Summary Data are given which show the effect of the various extraction variables on the extraction of fish meal in both the laboratory and pilot plant. The use of wetting agents, although promising in the laboratory, does not appear to be of much value for pilot plant operation. A higher percentage of the oil components is removed by trichloroethylene under a given set of extracting conditions than with hexane. The mechanism of the extraction is believed to be one of surface‐washing for short extractions, and for longer extractions this washing process is supplemented by diffusion.
