Abstract

An anaerobic, pasteurizing conditioning system for treating matter such as whole and ground grain and minerals to increase the rate of conversion during digestion and thus the nutritional value thereof. The system comprises a direct fired steam generator adapted for producing treatment fluid comprising steam and non-condensible gases, the gases containing insufficient oxygen for substantial aerobic bacterial growth. The steam and oxygen deficient non-condensible gases are discharged into the vessel for counter-current flow relative to matter passing therethrough. The operation of the direct fired steam generator is controlled for producing a sufficiently large volume of oxygen deficient gases and steam for purging the matter of other gases flowing therewith and maintaining the deficient oxygen level in the non-condensible gases for creating an anaerobic condition. In this manner an improved feedstuff is provided wherein the starch components have first been gelatinized in a heated, anaerobic environment and thereafter fractionated to render the feedstuff more digestible.
