ABSTRACT



The post-harvest drying and cooling of cereal grain in silos are becoming an increasingly popular methods of grain preservation for long-term storage. Grain in silos is dried in a thick layer and, in order to reduce costs of this process, an low-cost and reliable method for the measuring of changes in the moisture content in the grain bed is needed. Acting on the assumption that the drying air enthalpy during this process does not change the authors presents in this article a stochastic mathematical model allowing moisture content estimation on the basis of the drying air temperature changes.

Key words: deep bed drying, stochastic model, monitoring of the moisture content.
