速冻薯条加工过程中预干燥工艺的研究

摘要

Pre-drying process was an important part in frozen French fries production line. The operation con-ditions different drying temperature,wind speed,drying time and material quantity per unit area were investigat-ed by single and orthogonal array design methods based on quality of French fries,and their optimum levels were Found to be 75℃,1.6 m/s,60 min,15 kg/m2,respectively. Under the optimized conditions to produce frozen French fries,its product quality was best.%预干燥工序是速冻薯条生产线中的重要一环。本试验研究了不同的预干燥条件（不同的干燥温度、干燥风速、干燥时间及单位面积铺料量）对薯条成品品质的影响，进而得出了最佳的预干燥工艺参数。试验结果表明，干燥温度为75℃、干燥风速为1.6 m/s、单位面积铺料量为15 kg/m2、干燥时间为60 min，在此预干燥工艺条件下生产出来的速冻薯条，其成品的综合品质最好。
