Today many industries now use the dryer as a part of grain-drying process even during wet and dry seasons. This helps in reducing spoilage and wastage of paddy. Mostly the available industrial dryers are expensive to purchase and to maintain its smooth functioning. This study therefore is a step to design a simple Plug flow fluidized dryer that can lead to introduce small scale dryers to paddy process industry. The Plug flow fluidized bed dryers are designed and fabricated in this study consists of the drying chamber, hot air distributer plate, hot air inlet and exit system, paddy entry and exit system, fluidization chamber unit with temperature control unit and the centrifugal fan. The evaluation of dryer is based on drying time and reduction in moisture content and outlet temperature of paddy on quality parameters. Dryer dimensions are very important to analyze heat and mass transfer analysis of the Plug flow fluidized bed drying process of paddy grains. It was found d that heat and mass transfer properties of paddy grains in fluidized bed dryer was decreases as the time of drying passes and very rapid at the start of drying. The model present here predicts about dryer dimensions along safe zone of rough rice moisture content with other parameters. Simulation results show a good agreement between the simulation model and the existing simulation models

Fluidized Bed Drying

This artical also discusses about demostration of fluidized bed dryer with principle and application and other processing. This has lead to development of thechnology, process and equipments which not only reduce time but also increasing the output. A Fluidized bed dryer significantely reduce drying time, compared with vaccum dryer or tray dryer. In the pharmacutical industry, fluidized bed dryer are typically used for pellets drying, coating and granulation. Fluidized bed drying are very well known to yield high heat and mass transfer and hence adopted to many industrial drying process particularly pharmacy product. In this paper we show construction, working of the fluidized bed dryer. It work on the drying principle. It has several advantages and disadvantages.
