(57) [Summary] [Problem] To molt and dehypocotyl a swollen soybean without damaging cotyledons, efficiently separate a mixture of hypocotyl and seed coat obtained from this step into hypocotyl and seed coat, Shafts and seed coats are advantageously reused. SOLUTION: A separator for dehulling and decotyling swollen soybeans and separating a seed coat and a hypocotyl from cotyledons, and a hypocotyl and a seed coat discharged from the separator are separated into at least two types of eyes having different openings. The vibrating sieve comprises a vibrating sieve that separates and extracts the hypocotyl and seed coat by passing through a vibrating sieve, the vibrating sieve having at least two-stage sieves whose upper sieve is larger than the lower sieve. Has a supply port for a mixture of hypocotyl, seed coat and water, A seed coat outlet is provided above the upper sieve, a hypocotyl outlet is provided above the lower sieve, and a water outlet is provided below a water receiving chamber provided below the lowermost sieve, A member that changes the rotation of the motor into vibration to vibrate all sieves is provided. |
