Quick answer: Coconut sugar absorbs moisture from humid air, so warehouses that store it should monitor both temperature and relative humidity. Use calibrated digital loggers placed at several points, record readings at least daily or continuously, set clear action limits and respond quickly when readings rise. Stable, cool and dry conditions keep sugar free-flowing and protect its shelf life.
Key takeaways – Measure relative humidity as well as temperature. – Place sensors where conditions are worst, not only where it is convenient. – Define action limits and record what was done when they are exceeded.
Why does humidity matter so much?
Coconut sugar keeps small amounts of glucose, fructose and minerals that attract water. If the air in a warehouse is humid, moisture can enter through damaged or open liners and cause clumping. Temperature swings make it worse: warm, humid air can condense on cooler surfaces, including the inside of bags and containers.
What should be monitored?
| Parameter | Why | How |
|---|---|---|
| Relative humidity | Main driver of moisture uptake | Digital hygrometer or data logger |
| Temperature | Affects condensation and product stability | Same logger |
| Temperature swings | Cause condensation | Continuous logging |
| Roof or wall leaks | Direct water risk | Visual checks after rain |
Where should sensors be placed?
- Near external walls and doors, where conditions change most
- At different heights, because warm air rises
- Close to stored sugar, not only in offices
- Away from direct sunlight or heat sources that distort readings
How often should readings be taken?
Continuous data loggers are ideal, recording every few minutes and storing data for review. If manual readings are used, record them at fixed times each day, including the hottest part of the day.
What action limits should be set?
Exact limits depend on climate, building and product, so each warehouse should define its own based on experience and shelf-life data. A practical approach is:
- Define a normal range.
- Define a warning level that triggers checks.
- Define an action level that triggers corrective steps.
What corrective actions help?
- Close doors and reduce unnecessary openings
- Run dehumidifiers or air conditioning
- Improve ventilation where outdoor air is drier
- Move sensitive stock away from walls and doors
- Repair leaks immediately
- Inspect bags for damage and reseal opened liners
How should records be kept?
Records should show date, time, location, readings, who checked and any actions taken. Digital loggers make it easy to keep and export data for audits. Records also help investigate complaints about clumped sugar.
What about tropical warehouses?
In tropical climates, humidity can remain high for long periods, especially during the rainy season. Good building design, pallets off the floor, gaps from walls, sealed liners and fast stock rotation are particularly important.
How does this apply at IMC?
PT Integral Mulia Cipta (IMC Group) stores and ships coconut sugar from Central Java, where the climate is tropical and humid for much of the year. Controlled storage and moisture-barrier packaging, with paper bags and food-grade liners, are essential in this setting.
Frequently asked questions
Why monitor humidity in a sugar warehouse? Because humid air causes coconut sugar to clump.
What equipment is needed? Calibrated digital temperature and humidity loggers.
Where should sensors go? Near walls, doors and stored product, at different heights.
What if humidity is too high? Use dehumidifiers, reduce door openings and check packaging.
