Analysis of peat granules drying methods
Abstract
This paper analyzes the main methods of drying peat pellets in a heated drum: with moisture displacement by unheated air, with moisture displacement and partial recirculation of the spent drying agent, and with moisture displacement by unheated air with heat recovery from the spent wet agent. The process of drying peat pellets in a drum using an intense ultra-high frequency (UHF) electromagnetic field with moisture displacement by unheated air is also considered. The main parameters of the convective drying process are assessed with the aim of selecting optimal conditions for its occurrence, allowing for a reduction in energy consumption for obtaining the final product. For the considered methods of drying peat pellets, analytical dependencies are presented for assessing the optimal parameters of the drying agent at equilibrium between the dried material and the drying medium.
