Summary Data have been secured on the countercurrent extraction of soybean flakes by trichloroethylene in a laboratory extraction pilot plant having a capacity of about 10 lb. per hour. Feed rates and extraction times departed only slightly from a straight line relationship with the speed of the chain used to move the flakes through the extractor. Over the ranges studied, changes in solvent‐feed ratios had a much greater effect than the extraction time on the amount of oil extracted. Over a practical range of temperatures with the solvent‐feed ratio constant, the residual oil content of the meal showed a straight line relationship with the temperature.
