Operation of a bottle filling line
Products: water, fruit juices, oil, milk, sodas, sauces, syrups…
Bottle fillers or bottling units allow the filling and packaging of liquid, gaseous or non-gaseous, fluid and viscous products. Bottles can be filled semi-automatically (filling machine) or automatically (bottling unit).
A bottling line is composed of several steps in order to accomplish the automatic filling of several bottles per hour.
Composition of a line
The empty bottle can be purchased as a preform or already moulded. In the first case, the bottle is formed through the mould of the machine (extruder / bottle blower). The mould(s), as well as the adjustment system, can be changed in order to produce different bottle sizes. This is called bottle thermoforming.
In a second step, the bottles are filled using a volumetric dosing machine. The bottle is then closed and sealed with a capping machine. Finally, the bottles can be conveyed to a labelling station, or a tray packer or shrink-wrapper, to group the bottles and create packs.
Buying or selling a used bottling line
Buying a second-hand bottle filling machine remains a high investment for some companies. Prices vary depending on the condition, brand, location and year of manufacture of the machine.
Osertech offers a wide range of equipment and materials available, enabling buyers to find the best second-hand filling machine.
