Suggested Operating Conditions
| Condition | Fructose or HFCS (Ca²⁺ form) | Polyols (Ca²⁺ or K⁺ form) | Betaine (K⁺ form) |
|---|---|---|---|
| Syrup Temperature | 60 – 71°C (140 – 160°F) | 60 – 71°C (140 – 160°F) | 80 – 85°C (176 – 185°F) |
| Syrup pH | 4 – 7 | 4 – 7 | 7 – 12 |
| Dissolved Oxygen Concentration (Recommended) | < 0.1 ppm | < 0.1 ppm | < 0.1 ppm |
| Dissolved Oxygen Concentration (Maximum) | 0.25 ppm | 0.25 ppm | 0.25 ppm |
| Simulated Moving Bed Operation | With optimized tuning (annually) | With optimized tuning (annually) | With optimized tuning (annually) |
It is strongly advised to remove oxygen from feed streams and elution water; limiting dissolved oxygen to less than 0.1 ppm (0.25 ppm maximum) will help maximize resin life.
