油茶籽脱壳机的研制与应用

采用挤压和碾磨原理以及风筛复合分离原理设计开发出了油茶籽脱壳机。油茶籽含水率和辊筒线速度是影响脱壳分离效果的主要因素。适宜的脱壳工艺条件为油茶籽含水率5%～20%，辊筒线速度8.90～10.00 m/s，在此工艺条件下，油茶籽脱壳率≥98.5%，仁中含壳≤4%、壳中含仁≤1%。油茶籽脱壳机成功投入了生产实践应用，获得了质量优良的油茶籽油和脱壳油茶籽饼粕，提高了油茶籽加工的经济效益。

Research and application of dehulling machine for camellia oleosa seed

Dehulling machine for camellia oleosa seed with a dehulling principle of extrusion and mill and a separating principle of sifting and wind was designed and manufactured. The water content and linear velocity of roller are the most significant factors affecting the results of dehulling and separating camellia oleosa seed. The fitting dehulling conditions are confirmed: water content 5%~20%, linear velocity of roller 8.90~10.00 m/s. Under the conditions mentioned above, dehulling rate is more than 98.5%, the content of kernels contained in hull is less than 4%, the content of hulls contained in kernel is less than 1%. The dehulling machine was put to use successfully . Camellia oleosa seed oil and dehulling camellia oleosa seed cake with high quality were obtained, which increased processing value of camellia oleosa seed.
