Humidity control and drying for chocolate and confectionery manufacturing

During production, chocolate is highly hygroscopic. If the humidity is too high in your facilities, chocolate can absorb moisture, leading to grainy textures and a rough finish. Excess moisture can also cause chocolate to seize during the melting process, making it difficult to shape.

Furthermore, high humidity can lead to sugar bloom or fat bloom on the surface of chocolate. This unappealing white coating hurts the appearance of your chocolate, making it less desirable to consumers.

Consistent air humidity prevents issues like chocolate bloom, cracking or deformation during manufacture and cooling, so you can deliver quality products week after week.

High humidity causes sugar to absorb moisture, leading to clumping and stickiness. This makes sugar difficult to handle and process, affecting production efficiency.

Moisture absorption can also alter the texture and quality of sugar-based products, resulting in a grainy or uneven consistency. This can increase waste if your output does not live up to your or your customers’ standards.

Additionally, excess moisture can promote microbial growth in sugar products, reducing their shelf-life and potentially endangering consumers.

Using industrial dehumidifiers in chocolate and confectionery manufacturing enables you to dry the air across your production facilities, unlocking numerous benefits:

• Protection from chocolate and sugar bloom on the final products

• Microbial growth prevention throughout your assembly lines and storage areas

• Significantly reduced drying times for your products, raising your efficiency

• Raw materials not sticking together during processing or storage

• Complete condensation control in cooling tunnels

• Protection of sugar, cocoa, dye and flavouring powders from moisture

• Safety of products and packaging during storage and transport to their next destination

Fundamentally, industrial dehumidifiers play a critical role in ensuring the quality of your final products, the productivity of your facilities and the wellbeing of your personnel.

Reliable dehumidification systems prevent moisture absorption and microbial growth in your confectionery products. This noticeably extends their shelf-life through storage into retail, reducing waste and increasing profitability.

The optimal relative humidity (RH) levels for chocolate and confectionery manufacturing are typically between 40% and 50% RH. However, this can vary depending on the type of products you are creating. It is important to note that optimal humidity levels will shift at different stages of the production process.

This range helps prevent moisture absorption and bloom formation, and it ensures the smooth texture and appearance of your final products.

Both condensation and desiccant dehumidifiers can be applied during confectionery manufacturing, with each offering different benefits.

In most circumstances, condensation dehumidifiers can capture moisture from the air in a highly efficient and dependable manner.

When it comes to the production of ice cream, for example, our desiccant dehumidifiers are ideal, as they can effectively dehumidify at temperatures as low as -20ºC. They are also suitable for the pre-dehumidification of sugar-coating pans, chocolate moulding machines and drying chambers.

At Dantherm Group, we engineer and supply both condensation and desiccant models, with stationary and portable versions available to choose from. Speak to our experts for advice on the type of industrial dehumidifier that is best suited for your circumstances.

Yes. Dehumidification improves efficiency by preventing moisture-related damage to your machinery and production lines. This streamlines the manufacturing process, reduces downtime and helps ensure consistent product quality, leading to higher production rates and reduced waste.

Choosing the right dehumidifier for your facilities depends on several factors:

• The size of your rooms or facilities

• Ambient temperature, humidity and climate

• The configuration of your facilities

• The type of products you manufacture

Every facility is unique, which is why we tailor our solutions to your precise specifications. Talk to our consultants for advice in determining the right system for your needs.

We pride ourselves on engineering the most energy-efficient dehumidification systems in the market. Incorporating heat recovery technology and separate air flows for greater adaptability, our high-performance dehumidifiers give you absolute control over the climate in your facilities while keeping energy costs to a minimum.
