| 为了降低粕残油，解决平转浸出器油斗内粕末堆积等问题，结合浸出过程合成图，对固定栅板平转浸出器的喷淋和油斗布置提出了一些新的看法。通过分析瞬时前提量，得出混合油前提量的计算方法。同时，分析了浸出器运转过程中所产生的摩擦力矩(功率计算的基础），得出了较为精确的计算公式。实践表明，所设计的平转浸出器应用6年有余，粕残油在0.5%以下，自清式油斗大大减少了设备的清理频次，摩擦力矩公式也被证明是相对精确的。 |

| In order to reduce residual oil in meal and prevent fines accumulation inside the miscella funnel of rotocel extractor, some new ideas about spray and arrangement of miscella funnel were presented according to the combination chart of extraction.The calculation method of miscella amount pumped forward was obtained through the analysis of the instantaneous amount pumped forward.In addition, the friction torque （basis for power calculations）generated during the operation of the extractor was analyzed, and the accurate calculation formula was obtained.Practice has shown that the improved rotocel extractor has been in use for over 6 years, residual oil rate is below 0.5％, the self-cleaning miscella funnel greatly reduces the frequency of equipment cleaning, and the friction torque formula has also been proven to be relatively accurate. |
