Intermittent Drying of Porous Materials: A Review
Hygroscopic materials can suffer variations in water content and temperature according to ambient air conditions. In the case of agricultural products, control the moisture and temperature is of paramount importance for the conservation of their quality and to avoid losses. In this context, the drying is one of the most widely used methods for this purpose. Various drying techniques are reported in the literature,in order to increasingly improve the final product quality and saving energy used. The purpose of this paper is to discuss and analyze the latest advances in intermittent drying research from the standpoint of quality after-drying product and energy efficiency. The most applied modeling techniques are highlighted and considerations for its use are shown.
