Case Study: Cane sugar pan floor improvement- South Africa

A cane sugar mill in South Africa installed SeedMaster-4 as part of a step-by-step improvement program on its batch pan floor. The first installation was made on one A sugar batch pan, where the objective was to improve pan performance, reduce batch time, and produce more consistent crystal quality.

The initial installation was quickly proven successful. With SeedMaster-4 control, the pan achieved a significant improvement in crystallization performance, including approximately 25% shorter batch times and improved crystal quality. Based on this result, the customer decided to install SeedMaster-4 on a second A sugar pan as well. The second installation confirmed the positive experience of the first one. After achieving similarly successful results on the second pan, the factory decided to extend SeedMaster-4 control to the complete batch pan floor. In the final configuration, SeedMaster-4 was installed on all batch pans of the mill, including four strike pans and two seed pans.

Step-by-step implementation

The project was not implemented as a full pan-floor replacement from the beginning. Instead, it developed naturally through operational experience:

Operational Impact

After the complete pan floor upgrade, the mill achieved a major improvement in overall production performance. Within one year, the factory increased mill production by approximately 50%. This improvement was not caused by SeedMaster-4 alone. The factory carried out several upgrades in different areas of the mill during the same period. However, according to the customer, the key part of the overall improvement was the modernization of the pan floor with SeedMaster-4 systems. The reason is straightforward: in many sugar mills, the pan floor can become a major bottleneck. When crystallization capacity is limited, upstream syrup production may be forced to slow down, syrup tanks may fill up, and the mill cannot operate at its full potential. By shortening batch times and improving pan floor stability, SeedMaster-4 helped remove this bottleneck and allowed the rest of the factory to operate more effectively. One customer comment clearly summarized the practical effect of SeedMaster-4 on daily operation: “We know when the SeedMaster is not in use, because our syrup tanks start filling up.” This statement shows that the benefit was not only visible in individual batch data, but also in the overall factory balance. When SeedMaster-4 was operating, the pan floor was able to keep up with syrup production. When it was not in use, the limitation became visible through rising syrup tank levels.

Crystal Quality and Process Stability

In addition to shorter batch times, the customer reported improved crystal quality. This was important because higher production capacity is only valuable if it can be achieved without compromising product quality or downstream operation. SeedMaster-4 improved the crystallization process by maintaining more stable supersaturation conditions during the batch. This supported controlled crystal growth, reduced operator dependency, and made the boiling process more repeatable. As a result, the mill was able to operate its pans more consistently and at a higher effective capacity. The installation on both strike pans and seed pans also helped stabilize the complete crystallization chain. Better seed production supports better strike pan performance, while more consistent strike pan operation improves the overall sugar end balance.

Conclusion

This case demonstrates how SeedMaster-4 can create value not only on an individual vacuum pan, but across an entire sugar mill. The first installation on one A sugar pan delivered approximately 25% shorter batches and improved crystal quality. This result was strong enough for the customer to quickly expand the system first to a second pan, and later to the complete batch pan floor. After SeedMaster-4 was installed on all four strike pans and two seed pans, the mill achieved a major improvement in overall production performance. Although other upgrades were also implemented during the same period, the customer identified the SeedMaster-4 pan floor upgrade as a key factor behind the mill’s approximately 50% production increase within one year. The customer’s observation that syrup tanks begin to fill when SeedMaster-4 is not in use provides a practical and powerful summary of the result: SeedMaster-4 helped remove the pan floor as a production bottleneck and enabled the mill to operate at a significantly higher level.
