Failure to comply with these regulations can result in hefty fines, production shutdowns, and even legal action.
Investing in food grade struts is a proactive step towards ensuring regulatory compliance. By using certified materials and adhering to best practices for hygiene, food manufacturers can demonstrate their commitment to safety and avoid costly penalties. The peace of mind that comes with knowing your facility meets the highest standards is invaluable.
Contamination can negatively affect the taste, appearance, and shelf life of food products. Using non-food grade struts, which are susceptible to corrosion or degradation, introduces the potential for these materials to taint the product, thus decreasing appeal to consumers. The integrity of the product must be preserved to maintain the highest quality, therefore the use of food grade struts are essential to maintaining this.
Food grade struts are often designed with a focus on durability and the ability to withstand harsh conditions. The rigorous cleaning and sanitization processes common in food processing facilities demand materials that can resist degradation from strong chemicals and frequent washdowns. By using food grade components like struts, manufacturers can ensure a longer lifespan for their equipment and reduce maintenance costs. This durability translates to a greater return on investment over the long term.
Exploring Materials for Food Grade Struts
The choice of material for food grade struts is paramount. The material must provide strength, stability, and resistance to the unique challenges of the food processing environment. Here are some of the most common and effective materials:
Stainless steel is a widely favored choice for food grade applications due to its exceptional corrosion resistance, durability, and ease of cleaning. The non-porous surface of stainless steel prevents the buildup of bacteria and makes it easy to sanitize, thus making it an ideal material in food processing facilities. Within the stainless steel family, two grades are particularly prominent:
Stainless Steel Options
Type three hundred and four stainless steel offers excellent corrosion resistance in many food processing environments. It is a versatile and cost-effective option for a range of applications.
Type three hundred and sixteen stainless steel, known for its enhanced corrosion resistance due to the addition of molybdenum, offers protection against harsher chemicals and more aggressive environments, such as those with high salt content. It is often the preferred choice for coastal facilities or those processing particularly corrosive foods.
Speciality Polymers and Plastics
While stainless steel is a strong contender, specialty polymers and plastics offer several advantages in specific food processing applications. Food grade plastics like PEEK (Polyether Ether Ketone), PTFE (Polytetrafluoroethylene, commonly known as Teflon), and UHMWPE (Ultra-High-Molecular-Weight Polyethylene) provide unique properties:
These materials are significantly lighter than stainless steel, making them easier to handle and install. This can be particularly beneficial in applications where weight is a concern.
Many food grade plastics are highly resistant to a wide range of chemicals, including acids, bases, and solvents. This makes them suitable for use in environments where harsh cleaning agents are used.
These polymers are electrically non-conductive, reducing the risk of sparking hazards in areas where flammable materials are present.
Although some of these polymer materials have significant benefits, they also have a few limitations. Typically, polymer materials will not have as much structural strength as stainless steel and may be limited by the temperature constraints of their application.
