The working process of a vacuum filling machine is as follows:
Bottle Loading Stage
After empty bottles are packed in crates, they are transported by conveyor to a depalletizer. The pallets are unloaded one by one, and the empty bottles then enter an uncaser. The empty crates pass through a crate washer for thorough cleaning and are then sent to the caser side, ready to receive filled bottles.
Sterilization and Cleaning
The empty bottles from the uncaser enter a bottle washer for disinfection and cleaning. After passing through a bottle inspection machine, only bottles that meet cleanliness standards proceed to the filling stage.
Filling and Capping
Qualified bottles are filled with beverage by the filling machine. A capping machine then applies caps and seals the bottles to prevent leakage. Depending on the characteristics of the beverage, different types of fillers and cappers may be selected. Components such as filling valves and capping heads in this section operate under continuous contact with the product and require high precision, corrosion resistance, and wear resistance. Hansheng Automation provides custom machining of these parts according to customer drawings or samples.
Labeling
After capping, the bottles enter a labeling machine, where labels are accurately applied. Finally, the labeled bottles go to a caser for packing and are then sent to a palletizer for storage in the warehouse.
It is worth noting that although the basic process is similar, specific types of beverages, such as beer, may require dedicated filling machines and crown capping machines. A sterilization step may also be added to meet particular processing requirements. The selection of capping machines is adjusted according to the cap type, such as crown caps, screw caps, or plug seals.
