High efficiency disperse dryer - an innovative process for drying of solutions, suspensions and pastes in a fluidized bed of inert particles
In this paper, an innovative fluidized bed dryer with inert particles is presented. The system can be used for drying of solutions, suspensions and pastes in order to obtain a powdered product. The experiments were performed in a pilot-scale dryer with a cylindrical column 0.215 m in diamet...

| description | In this paper, an innovative fluidized bed dryer with inert particles is
presented. The system can be used for drying of solutions, suspensions and
pastes in order to obtain a powdered product. The experiments were performed
in a pilot-scale dryer with a cylindrical column 0.215 m in diameter and 1.2
mm height, with glass spheres as inert particles. The material used for
drying was CuSO4 solution. The effects of operating conditions on the dryer
throughput and product quality were investigated. Main performance criteria,
i.e. specific water evaporation rate, specific heat consumption and specific
air consumption, were quantified. Nearly isothermal conditions were found
due to thorough mixing of the particles. The energy efficiency of the dryer
was also assessed. Simple heat and mass balances predicted the dryer
performance quite well. [Project of the Serbian Ministry of Education, Science and Technological Development, Grant no. ON172022] |
