A method and apparatus for severing roots of bean sprouts and dewatering the bean sprouts are disclosed. Bean sprouts are supplied onto a severing and dewatering table (11) having a number of severing slits (13) each of which has such a width that a root of a bean sprout falls into each severing slit. Air is caused to blow from above the severing and dewatering table (11) so that a flow of air flowing downward through the severing slits is produced to cause the roots of the bean sprouts on the severing and dewatering table (11) to fall into the severing slits (13). The roots of the bean sprouts fallen in the severing slits (13) are severed by a cutter blade (14) while water adherent to the bean sprouts are being blown away by wind pressure downward from the severing slits (13).
