[Food Sanitation Law Compliance] Eliminates the sticking and chocolate stoppages of highly adhesive dough! With excellent blade release, it improves yield and dramatically reduces cleaning time.
This is a surface treatment solution for metal "slitter rolls" used in the manufacturing lines of food products such as cookies, biscuits, bread, and noodles, which cuts and divides sheet-like dough into a consistent width. We apply fluoropolymer coatings such as PTFE and PFA, which have the highest level of non-stick properties (release properties), to highly adhesive dough. Using our unique precision technology, we create a uniform and smooth coating on the blade edges, roll grooves, and fine steps, effectively preventing the adhesion and sticking of sticky dough containing moisture, oil, sugar, and gluten. 【Benefits of Implementation】 ■ Prevention of chocolate stoppages and stable operation Our excellent release properties eliminate problems caused by dough sticking to the blade edges or being drawn in, preventing line stoppages (downtime) and improving operational efficiency. ■ Improved yield and stable quality Smooth separation from the blade prevents pulling and deformation during cutting, achieving uniform product dimensions and reducing defect rates. ■ Reduction in cleaning and maintenance time By preventing sticking and adhesion, cleaning tasks become easier, significantly shortening cleaning time. We will propose the optimal fluoropolymer specifications according to the dough characteristics (hardness, adhesiveness) and the usage environment.

basic information
【Target Parts for Processing】 ■ Slitter rolls, round blades, cutters, cutting blades, and general forming and cutting guide parts for food manufacturing and processing 【Applicable Coating Materials】 ■ PTFE (Polytetrafluoroethylene) ■ PFA (Perfluoroalkoxy alkane) * The optimal paint and film thickness are selected according to the shape of the workpiece, the stickiness of the material, processing temperature, and cleaning conditions. 【Main Functions and Features】 ■ Excellent non-stick properties (release properties): Strong adhesion prevention effect guards against material entrapment and burning. ■ Uniform and smooth precision film formation: Precise coating down to the details of complex blade edges and groove shapes. ■ Safety and hygiene: Coatings that comply with the Food Sanitation Act (Ministry of Health, Labour and Welfare notification) are used. ■ Wear resistance and chemical resistance: Strong durability against routine cleaning and chemical wiping. 【Available Sizes】 ■ Flexible support from small tabletop machine parts to large automated line long rolls (prototype and test construction are also accepted).

Applications/Examples of results
【Main Uses and Application Areas】 ■ Dough cutting and slitting processes in food, confectionery, and bakery factories ■ Noodle cutting and slitting sections for various types of noodles (ramen, udon, pasta, etc.) ■ Cutting and processing lines for prepared foods, frozen foods, and pet food 【Implementation Results and Improvement Effects】 ■ Confectionery manufacturer (cookie dough cutting line) - Issue: Dough containing sugar and fat adhered to the slitter blades, frequently causing dough to wrap around and resulting in chocolate stoppages. - Effect: After applying PTFE coating, blade release dramatically improved. Chocolate stoppages significantly decreased, reducing downtime for cleaning and recovery by several dozen hours annually. ■ Bakery manufacturer (dough shaping and dividing line) - Issue: Many products had shape defects (deformations) due to dough pulling, leading to decreased yield. - Effect: By adopting PFA coating, the cut surfaces became very smooth, preventing deformations. The yield of the products significantly improved.

Company information
Nikken Coating Industry Co., Ltd. has been a specialized manufacturer of functional coatings for contract processing, earning the trust of customers across various industries for 79 years since its founding. We leverage our processing technology to maximize the properties of fluororesins, such as non-stick, lubricity, and chemical resistance, providing high-performance coatings that directly address customer challenges, including "Thermo Pro Release" for thermal welding processes and "NonStick STC" for blades and precision molds. In recent years, in response to movements regarding regulations on fluorinated compounds (PFAS), "PEEK resin," which is gaining attention as a substitute for fluororesins, has become a focus. Nikken Coating Industry commercialized the world's first PEEK resin coating, "PEEKCOAT," in 1999. Based on the solid knowledge and know-how accumulated over more than 20 years, we are further intensifying our research and development efforts to explore the potential of next-generation PEEK coatings! We aim to be recognized as "the go-to for PEEK coatings" and will continue to lead the way. As "the best partner for functional coatings that builds trust through technology," Nikken Coating Industry will continue to contribute to the creation of high-quality, high-performance products.
