Sugar Manufacturing
Impact of Uncontrolled Humidity
In sugar distilleries, refined sugar is typically transported via belt conveyors to sugar bins or hoppers. At this stage, the sugar is approximately 48°C with a moisture content of about 0.035% of its weight. For optimal packaging, the sugar must be cooled to around 38°C to 40°C. Conventional cooling methods can take 12-36 hours, during which condensation forms on the bin ceiling, leading to lumping of the top layer and a deterioration in sugar quality.
Consequences of High Humidity
● Condensation: Prolonged cooling times lead to condensation on bin ceilings.
Lumping: Condensation causes the top layer of sugar to lump, impacting its quality.
Extended Cooling Time: Conventional methods require significant time, delaying the packaging process.
Additional Effects
● Product Deterioration: Moisture leads to a decline in sugar quality, affecting texture and consistency.
● Inefficiency: Longer cooling times reduce operational efficiency and throughput.
● Quality Control Issues: Maintaining consistent product quality becomes challenging.
Causes of Uncontrolled Humidity
Several factors contribute to high humidity levels in sugar distilleries:
● Water Usage: The presence of large water bodies needed for production.
● Vapor Release: The sucrose extraction process releases a substantial amount of vapor into the air.
● Heat Generation: Small electricity generation units within the factory premises contribute to the overall heat and humidity.
Recommendation
For optimal storage, the relative humidity (RH) in sugar storage areas should be maintained at 20% RH at 24°C (75°F).
Solution
Desiccant Dehumidifiers for Sugar Distilleries
Josem provides desiccant dehumidifiers designed to address moisture issues during the storage and packaging of sugar. These dehumidifiers remove moisture from the air through continuous physical adsorption, preventing condensation and ensuring high-quality sugar.
Key Benefits of Josem Desiccant Dehumidifiers:
● Effective Moisture Control: Capable of maintaining RH as low as 1% or even lower, regardless of ambient conditions.
● Improved Cooling Efficiency: The dry air from the dehumidifier is pre-cooled before being blown into the storage bin, significantly reducing cooling time.
● Quality Assurance: Ensures sugar remains lump-free and maintains its quality during storage and packaging.
Recommended Practices:
● Maintain Low RH: Use desiccant dehumidifiers to keep RH levels at or below 20% to prevent moisture-related issues.
● Pre-Cooled Dry Air: Implement pre-cooled dry air from dehumidifiers to expedite the cooling process and avoid condensation.
● Continuous Monitoring: Regularly monitor RH and temperature levels to ensure they remain within the recommended range.
