A modular drying processor for the development of energy and time efficient combined drying processes was constructed. It allows the serial and/or parallel application of different drying methods such as freeze-, hot-air-, infrared-, contact-, microwave- or vacuum-drying without interruption between the processes. Depending on the drying method precise product structures could be achieved by using the example of carrot cubes. The serial combination of freeze- and microwave vacuum drying shortened the process time about 40% while highest product quality was obtained.
