Increased safety, productivity and hygiene with dehumidification
For the dairy industry the dry winter climate is preferable as drying processes, conveyors and hygroscopic products absorb less or no humidity from the ambient air. This means processes are faster, uninterrupted and the risk of mold is reduced.
With Munters desiccant dehumidification air as dry as naturally available on winters day can be produced regardless of the season .
Spray drying and fluidized bed drying whey or Infant milk powder
For whey or infant milk powders the capacity enhancement is several added tens of percent and energy consumption is reduced significantly using a desiccant dehumidifier throughout the year.
The dehumidified air supplied to the spray drier is blown through the infant milk or whey powder to evaporate the water, resulting in premium dry powder with an ultralow moisture content. Spray drying with dry air shortens drying times, and is used when dealing with heat-sensitive products.
Munters dehumidified air supplied to the spray tower levels out seasonal humidity fluctuations, so shortening product drying times, conserving energy and maintaining the fine quality of the powdered product
Munters desiccant drying wheels (rotors) have been proven by the Swedish Institute for Food and Biotechnology to have bactericidal and fungicidal properties – an added advantage for food safety.
The dried product often needs to be cooled down. This can apply to products containing fat that can turn rancid. Milk or whey powder can be further dried and cooled in a fluidized bed drier and pneumatically transported using Munters dehumidification to prevent reabsorption of moisture.
- Uniform premium product quality
- Reduced risk of mold and bacteria
- Improved hygiene conditions
- Constant operating conditions
- Shortened drying times
- Increased capacity
- Moisture regain and sticking prevented
- Lower energy consumption
- No product sticking
In a pneumatic conveying system, the contact between the air and conveyed product is very close which means that a dried powders can reabsorb humidity if the conveying air is humid. To prevent this pneumatic conveying systems are equipped with dehumidifiers to keep raw materials fast flowing and free from sticking and caking.
Air containing particles from the food production process are usually filtered before the outlet to the open air. During periods of standstill hygroscopic product in the filter can absorb humidity and clog up the filter. With a Munters dehumidification system the filter is kept dry
