滁菊蜂花粉喷雾干燥工艺研究

以滁菊蜂花粉为研究对象,在对蜂花粉破壁工艺进行比较研究的基础上,以出粉率、含水量、堆积密度及溶解时间为指标,通过单因素和正交实验对蜂花粉喷雾干燥工艺进行优化。实验结果表明胶体磨破壁效果较好,破壁粒径可达0.09μm。滁菊蜂花粉最佳喷雾干燥工艺条件:料液比为1∶15(g/mL),进料流量为200mL/h,进料温度为200℃,麦芽糊精的加入量为10%。该条件可以获得最优喷雾干燥产品出粉率为39.8%,含水量为3.9%,堆积密度为0.37g/mL,溶解时间为42s。 

Study on Chu-ju bee pollen spray drying technology

Chu-ju bee pollen was used as raw material. Taking the flour extraction, moisture content, bulk density and dissolved time as index, the spray drying processes had been optimized using single factor investigations and orthogonal experiments based on the comparative study of the bee pollen broken conditions. The diameter was 0.09μm with broken by the colloid mill. The optimal bee pollen spray drying processes parameters were solid-liquid ratio 1∶15 (g/mL) , feed flow rate 200mL/h, inlet air temperature 200℃, and malt dextrin addition amount 10%. Under the optimum spray drying conditions, the flour extraction of product was 39.8%, the moisture content was 3.9%, the bulk density was 0.37g/mL, and the dissolution time was 42s.
