Diamond Donut Case Study

The snack food manufacturer selected Diamond’s 300 series stainless steel roller chain as the solution for this application. 300 series is an ideal solution for food handling purposes in that it provides excellent corrosion resistance, has very low magnetic permeability and is considered non-sparking, which is especially important when working with oil in fryer applications.

Although initially considered a concern, lubrication turned out to be an insignificant issue. Traditionally, a mineral oil based lubricant is used for chain in food applications, but this wasn’t an option due to contact with the oil. Instead, the hot oil from the fryer acted as the chain’s lubricant, while an oil filtering system ensured that contaminants were removed from the frying trough in order to prevent contamination and buildup in the chain’s pin and bushing area.
