Spray Continuous Pan® (SCP®)
SED’s modular design vertical continuous pan with multiple chambers having honeycomb calandria features a bundle of tubes arranged in a honeycomb pattern without traditional top and bottom tube plates. A central downtake, equipped with SED’s uniquely designed six-blade mechanical circulator, boosts massecuite circulation for uniform crystal growth, higher exhaustion and higher heat transfer within the tubes. Automated chamber bypass system enhances the cleaning cycle efficiency as needed, while the overhead storage tank ensures an uninterrupted supply of feed and water to the SCP.
Working Principle
Heat Transfer
Steam or vapour condenses on the outside of the tubes, transferring heat to the feed (juice/massecuite) inside the tubes. This causes water to evaporate, concentrating the solution. The honeycomb calandria design enables operation at a lower temperature difference (ΔT), ensuring efficient evaporation and controlled crystallization while minimizing sucrose degradation.
Massecuite Circulation
Efficient circulation is promoted by the large central downtake and optimized honeycomb tube arrangement. This ensures uniform flow throughout the calandria, preventing localized overheating, eliminating stagnant zones, and maintaining consistent concentration across the pan.
Evaporation and Crystallization
As evaporation progresses, the liquor becomes supersaturated, initiating and sustaining crystal growth. Continuous circulation keeps crystals uniformly suspended, ensuring homogeneous growth and a narrow crystal size distribution. The generated vapours are either condensed in a condenser or reused through Mechanical Vapour Recompression (MVR), reducing overall energy consumption.
Continuous massecuite Discharge
Massecuite discharge to the crystallizer can be configured either from the bottom via pumping or from upper chambers through gravity flow, based on site conditions and the type of massecuite (A, B, C, or Refined).
