| Abstract: |
| 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. |
