PROBLEM TO BE SOLVED: To provide a simple machine capable of efficiently removing a seed coat and a hypocotyl swelled with water and producing a bean curd good in taste and color, having a small thermostable cell number and excellent in keeping quality especially for soybeans. SOLUTION: This machine for removing a seed coat and a hypocotyl of a seed is obtained by alternately arranging high-speed rotating rods 9 and low- speed rotating rods 8 rotating in the same direction in close vicinity at a gap 10 for enabling at least the seed coat and hypocotyl to pass therethrough kept between the rotating rods 9 and 8, keeping the peripheral speed of the high-speed rotating rods 9 at 3-15 times that of the low-speed rotating rods 8 and providing at least one row of protruding parts 11 protruding in the centrifugal direction on the outer periphery in the shaft direction in the high-speed rotating rods 9, further making the height of the high-speed rotating rods 9 and low-speed rotating rods 8 remarkably different in the conveying surface for the seed and preferably reducing the height of the high-speed rotating rods 9 from that of the low-speed rotating rods 8. |
