中文摘要: 研究速溶豆粉的最佳喷雾干燥工艺条件，以大豆为原料对速溶豆粉喷雾干燥工艺进行优化研究。以速溶豆粉溶解度和出粉率为指标，对进料浓度、雾化转速、进风温度和进料流量4个因素根据Box-Behnken中心组合试验设计原理进行响应面分析。结果表明：速溶豆粉喷雾干燥工艺的最优条件为进料浓度16%、雾化转速300 r/s、进风温度180℃、进料流量1.2 L/h，在此条件下溶解度为87.33%，出粉率为47.42%。此条件下喷雾干燥效果最佳。
Abstract:Choice of drying conditions affects the efficiency of spray-drying soybean powder.Therefore，the optimum conditions for spray drying instant soybean powder were studied using soybean as raw material.Using solubility and yield as indicators，response surface analysis was carried out on feeding concentration，atomization speed，inlet air temperature and inlet flow rate according to the design principle of the Box-Behnken center combination test.The results showed that the optimal conditions for the spray drying of instant soybean powder were a feed concentration of 16%，atomization speed of 300 r/s，air inlet temperature of 180 ℃，feed flow rate of 1.2 L/h，solubility of 87.33% and powder yield of 47.42%.Under these conditions，spray drying was most efficient.
