Abstract

DC60 (09/04/41) This invention relates to a free-flowing and easily operated procedure for the preparation of a methionine-based animal feed supplement that produces a granulated product starting from a methionine salt solution in the usual manner, and yields a granulated methionine product in this way.

Claims (19)

1. A process for preparing free-flowing, methionine-based animal feed supplements characterized by the transformation of a methionine salt solution into granulated material. 2. The process described in claim 1 is specific in that it dries an atomized solution of methionine salts and granules the resulting powder. 3. The process described in claim 1 is characterized by the simultaneous drying and granulation of an atomized methionine salt solution in a fluidized layer. 4. One or more of the processes under claims 1 through 3 are characterized by the transformation of a solution of methionine salts into a granulated material by means of a forming process (extrusion may be selected) (sic). 5. One or more of the processes under claims 1 through 4 are characterized by the specific treatment of methionine salt solutions with activated carbon prior to atomization, drying, and/or granulation. 6. Any one or more of the processes under claims 1 through 5 are characterized by the aerosolization and/or granulation of a methionine salt solution incorporating silida-based additives. 7. The process under claim 6 has specific characteristics: 1. Hydrophilic or hydrophobic silita, prepared by precipitation or of a pyrogenic nature, is used as an additive in an amount equal to 0.1 to 10% by weight of the solid. 8. The process described in claim 6 is specific in that it uses finely powdered zeolite or bentonite as an additive in an amount of 0.1 to 10% by weight of the solid. 9. The process under claim 6 is characterized by the use of acid, patty and/or its altali metal salt/its altali metal salt as additives in amounts of 0.1 to 10% by weight relative to the solid. 10. One or more of the preceding claims are characterized by the use of a 10 to 10% solution of methionine-based composition. 11. The process under claim 10 is specific in that it uses a solution with a strength of 25 to 50%. 12. One of the preceding claims' procedures has specific characteristics involving the use of solutions of Na and/or K methionine. 13. The procedure under claim 12 is specific in that it uses a sodium dethioninate solution. 14. One or more of the preceding claims provide a specific process that yields a powder with a bulk density of 350 to 500 kg/m³ and a dust content of 1 to 5% after atomization, drying, and granulation. 15. One or more of the preceding claims are characterized by the production of a powder obtained by atomization and drying into granules in combination with a saturated solution of methionine salts in a mixer with strong shear action. 16. The process under claim 15 is specific in that the weight ratio of the powder to a saturated solution of methionineate adsorbed from the solid substance is in the range of 1:0.01 to 1:0.5. 17. The process under one or more of the preceding claims is of a specific nature that performs granulation in a fluidized layer which may be fitted with an interleaved crushing device. 18. One or more of the preceding claims (sic) are characterized by the use of extrusion shaping techniques to obtain granulated material which may be used in conjunction with an intensive mixer or a fluid drying layer. 19. A highly free-flowing granulated methionine material is characterized by a) a density of >650 kg/m³, b) a particle size distribution of 63 to 5000 µm, and c) a particulate matter content of less than 1%.
