Abstract

Abstract The invention provides a highly nutritional unfermented medium protein animal feed supplement by admixing wet corn bran having an abnormally high moisture content with concentrated corn steep to form a moist cohesive but friable mass, the process elminating a significant proportion of the energy used in and pollution occasioned by prior art process. In a modification, the above unfermented product is subjected to a natural fermentation stage resulting in a fermented supplement which is microbiologically and gravitationally stable for an extended period of time. One further advantage of the present invention is that the corn bran and steep liquor from a corn wet milling plant can be used in the specific amounts as actually produced in the normal operation of the plant, thereby allowing plant efficiencies to be maintained.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 161 words
A process for producing a moist, cohesive, friable, readily transportable animal feed supplement from wet corn bran and corn steep liquor exiting a wet corn milling process consisting essentially of: (a) mechanically de-watering the wet corn bran to a solids content of from 30% to 50% by weight; (b) thoroughly admixing the de-watered bran with concentrated corn steep liquor having a solids content of from 40% to 55% by weight in a ratio of de-watered corn bran:concentrated corn steep liquor of from 3:1 to 1:2, the resulting mixture having a solids content of from 35% to 50% by weight; and (c) compacting the resulting mixture to form a moist, cohesive, friable, readily transportable mass having a bulk density of from 50 to 65 lb/cuft, a pH of less than 4.5 and a protein content of at least 20% on a dry matter basis said animal feed supplement having storage stability for a period of time from two weeks to seven months.
Claim 2
Dependent Claim 161 words
A process for producing a moist, cohesive, friable, readily transportable animal feed supplement from wet corn bran and corn steep liquor exiting a wet corn milling process consisting essentially of: (a) mechanically de-watering the wet corn bran to a solids content of from 30% to 50% by weight; (b) thoroughly admixing the de-watered bran with concentrated corn steep liquor having a solids content of from 40% to 55% by weight in a ratio of de-watered corn bran:concentrated corn steep liquor of from 3:1 to 1:2, the resulting mixture having a solids content of from 35% to 50% by weight; and (c) compacting the resulting mixture to form a moist, cohesive, friable, readily transportable mass having a bulk density of from 50 to 65 lb/cuft, a pH of less than 4.5 and a protein content of at least 20% on a dry matter basis said animal feed supplement having storage stability for a period of time from two weeks to seven months.
Claim 3
Dependent Claim 22 words
A process according to claim 1 wherein the pH of the moist cohesive mass of step (c) is from 3.50 to 4.2.
