Self-Cleaning Drawer-Type Magnetic Separator for Milk Powder Production Lines​

GMP Standards, Avoiding Secondary Contamination

Product Overview​

The Self-Cleaning Drawer-Type Magnetic Separator for milk powder production lines is a GMP-compliant iron removal device designed specifically for the dairy industry. It features a fully enclosed structure and food-grade materials to meet stringent cleanliness requirements in milk powder production. The system is equipped with a high-pressure flushing automatic cleaning mechanism, effectively removing ferromagnetic impurities from milk powder while preventing secondary contamination. Through an intelligent control system, it enables timed or on-demand automatic cleaning, meeting the needs of continuous and automated milk powder production lines, and ensuring the quality and safety of high-end products such as infant formula.

Product Advantages​

1. GMP Standard Compliance: The equipment meets food-grade (3A, FDA) and pharmaceutical-grade (GMP) hygiene standards. Contact parts are made of 316L stainless steel with a surface roughness ≤ Ra 0.8 μm, suitable for cleanroom environments.

2. Zero-Contamination Design: Fully enclosed structure, no consumable contamination. High-pressure flushing uses purified water or food-grade solvents, eliminating secondary contamination risks.

3. High-Efficiency Iron Removal: High-gradient magnetic field design can adsorb ferromagnetic impurities as small as 1 μm, with an iron removal rate ≥ 99.8%, ensuring milk powder iron content complies with national standards.

4. Intelligent Control: Equipped with a PLC control system supporting remote monitoring and data logging, enabling unattended operation.

Case Benefits​

A self-cleaning iron removal system was implemented in a renowned dairy company’s infant formula production line, delivering the following benefits:

• Quality Improvement: Iron content in products controlled below 1 ppm, meeting EU standards. Product qualification rate increased by 15%.

• Certification Achievement: Successfully passed GMP and HACCP certifications, gaining access to high-end markets.

• Cost Savings: Reduced manual cleaning operations, saving 60,000 CNY annually in labor costs. Avoided rework losses of approximately 200,000 CNY due to iron contamination.

• Brand Value: Stable product quality reduced customer complaints to zero, significantly enhancing brand reputation.

Q&A​

Q1: Does the equipment comply with infant formula production standards?​

A1: Fully compliant. The equipment uses 316L food-grade stainless steel with surface finishes meeting GMP requirements, suitable for high-end products such as infant formula and medical-purpose formula foods.

Q2: Does high-pressure flushing affect milk powder quality?​

A2: No. High-pressure flushing uses food-grade purified water or solvents, followed by automatic drying to prevent moisture residue. The flushing process is conducted in a sealed chamber without contact with the product, ensuring milk powder quality remains unaffected.

Q3: What is the equipment maintenance interval?​

A3: Routine cleaning is required once a week. Core component maintenance is needed every 6–12 months. Maintenance procedures are simple, and the company provides regular inspection services and technical guidance to ensure long-term stable operation.
