Magnetic Separation Solutions for Food and Pharmaceutical Industries
Hengji Magnetic & Electrical serves as a critical partner in sectors where product purity and safety are non-negotiable. Our advanced technology acts as a reliable quality guardian, dedicated to the efficient removal of both ferrous and weakly magnetic metallic impurities from raw materials and process streams.
In the demanding field of magnetic separators in food processing, our equipment ensures the purity and safety of everything from powders to liquids, protecting both consumers and expensive processing machinery from metal contamination. Similarly, our high-grade pharmaceuticals metal separator solutions are engineered to meet the industry’s stringent Good Manufacturing Practice (GMP) standards, reliably detecting and removing fine metallic particles from active pharmaceutical ingredients and excipients.
Our targeted solutions are designed to meet the strict hygiene and performance requirements of these sensitive industries. Constructed with food-grade and pharmaceutical-compliant materials, our separators support our clients’ commitment to excellence, providing peace of mind and safeguarding brand reputation. By ensuring the absolute integrity of final products, Hengji’s technology becomes an indispensable component in modern, responsible production lines.
Applications in Food Processing
Hengji provides specialized solutions for the critical application of magnetic separators in food processing, ensuring product purity across diverse materials from dry powders to liquid slurries.
Purification of Powdery and Granular Raw Materials
For bulk ingredients like flour, starch, sugar, and seasonings, we offer automated solutions. Our CQZ Series Fully Automatic Magnetic Separators install directly in pneumatic conveying lines, providing continuous, non-stop protection by automatically ejecting captured ferrous contaminants. This eliminates manual cleaning and prevents production line contamination. For applications requiring superior precision, our CTQ Series Roller Magnetic Separators utilize a high-intensity magnetic roll to effectively remove even fine iron rust and stainless steel particles from materials distributed via vibrating feeder, ensuring thorough purification for high-volume operations.
Purification of Liquid and Slurry Products
Liquid products like juices, dairy, sauces, and syrups require dedicated protection. Our CYG Series Pipeline Magnetic Filters install directly into process piping, featuring multi-layered magnetic rods or grids that capture microscopic metal particles from flowing liquids. Constructed from food-grade stainless steel (SUS304/316) with hygienic quick-release connections, these filters comply with stringent sanitary standards while enabling easy disassembly for thorough cleaning. Magnetic rods also offer flexible installation in hoppers, chutes, or as magnetic grates for comprehensive protection.
Specific Industry Applications
In grain processing for rice, beans, and cereals, our Permanent Magnet Drums and Plates remove tramp metal like nails and screws after cleaning stages, preventing damage to downstream milling equipment. For final products including tea and health supplements, our systems provide essential final-stage iron removal to guarantee product purity and protect brand reputation. This same engineering precision and hygiene standard forms the foundation of our pharmaceuticals metal separator solutions, where we adapt these proven technologies to meet even more rigorous GMP requirements for drug manufacturing.
Applications in the Pharmaceutical Industry
The pharmaceutical industry maintains absolute zero tolerance for metallic impurities, where contamination poses critical safety risks. A reliable pharmaceuticals metal separator is therefore indispensable throughout the manufacturing process, serving as a final safeguard for product integrity.
Protection of Active Pharmaceutical Ingredients (APIs) and Excipients
Before processing, all powdered materials including APIs and excipients such as lactose and microcrystalline cellulose must undergo rigorous purification. Hengji’s CQZ Series Automatic Separators and high-intensity magnetic rods effectively remove metallic contaminants introduced during production or transport, providing essential source protection. This application shares technical principles with magnetic separators in food processing, but is engineered to meet more stringent pharmaceutical requirements.
In-Line Protection During Production
Our Pipeline Magnetic Filters provide continuous protection within liquid transfer systems, capturing metallic particles generated by equipment wear in pumps and valves. This is particularly crucial for injectables and sterile solutions where even microscopic contaminants are unacceptable.
Compliance with Strict Industry Standards
Our pharmaceutical-grade systems are designed for full GMP compliance. Product-contact surfaces utilize high-quality stainless steel with electrolytic polishing and seamless construction to prevent bacterial harborage and enable sterilization. The robust design facilitates cleaning validation and equipment qualification (IQ/OQ), directly supporting our clients’ regulatory compliance efforts while ensuring absolute product safety.
Summary of Key Advantages
Across both food and pharmaceutical applications, Hengji Magnetic Separators share common strengths that make them the ideal choice:
-
High Efficiency and Thoroughness: Utilizing high-performance Neodymium (NdFeB) magnetic sources, our equipment generates powerful magnetic fields capable of removing micron-sized ferrous impurities.
-
Hygienic and Safe Design: Materials and construction comply with sanitary standards. Surfaces are easy to clean and maintain, preventing cross-contamination and secondary pollution.
-
High Degree of Automation: Supports continuous production, minimizes manual intervention, and reduces both labor intensity and contamination risks.
-
Clean and Energy-Efficient: Permanent magnet units operate without electricity, consuming no energy and introducing no pollution during the separation process itself.
-
Customized Service: We provide tailored iron removal solutions based on specific customer material characteristics, site conditions, and capacity requirements.
In conclusion, Hengji Magnetic & Electrical equipment has become an indispensable part of the quality management systems—such as HACCP and GMP—in food and pharmaceutical manufacturing, providing a solid foundation for ultimate product safety and quality.
