Confectionery Industry Dehumidification Solutions

In the Confectionery industry, the quality of the finished product is paramount. Close control of air humidity during the various manufacturing processes is considered essential to maintaining high standards.

Chocolate
Fat blooming and sugar blooming are two common problems when manufacturing and storing chocolate. Both kinds of blooming can occur a few hours after production, and during storage if the ambient air is too humid. The relative humidity (RH) should not exceed 60% during production and storage. Using dry air when cooling chocolate products in cooling tunnels prevents condensation from forming on products and the tunnel. This enhances hygiene levels and products do not become sticky or stick to the conveyor belt.

Sugar coating
It is necessary to maintain control over the ambient humidity when sugar-coating products. Quality is impaired if the ambient humidity is too high, and products readily stick to one another. During the damp season, the humidity also means that the drying time – and hence also the coating time – is extended. Dehumidification ensures that the same drying time and quality are applicable all year round.

Package
Boxes and stacking trays become stuck on the conveyor belt in the packaging machines if they are damp. The packaging process can be improved by using dry air as this ensures that products do not become stuck on machinery or wrappings.

Sugar
Sugar becomes sticky or even dissolves if the ambient humidity is too high. When storing sugar loose or in sacks it is therefore a good idea to control the ambient humidity on the storage premises. Sugar silos should be fed with dry air to protect the head space from condensation.

FAQ

What is a Desiccant Dehumidifier?

A desiccant dehumidifier utilizes a desiccant material (such as silica gel) to absorb moisture from the air. It operates by passing moist air over the desiccant, which adsorbs the water vapor, leaving the air dry. This method is effective in various applications where precise control over humidity levels is crucial.

What is the most efficient method of dehumidification?

Desiccant dehumidification is often considered more effective than other methods like refrigeration-based dehumidifiers (condensers). It excels in environments where low humidity levels are required, offering precise control and efficiency even at low temperatures.

What is dehumidification in the food industry?

In the food industry, dehumidification is essential for maintaining product quality and safety. It prevents moisture-related issues such as mold growth, product sticking, and degradation. Desiccant dehumidifiers are particularly effective in food processing environments where strict humidity control is necessary to ensure product integrity.

Does baking powder dehumidify?

Baking powder is not a dehumidifier. It is a leavening agent used in baking to create gas bubbles that make dough rise. Dehumidification requires specialized equipment like desiccant dehumidifiers that can actively remove moisture from the air, ensuring optimal humidity levels in controlled environments.
