The food industry is one of the largest and most critical sectors in the global economy. It encompasses various segments, from agriculture and food processing to distribution and retail. As such, it requires specialized equipment and machinery to meet the industry's unique needs, including sheet metal fabrication.
Sheet metal fabrication is the process of creating metal structures or components by cutting, bending, and assembling sheet metal. It involves using various techniques such as shearing, punching, laser cutting, welding, and forming to transform raw sheet metal into functional products. In the food industry, sheet metal fabrication is essential to produce equipment and machinery that can withstand the industry's harsh conditions, hygiene requirements, and safety standards. HSJ, as a professional China sheet metal fabrication supplier, would like to talk about the uses of sheet metal fabrication in the food and beverage industry.
The food and beverage industry increasingly relies on stainless steel equipment and processing systems, which consume over 30 percent of the stainless steel produced. Stainless steel is a family of graded steels known for their corrosion-resistant properties, derived from alloying a minimum of 10.5% chromium to the material. This element oxidizes the surface of the steel, providing approximately 200 times more corrosion resistance than steels without chromium alloys.
Stainless steel sheet metal is an ideal material for fabricating equipment for the food and beverage industry for several reasons. Firstly, it has excellent mechanical properties, such as high strength and durability, high and low-temperature resistance, increased formability, and easy fabrication, making it long-lasting with an attractive appearance, all favorable properties for equipment fabricated for food industry applications.
Secondly, stainless steel is a food grade material because of its corrosion resistance. The chromium in stainless steel makes it nonporous, and food-grade stainless steels have a high chromium content, as well as nickel added. The majority of the stainless steel used in food applications contains approximately 16% to 18% chromium and 8% or 10% nickel, providing biocompatible and hygienic characteristics required to service a wide range of food and beverage media. Austenitic grades 304 and 316 are commonly used for the manufacture of products and equipment due to their high chromium content.
Thirdly, stainless steel is the choice material for food processing equipment due to its hygienic properties. It is specified in the 3-A Sanitary Standards, Inc. (3-A SSI), an independent, nonprofit association that provides design criteria for equipment and processing systems used in the production of dairy, food, and beverage products. Its publications have established the standards and consensus opinions used to protect food from contamination and ensure that product contact surfaces can be mechanically cleaned and sanitized easily.
Fourthly, stainless steel has easy-to-clean contact surfaces, making it ideal for meeting strict hygienic conditions. It is widely used in vats and tanks, refrigeration units, cookware, sinks, countertops, and tables. Stainless steel is also widely used for kitchenware and cutlery, from cookers, grills, and saucepans to knives, forks, spoons, and utensils. It is a germ-free material that, with proper cleaning, does not absorb or interfere with the taste of food or beverage.
Finally, stainless steel's formability and serviceability material allow the complex fabrication shapes and geometries often required on industry equipment. Combined with its non-corrosive properties and easy-to-clean surfaces, stainless steel is a highly serviceable material too, that can be sterilized repeatedly without deterioration.
Sheet metal fabrication provides a precise and customized solution for the unique requirements of the food industry. Equipment and machinery can be designed and fabricated to meet the specific needs of a food facility, including custom colors, shapes, sizes, logos, and other features. This includes equipment such as commercial kitchens, vending machines, food storage tanks, ventilation systems, kitchen washing tanks, and kitchen cabinets.
In the hospitality industry, precision is critical when it comes to machine shells, equipment parts, and other components. Equipment and machinery must be fabricated to exact specifications to ensure efficient and safe performance, as well as resistance to corrosion. Even minor deviations in dimensions or tolerances can result in equipment failure, downtime, and compromised food safety.
The food and beverage industry utilizes stainless steel in various applications, such as:
Countertops Stainless steel countertops are becoming increasingly popular in homes, restaurants, bars, and hotels due to their durability, resistance to stains, burns, and rust, and easy-to-clean surfaces. Stainless steel countertops can also be customized to suit different design preferences.
Hotel/Commercial Kitchen Hoods Hotel and commercial kitchen hoods are required by law to protect against fire hazards and contamination. The fabrication process for appropriately sized sheet metal panels involves forming, bending, and laser cutting for exact measurements and design details, which require attention to quality standards and details.
Coolers/Commercial Freezers Sheet metal fabrication is a cost-effective solution for coolers and commercial freezers due to its malleability and customizability, which reduces time and expense. Sheet metal is also easy to clean, durable, and ideal for temperature control.
Garbage/Refuse Receptacles Metal-based garbage receptacles are a better choice than plastic for controlling odor and promoting a sanitary environment, especially in commercial or residential kitchens. Metal is easier to clean and doesn't absorb liquids or odors. Sheet metal fabrication offers various design options to meet different kitchen needs.
Breweries Breweries use sheet metal in fermenters, custom tanks, and kettles, among other equipment. Local sheet metal fabricators are often preferred for their ability to design and manufacture high-quality products resistant to corrosion and contamination based on the brewer's design preferences and needs. Metal and metal fabrication also allow for bending, forming, and temperature control necessary for brewing processes.
