| Abstract: | 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. |
