2016届毕业生 毕业设计说明书 题 目: 500吨/天菜籽预处理预压榨车间工艺设计 院系名称： 粮油食品学院 专业班级： 食工P1202班 学生姓名： 蔡雪月 学 号： 201211010524 指导教师： 张振山 教师职称： 讲师 2016年 5 月 1 日 毕 业 设 计 中 文 摘 要 摘 要 油菜籽是世界上最重要的油料作物之一，是仅次于大豆和棕榈的排名第三的植物油料。在我国食用植物油消费中，菜籽油约占总量的35%，菜籽饼粕约占我国植物饼粕消费量的25%，油菜生产对保证我国食用植物油脂和饲用蛋白质的有效供给,促进养殖业和加工业发展等诸方面均有重要影响。目前，菜籽制油的工艺有蒸炒压榨工艺、预榨浸出工艺、膨化浸出工艺等。本次设计是在油菜籽传统制油工艺的基础上，对蒸炒压榨工艺进行进一步的改进和创新，采用先进的卧式蒸炒锅对油菜籽坯片蒸炒，再进一步压榨。采用先进的卧式蒸炒锅可以节省相关的输送设备，占用车间空间更小，使车间设备布置更加紧凑合理。并且在电力、蒸气、溶剂、水消耗量上可以有大幅度的减少。采用螺旋榨油机压榨后的榨饼结构紧凑，压榨排渣量少，榨饼含油率较少，经浸出后粕的残油较低，且提高了生产了效率。此工艺的这些优点使得其在未来的几年里都会有广阔的发展前景。 关键字：油菜籽 预处理 蒸炒 压榨 毕 业 设 计 外 文 摘 要 Title Research on Designing of 500T/D Pretreatment Press Factory for rapeseed Abstract Rapeseed is one of the most important oil crops in the world, it is the third oil plant only next to soybean and palm oil. In edible vegetable oil consumption in China, the rapeseed oil accounts for about 35% of the total, rapeseed meal accounted for about 25% of the plant cake consumption in our country. To ensure the effective supply of rapeseed production of edible vegetable oil and protein feed consumption of our country, promote the development of aquaculture and processing and other aspects have important effects. The current technology of rapeseed oil have pressure technology、pre-pressing extraction process、puffed leaching process. The design is on the basis of the traditional system of rapeseed oil process, to evaporate and squeezing process for further improvement and innovation, using advanced on rapeseed billet horizontal steam frying pan steaming and frying, further squeezing . Advanced horizontal steam frying pan can save related transportation equipment, take up a smaller workshop space, make workshop equipment layout more compact and reasonable. And on the power, steam, solven
