全自动卧式液压压榨机制备核桃油的工艺优化Optimization of preparation of walnut oil by automatic horizontal hydraulic press

Abstract

为了降低全自动卧式液压压榨机制备核桃油的生产成本，采用单因素试验考察了原料颗粒度、原料水分和入榨温度对核桃饼残油率的影响，在此基础上以核桃饼残油率为指标，运用响应面法对全自动卧式液压压榨机制备核桃油的工艺条件进行优化。结果表明：全自动卧式液压压榨机制备核桃油的最佳工艺条件为原料颗粒度120目（0.125 mm）、原料水分1.5%、入榨温度60 ℃，在此条件下核桃饼残油率为13.43%。 In order to reduce the production cost of walnut oil prepared by automatic horizontal hydraulic press, the effects of raw material particle size, raw material moisture and pressing temperature on the residual oil rate of walnut cake were studied by single factor experiment. Then with the residual oil rate of walnut cake as an index, the conditions of preparing walnut oil by the automatic horizontal hydraulic press were optimized using response surface methodology. The results showed that the optimal process conditions of preparing walnut oil by the automatic horizontal hydraulic press were obtained as follows: raw material particle size 120 meshes(0.125 mm), raw material moisture 1.5%, pressing temperature 60 ℃. Under these conditions, the residual oil rate of walnut cake was 13.43%.
