Abstract

Extraction rate of oil from fish muscle with solvent immiscible in water was investigated in the early stage of extraction. It was reported in our previous paper that ratio of extracted oil and removed water was constant through the early stage of extraction independently of time. Therefore, dehydration rate was considered by assuming the extraction of mixture of oil and water was pushed out, and following equation was derived for cubic system by a simple model about dehydration. The emerimental results were agreed well with this equation.<BR>1-R1/3ω=Kω/L√t<BR>This equation may be applied to the extraction of oil because of the mechanism of oil extraction in early stage would be the same mechanism of dehydration. Then, to draw an extraction curve on semi-logarithmic gragh, ln R vs. Kt, following equation was derived.<BR>Kt=3ππ2D/K002(1-R1/3)(1-R1/3)H<BR>This equation was also agreed well with the experirnental results about extraction of oil.
