Food grade screws (such as starch and chocolate extrusion screws) are prone to material adhesion and wear, and traditional repair materials do not meet food contact standards. Daokedao adopts food grade 316L stainless steel+PTFE composite melting technology, and the coating meets the FDA 21 CFR 175.300 standard. The surface friction coefficient is reduced to 0.07, and the material adhesion is reduced by 90%. The coating hardness is HRC50-52, the wear resistance is increased by 2 times, the surface roughness of the screw is Ra0.1 μ m, and it is easy to clean without residue. After repair, the lifespan of the screw has been extended from 6 months to 18 months, and the qualification rate of food products has increased from 96% to 99.8%, with no risk of material cross contamination. After being applied in a certain food machinery factory, the screw cleaning time has been reduced from 2 times per shift to 1 time per shift, and the single shift production efficiency has been improved by 20%, which is suitable for hygiene production scenarios such as food and medicine.
