To get to the place of consumption, after rinsing and stabilizing, the beer in most cases should be bottled. Whatever the nature of the cylinder is, the same principle of bottling is used. It is necessary to provide a counter pressure higher than that of carbon dioxide in beer and a pressure equal to that of the cylinder container (tank) storage. This is achieved through application of the iso-barometric bottling and constancy of connecting pipe section to various machines. To prevent foaming, the temperature at the time of bottling beer should remain virtually constant, and the cylinders temperature needs to be not much different from the beer.
In terms of the importance during the process of cerveja de garrafa manufacturing technology, it should be noted that this stage requires the largest number of manpower and equipment. Technology, at this stage, is also the biggest source of infection and oxidation of the beer. Consequently, whatever the type of container is used, it requires preliminary a rigorous cleaning and sterilization so it should be ensured a high hygiene and, if possible, a corresponding sterility machinery, pipes, fittings and workrooms.
The most common bottling packages are the beer barrels and bottles. Before being switched to bottles and drums, filtered beer is usually stored in stainless steel tanks where the pressure is maintained to avoid loss of carbon dioxide. These tanks are placed in a special room located in the neighborhood of the filters and filling plants, and they act as a buffer tanks, compensating the differences that arise between filtering capacity and filling. In this way, filtering and filling both occurs still, flows smoothly, and the filtered beer can be analyzed again, especially regarding carbon dioxide content.
Filtered beer tanks that are also called “quiet” tanks are provided with level and graduated scale, so you can keep track of filtered beer, also the capacity of a tank must match production for 2-3 hours of filler. The capacity of all filtered beer tanks should provide 1-2 days of beer production.
The technological process of bottling machinery components is performed using the bottling line. They can be simple or complex. From a functional perspective, bottling lines can be semi-mechanized, semi-automated and automated.
All malfunctioning equipment related with bottling beer, usually starting from the introduction line of packaging empty cylinders from the store till finished product delivery in the bottled product to the store, are called the bottling line.
