摘　　要：研制一种集低温干燥和造粒于一体的集成干燥造粒装置,并给出干燥器主要工艺参数的计算方法.该实验装置用于温度低于60,℃的牛初乳加工,取得了理想的产品.经检测,干燥后牛初乳中的免疫球蛋白的损失率小于冷冻干燥产品,产品粒度均匀、光滑,无需破碎、筛分工序.该装置的研制为热敏性物料的干燥提供了新方法.Drying and granulating integrated device combines low temperature drying techonoly and granulating techonoly.Computation method of the main technical parameters of the dryer were given.This device was used to dry bovine colostrums with the temperature below 60,℃a,nd the ideal product was achieved.The results of tests show that the loss rate of immune globulin in dried bovine colostrum is less than that of the freeze-dried products.Moreovert,he granularity of dried product is uniform and smooth.It dispenses with crushing and screening.This device provides a new method to dry the thermal sensitive material.
