摘 要:研究了复凝聚法制备含油微胶囊的工艺过程。以大豆油为囊芯材料,阿拉伯胶与明胶为璧材,研究了溶液p H 值,反应温度,反应时间,壁材浓度,搅拌条件等对微胶囊产品质量的影响。发现搅拌速度对微胶囊的粒径大小和分布影响很大。最佳工艺条件为:明胶与阿拉伯胶质量比为1,浓度都为2 % ,p H 值为4.0～

4.5 ,搅拌速度为1500 r/ min ,反应温度为55 ℃,凝聚时间为15～20min ,固化温度为10 ℃,固化时间60 min。

Abstract: The practical engineering problems that“Pharmaceutical Engineering design ” face are real and complex, how to plant design and preparation technology, GMP, equipment and public works organically combined with research and teaching has become the pharmaceutical in engineering course and research priority.Aiming at the characteristics of the teaching proce, teaching practice, teaching content and teaching methods around, introduced to improve the teaching effectivene of courses made by practice and try to reform, specific measures include: stimulating interest in learning, theory with practice, to strengthen curriculum aement to improve practice effects, and explains the teaching of pharmaceutical engineering design,How cultivat students the quality of engineering ,so that students can link theoretical knowledge and engineering together, to gradually achieve change from students to the pharmaceutical engineers.Keywords: pharmaceutical engineering design;engineering quality;practice;teaching reform

三、A series of microcapsules were prepared by in situ polymerization with poly(urea–formaldehyde)as the shell material and gla beads as the core material.Gla beads were chosen as the core material because their size distribution was narrow and their surface was easily changed to be hydrophobic.The respective effects of initial pH value, concentration of wall material and surfactant, stirring rate on the state of microencapsulation were investigated systematically.The results showed that the surface morphology of the microcapsule depends mainly on the final pH value and stirring rate.A higher final pH value and faster stirring rate helped to prepare a smoother microcapsule.Addition of ammonium chloride was found to be very important in preparing of PUF microcapsules.The involvement of ammonium chloride caused a substantial drop in thepHvalue during reaction and enhanced the deposition of UF nanoparticles onto the surface of microcapsule.
