Intermittent Drying of Beans in a Spouted Bed
Carioca beans are a highly nutritious grain, in terms of the amount of protein, iron and potassium as well as carbohydrates and fiber and as a source of vitamins. The moisture content of recently picked beans is too high for good preservation and storage, resulting in the need for drying before packaging. In this work, the drying of Carioca beans in a laboratory scale spouted bed under intermit...
متن کاملSustainable hydrogen production via reforming of bio-oil model compounds using a novel spouted bed reactor
Hydrogen produced from renewable energy sources can present significant environmental benefits as an alternative to fossil fuels or as a means for clean power generation via fuel cells. The aqueous fraction of bio oil can be used as a source for hydrogen production, if reformed in the presence of active catalytic materials. Recently, we introduced the concept of the spouted bed reactor for the ...
متن کاملProperties of Spent Active Coke Particles Analysed via Comminution in Spouted Bed
Samples of active coke, fresh and spent after cleaning flue gases from communal waste incinerators, were investigated. The outer layers of both coke particles were separately removed by comminution in a spouted bed. The samples of both active cokes were analysed by means of densities, mercury porosimetry, and adsorption technique. Remaining cores were examined to determine the degree of consump...
متن کاملTime Series Analysis of a Closed-loop Electro-spouted Bed System
Over the past several years our research has focused on the development of classical regression models that describe the disposition process occurring in an electro-spouted bed system. Previous analyses addressed the development of linear regression models that related the chemical plating process to electric current levels, liquid flow rates and bed geometry, i.e. intrinsic engineering paramet...
متن کاملDrying of calcium carbonate in a batch spouted bed dryer: optimization and kinetics modeling
In the present work, the drying of calcium carbonate in a batch spouted bed dryer with inert particles has been investigated experimentally. The effect of several operating parameters including air temperature (90, 100, and 110 ˚C), air velocity (Ums, 1.2 Ums, and 1.5 Ums), and dry solid mass (5, 10, 20 g) has been studied. The Taguchi method has been applied to determine the optimal parameters...
