2012届毕业生毕业设计说明书题目:100T/D亚麻籽预榨饼浸出车间工艺设计院系名称：粮油食品学院专业班级：食工F0808班学生姓名：曹富金学号：200848060909指导教师：张振山教师职称：讲师2012年5月15日1摘要亚麻籽含油达到42%左右，油中不饱和脂肪酸占其脂肪酸90%以上，其中，ω-3脂肪酸含量高达49%，比其它油用作物含量高7倍至50倍。所以，亚麻籽油具有预防冠心病、脑血管病、降低胆固醇、抗血栓、降血压、提高动脉系统柔性的功能，极具开发价值。本设计采用浸出法从亚麻籽预榨饼中提取剩余油脂，并根据亚麻籽油不饱和脂肪酸含量高的特点，采用全负压蒸发工艺，减少亚麻籽油的氧化和降低反式脂肪酸的生成，并能有效去除亚麻籽中的毒性物质—氰苷，提高亚麻籽粕的使用范围。关键词：亚麻籽亚麻籽油预榨浸出氰苷亚麻酸TitleTheworkshopdesignof100tons/dayofflaxseedbypre-pressleachingAbstractTheoilinflaxseedreachesabout42%,andtheunsaturatedfattyacidinfattyacidsoftheoilismorethan90%,amongthem,theω—threefattyacidreachesashighas49%,7to50timeshigherthanothercropsoil.So,flaxseedoilhasthefunctionsofpreventionofcoronaryheartdisease,cerebrovasculardisease,lowercholesterollevels,antithrombotic,fallingbloodpressure,andimprovingthefunctionoftheflexibilityofarterysystem,whichhashighlydevelopmentvalue.Thisdesignusestheleachinglawtoextractresidualoilfrompre-pressflaxseedbread.Accordingtothecharacteristicthattheunsaturatedfattyacidcontentedishighinflaxseedoil,evaporationisatthewholenegativepressuretoreduceflaxseedoiloxidationandreducetransfatformation.Inaddition,thismethodcaneffectivelyremovethetoxicsubstances—cyanogenglycoside,andimprovethescopeofapplicationofflaxseedmeal.KeywordsFlaxseedFlaxseedoilPre-pressleachingCyanogenglycosideLinolenicacid目录1绪论............................................................１2设计原则与依据..................................................２2.1设计原则......................................................２2.2设计依据......................................................２3工艺流程及工艺说明..............................................２3.1工艺流程......................................................２3.2工艺说明......................................................３4化工设计计算....................................................６4.1物料平衡计算..................................................６4.2热量平衡计算..................................................９4.3设备选型与计算..............................................１７4.3.6其他设备的计算设计........................................６８4.4设备清单（附录A、B）.......................................６８4.5消耗指标....................................................６８4.5.1蒸汽消耗...................................................６８4.5.2.冷却水消耗................................................６８4.5.3电力消耗...................................................６９4.5.4溶剂消耗...................................................６９5结束语......................................................７０参考文献.........................................................７２附录A：设备一览表...............................................７３附录B：阀门一览表...............................................７６第１页共87页编号：时间：2021年x月x日书山有路勤为径，学海无涯苦作舟页码：第１页共87页1绪论工业用亚麻籽油。亚麻籽含油率为36%-45%。精炼后的油脂外观呈淡黄色、透明、液状，具亚麻籽固有的气味。相对密度0.926-0.6365，折光率1.4785-1.4840，碘值175以上，皂化物188-...
