摘要
对油脂脱色工序进行研究,采用两段式脱色方法,即先用再生白土进行预脱色,再生白土添加量为0.7%,除去其中大部分热敏性物质,热敏物质脱除率达到96%;再进行第二步脱色选出最佳脱色条件:白土添加量1.2%,脱色时间30min,搅拌速度250r/min,脱色温度100℃,此条件下得出的脱色油颜色稳定不易返色。
The article aimed to research the oil decoloration process usefully. Used the two-stage bleaching method,the first step was to use renewable clay to pre-bleache,the adding amount of recycled clay was 0.7% ,and remove the most heat-sensitive material ,the removal rate of thermal material was 96% ,then carried out the second step decolorization to select the most best bleaching conditions.the adding amount of clay was 1.2%, bleaching time was 30min,stirring speed was 250r/min,and the bleaching temperature was 100℃. In the end, obtained under these conditions, color was stable and difficult to return color.
