The choice of machinery will depend on the specific requirements of your liquid product, production volume, and desired level of automation. When selecting a liquid bottle filling machine, it’s essential to consider factors such as the type of liquid, filling speed, accuracy, ease of operation, and maintenance requirements. Here are some common packaging machines used in the beverage industry:
Gravity filling machines rely on gravity to fill bottles with liquid, drawing from a time-based tank feed positioned above the filling head. . The product flows from a holding tank to the bottles due to gravity. This method is suitable for free-flowing liquids with the stable thickness without the need for extreme precision.
A pump liquid filler works by using a pump mechanism to draw liquid from a source, typically a drum or reservoir, and then dispenses that liquid into containers. Pump fillers are commonly found in industries where a moderate level of precision is acceptable, such as the food and beverage industry for filling sauces, dressings. To control the amount of liquid dispensed into each container, pump fillers typically use one of two methods:
Pulse Timing: This method involves counting the number of gear revolutions or pump strokes to determine the precise amount of liquid delivered into each container.
Time-Based Fill: In this method, the pump runs for a preset amount of time to fill the container. However, this method may be slightly less accurate than pulse timing.
The pump filler can be equipped with servo motors.
Piston fillers use a piston and cylinder to draw a precise volume of liquid from a reservoir and then dispense it into the bottles. This filling method is accurate and can handle a wide range of viscosities .Piston fillers are often used in industries that demand high accuracy, such as pharmaceuticals, cosmetics, and specialty chemical manufacturing, where precise fill volumes are critical. The machine can fully equipped with servo motors .
