Specialized Pure Water System for Coffee Roasting Plants - Optimizing Extraction Efficiency and Equipment Protection
1. Why does coffee roasting require specialized water treatment?
Water quality directly impacts coffee quality and equipment lifespan
☕ Extraction Impact:
• Calcium and magnesium ions (hardness) cause over-extraction (prominent bitterness)
• Low-mineral water (TDS 50-150 ppm) enhances flavor complexity
🔧 Equipment Protection:
• Scale buildup clogs boilers/coffee machines (repair costs ↑30%)
SCA Standards: Ideal coffee water total hardness 50-175 ppm, pH 6.5-7.5 (as per the “Water for Coffee” guidelines).
2. Specialized RO System Design for Coffee
Precise control of mineral balance
① Three-stage purification process
1. Pre-treatment:
• Activated carbon filtration (removes chlorine/odors)
• Water softener (hardness reduced to <1 mg/L CaCO₃)
2. RO main unit:
• 98% desalination rate (TDS adjustable to 10-50 ppm)
3.Mineralization module:
• Adds food-grade magnesium/calcium (ratio adjustable)
② Scale Prevention Key Technology
• Automatic Flushing Program: Flushes RO membrane every 8 hours
• 304 Stainless Steel Piping: Corrosion-resistant design
• Scale Inhibitor Dosage (optional): For high-hardness water sources
3. Successful Case: Premium Coffee Brand Upgrade
Shanghai Roasting Plant Water Quality Improvement Project
Original Issue:
• Tap water hardness of 280 ppm (3 times the SCA standard)
• Boiler scale cleaning required once a month
Solution:
• Installation of a 2 T/H custom RO system
• Mineral ratio setting (Ca:Mg = 2:1)
Results:
✅ Extraction rate stabilized at 18-22% (previously 14-26%)
✅ Equipment maintenance costs reduced by 60%
✅ Won the 2024 Coffee Golden Cup Award
