Waste Heat Recovery in Industrial Drying Processes

The overall objective of the DRYficiency project is to lead energy-intensive sectors of the European manufacturing industry to high energy efficiency and a reduction of fossil carbon emissions by means of waste heat recovery. Technically and economically viable solutions for upgrading idle waste heat streams to process heat streams at higher temperature levels up to 180 °C will be elaborated. The key elements are two high temperature vapour compression heat pumps (closed loop for air drying /open loop for steam drying). The solution will be demonstrated and validated under real production conditions in operational industrial drying processes in three leading European manufacturing companies from the pet food, food and brick industries.
