Provided is a bean sprout both end portions removing method for mechanically cutting and removing root portions and sprouting portions of bean sprouts. The method comprises a bean sprouts separating step to separate and remove undergrown bean sprouts, etc. from bean sprouts as harvested by a bean sprouts separating device ( 1 ), etc., a bean sprouts arraying step to array lengthwise directions of the bean sprouts by a bean sprouts arraying device comprising a grooved plate ( 31, 32 ) formed with longitudinal grooves ( 33 ) arranged in parallel and given with vibration including upward and downward components so that the bean sprouts supplied onto the grooved plate ( 31, 32 ) are moved into the longitudinal grooves ( 33 ) and have their lengthwise directions arrayed and a bean sprout both end portions cutting and removing step to cut and remove both end portions of the bean sprouts by a bean sprout both end portions cutting and removing device comprising a cutting conveyor ( 62 ) provided with a plurality of cutters ( 63 ) arrayed with their blade portions opposed to each other, said cutting conveyor repeating transfers and stops in a conveyor running direction, and a transfer conveyor ( 68 ) provided with transfer bars ( 67 ) and arranged above the cutting conveyor ( 62 ) to be continuously moved at a velocity lower than a velocity of the cutting conveyor ( 62 ). By a relative movement between the both conveyors ( 62, 68 ), the bean sprouts have their root portions and sprouting portions cut off by the cutters.
