What comes to your mind whenever someone says stainless steel? There are chances you would visualize your kitchen if you are Indian. well, Indians have a deep relationship with steel. Our day starts with drinking water from stainless steel glass. our mother still carves the family name whenever she buys even a single dish. in the school days, we used to get our food packed in the classic steel bento lunch box. Some of us still use steel to show the anger by smashing it on the floor but don’t we all think it’s convenient 1st you release your anger by throwing and smashing things and 2nd The things that you throw are not going to be destroyed because it is made up of stainless steel. let’s come to the point do you know that stainless steel just don’t find their uses in the kitchen but it also is used in making your favorite food and drinks Let’s dive deeper and learn the various application of stainless steel pipes in the food and beverage industry.
Why Stainless Steel is used in Food Industry?
Stainless steel is a specific iron-based alloy that contains approximately 11% chromium. Other metals, like nickel, and other elements like carbon are included in the alloy. This special elemental makeup of stainless steel gives it the characteristics that make it valuable in a wide range of industries, primarily those where the metal will be exposed to harsh or difficult environmental conditions
A "specific release limit" (SRL) is the maximum amount of a given metal ion or metalloid ion (in mg) when released from a material or article with a defined surface area into food (in kg) or food simulants.
Metals and alloys used in food contact materials and articles must adhere to strict release limits (SRLs). The SRL limits of the majority of the alloying elements are specified in the list. For example, the SRL limit for nickel is 0.14 mg/kg of food, while the limit for chromium is 0.250 mg/kg.
Although food-grade stainless steel is ideal for sanitary food handling applications, not all stainless steel is food grade. Steels are assigned grades based on how they perform in various tests and requirements. The qualities we're looking for in stainless steel are quality, durability, and temperature resistance. Stainless steels that pass the test are safe for food preparation, storage, and consumption.
Stainless steel is exposed to heat, water, and harsh cleaning chemicals in the food industry. Food grade stainless steel should always stay durable, rust/corrosion free, and easy to clean as a result of these exposures. Besides that, the competing resistance means that it maintains an easy-to-clean and maintain surface. Finally, because the metal is resistant to heat, it can be exposed to high temperatures without being damaged.
What is Austenitic & ferritic stainless steel?
The most common stainless steels are austenitic.
Austenitic steels are non-magnetic stainless steels with high chromium, nickel, and low carbon levels.
They are known for their formability and corrosion resistance. 300 series austenitic plates of steel are nickel-based austenitic steels. The most commonly used grade is 304
Ferritic Stainless Steel
Ferritic stainless steel, on the other hand, is defined by a chromium content of 10.5% to 30%.
Keep in mind that ferritic stainless steel cannot be hardened through heat treatment. For instance, hot rolling will not harden ferritic stainless steel. Only cold treatment, like cold rolling, can harden ferritic stainless steel. Even so, ferritic stainless steel is hardening resistant. It may harden to some extent, but there will be no discernible difference in hardness.
How is Stainless Steel Used in Food Industry?
Let’s understand exactly how many places the food industries use stainless steel and if you look forward to today, you can find stainless steel's uses in a wide range of commercial food applications, in the kitchen.
What makes the grade 316 alloy an ideal food-grade steel sheet material is the fact that it has a high resistance to chemicals like acids, alkalis, and chloride-like salt. austenitic stainless steels, such as grade 304 SS, can suffer from corrosion damage when exposed to salt, which is often present in food products.
316 makes for fantastic food-grade stainless steel containers for nearly every food application.
The striking difference between 316 and 430 is the amount of nickel content present in 430 that makes it more affordable for many food makers 430 ss also resists nitric and organic acids furthermore it gives resistance against sulfur and oxidation.
Benefits of Stainless Steel in Food Processing Plants
When it comes to the food and beverage industry, it is vital that products are properly formed, stored, and transported. This is necessary to ensure that the products are safe to consume and last as long as they should. And, considering the significance of properly handling food and beverage products, an increasing number of plants are investing in stainless steel products such as sanitary valves, sanitary clamps, and stainless steel sanitary strainers. This article will go over a few of the most important advantages of using stainless steel products and equipment.
It is temperature resistant
Stainless steel can be used in both cold as well as hot temperatures. As a result, it is ideal for all aspects of food and beverage production. From withstanding hot temperatures during manufacturing to holding up well in cold storage locations, stainless steel products and equipment are adaptable when it comes to withstand various conditions.
It has a long lifespan
There are few materials that can compete with stainless steel in terms of longevity. Under normal conditions, stainless steel products can last for more than a century. As a result, it is ideal for use in food and beverage processing plants. Manufacturers will not have to replace stainless steel sanitary valves, pipe fittings, or other equipment. Furthermore, if food products must be stored for an extended period of time, stainless steel will perform admirably.
It's easy to clean:
When working with food and beverages, keeping a clean environment is critical. This is why using stainless steel equipment can be advantageous; stainless steel is extremely easy to clean. As a result, it can aid in the prevention of contamination and the spread of bacteria to food and beverage products. When manufacturers use a material that is simple to clean, they can be confident that their products are safe.
The Bottom line
Apart from their intriguing appearance, stainless steels have a diverse range of other qualities that are essential in the hygienic preparation of foods and beverages. They are unreactive in most foods, are easily fabricated, are long-lasting, and, when failures occur,
The material is recyclable despite seeming to be obsolete. The appropriate steel grade for a given application, designed into equipment with hygiene in mind and prepared with care will provide numerous benefits. years of dependable service, making it an excellent investment
It's important to choose materials that are appropriate to use when working in the food and beverage processing industry. So keep these benefits in mind when looking for an
