Abstract
Abstract A molasses fermentation residue is converted into a coagulation product to use in preparing animal feed or fertilizer by concentrating a molasses fermentation residue to a solids level of at least 60 percent, heating the residue to about its boiling point and cooling, adding a soluble phosphate to the cooled residue and coagulating the residue-phosphate mixture by heating at about 105 DEG to 120 DEG C.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
105 words
A process for converting a molasses fermentation residue into a coagulation product comprising: a. concentrating said molasses fermentation residue to a solids level of from about 60 to about 80 weight percent thereof; b. heating the concentrated residue to about its boiling point to induce thickening thereof; c. cooling the concentrated residue to about 80° C.; d. admixing up to about 15 percent by weight, based upon the concentrated residue, of a soluble phosphate to form a resultant mixture; e. heating said resultant mixture to a temperature of from about 105° to 120° C until coagulation thereof is obtained; and, f. recovering the coagulation product.
Claim 2
Dependent Claim
105 words
A process for converting a molasses fermentation residue into a coagulation product comprising: a. concentrating said molasses fermentation residue to a solids level of from about 60 to about 80 weight percent thereof; b. heating the concentrated residue to about its boiling point to induce thickening thereof; c. cooling the concentrated residue to about 80° C.; d. admixing up to about 15 percent by weight, based upon the concentrated residue, of a soluble phosphate to form a resultant mixture; e. heating said resultant mixture to a temperature of from about 105° to 120° C until coagulation thereof is obtained; and, f. recovering the coagulation product.
Claim 3
Dependent Claim
19 words
The process of claim 1 wherein said soluble phosphate material is selected from phosphoric acid, ammonium phosphates and superphosphates.
Claim 4
Dependent Claim
16 words
The process of claim 2 wherein said superphosphates are selected from single, double and triple superphosphates.
Claim 5
Dependent Claim
12 words
The process of claim 2 wherein said ammonium phosphate is monoammonium phosphate.
Claim 6
Dependent Claim
18 words
The process of claim 1 further comprising drying the resulting coagulated product to form a friable non-hygroscopic solid.
Claim 7
Dependent Claim
12 words
The process of claim 5 further comprising granulating said friable non-hygroscopic solid.
Claim 8
Dependent Claim
16 words
The process of claim 5 further comprising grinding said friable non-hygroscopic solid to a powder form.
