Fertilizers containing animal nutrient core packet

a technology of animal nutrient core and fertilizer, which is applied in the field of fertilizer compositions, can solve the problems of increased infant mortality, reduced mean birth weight, and reduced nutrient content of fertilizer core, so as to reduce the deficiency of human/domesticated animal diet, increase the amount of crops containing nutrients, and eliminate the effect of deficiency

Benefits of technology

[0013]The present invention further includes a method of delivering human/domesticated animal nutrients that have been determined to be deficient, in a deter...

Problems solved by technology

Iodine deficiency has been associated with mental retardation and brain damage, lower mean birth weight and increased infant mortality, hearing impairment, impaired motor skills, and neurological dysfunction.
Young children and pregnant and postpartum women are the most commonly and severely affected because of the high iron demands of infant growth and pregnancy.
Iron deficiency may, however, occur throughout the life span where diets are based mostly on staple foods with little meat intake or people are exposed to infections that cause blood loss (primarily hookworm disease and urinary schistosomiasis).
Zinc deficiency is la...

example 1

Product NP-3, NP-4, and NP-5

[0042]Samples were produced containing 1, 3, and 5% iron from iron sulfate core packet. Iron sulfate crystals were screened to a pre-determined size prior to being over-coated with urea. Sample NP-3 contained 5% iron was produced by screening the iron sulfate crystals to 1.7 to 2.0 mm. Sample NP-4 contained 3% iron was produced by screening the iron sulfate crystals to 1.4 to 1.7 mm. Sample NP-5 contained 1% iron was produced by screening the iron sulfate crystals to 1.0 to 1.2 mm.

[0043]Approximately 1 pound of each core material was placed inside the drum to form a falling curtain. The urea over-coating drum was 20″ in diameter, 5″ wide, 2″ deep, with forty-1″ lifting flights mounted 1½″ apart inside the drum to assist in forming a falling curtain during melt spray granulation. The stainless steel granulation drum was mounted on a variable speed base. The drum speed during granulation was 35-40 rpm. Industrial grade urea was melted and sprayed to overcoa...

example 2

NP-6

[0044]A sample was produced containing 1% iron from an iron EDTA (ethylene diamine tetra acetic acid) core packet. Iron EDTA nutrient cores were produced by first granulating powdered iron EDTA with 6-7% corn syrup in a lab scale pan granulator. Sample NP-6 contained 1% iron that was produced by screening the granulated core to a particle size of 1.0 to 1.4 mm.

[0045]Approximately 1 pound of nutrient core material was placed inside the drum to form a falling curtain. The urea over-coating drum was 20″ in diameter, 5″ wide, 2″ deep, with forty-1″ lifting flights mounted 1½″ apart inside the drum to assist in forming a falling curtain during melt spray granulation. The stainless steel granulation drum was mounted on a variable speed base. The drum speed during granulation was 35-40 rpm. Industrial grade urea was melted and sprayed to overcoat the core packet and produce a final product size of 2.8 mm.

NP-7

[0046]A sample was produced containing 1% zinc from a zinc EDTA core packet. Zinc EDTA nutrient cores were produced by first granulating powdered zinc EDTA with 6-7% corn syrup in a lab scale pan granulator. Sample NP-7 contained 1% zinc that was produced by screening the granulated core to a particle size of 1.0 to 1.4 mm.

[0047]Approximately 1 pound of core material was placed inside the drum to form a falling curtain. The urea over-coating drum was 20″ in diameter, 5″ wide, 2″ deep, with forty-1″ lifting flights mounted 1½″ apart inside the drum to assist in forming a falling curtain during melt spray granulation. The stainless steel granulation drum was mounted on a variable speed base. The drum speed during granulation was 35-40 rpm. Industrial grade urea was melted and sprayed to overcoat the core packet and produce a final product size of 2.8 mm.

Abstract

A fertilizer supplying animal nutrients including a core particle having an outer surface and comprising compounds containing animal nutrients, and a coating of urea on the outer surface of the core particle, and further a process of making the fertilizer including the steps of: screening animal nutrient core particles comprising a powdered substance containing an animal nutrient, to a preselected particle size; spraying melted urea onto the surface of the nutrient core particles to produce a coating on the nutrient core particles; granulating the nutrient core particles with sprayed melted urea to produce nutrient core granules; and cooling the nutrient core granules.
