Brazil has been experiencing a significant increase in craft beer production. According to the “Beer Yearbook 2021 – statistics on the brewing sector in Brazil”, released by the Ministry of Agriculture, Livestock and Supply (Mapa), the number of beer producing establishments reached the mark of 1,549, which represents an increase of 12.0 % compared to the previous year.
However, in order to carry out the beer production activity, the person interested in its production must have specialized equipment. After all, breweries must use different types of hoses for the traffic of beer, yeast and other traditional products in the segment. However, it is not every hose that has the appropriate capacities for the purposes that involve the manufacture of the drink.
Specific characteristics
To meet the specificities of beer production, a hose for liquid traffic needs to have three elements: inner tube, reinforcement and cover. Also called the “core”, the inner tube needs to resist halogenated, alkaline or oxidizing cleaning and disinfecting products.
It is also necessary to withstand sterilization, to be insensitive to copper ions (the “rubber poisons”) and to withstand physical and mechanical efforts.
Reinforcement gives the hose the ability to withstand pressure and vacuum, as well as other types of mechanical stress. Among them, the use of steam can require a lot of reinforcement, according to information from Cervesia, a company dedicated to brewing technology.
Finally, the cover is a component of the external part, whose function is to protect the reinforcement. It must withstand abrasion, cuts, contact with chemicals and various other forms of weathering.
How to make the right choice
According to Daniel Rodriguez, CEO of Maxxflex, a manufacturer of rubber hoses and hoses, it is essential to observe whether, even if the product is classified as for use in breweries, it has a rolled construction, a special non-toxic synthetic rubber tube, resistance to temperatures of up to 80ºC and straight ends.
Another important point to check is the white inner tube with a red outer tube and a white spiral band, a standard for this type of hose.
