It goes without saying that, in the food and beverage industry, it is essential to maintain hygiene and efficiency. Stainless steel is a natural choice due to its durability, ease of cleaning, and non-stick properties, but regular exposure to liquids and chemicals can result in corrosion which can increase maintenance costs and impact the quality of the finished product.
Passivation is a highly effective technique that can enhance the durability and performance of stainless steel equipment, ensuring it remains free from corrosion and suitable for long-term use in the food and beverage industry.
Passivation is a chemical process that involves the removal of free iron from the surface of stainless steel to create a protective oxide layer that enhances the metal's resistance to corrosion. Typically, the process uses citric acid to remove contaminants and impurities, thereby ensuring that the stainless steel remains inert and resistant to environmental factors that, otherwise, could lead to corrosion.
Passivation is particularly important in the food and beverage industry in which equipment must withstand constant exposure to moisture, acids, and other corrosive substances to safeguard the quality of produce, protect consumers, and reduce unplanned maintenance and repair costs.
How passivation can maintain food and beverage standards:
A key benefit of passivation is its ability to significantly extend the lifespan of equipment used in the food and beverage industry. Stainless steel pipes, tanks, and machinery are expensive to purchase and install, so premature failure can lead to costly repairs or replacements. Stainless steel chemical cleaning helps to maintain the integrity of equipment, protecting it against corrosion and ensuring it is reliable and efficient in the long-term.
Adhering to industry standards is vital for the safety and quality of food and beverage produce. Regular passivation helps to ensure compliance with ASTM A967 regulations which establish the requirements for chemical passivation treatments for stainless steel parts. By meeting these standards, food processing equipment remains safe and suitable for use, preventing contamination and ensuring that products meet the necessary quality benchmarks.
In an industry in which efficiency is non-negotiable, downtime can be an obstacle to both productivity and profitability. Effective passivation and de-rouging processes are designed to minimise downtime and protect operational efficiency. By preventing the build-up of rust and other contaminants, passivation ensures that equipment remains in optimum working condition, meaning you business will experience fewer interruptions in production, smoother operations, and more consistent output.
