Why should the stainless steel of beer equipment be polished?

The brewery equipment is made of stainless steel, a material that can be polished to a high sheen. This polishing process, called mechanical polishing, gives beer equipment an attractive appearance and makes it more durable. The reason why beer equipment should be polished is to maintain its cleanliness and hygienic performance. Polished stainless steel helps prevent the growth of bacteria and other microorganisms, preventing them from adhering to surfaces in kegs, tanks, pipes, and more.

Polished stainless steel is more resistant to corrosion and thus helps you get the most out of your equipment. For example, polished stainless steel is more hygienic because it is easier to clean and does not keep dirt and bacteria like unpolished stainless steel.

Welding And Heat Treatment

Welding and heat treatment are two important factors to consider when selecting steel for brewing equipment. Welding is a joining process in which two pieces of metal are joined together by heating until they melt and then allowing them to cool together. The result is often a seamless joint stronger than the original metal.

Food Hygiene Requirements

If you’re in the beer business, you know that food hygiene is important. This is required by law and health authorities. There are several different levels of food hygiene standards that need to be met. Not only does it affect the safety of your customers, but also their perception of your brand.

The Brewing Equipment Institute has said polished stainless steel has a smooth surface that won’t inhibit the growth of bacteria or mold. But, if water containing harmful bacteria comes into contact with this metal (and then food), it can cause serious problems.

Effect Of Mechanical Polishing On The Quality Of Beer Equipment

To polish a surface, you need to know its true color. When the oxide layer on stainless steel is removed, it exposes the pure metal underneath. This can be used to determine if your equipment has rusted, or if there are any contaminants in your beer production process. Polishing also removes any dirt or oil that may have accumulated on this part of the device during use, which can affect how your drink tastes later!

Beer Equipment Production Polishing Process

  • Seam weld the stainless steel plate into a cylinder and a cone bottom.

  • Weld the pit plate on the cylinder body and the cone bottom.

  • Grinding the inside of the cylinder. First, workers manually polish to remove some obvious weld slag. Secondly, use professional machines with different abrasive belts for further polishing, 80 mesh belt (RA=0.2mm)→120 mesh belt (RA=0.12mm)→240 mesh belt (RA=0.6um)→400 mesh belt (RA=0.2mm) microns).When the mesh belt is 240 mesh, the RA inside the tank is 0.4-0.6um, the inside of the tank is hygienic and can be used for brewing beer. For some strict brewers, they will require RA to be lower than 0.4um, so we will use a 400-mesh sand belt to improve the polishing accuracy.Sand the cone bottom inside. Same as cylinder. Polished dish top. Same with cylinder and conical bottom.

  • Assemble and weld the top, cylinder and bottom together.
