fluidized bed drying characteristics of soybeans
the present study investigated the influence of air temperature and velocity on the drying kinetics and specific energy consumption during fluidized bed drying of soybean at 80, 100, 120 and 140ºc and airflow rates of 1.8, 3.1 and 4.5 m s-1. six mathematical models for describing the fluidized bed drying behavior were investigated. the value of the drying rate coefficient (k) increased with inc...

متن کاملExperimental Investigation of the Drying Kinetics of Corn in a Packed and Fluidized Bed
In this paper, experimental data on the drying kinetics of corn in a packed and fluidized bed are presented. Experimental research was conducted on a laboratory apparatus. Corn was used as a material because of its significance in agriculture and the food industry. An analysis of the influence of the operational parameters (the drying medium velocity i. e. the flu...
متن کاملContinuous Fluidized Bed Drying With and Without Internals: Kinetic Model
Spirals as internals are utilized to reduce the axial mixing of solids in fluidized beds, by routing the solids flow in a predetermined route or by localizing the solids mixing. The drying kinetics of continuous fluidized bed with and without internals has been compared and modeled using batch drying kinetics and residence time distribution analysis. The batch drying experiments were conducted ...
متن کاملMixing Behaviors of Wet Granular Materials in Gas Fluidized Beds
The mixing behaviors of dry and wet granular materials in gas fluidized bed systems were investigated computationally using the combined Computational Fluid Dynamics and Discrete Element Method (CFD-DEM). Dry particles were observed to mix fairly rapidly during the fluidization process due to vigorous relative motions between particles induced by the flow of gas. In contrast, due to the presenc...
