 Advantages of using stainless steel in the food industry

Although today stainless steel is used in almost all branches of Polish, European and even global industry - it is relatively one of the youngest materials in mass use. It was patented about 110 years ago by German engineers. It found its first application in the food industry - an Englishman Harry Brearley, the creator of the term "stainless steel" after discovering that it does not rust in contact with vinegar and lemon juice, decided to convince the knife manufacturer R. F. Mosley to the idea.

In the following decades the world's engineers found many other applications for steel, but it is still a material commonly used in the food industry. What is the phenomenon of this material?

 

What is food grade stainless steel?

Although stainless steel, as a group of corrosion-resistant steels, is fully approved for contact with food and drinking water, austenitic steel - the most popular grade of stainless steel - is most commonly used. However, it is important that the manufacturer of finished steel products apply to the National Institute of Hygiene to confirm that the article can be safely used in contact with food. Steel behaves differently in different environments, and it may turn out that the National Institute of Hygiene suggests the use of a different grade of steel, for example due to the operating temperature of the device.

 

Use of stainless steel in the food industry

The use of stainless steel in the food industry is huge. Let's start with the fact that almost in every household kitchen we can find items made of this material. Knives, cutlery, pots, and even bowls - all this serves us every day during kitchen work, retaining all its properties for years. Stainless steel products are also widely used in the catering industry. It is used to make countertops in industrial kitchens, housings of household appliances, as well as sinks and fittings. Strictly in the food industry stainless steel is used as elements of installations in factories engaged in the production and processing of food. It is also used for, among others, dairy cisterns. Stainless steel, thanks to its unique properties, enjoys a very wide range of applications. It is worth taking a look at the reasons why it is so.

 

Why is it good to use stainless steel in the food industry?

Stainless steel is commonly used in the food industry because of its non-toxicity and ease of cleaning. This material does not react chemically with other substances and can be cleaned with high temperatures. In the process of disinfection, we can also use most of the available detergents - stainless steel is not absorbent and after rinsing its surface with water - we can freely use it for food processing. Not without significance, especially for entrepreneurs, is the fact that this material is extremely durable and does not require regular and expensive maintenance. Although stainless steel can be slightly more expensive than other raw materials, it is an excellent compromise between the interests of the consumer and manufacturer. Strict HACCP standards recommend that in contact with food this material should be used. It is also worth mentioning that stainless steel is ideal for recycling, because even after melting it retains its unique properties.
