Humidity Control at The Chocolate Academy, Dubai

The Chocolate Academy´s centres are, all over the world, known to teach and train artisans and professionals who want to improve their working skills in chocolate and learn more about new trends, techniques and recipes. The Chocolate Academy in Dubai, UAE, the first in the Middle East and Africa, soon became the number one place to exchange knowledge about this divine delicacy in the region.

Avoid damage on the chocolate and climate challenges

The ideal temperature for storing chocolate is between 17 and 22 °C and it is important to keep the temperature consistent. Chocolate must also be protected against humidity.

As a general principle, the maximum relative humidity in the warehouse should be 70%. Storage of chocolate products on the floors or against walls should be strictly avoided because this greatly increases the risk of absorption of humidity.
Without proper storage and the right humidity, chocolate soon lose its shininess and can either sugar bloom or fat bloom, both conditions are caused by moisture.
In sugar bloom, condensation causes the sugar to absorb the moisture and dissolve. When the moisture evaporates, the sugar forms larger crystals, leaving a dusty layer and the chocolate suddenly feels dry and does not melt to the touch. Fat bloom happens if the chocolate gets too warm. The cocoa butter melts and then re-solidifies, leaving those grey streaks.
Both these types of blooms happen when chocolate is stored improperly.

In addition, Dubai weather is characterised by a tropical desert climate with hot, sunny conditions and near coastal areas humidity averages between 50% and 60%.
In the summer, the weather in Dubai is very hot and humid, with humidity averaging over 90%. This hot desert climate has its challenges for businesses like The Chocolate Academy.

In the spring of 2016, the cold storage room at The Chocolate Academy encountered water condensation, especially on finished products.
As a result, they could no longer store the products there and had difficulties where to store it instead.

Creating the perfect conditions

Our salesperson from Munters Dubai office made a visit to The Chocolate Academy and soon realized that something had to be done to control the humidity in the storage.

By installing a ComDry 170L, the problem was eliminated and the production could get going again.

“The problem is now solved! The dehumidifier is very reliable, stable and exceeds our expectation” explains Philippe Marand, Head of The Chocolate Academy.

The ComDry series is a range of desiccant dehumidifiers with high reliability and low energy consumption. The air-cooled condenser cools the wet reactivation air below its dew point the moisture as condensate. The resulting water droplets are collected in a drip tray and pumped away with a built in drainage pump.

The Chocolate Academy can now continue to run its courses and train people without any interruptions or damaged chocolate creations.
