An apparatus for continuously extruding and drying/cooling cereal bran is provided. This apparatus comprises a feed screw extending horizontally from the bottom of a hopper, a main screw arranged in the cross direction to said feed screw at a proper position spaced under said feed screw, a frustoconical main screw top which is secured to the end of said main screw, said top being provided with a flight therearound, an agitating means positioned in said hopper, said means being operated intermittently by way of a ratchet gear system being operated by the revolution of said feed screw, a drying/cooling device vibrating at a certain angle of inclination, and a blower system which is connected directly to said drying/cooling device. With use of this apparatus, it is possible to produce even sized enzyme inactivated pellets of bran having a desired size and strength.
