HENGJI MAGNETICS: Optimizing Mining Operations with Advanced Magnetic Separation
Hengji provides advanced magnetic separation technology designed specifically for the rigorous demands of the Food & Pharmaceutical sectors. Our range of equipment effectively removes ferrous and weakly magnetic contaminants at various stages of production – from raw material intake and powder processing to liquid filtration, packaging, and recycling – ensuring product purity, safety, compliance with stringent standards (HACCP, GMP, FDA), and significant cost savings.
Application Summary :
I. Raw Material Initial Screening & Tramp Iron Removal
• Equipment: CQZ Series Pipeline Magnetic Separators (e.g., CQZ-300-3)
• Key Performance:
▫ Removes roll grinder fragments (≥0.1mm) from grains, flour, sugar, salt.
▫ Residual ferrous contamination ≤0.5 ppm.
▫ Features 316L stainless steel magnetic bars with surface flux density of 18,000 Gauss (1.8 Tesla).
▫ Withstands high-pressure steam sterilization (134°C / 273°F).
• Case Study :
A flour mill implemented the CQZ-250-4. It successfully eliminated 0.2mm roller fragments from wheat flour, achieving zero customer complaints related to metal contamination and securing HACCP certification.
II. Liquid Product Precision Filtration
• Equipment : CYG Series Liquid Magnetic Rod Filters (e.g., CYG-DN100)
• Key Performance :
▫ Captures 316L stainless steel particles (≤0.3mm) in liquids like soy sauce, vinegar, edible oil, preventing sediment formation.
▫ Standard flange connections for easy integration.
▫ Designed for Clean-in-Place (CIP) with compatibility for acid/alkaline cleaning solutions.
• Case Study: : A soy sauce producer installed a CYG-DN80 unit. It intercepted 0.3mm weld slag shedding from fermentation tanks, reducing bottled sediment complaints by 98%.
Ⅲ. High-Purity Powder Contaminant Removal
• Equipment : CXJ Series Dry Powder Magnetic Separators (e.g., CXJ-4080)
• Key Performance :
▫ Eliminates conveyor belt rust (≥0.1mm) from sensitive powders like milk powder, probiotics, vitamins.
▫ Achieves purity levels up to 99.99%.
▫ Constructed with 304 stainless steel sealed housing, meeting GMP cleanroom requirements.
• Case Study : An infant formula plant utilized a CXJ-3000Gs separator to remove iron particles from whey protein powder, eliminating costly metal contamination recall incidents.
Ⅳ.Packaging & Recycled Material Purification
• Equipment: RCT Series Magnetic Drum Separators (e.g., RCT-220600)
• Key Performance:
▫ Removes aluminum foil label pins (≥0.2mm) from PET bottle flakes.
▫ Ensures recycled material meets FDA food-grade standards.
▫ Features Tungsten Carbide-armored magnetic drum with 10-year lifespan, eliminating maintenance costs.
• Case Study : A beverage bottle recycler deployed the RCT-220660. PET flake metal impurities were reduced to ≤0.001%, saving ¥2 million annually in virgin material procurement costs.
Ⅴ. Sterile Line Protection
• Equipment: CTB Series Wet Magnetic Separators (e.g., CTB-44)
• Key Performance:
▫ Removes 316L pipeline wear particles (≤0.5µm) from injectables and infusion solutions, eliminating vascular embolism risks.
▫ Fully enclosed magnetic system design.
▫ Resists high-temperature sterilization (121°C / 250°F).
• Case Study : A pharmaceutical company installed CTB-44 units on their infusion filling lines. Visible particle inspection pass rates reached 100%, and the site achieved zero deficiencies during an FDA audit.
Highlighted Case Studies
• Infant Formula Manufacturer Eliminates Metal Contamination
▫ Problem: Customer complaints due to 0.2mm roller fragments contaminating milk powder.
▫ Solution: Installation of CQZ-250-4 Pipeline Magnetic Separators at the raw material intake points.
▫ Result: 100% interception of ferrous impurities, preventing potential annual recall losses estimated at ¥5 million.
• Pharmaceutical Injectable Safety Enhancement
▫ Problem : Detection of ≤0.5µm metallic particles in injectables posed embolism risks.
▫ Solution : Integration of CTB-44 Wet Magnetic Separators upstream of the filling line.
▫ Result : Elimination of metallic contamination, achieving a zero-defect outcome in FDA inspection.
