Title: OPTIMIZED SYSTEM AND METHOD FOR MAKING EXTRUDED GRANULAR ABSORBENT AND CLUMPING GRANULAR ABSORBENT PRODUCT
Abstract:
A method of making an extruded granular absorbent is provided where the method includes providing an extruder and a starch-containing admixture, and pressurizing the starch containing admixture in the extruder under relatively high extrusion pressures to extrude the pressurized starch-containing admixture from the extruder, and producing a water absorbent and oil absorbent extrudate. The present invention further provides that the extruded granular absorbent may be combined with a non-extruded granular material with relatively high inert or cellulose content where there may be a greater proportion of extruded granular absorbent, and the extruded granular absorbent and non-extruded granular material agglutinate into a clump when wetted with water or urine.
