| 以自制带压力数据采集系统的微型直筒式压榨试验装置，研究了压榨压力、压榨速度和保压时间对蓖麻籽冷态压榨出油率的影响。结果表明：适度缓压和适度重压能实现油料破碎建立必要的出油孔道,并使油路处于持续张开的状态，合理控制保压时间能保障油从榨料孔隙中迁移析出，进而最终协同实现高出油率。综合高效制油和经济可行等因素，优化得到较佳的操作条件为：压榨压力25 MPa、压榨速度2.2 mm/s和保压时间20 min，在此条件下蓖麻籽冷态压榨出油率大于60%。 |
| 英文摘要: |
| Using self-made micro tube press tester with pressure data acquisition system, the effects of pressing pressure, pressing speed and pressing time on the oil yield of cold press of castor seed were studied. The results showed that moderate pressure and stress could make the oilseeds crush to form necessary channels for oil migrating in a continuously open state, and the oil could migrate from the oilseeds pores with a proper pressing time, finally high oil yield could be obtained. Considering the efficient pressing and economically feasible, the optimal operation conditions were obtained as follows: pressing pressure 25 MPa, pressing speed 2.2 mm/s and pressing time 20 min, and the oil yield of cold press of castor seed was higher than 60% under these conditions. |
