In a previous paper, some experimental results were shown relating to the adaptabiliuy of liquid butane as an extraction solvent for soybean extraction, the extraction condition and the quality of the products. The present study has been done in order to confirm these results in a series of bench scale experimentation under increased pressure using an extractor of about 1015kg charge of soybean flakes per batch. The results of the present study are as follows : 1. The soybean meals of residual oil content of about 1% are obtained by extracting soybean flakes of about 0.4mm thickness for 2 hours at 40°C. 2. Since the solvent of the meals is easily removed at a slightly elevated temperature (5060°C), the meals can be completely freed from the solvent without causing any denaturation of the protein in the meals. 3. Butane extracted oil is light-colored and has a low acid value and lecithin content, so that the oil is refined easily with only a smaller loss and the deodorized oil has a good flavor and a good stability in the A.O.M. test.
