摘　　要：以醪液和麸皮、玉米皮的混合物为研究对象,利用吸附流化床干燥技术考察其干燥情况.初步研究了温度、混合比、料层高度及吸附剂颗粒粒度等的变化对干燥速率的影响,确定了吸附流化床干燥技术加工处理醪液的可行有效的干燥工艺参数.实验表明,吸附流化床干燥技术加工处理醪液,采用吸附剂和醪液的加热温度80～90℃,混合比0.8,吸附剂颗粒粒度0.63～0.8,mm,床层高度100mm,可获取很好的干燥效果;可以为组织大规模生产提供设计依据和参考,证明了利用醪液的干燥技术加工饲料是一种资源再利用的有效方法.The wheat and corn bran and yeasts water mixture was regarded as the research object, and absorption-fluidized bed drying technology was adopted to study its drying characteristic. Heating temperature, mixing ratio, bed height and particle size were analysed as variables to processing production by absorption-fluidized bed drying technology. Experiments show that heating temperature is 80-90℃, mixing ratio is 0.8, bed height is 100mm, and particle size is 0.63-0.8mm for tile process can get good drying effect and provide design basis and reference for large-scale production. Using fluidized drying technology to process feed is an effective method in the reuse of resource.
