隔板对油茶籽液压制油效率的影响
Effect of different partition plates on the efficiency of oil extraction from Camellia seeds under hydraulic pressing
摘要
Abstract
[Objective]To study the effect of different partition plates on the efficiency of oil extraction from Camellia seeds with different oil content in Guizhou and to evaluate the applicability of hydraulic pressing technology to oil extraction from Camellia seeds in Guizhou.[Methods]Oil content in Camellia seeds from different production areas in Guizhou is detected,and Camellia oleifera seeds from Yuping and Guiyang and Camellia weiningensis seeds from Weining with different oil content are selected as raw materials.Tests of oil extraction by hydraulic pressing are conducted with a non-perforated plate,a perforated plate,and a perforated and carved plate as partition plates to analyze the oil yield,residual oil rate,and oil extraction rate.Screw pressing is used as a control,and a perforated and carved plate is used as the partition plate to conduct the test of oil extraction by hydraulic pressing on Camellia weiningensis seeds.The oil yield,residual oil rate,oil extraction rate,and finished oil production yield are analyzed.[Results]Compared with the non-perforated plate,the perforated plate and the perforated and carved plate improve the oil yield and oil extraction rate and reduce the residual oil rate of the seed cake.In particular,the perforated and carved plate shows a good efficiency of oil extraction from Camellia weiningensis seeds.Specifically,compared with the non-perforated plate,the perforated and carved plate enhances the oil yield by 2.33 percentage points,reduces the residual oil rate by 4.39 percentage points,and increases the oil extraction rate by 4.55 percentage points,up to 92.48%.Additionally,the finished oil production yield of perforated and carved plate pressing increases by 3.4 percentage points,compared to that of screw pressing.[Conclusion]The use of a perforated and carved plate can increase the outflow rate of oil and improve the production efficiency of hydraulic pressing.It is more suitable for Camellia weiningensis seeds from Weining,Guizhou.关键词
