摘　　要：试验利用实验室自制的猪皮胶原多肽螯合钙原液进行喷雾干燥,研究喷雾干燥过程中不同种类的助干剂、入风温度、入料速度、固形物含量等因素对喷雾干燥产品得率的影响。设计单因素试验和正交试验对喷雾干燥工艺条件进行优化,确定最优喷雾工艺为:选择麦芽糊精作为助干剂、入风温度180℃、入料速度1200 m L/h、固形物含量20 g/100 m L,该条件下喷雾干燥产品得率达到64.20%。对试验制备的胶原多肽螯合钙粉末进行傅立叶红外光谱定性检测,发现螯合前后胶原的化学结构发生变化,确定有螯合物生成。This experiment use the laboratory independent produced collagen polypeptide chelated calcium liquid as raw materials and take the spray drying product yield as index to study the effect of different drying aids,inlet air temperature,feeding rate,solids content on spray drying.Optimize this process by single factor test and orthogonal experiment design and get the optimal process parameters：use the maltodextrin as drying aids,the inlet air temperature at 180 ℃,feeding rate at 1200 m L/h,solids content at 20 g/100 m L.The Fourier transform infrared qualitative detection showed the collagen polypeptide chelated calcium powder was changed in chemical structure and chelate generated.
