SRI’s continuous vacuum pan design is factory proven and produces excellent massecuite exhaustion, with 13 installations in three countries to date.
SRI pans are designed to:
- Produce strong massecuite circulation;
- Provide uniform conditions for crystal growth at any section along the pan;
- Generate narrow crystal size distribution;
- Minimise the number of control instruments;
- Provide easy access to calandrias for maintenance;
- Simplify valving and feed pipework; and
- Augment production capacity by the addition of an extra module.
Design features:
- Horizontal pan layout comprising well-mixed cells;
- Carefully designed massecuite flow path to avoid flow restrictions;
- Small number of cells of optimal individual cell volumes;
- Separate modules with calandria in each module;
- Low massecuite boiling head; and
- Optional mechanically stirred modules.
Benefits include:
- Excellent massecuite exhaustion, as measured by formal evaluation;
- Significant improvement in raw sugar recovery, as determined by formal evaluation;
- Increased production capacity - about 30% greater than batch pan of comparable volume;
- Strong circulation movement, allowing production of well exhausted massecuite of high dry solid content, with minimal use of balancing water and steam/vapour;
- Minimal operator supervision while maintaining consistent production performance; and
- Rapid and simple emptying, boilout and restart operations.
