Abstract

Mass transfer between solid and liquid is commonly found in extraction process. Oil extraction from catappa seeds was carried out in the stirred flask using normal hexane as a solvent. The aim of this research is to show a dimensionless equation of a Sherwood number {/} as a function both of Reynolds number {/} and Schimdt number {/}. The experiment was conducted in the room temperature, around 290C, stirring speed 500 rpm, blade diameter 2 cm, and the ratio between the mass of catappa seeds and the volume of solvent was 20 gr/100mL–20 gr/200 mL. The calculation error was 0.072%. Based on the research, it is found that Sh = 0,2166.106 . Re-1,506. Sc1,120.
