Food processing and packaging.

THE BENEFITS

RESISTANCE TO PRODUCT ADHESION

Electropolishing achieves a bright, smooth finish that resists product adhesion and makes cleaning equipment much simpler.

REDUCED BUILDUP OF BACTERIAL BIOFILMS

Untreated metal products used in the food processing and packaging industry are vulnerable to bacteria accumulation, and these bacteria can be difficult to remove through chemical washes. Among many other finishing treatments--such as sanding or metal polishing--electropolishing has proven to be the most effective in preventing harmful contaminants, like Salmonella, from forming on products' surfaces.

1/3-A SANITARY FINISHING FOR DAIRY PRODUCTS

3-A sanitary standards originated in the 1920s for dairy and milk distribution to specify the criteria for the design and fabrication of equipment that comes into contact with food,2To comply with 3-A sanitary standards, parts can be electropolished. Electropolishing provides a clean, corrosion resistant surface ideal for food processing and packaging devices.

CASE STUDY

One of our customers required electropolishing on a 304 stainless steel hopper. Because the part was blasted during fabrication, the impingement on the metal surface made it susceptible to product buildup. The customer experienced severe product flow and cleaning problems during applications involving powdered food products.

Electropolishing enhanced the blasted surface. Electropolishing smoothed outthe imperfections left behind by blasting and other fabrication processes. Even microscopic imperfections cause product buildup and cleaning problems, but electropolishing eliminated even the smallest peaks and valleys on the surface of the alloy.

By eliminating surface defects on the surface of the hopper, electropolishing made the powder product flow more readily and improved cleaning times during normal product maintenance.
