C13 SUGAR INDUSTRY
Description
C13 covers the production, processing, and refining of sugars and sugar products from natural sources, primarily sugar cane and sugar beets. This includes extraction methods, crystallization, purification, and concentration processes, as well as the manufacture of molasses, syrups, and related by-products. The class encompasses equipment, apparatus, and chemical treatment techniques specific to sugar manufacturing operations. Related fermentation processes and uses of sugar in other chemical industries are classified elsewhere (e.g., C12 for fermentation biotechnology, C07 for organic chemical synthesis).
IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
2 shared codes have differing titles between IPC and CPC.
