蒸馏法提取橙皮精油装置改革与工艺研究

Study on installation reform and technology for orange peel essence oil extraction with water vapor distillation

改革传统蒸馏法将橙皮直接浸于水中,造成提取率低的工艺,设计并制作了改革提取橙皮香精油的蒸馏塔,通过正交试验确定了橙皮精油提取工艺条件。结果表明,提取时间、橙子存放时间、添加剂用量和橙皮破碎度对提取均有影响;优化的提取工艺为:提取时间120 min、橙子存放时间约30 d、NaCl添加量7.5 g、橙皮破碎度10×10。

Reformed the traditional technology to the essential oil extraction, which put the orange peel direct into the water and make for orange peel essential oil extraction with low yield. Designed and made the distilling tower for the orange peel essential oil extraction. The proper condition was determined by the orthogonal experiment. Several elements affect the extraction, including the extraction time, orange preserve time, amount of additional agents and broke extant of the degree of orange peel fragmentation. Optimal extraction process were as follows： extraction time 120 min, orange leave time was 30 d, NaCl addition 7.5 g and size of orange peel 10×10.
