What is a rinsing machine
The bottling process is delicate, as the container must be sterile. For this reason, when the bottles are loaded directly on the line, the first machine they encounter, immediately before the filler, is the bottle rinsing machine.
The rinsing machine disinfects the inside of the bottles and makes them ready for filling. This process also removes any external residues that may have accidentally ended up inside the bottle, impurities, dust or foreign bodies.
How it works
Its operation is very simple. The bottles arrive in a row through a bottle-sized conveyor belt. From here they physically enter the machine through an auger (worm) which positions them at equal distance from each other.
Once inside the auger, the bottle advances until it is inserted into the star, which aligns the bottles. At this point the neck of the bottle is aligned immediately with a clamp that takes the bottle from the neck and turns it upside down.
A nozzle enters the mouth of the bottle and in a few moments a strong jet of peracetic acid, water or other disinfectant is nebulized at high pressure inside the bottle to remove foreign bodies. Then a strong jet of filtered compressed air is blown at high pressure to dry the bottle in an instant. Finally, the bottle is put back in position, ready to be moved to the filler.
Differences between the models
As with most of the machines in a bottling line, the rinsing machine also has different settings. For example, the height of the rotating head (which must adapt to the height of the bottle in use) where the pliers take the bottle, or the type of the auger and stars. These must all be made to measure the differences between the various types of bottle sizes or shapes, from a sparkling wine bottle to the typical narrow and long table wine bottle and from bottles from 250 cl to more than 2 liters. All parts of the machine have suitable stars and augers and different heights in addition to having more or less tongs and using different products for cleaning the bottles.
