🌾 Project Overview: Sugar Refining Iron Removal Solution
Mag Spring® successfully delivered a 12,000Gs automatic magnetic separator for sugar plant operations, solving critical iron contamination challenges in sugar production and refining lines. This case study documents how our anti-stick coating technology and Siemens PLC control system eliminated sugar film buildup and bar jamming issues.
⚙️ Engineered Solution: Food-Grade Magnetic Separation
The new Mag Spring® automatic magnetic separator for sugar plant integrates Siemens PLC control, a fully welded stainless-steel housing, and high-intensity neodymium (NdFeB) magnetic bars. Every component is designed for 24/7 automated operation in humid, viscous, and high-sugar-content environments.
Technical Specifications：
| Specification | Details |
|---|---|
| Magnetic Strength | 10,000-12,000 Gs (High-intensity NdFeB) |
| Control System | Siemens PLC with automated iron discharge |
| Housing Material | Fully welded 304/316L stainless steel with mirror finish |
| Operation Mode | Continuous automatic demagnetization and cleaning |
| Application | Sugar plant, syrup filtration, food processing |
| Certification | ISO 9001, FoodSafety.gov compliant |
These features make it an ideal magnetic separator for sugar plants where cleanliness, consistency, and production uptime are critical.
🧲 Customer Challenges: Traditional Separator Problems
1️⃣ Problem 1: Sugar Film Formation on Magnetic Bars
In conventional systems, sugar solution and syrup tend to crystallize on the surface of magnetic bars, forming a sticky sugar film that severely reduces magnetic strength and trapping efficiency.
👉 Mag Spring® solves this with a proprietary anti-stick coating and a streamlined internal flow design, ensuring smooth material passage and eliminating film buildup. This maintains a constant magnetic field and optimal iron removal performance.
The Challenge: In conventional magnetic separator systems, sugar solution and syrup tend to crystallize on the surface of magnetic bars, forming a sticky sugar film. This buildup severely reduces magnetic strength and iron trapping efficiency.
Our Solution: Mag Spring® developed a proprietary anti-stick coating combined with streamlined internal flow design. This ensures:
- Smooth material passage without crystallization points
- Elimination of sugar film buildup
- Constant 12,000 Gs magnetic field strength
- Optimal iron removal performance 24/7
Client Quote: “The anti-stick coating reduced our cleaning frequency by 70% and maintained consistent magnetic performance.” — Sugar Refinery Client, Thailand
2️⃣ Problem 2: Magnetic Bar Jamming During Cleaning
Manual or semi-automatic separators often suffer from bar locking or jamming, especially after long operation in sticky sugar environments.
👉 The Mag Spring® system uses a pneumatic drive mechanism synchronized by Siemens PLC, designed to support smooth demagnetization and discharge operation..
3️⃣ Problem 3: Cleaning Cycle Management
In many sugar plants, magnetic efficiency decreases as cleaning intervals lengthen.
👉 Magnetic efficiency may vary with cleaning frequency. This automatic separator performs scheduled self-cleaning cycles to help maintain magnetic performance.
4️⃣ Problem 4: Hygiene & Corrosion Protection
The system’s fully welded sanitary structure eliminates dead corners where residues might accumulate. Combined with food-grade polishing and corrosion-resistant alloys, it ensures full compliance with sugar and food industry safety standards.All contact parts meet international ISO 9001 and FoodSafety.gov guidelines for food-contact equipment.
Before vs. After: System Performance Comparison
| Metric | Traditional Separator | Mag Spring® 12,000 Gs System |
|---|---|---|
| Magnetic Strength | 8,000-10,000 Gs | 12,000 Gs |
| Cleaning Method | Manual / Semi-automatic | Fully automatic PLC control |
| Sugar Film Buildup | Frequent crystallization | Special Design prevents buildup |
| Bar Jamming Issues | Common during cleaning | Pneumatic drive, jam-free operation |
| Maintenance Downtime | 4-6 hours/week | Less than 1 hour/week |
| Food-Grade Compliance | Variable | ISO 9001 + FoodSafety.gov certified |
