The instantaneous energy efficiency is useful for the real-time (dynamic) optimization of the drying process conditions, for example in batch dryers. Maximizing η E (t) will eventually lead to better sustainability of the drying process. In eqn (2)–(5), the energy efficiency is expressed as a dimensionless value ranging from 0 to 1, indicating how close the
