Exergic analysis of the installation for controlled dehydration of fine particulate products

Abstract

An installation is designed for dehydration of fine-particulate bulk products in the active hydrodynamic mode. A thermal system for heat-mass transfer during rapeseed dehydration in the active hydrodynamic mode is assessed for thermodynamic efficiency. Diagrams of thermal and exergy balance for heat-mass transfer processes are presented and heat exchange and exergy analysis are performed. Exergy loss by rapeseed dehumidification are calculated The research results show that the greatest loss of exergy occurs due to irreversibility of dehydration processes during the phase transformation, as well as due to the pressure drop in the device.
