Abstract
A steam injection device for a vertical steam conditioning chamber for particulate material has one or more hollow modules having substantially conical tops and open bottoms arrayed along a support column extending from below the conditioning chamber to a point above the chamber. Steam for conditioning is supplied preferably through the support column in such a way that it uniformly permeates the particles along the height of the conditioning chamber as well as across its cross section. Additionally, by employing modules having other than symmetrically conical tops, it is possible to impart an irregular flow path to the particles being conditioned in the chamber. This permits uniform exposure of the particles to the steam in the conditioning chamber and, thus, promotes uniform conditioning.
