中文摘要:

為了降低全自動臥式液壓壓榨機制備核桃油的生產(chǎn)成本，采用單因素試驗考察了原料顆粒度、原料水分和入榨溫度對核桃餅殘油率的影響，在此基礎(chǔ)上以核桃餅殘油率為指標，運用響應(yīng)面法對全自動臥式液壓壓榨機制備核桃油的工藝條件進行優(yōu)化。結(jié)果表明：全自動臥式液壓壓榨機制備核桃油的優(yōu)秀工藝條件為原料顆粒度120目（0.125mm）、原料水分1.5%、入榨溫度60℃，在此條件下核桃餅殘油率為13.43%。

英文摘要:

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%.
