Systems and methods for manufacturing solid granules

A method of manufacturing a solid granule for use as or in a cleaning agent, comprising:

• providing an anionic surfactant component having at least one anionic sulfonate surfactant and at least one anionic fatty alcohol-based sulfate surfactant;
• providing a granule-forming agent;
• mixing the anionic surfactant component and the granule-forming agent and molding into a solid mixture;
• receiving the solid mixture in a granulation device, wherein the granulation device comprises a first roller cutter, a second roller cutter, a plurality of first circular blades included in the first roller cutter, the plurality of first circular blades being placed in parallel with each other, a plurality of first circular grooves positioned between adjacent first circular blades of the plurality of first circular blades, a plurality of second circular blades included in the second roller cutter, the plurality of second circular blades being placed in parallel with each other, and a plurality of second circular grooves positioned between adjacent second circular blades of the plurality of second circular blades;
• the plurality of first circular blades being aligned with the plurality of second circular blades without contacting each other;
• cutting the solid mixture into a rough granule by cooperating the first circular blades with the second circular blades;
• and
• polishing the rough granule into a solid granule with a spherical shape having a sphericity of at least 0.95 by cooperating the first circular grooves with the second circular grooves.
