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 bottling beer 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.

Brewing beer at home is a popular pastime for many people. Even in the UK where the public house culture is very strong, home brewing beer has a big following. Successive governments have increased the tax on buying beer in pubs and so many people have looked to save money by making beer at home.
There are both plus points and minus points to home brewing beer. The big advantage often cited by those who make beer at home is that they can select their own ingredients. The reason why this is an advantage is that people who brew beer at home can be sure they are using only good quality ingredients. For many people this means only using organically grown crops for the ingredients. By home brewing beer they can be sure that they will drink beer that does not contain any artificial chemicals or additives.
People who home brew beer generally are confident they will have a constant supply of beer, which is especially good for when guests unexpectedly arrive or a ball game is on the television. As the raw ingredients of beer are simple (they are just water, malt, yeast and hops), a home beer brewer can make beer in regular batches and store in the garden shed or outhouse. Lots of people find the very act of brewing beer a relaxing act and a stress reducer, even before they have tasted the fruits of their labour.
However, it is worth noting that home brewing beer is not for everyone. The first big disadvantage is that if you don’t brew your beer correctly you could end up with a concoction that tastes horrible; something that you would not be proud of serving up to your friends. Even if you know what you are doing, just one mistake could lead to a ruined batch of beer both in looks and taste.
A second negative for home brewing beer is that it takes a lot of time and effort. For most people it is much easier to pop into the supermarket on the way home from work and buy their beer than to wait for between thirty to thirty five days for a home brew. Beer making takes a long time; around ten to twelve hours for brewing and over a month for the beer to age.
Home beer making has become easier over the years. In the past at the very minimum it would have been necessary to mix the brew carefully, constantly check the gravity of the fermenting brew and then at precisely the right time transfer the brew into a barrel or bottles. However things have been simplified by the introduction of home brewing kits. In most cases these kits have a fermentation vessel that both looks and works like a barrel and this makes the entire process much easier to manage. The brewing and aging happen in this vessel. It just needs to be kept in a warm place for a few weeks and then when it is ready poor out directly. The risk of contaminates entering the brew during fermentation and aging is vastly reduced. It is possible to get a whole range of different beer types in home brew kits, even lager. Home beer making really is a lot easier than it used to be.
For me the advantages of making beer at home far outweigh the disadvantages. The taste of home made beer is pretty unique. There is a wide range of beer types you can make. You can make it as mild or as strong as you like. You have control over the ingredients you can use. As you become more experienced you can move from the safety of home brewing kits to making your beer right from scratch. It is a relaxing pastime and provides you with an immediate topic of conversation when friends come around to visit. All in all home brewing beer is lots of fun. Try it.
