PURPOSE:To obtain deodorized soybean flour having desired particle size, easily, by removing the skin from soybean, heating and deodorizing the seed leaf, heating until the water-content of the seed leaf reaches a specific level and crushing the dried leaf. CONSTITUTION:A soybean grain is divided into two and the skin is separated from the seed leaf. The skin is discharged from the system by air elutriation and the remaining seed leaf is transferred to a deodorizing apparatus furnished with a screw conveyor which enables the transfer of the seed leaf along a definite direction under kneading in sealed state.The leaf is heated during the kneading and transfer process to a water-content of about 20%. The characteristic odor of fat in the seed leaf is eliminated by the heat-treatment in the deodorizing apparatus. The deodorized and dried seed leaf is sent to a heating apparatus, heated to attain a water-content of about 17-18%, and crushed with a crusher to a desired particle size to obtain the objective soybean flour. |
