为了提高膨化颗粒饲料烘干机的性能,研制了一台小型的双层床面振动流化床烘干机,并对膨化颗粒饲料进行了烘干实验。结果表明,在相同的工艺条件下,与现时正广泛使用的环流网带式烘干机相比较,显示出烘干时间缩短、单位床面面积产量提高、烘干质量好（颗粒水分不均匀度在2%以下）、烘干能耗降低（排放尾风温度可降至43℃）等特点,表明双层振动流化床具有较好的开发和应用价值。以上述小型机的实验结果为基础,设计了处理量为6t/h的双层振动流化床烘干机的结构方案,其单层床面面积约13.6m2,主机质量约10t,风机总功率约37kW,与相同处理量的网带式烘干机相比较,其制造成本和运行成本都将有较大的降低。...

A small double-layer vibration fluidized bed dryer was made in order to dry the puffed pellet feed effectively. Compared with the recent belt type dryer widely used under the same technological conditions, the drying time was shortened, the capacity per unit area was improved, the feed had a more uniform moisture （non-uniformity below 2 %）, and the drying energy consumption was reduced（the emission tail wind temperature was reduced to 43℃ ）. It＇s indicated that the double layer vibrating fluidized bed had good development and application ...
