Why Should The Steel Used In Beer Equipment Be Polished?

    Beer equipment is made from steel, which is a material that can be polished to a high shine. This process of polishing is called mechanical polishing and gives beer equipment an attractive appearance as well as making it more durable. The main reason why beer equipment should be polished is to maintain its cleanliness and hygienic properties. Polished stainless steel helps prevent the growth of bacteria and other microorganisms by preventing them from attaching themselves onto the surface of your kegs, tanks, pipes etc.

    Polished stainless steel is more resistant to corrosion, so it can help you get the most out of your equipment. As an example, polished stainless steel is more hygienic because it’s easier to clean and doesn’t retain dirt and germs like unpolished stainless steel.

    Another benefit of polished stainless steel is its appearance. The mirror finish makes any piece look more contemporary and attractive than an unpolished counterpart.

    Welding And High Temperature Treatment


    Welding and high temperature treatments are two important factors to consider when selecting steel for your brewing equipment. Welding is a joining process in which two pieces of metal are joined together by heating them until they melt, then allowing them to cool together. The result is often a seamless joint that is stronger than the original metals. High temperature treatments involve heating the steel to extremely high temperatures (around 1500° F) in order to increase its strength and durability while also improving its corrosion resistance and eliminating internal stress caused by cooling from an elevated temperature after welding.

    In general, most steels used in beer equipment have been treated with either or both of these processes; however, some manufacturers may use alternative processes or no treatment at all if they find it unnecessary due to other factors such as cost or ease of production.

    Food Sanitation Requirements


    If you’re in the beer business, you know that food sanitation is important. It’s required by law and health authorities. In fact, there are a few different levels of food sanitation standards that need to be met. Not only does it affect the safety of your customers, but it also impacts their perception of your brand.

    The Beer Equipment Institute has stated that polished stainless steel will not inhibit the growth of bacteria or mold because of its smooth surface; however, if water containing harmful bacteria enters into contact with this type of metal (and then enters into contact with food), it can cause serious problems.

    Effect Of Mechanical Polishing On Quality Of Beer Equipment


    In order to properly polish a surface, you need to know its true color. When the oxide layer on steel is removed, it exposes the pure metal underneath. This can be useful for determining whether or not rust has formed on your equipment or if there are any contaminants present in your beer’s process. Polishing also removes any dirt or oil that may have accumulated on this part of your equipment during use, which can affect its taste later on down the road when you drink it!

    The steel used in beer equipment is polished for several reasons.

    Polishing the surface of stainless steel is a process that involves rubbing and buffing it to give it a mirror-like finish. It’s important to note that there are different kinds of polishing, but for the sake of this article, we will only discuss what happens during “polishing.”

    The process of polishing stainless steel is done for several reasons:

    • Polished stainless steel is easier to clean and sanitize. Because polished surfaces have no pits or grooves, they can easily be cleaned with high-pressure detergent sprays or other disinfectants like bleach. This helps prevent bacterial growth in beer equipment since no place on a polished surface will harbor water where microbes may grow. The smoother the surface is made, the less likely any microorganisms will be able to cling onto its texture and thrive inside your brewery equipment (or anywhere else).

    Beer equipment production polishing process.


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

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

    3. 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.

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

    Internal: overall pickling and passivation treatment, internal polishing to 0.2~0.4μm without dead angle.

    External: Outsourcing oil film brushed board surface protection, welding seams are polished.

    High quality stainless steel beer brewing equipment

    Vdobrew’s beer brewing device is a high-quality product that uses a variety of processes to ensure that your device is perfect.

    First, we do an overall pickling and passivation treatment, which means that we remove any contaminants from the inner workings of the device. Then we polish it to 0.2~0.4μm without dead angle, which ensures that all parts are smooth and shiny.

    The external surface of Vdobrew’s beer brewing device gets outsourced oil film brushed board surface protection, which helps to keep it looking new for longer and makes cleaning easier. The welding seams are also polished so they don’t rust over time—so if you’ re looking for something durable and reliable, this could be the perfect choice!
