1200T/D菜籽预处理压榨车间工艺设计摘要本课题采用的是传统的油菜籽预处理压榨的工艺，是在传统的高温（125℃～130℃）预榨-浸出制油工艺的基础上进行改造和创新，采用适温（105℃～110℃）预榨-浸出工艺，工序包括清理、调质，轧坯、蒸炒，压榨、以及毛油净化，很多工序已经相当成熟，只是根据不同品种油菜籽的表皮厚薄、水分高低及其质地软硬程度，在各个工序上重视程度不同，比如软化和蒸炒调节其水分和温度,在实际的生产中，适温压榨保留了一部分菜籽粕蛋白的活性，饼粕中蛋白质的有效生物效价较高，从而获得较为理想的菜籽油和菜籽蛋白，适于禽畜的饲养。而压榨后的油进行精炼可以得到二级油的标准。并且，本工艺可以进行连续化，自动化生产，满足了国民对菜籽油的大量需求，再者，该工艺相对较为完善和成熟，在实际应用选择设备时较为容易，不会存在找不到配套设备的问题。本文对预榨浸出工艺各工序进行衡算、设备选型及风网计算。关键词：各种工艺预榨浸出工艺计算选型ITitle1200t/drapeseedcrushingplantpretreatmentprocessdesignAbstractThesubjectisthetraditionalrapeseedbypressingpretreatmentprocess,isinthetraditionalhightemperature(125~130)pre-press-solventextractionprocesson℃℃thebasisofreformandinnovation,andoptimaltemperature(105~110)pre-press-℃℃leachingtechnology,processes,includingcleaning,conditioning,rolling,throwing,steamedfried,pressed,andthepurificationofcrudeoil,manyprocesseshavebeenverymature,andjustundertheskinthicknessofdifferentvarietiesofrapeseed,thelevelandthetextureofsoftwaterhardwarelevel,theimportanceofvariousprocessesondifferentlevels,suchassofteningandsteamedfriedtoadjustitsmoistureandtemperature,intheactualproduction,theoptimumtemperaturepressrapeseedmealproteintoretainaportionoftheactivityoftheproteincakeofaneffectivebiologicalpotencyhighertogainmoreidealrapeseedoilandprotein,suitableforlivestockrearing.Andafterpressingtherefiningoilcanbetwostandards.Moreover,theprocesscanbecontinuousandautomaticproductiontomeetthelargedemandforpeopleontherapeseedoil,Furthermore,theprocessisrelativelyperfectandmature,inthepracticalapplicationofselectedequipmenteasiernotexistcannotfindthematchingequipmentproblems.Inthispaper,pre-pressingextractionprocesstoaccountforallprocesses,equipmentselectionandventilationnetworkcalculation.KeywordsVariousprocessPre-pressingextractionprocessCalculateSelectionII目次绪论...................................................................11工艺说明书...........................................................11.1国内外油菜籽加工工艺...............................................11.2设计方案..........................................................52设计计算书...........................................................82.1物料衡算...........................................................82.2热量恒算...........................................................83设备选型............................................................143.1主要的生产设备选型................................................143.2输送设备的选型....................................................234其他辅助设备........................................................375主要设备清单........................................................37结论................................................................39致谢................................................................40参考文献..............................................................41第1页共47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47页绪...
