Abstract
Abstract 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
155 words
An apparatus for continuously extruding, enzyme inactivating, pelletizing and drying/cooling of cereal bran comprising: a feed screw and surrounding barrel extending horizontally from the bottom of a hopper; a main screw and surrounding barrel arranged at a right angle to and space below said feed screw and a connecting passage between said barrels a frustoconical top which is secured to the end of said main screw, said top being provided with a flight; a housing surrounding said top secured at one end to said main screw surrounding barrel and having an extrusion die with a plurality of openings at the other end; an agitating means positioned in said hopper, said means having an intermittently operable ratchet gear drive system connected with said feed screw; a vibrational drying and cooling device mounted after said extrusion die at a negative angle of inclination; and a blower system which is operatively connected to said drying and cooling device.
Claim 2
Independent Claim
155 words
An apparatus for continuously extruding, enzyme inactivating, pelletizing and drying/cooling of cereal bran comprising: a feed screw and surrounding barrel extending horizontally from the bottom of a hopper; a main screw and surrounding barrel arranged at a right angle to and space below said feed screw and a connecting passage between said barrels a frustoconical top which is secured to the end of said main screw, said top being provided with a flight; a housing surrounding said top secured at one end to said main screw surrounding barrel and having an extrusion die with a plurality of openings at the other end; an agitating means positioned in said hopper, said means having an intermittently operable ratchet gear drive system connected with said feed screw; a vibrational drying and cooling device mounted after said extrusion die at a negative angle of inclination; and a blower system which is operatively connected to said drying and cooling device.
Claim 3
Dependent Claim
27 words
