The use of stainless steel in the construction of a wine production: which brand to choose, what to look for when choosing, manufacturer, examples of errors, and incorrect assemblies?
Recently, this material has been used in the creation of wineries and the reconstruction of previously built ones. The fact is that stainless steel has a lot of positive characteristics that make it so popular:
Anti-corrosion properties - the metal does not lend itself to rust even in the most aggressive conditions;
High-temperature conditions for melting; a large selection of various stainless steel products:
Easy to process; simple assembly scheme, both by welding and using hardware products; high service life of the material;
Construction of load-bearing structures of a winery
Depending on what tasks will be performed at the plant (processing, storage, packaging, etc.), the materials required to construct workshops are determined. Often, lightweight structures are used for this, allowing you to quickly, efficiently, and economically erect a building of the required size and characteristics.
The metal is used in grades as it is suitable for the food industry. In some cases, a higher alloyed metal is required, but only when there is direct contact between the product and the metal. In other cases, this will be an extra cost, in which there is no need. Metal Fabrication Singapore offers you the best quality stainless steel.
Tanks for storage and processing of wine
As you know, the best material for storing wine and wine products is oak. It has a lot of positive characteristics, including the presence of special substances that are transferred to the drink during the storage of wine, enriching and improving its quality.
However, this material also has its drawbacks, namely, the high cost and favourable environment for the cultivation of bacteria. That is why sulphur is used for treating barrels, with which wood is cleaned. Sulphur is not dangerous to humans, but it gives a characteristic taste and smell, especially champagne, which quickly absorbs these impurities.
Stainless steel is used in winemaking because of its high corrosion resistance to wine and grape juice. For storage and processing of these products, it is customary to use special stainless steel options, which include the following elements:
- chromium - from 12% to 20%;
- nickel - from 1.3% to 11%:
- molybdenum - from 0.5% to 3%;
- titanium and carbon alloys can be used no more than 0.5%.
Errors when using stainless steel
Molybdenum is a very important element in stainless steel. It is on him that the rusting process depends on contact with wine juice. If this element is absent in stainless steel, then the metal is negatively affected by sulphurous acids and sulphated products from grapes. The process is accelerated several times if the tanks used are not filled with the product. This is due to oxidation, which increases due to the oxygen content in the gas state. Metal Works Singapore supplies the best stainless steel.
Workmanship
The metal processing process is equally important. The stainless steel must be polished, and if necessary, several cycles of polishing or treatment with anti-corrosion compounds are carried out. They must be carried out without the use of oxygen, and the welding electrodes must be suitable for the grade of metal used. Internal seams are cleaned with abrasive materials.
