Going Against the Grain: Nedox® PFAS-Free Coating Prevents Rice Cake Buildup at High Temperatures

Rice cakes may be light on calories, but keeping the machinery used to produce them in top working condition can be quite the challenge. These delicate snacks tend to crumble easily, which means any leftover grain residue on the equipment can lead to product defects, costly machine downtime, and lost profits. A prominent rice cake manufacturer approached us recently, seeking a solution to their sticky residue problems and aiming to reduce how often they had to stop production for cleaning. To craft those round, crispy snacks, manufacturers typically cook the rice grains under high heat inside a metal pan. A cylindrical press then applies pressure until the grains expand and fill the mold. After forming, the cakes are ejected onto a conveyor belt where they receive additional flavoring. However, the intense heat and pressure during this process cause rice to bake onto the pistons and sealing rings of the baking equipment, leading to frequent interruptions just to clean these parts. While the company understood that applying a coating could solve this problem, most coatings couldn’t handle the extreme temperatures involved—over 475°F. Despite testing numerous coatings from different suppliers, none met both the durability and release requirements needed for their machinery. That was when we introduced them to our Nedox® 10K3 coating. This PFAS-free surface treatment combines exceptional mold-release capabilities with high-temperature stability, all while meeting USDA and FDA compliance standards. These certifications make Nedox coatings ideal for food processing environments where product residues often stick to machinery. Additionally, Nedox excels in areas requiring frequent cleaning, simplifying maintenance routines and reducing downtime. Some of the standout features of Nedox include:

• Surface hardness up to Rc 68.
• Resists abrasive wear and prevents seizing.
• Offers chemical, acid, and alkaline resistance.
• Operates effectively between -250°F and +950°F, depending on the formulation.

Since implementing Nedox 10K3, the rice cake manufacturer has experienced zero sticking issues and significantly fewer interruptions for cleaning. When stubborn food residues threaten both product quality and machine uptime, it's crucial to consult with our team of experts to identify the best coating solution for your specific needs.
