榨油生产线：新型工艺与大型冷榨设备针对双低油菜籽制油方法
双低油菜籽制油新工艺与大型冷榨设备开发，双低油菜籽是我国一种十分重要的优势油料资源，但双低油菜籽制油加工却存在许多问题，主要有：热榨法制油会造成菜油中营养成分损失，饼粕中蛋白质变性而不利于深加工综合利用;冷榨法生产双低菜油，因菜籽脱皮技术没有很好解决，饼粕资源综合利用程度较低。这些问题致使我国双低菜籽的资源优势未能真正转化为经济优势。
Double low rapeseed oil processing technology and large scale cold pressing equipment development, the double low rapeseed is our country a very important advantage of oil resources, but production of double low rapeseed oil processing, there are many problems, mainly: hot pressing method of oil will cause vegetable oil in the loss of nutrients, cake protein denaturation and not conducive to deep processing and comprehensive utilization; cold press production of double low rapeseed oil, rapeseed dehulling technology is not a good solution, cake resources comprehensive utilization degree is low.
这些问题致使我国双低菜籽的资源优势未能真正转化为经济优势。
These problems resulted in China's double low rapeseed resource advantages into economic advantages not really.

The innovative achievements and key technologies of the research are mainly:
1、双低油菜籽低温冷榨工艺研究与大型系统装备开发。该成果通过对双低油菜籽脱皮轧胚、全含油菜籽仁膨化的两次细胞破壁，畅通了油路，膨化料易于入榨。该工艺增加了冷榨机生产能力，使冷榨饼残油降低;采用差速破碎、打筛碾搓、风力提皮工艺，菜籽脱皮率达95%、仁中含皮率≤3%、皮中含仁率≤2%，研制出处理能力≥200吨/天，饼残油14%～16%的大型在线冷却冷榨机，解决无皮菜籽仁螺旋压榨滑膛难题的同时，实现了油料的低温压榨，出饼温度≤75~C。
1, double low rapeseed research of cold pressing technology and large system equipment development. The results by of double low rapeseed dehulling flaking, with rape seed puffed twice breaking cell wall, smooth oil, extruded feed easily into the juice. The process increases the production capacity of cold pressing machine, reduce the cold pressing cake oil residue; by differential speed crushing, screen rolling, the wind-driven leather craft, rapeseed dehulling rate reached 95%, kernel with peel rate less than or equal to 3%, skin contains kernel rate is less than or equal to 2% of developed processing capacity is more than or equal to 200 tons / day, cake oil residue 14% ~ 16% of large on-line cooling cold pressing machine to solve no skin rapeseed dehulled spiral press smoothbore problem at the same time, the oil low temperature pressing, cake temperature is less than or equal to 75~C.
低温菜籽饼粕制备先进蛋白联产多糖研究。该成果以低温冷榨菜籽粕为原料，建立了低浓度碱液浸溶蛋白、结合膜孔径梯度串联超滤制备高品质菜籽蛋白联产多糖的新工艺，实现菜籽蛋白联产多糖的有效分离，碱用量(3‰)明显低于常规工艺(7%)，降低了能耗。在菜籽浓缩蛋白生产工艺中，选用盘式干燥器对物料进行干燥脱溶，双效长管蒸发器对浸提液进行浓缩回收溶剂的工艺方案，环保效益与可持续生产优势明显。
Study on Preparation of Polysaccharides from rapeseed meal for low quality protein production. The results by cold pressing rapeseed meal as raw materials established low concentration of alkali leaching protein, combined with membrane pore size gradient series ultrafiltration preparation new process for production of high quality rapeseed protein polysaccharide, to realize the production of rapeseed protein polysaccharide, separation, alkali dosage (3%) was significantly lower than that of the conventional process (7%), reduces the energy consumption. In the production process of rapeseed protein concentrate, selection of disc dryer of materials for dry stripping, double long tube evaporator condensed solvent recovery process scheme of the leaching solution and obvious environmental benefits and sustainable production advantage.
