Nowadays, filling machine for liquid is used for both carbonated and non-carbonated soft drinks. These drink filling machines are designed in a manner that they keep away the dirt and bacteria. The working principle of carbonated soft drink filling machine is easy to understand.
The carbonated soft drink pours down from the filler tank into the bottle. In the meantime, air from the soft drink bottle is eliminated with the help of an air tube. Once the level of soft drink in the bottle arrives at the nozzle opening of an air tube, the filling is terminated.
Two filling methods are quite common in the drink filling industry, one is overpressure level filling and the second is non-pressurized level filling. Let’s have a look at these methods in detail.
It’s possible to fill PET and glass bottles with carbonated soft drinks and beverages. The overpressure level filling method makes possible the bottling of carbonated drinks without releasing CO2 from the drink. The filling is done under an N2 or CO2 controlled environment which guarantees the preservation of high-quality carbonated soft drinks.
The working principle of glass bottle filling is quite simple. First, the carbonated soft drink runs into the glass bottle from the filler tank. All the air inside the glass bottle is removed via an air tube. The filling of the bottle is stopped when the drink reaches the bottleneck. The filling machine for liquid also prevents the release of carbon dioxide to ensure quality carbonated soft drink.
Bottle filling machine for sale is designed in a manner that it can fill both PET and glass bottles on a single machine. The working principle of PET bottle filling is the same as the glass bottle.
This method involves both single-chamber and double-chamber filling. Under a single-chamber filling, light under-pressure or atmospheric pressure is maintained on the top of carbonated soft drink in the filler tank. Here the filler tank comprises two separate chambers, one chamber is filled with soft drink whereas the other is filled with air that is removed from the PET or glass bottles. Bottle filling machine price depends on its capacity and quality.
· The bottle is pressurized and then carbonated soft drink pours to a valve through a tube. The valve incorporates an inductive flowmeter to scan the flow of drink and passes on the impulses to the control system.
· Once the quantity of impulses is recorded, the flowmeter shuts the filling valve.
· Soft drink fills into the bottle alongside the walls and air is extracted out from the bottle at the same time.
