摘要:以红枣为原料,进行红枣浆的喷雾干燥研究。在进料速率为8 10r/min,压缩空气压力1atm,风量40m3/h,浓度质量分数8%等条件下,考察红枣的喷雾干燥进气温度对成粉状况的影响。并对不同辅料添加比例时对红枣粉特性——含水量、色差、SEM的影响进行研究。实验结果显示,进气温度在135±5℃时,可获得红枣全粉,且含水量在6%以下。添加辅料后,含水量随着辅料比例的减少逐渐升高,色差随着辅料量的减少逐渐增加,辅料对SEM形态影响不大,红枣颗粒表面生成皮质层,并且成收缩状。
Red jujube spray drying was studied in this paper. The conditions of spray drying were: feed rate 8 - 10rpm, air pressure latm, inlet air flow 40 m3/h, and feed concentration 8% (mass percent). Inlet air temperature and rate of additive to red jujube was investigated. And the properties of jujube powder, i. e. , moisture, color difference, and SEM, were studied with different amount of additives. The results showed that pure jujube powder was obtained at inlet air temperature 135 ± 5℃, and moisture was below 6%. After adding additives, moisture and color difference of the product increased with the decrease of additives. Additives had little impact on SEM. The shrinking of particle surface was showed in SEM.
