preparation example

[0157] The following examples illustrate the basic method and versatility of the compositions of the present invention. Amino acids and their polymers, derivatives or salts are exemplified in Preparation Examples, and any other amino acids and their polymers, salts, complexes or derivatives thereof may be substituted. It should be noted that the present invention is not limited to these examples.

[0158] A. Water-dispersible granular composition of sulfur element and amino acid and polymer, salt, derivative or mixture thereof

Embodiment 1

[0159] Example 1: 25% of glycine and 55% of the water-dispersible granule composition of sulfur element: by mixing 55 parts of sulfur element, 25 parts of glycine, 5 parts of naphthalenesulfonate condensate, 9 parts of malt paste Essence, 3 parts kaolin, 3 parts silica, mixed to obtain a blend. The resulting blend is mixed with water and ground in suitable mixing equipment to form a slurry or wet mixture.

[0160] The obtained wet milled slurry was spray dried at an inlet temperature of less than 175°C and an outlet temperature of less than 90°C to obtain granulated powder. The composition has the following particle size distribution: D10 less than 2 microns; D50 less than 4 microns, D90 less than 9.5 microns. The particle size of the composition is in the range of 0.1-1.5 mm. The composition has dispersibility of 85%, suspendability of 90%, wet sieve retention of 0.8%, wettability of less than 30 seconds. Under accelerated storage conditions, the composition further exhibi...

Embodiment 2

[0161] Example 2: 60% lysine and 20% sulfur element water dispersible granule composition: similar to Example 1, using 60 parts of lysine, 20 parts of sulfur element, 4 parts of naphthalenesulfonic acid , 8 parts of starch, 3 parts of silicon dioxide and 5 parts of bentonite to prepare the composition. The composition has the following particle size distribution: D10 less than 9 microns; D50 less than 11 microns and D90 less than 20 microns. The particle size of the composition is in the range of 0.1-2.5 mm. The composition has 90% dispersibility, 95% suspendability, 1.5% wet sieve retention and wettability of less than 100 seconds. The composition also exhibits about 80% suspendability, 85% dispersibility under accelerated storage conditions.
