Experimental 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 کاملfluidized 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 کاملBubbling behavior of a fluidized bed of fine particles caused by vibration-induced air inflow
We demonstrate that a vibration-induced air inflow can cause vigorous bubbling in a bed of fine particles and report the mechanism by which this phenomenon occurs. When convective flow occurs in a powder bed as a result of vibrations, the upper powder layer with a high void ratio moves downward and is compressed. This process forces the air in the powder layer out, which leads to the formation ...
متن کاملFluidized Bed Drying of Fruits and Vegetables: An Overview
The quest for novel technologies in the area of food processing & preservation has led to the application of fluidization technique for enhancing the process capabilities, energy efficiencies and overall quality retention in the final products. However, this paper reviews the various fruits and vegetables dried in the fluidized bed dryer and their retention of sensory attributes in the dried pr...
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 ...
