Simulation of a Vibrated Fluidised Bed Dryer for Solids Containing a Multicomponent Moisture
The drying of solids in a continuously worked vibrated fluidised bed dryer is studied by simulations. A model considering the drying of a thin layer of particles wetted with a multicomponent mixture is developed. Particles are assumed well mixed in the direction of the airflow and only the longitudinal changes of liquid content, liquid composition and particle temperature are considered. Intera...
متن کاملModeling and Control of a Fluidised Bed Dryer
In this paper, the modelling and control of the moisture content of the particles in a batch Fluidised bed dryer are studied. First, a lumped mechanistic model is developed to describe the heat and mass transfer between solid, gas and bubble phases and experimental validation shows that the model can be used to predict the particle moisture content and temperature profiles during the drying pro...
متن کاملdesign, development and evaluation of a continuous plug flow fluidized bed dryer
in this study, a laboratory scale continuous plug flow fluidized bed dryer was designed and constructed. a backward-curved centrifugal fan with a 4 kw electromotor was selected based on the maximum pressure drop in the minimum fluidization state and the ability to produce the velocity required for fluidization of the most granular agricultural materials. the fluidization chamber was a rectangul...
متن کاملdrying rough rice in a fluidized bed dryer
the objective of this study was to examine the effects of the fluidized-bed drying me-thod on the final quality of two varieties of iranian rice, medium- and long grain. the re-sults were compared to that of paddy drying using a traditional method. rough rice was treated in the fluidized bed drier at 140ºc for 2 minutes. similar samples were dried for 8-10 hrs by the traditional method. dried s...
متن کاملCFD Simulation and Optimization of Factors Affecting the Performance of a Fluidized Bed Dryer
Computational Fluid Dynamics (CFD) is a computational technology that enables researchers to study the dynamics of things that flow. By using CFD, it is possible to build a computational model that represents a system under study. It not only predicts fluid flow behavior, but also the transfer of heat, mass, phase change, chemical reaction, mechanical movement, and stress or deformation of ...
