Product Drying

The most common method for product drying is to introduce hot air, thus evaporating the moisture contained within the product. However this is not ideal as the increase in heat and humidity increases the risk of mould and fungus growth.

This in turn can cause corrosion to machinery and the extra heat can damage the product being dried. By using Munters dehumifiers the conditions can be kept constant to prevent these destructive conditions from occuring.

Product drying processes such as spray drying and fluid-bed systems can be significantly optimized using Munters energy efficient and highly hygienic dehumidification solutions.

Drying of products e.g. sausage, fruit and cheese requires a controlled humidity level to avoid growth of microorganisms and to ensure reproducible drying cycles year-round.

Avoiding mould and fungus with dehumidification

The most common method for product drying is to introduce hot air, thus evaporating the moisture contained within the product. However, this is not ideal as the increase in heat and humidity increases the risk of mould and fungus growth. Raised humidity levels can also cause corrosion to machinery and the extra heat can damage the product being dried. By using Munters dehumidifiers, the conditions can be kept constant to prevent these destructive conditions from occurring.

Spray drying and fluid-bed systems

For demanding processes, such as drying of milk powder, coffee, yeast, etc. in spray towers and fluid bed systems, hygiene and energy consumption are major issues.

Controlling the humidity level using Munters dehumidifiers ensures constant conditions around the year and provides an improved hygienic environment without growth of micro-organisms.

During the adsorption process, the air passing through the specially designed Quantum™ rotor is dehumidified by up to 14 g/kg whilst also being heated, reducing the need for a post-heater in the process air.

Benefits:

  • Faster drying processes in spray towers, fluid-bed systems and during coating, providing increased production capacity
  • Munters' unique, bactericidal certified Quantum™ rotor with high DeltaX
  • Energy savings up to 25% in spray tower drying thanks to elimination of pre-cooling
  • Improved hygiene, through the elimination of wet surfaces

 

Health, Safety and Hygiene

Munters rotors are subject to continuous development. Independent tests undertaken by the Swedish Institute for Food and Biotechnology (SIK) have demonstrated that Munters rotors have beneficial bactericidal and fungicidal properties.
