Performance evaluation of industrial scale fluidized bed paddy dryer
Field investigation on industrial scale fluidized bed paddy drying in a processing plant of Padiberas Nasional Berhad (BERNAS) was carried out to asses drying characteristics, energy consumption and final quality of product during two paddy harvesting seasons. For the first season (August-September)...
