overflowing excess liquid. The bottles are placed under a nozzle, and the liquid is dispensed until it overflows and reaches a preset level.

4. Vacuum Filler: Suitable for the demand for a equal visual filling level is required.

Vacuum Filling Machines: These machines use a vacuum to fill bottles with liquid. The bottles are placed under a nozzle, and a vacuum is applied to draw the liquid into the bottles.

5. Time Gravity Filler: Suitable for high volume filling with low request on filling accuracy.

Gravity Filling Machines: These machines use gravity to fill bottles with liquid. The liquid is poured into a holding tank above the filling machine, and then flows into the bottles below.

6. Pump Filler (Rotary lobe Filler): Suitable for high viscosity liquid or liquid with solid or fiber which is required to fill intact such as popping boba pearls etc. without damaging the shape. .

7. Isobaric Filler (Counter Pressure Filler): For filling bottles or aluminum cans from a pressurized or non-pressurized bulk storage tank without losing carbonation.

Isobaric Filling Machines: These machines are used for filling carbonated beverages, and use counter-pressure to maintain the carbonation in the liquid. The bottles are pressurized with CO2 before the liquid is dispensed.

8. Flow Meter Filler: Suitable for low viscosity liquid filling with high request on filling accuracy and real-time shown the digit filling volume.

How to choose the bottle filling machine?

When choosing a bottle filling machine for a specific application and production capacity, there are several key factors to consider:

• Type of product: Different types of products require different filling methods, so it is important to choose a machine that is compatible with the product being filled.
• Production capacity: The production capacity of the machine should be able to meet the needs of the production line. It is important to consider factors such as the speed of the machine and the size of the holding tank.
• Bottle size and shape: The machine should be able to accommodate the size and shape of the bottles being filled.
• Accuracy: The machine should be able to fill bottles to a precise level, as this is important for maintaining product consistency and minimizing waste.
• Maintenance and ease of use: The machine should be easy to operate and maintain, as this will ensure that it runs smoothly and efficiently over time.

Overall, choosing the right bottle filling machine involves considering these key factors and selecting a machine that is best suited for the specific needs of the production line.

How to choose the different kind filling methods for filling different products?

Designing a total solution for filling different products by different filling methods requires a comprehensive understanding of the product and the filling process. Here is a general guide for filling different products by different filling methods:

• Gravity Filling Machines: Gravity filling machines are ideal for filling products that do not require precise filling accuracy, such as water, juices, and oils. The machine is typically equipped with a holding tank that is mounted above the filling head. The liquid is fed into the filling head and dispensed into the bottle by gravity.
• Piston Filling Machines: Piston filling machines are best suited for filling products that require a high level of accuracy, such as viscous liquids like sauces, creams, and pastes. The machine uses a piston to dispense a precise amount of product into the bottle. The piston is controlled by a timer, which ensures that each bottle is filled to the same level.
• Vacuum Filling Machines: Vacuum filling machines are ideal for filling products that are sensitive to air or that require a high level of precision, such as perfumes and essential oils. The machine uses a vacuum to draw the product into the bottle, which minimizes the amount of air that comes into contact with the product. This helps to preserve the quality of the product and ensure accuracy.
• Overflow Filling Machines: Overflow filling machines are best suited for filling products that require a precise level of filling, such as cosmetics and pharmaceuticals. The machine dispenses a precise amount of product into the bottle and then overflows the excess to ensure that the product is filled to the desired level.
• Isobaric Filling Machines: Isobaric filling machines are designed for filling carbonated beverages, such as soda and beer. The machine uses counter-pressure to maintain the carbonation in the liquid. The bottles are pressurized with CO2 before the liquid is dispensed. This ensures that the carbonation is maintained throughout the filling process.

In addition to choosing the right filling machine, it is also important to consider the entire filling line. This includes the conveyor system, bottle unscrambling machine,  bottle rinsing machine,  capping machine (cap sorting machine), labeling machine, and other components. The filling line should be designed to ensure that each component works together seamlessly to ensure maximum efficiency and accuracy.
