Does extraction screw speed affect oil extraction yield from castor seeds?

To achieve that, the effects of extraction screw speed (30, 60 and 90 rpm) and temperature (120, 140, 160 and 200 ¡ãC) on oil extraction yield from castor seeds, extraction energy and extraction time were studied. The results indicate that, the highest value of decreasing of oil extraction yield

How much oil does a screw press produce?

The results indicate that the maximum oil production is about 40.84% by the screw press which is equivalent to 83.41% by mass fraction of oil in seeds in comparison percentage oil 48.96% in seeds obtained at an engine speed of 30 rpm and preheating temperature of 200 ¡ãC. These results agreed with those obtained by Raja et al. (2011).

How does screw speed affect oil extraction yield?

The results indicate that the oil extraction yield decreases with increasing screw speed and decreasing temperature. It could be seen that the oil yield decreased from 37.66 to 31.13, 32.17 to 31.88, 39.24 to 32.59 and 40.85 to 33.20 % when the screw speed increased from 30 to 90 rpm, respectively, for 120, 140, 160 and 200 ¡ãC.
