food processing plastic scraper Non-Metallic Sludge Scrapers for Corrosive Media | 18-Yr Expertise

A food processing plastic scraper is engineered to meet the stringent hygiene and material safety requirements of the food and beverage industry while providing effective solids removal in wastewater treatment or process tanks. These applications involve effluents with high concentrations of fats, oils, greases (FOG), organic sugars, and cleaning agents, including caustic cleaners. The scrapers must be constructed from USDA/FDA-compliant materials that are non-toxic and will not leach any harmful substances into the process stream or wastewater. Plastics such as high-density polyethylene (HDPE) and ultra-high-molecular-weight polyethylene (UHMW-PE) are commonly used due to their excellent chemical resistance to cleaning agents and food products, their smooth, non-porous surface that prevents bacterial harborage, and their compliance with relevant food contact regulations. The design emphasizes easy cleanability to meet sanitary standards. Furthermore, their corrosion resistance ensures they withstand the aggressive cleaning-in-place (CIP) processes common in this industry. These scrapers are used in onsite wastewater pretreatment plants, equalization tanks, and dissolved air flotation (DAF) units where they efficiently remove food solids and FOG, preventing septic conditions and ensuring compliance with sewer discharge permits. We manufacture scrapers that meet the exacting standards of the food processing sector, ensuring both operational efficiency and regulatory compliance.
