Abstract
A preferred preconditioning device for use with an extruder includes two juxtaposed, frustocylindrical, intercommunicated chambers one of which presents a greater cross-sectional area than the other. A respective pair of rotatably driven mixing shafts extend axially through corresponding chambers with each mixing shaft having a plurality of mixing elements coupled therewith. The mixing elements are arranged, in order to present in cooperation with the chambers, a plurality of conditioning zones preferably including a mixing zone for initially mixing the material, an intermediate retention zone providing increased retention time for enhancing equilibration between solid and liquid portions of the material, and a final tertiary zone for comminuting clumps of material.
