granulerade

Granulerade is a term used primarily in Swedish to describe materials that have been processed into granules. A granule is a discrete particle larger than a powder but smaller than typical pellets, with sizes that vary by industry. Granulerade materials are characterized by a defined particle size distribution, improved flow properties, and easier handling compared with bulk powders.

Granulation refers to the processes used to produce granulerade materials. These include wet granulation, where a binder is added to promote cohesion, followed by drying and milling to a target size; and dry granulation, such as roller compaction, where powders are compacted and milled into granules without a liquid binder. Other methods used in specialized sectors include spray drying and extrusion-spheronization, particularly in pharmaceutical manufacture.

Key properties of granulerade products include particle size distribution, moisture content, apparent density, flowability, compressibility, and porosity. These attributes influence processing performance, such as mixing, dosing, tablet formation in pharmaceuticals, or controlled release in fertilizers. Granulation can also affect solubility and dissolution rates, depending on formulation and intended use.

Applications span several sectors. In pharmaceuticals, granulerade powders improve content uniformity, flow, and tablet production. In the food industry, granulated sugars, salts, and coffee products are common examples. In agriculture, granulerade fertilizers enable controlled release and easier handling. In construction and chemical processing, granulerade materials can include additives and catalysts supported on granular carriers.

Quality control for granulerade materials typically involves granulometry analysis, moisture management, and assessment of dust generation and segregation tendencies. Safety considerations address dust control and binder residues, along with regulatory requirements for specific applications.
