Optimizing industrial drying and cooling processes can result in significant energy savings. One effective method is recirculating the exhaust air from the cooling section back to the dryer’s air inlet.
– The cooler exhaust air, typically at 50–60 °C, still contains valuable thermal energy.
– By reusing this air, energy savings of 10–15% can be achieved.
– This reduces the need for fresh heated air and lowers operational costs.
Below is an image of the fluid bed dryer/cooler, with the dryer section (insulated) and cooling section, both equal in size.
This approach supports sustainable process design and is increasingly relevant in energy-conscious industries.
