Fluidized bed processing is a relatively novel method for coating metal substrates. A detailed study was carried out into surface property and in micro-structure changes induced by fluidized bed processing. In particular, fluidized bed processing of AA 6082 T6 aluminum alloy components using alumina Al2O3 powder was investigated. Firstly, the build up of Al2O3 films was studied and characterize...

The influence of pretreatment methods like physical, chemical, combined and hybrid treatments on the Turkey berry (Solanum torvum) fruits to enhance water diffusion during drying was assessed due removing a waxy layer peel. Pretreated untreated samples were dried at 70 ?C 4 m/s air flow in fluidized bed dryer. Fruits pretreated with abrasion blanching have lowest time good vitamin C content ret...

Sago is an essential source of starch for some regions in the third and developing world. However, sago processing industry has been producing a large amount waste, untreated waste usually disposed to nearest river. It not only leads environmental problem, but it illegal under Environmental Quality Act 1974. Since still high content, which 58%, can be converted value-added products such as poul...

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...

The mechanism of vibration energy transfer in a vibrating fluidized bed (VFB) is reported in this paper. A series of sensors was employed to simultaneously detect pressure wave propagation signals at different positions at various heights in the fluidized bed. The mechanism of vibration energy transfer in an VFB is found by wave propagation. The pressure wave was produced from a vibrating base ...

Drying plays a crucial role in various industries such as food production, agriculture, Siddha, Ayurveda, and medical fields. To achieve controlled drying conditions, heat pump dryer is considered an effective method, allowing for precise control of parameters like temperature, humidity, air velocity. In this study, was designed constructed to investigate the characteristics Bermuda grass (Cyno...
