LAST CRYSTALLIZATION MASSECUITE PRODUCTION Russian patent published in 2001 - IPC

FIELD: sugar industry. SUBSTANCE: massecuite is boiled out in vacuum apparatus to 94-95% solids concentration and, before discharge from vacuum apparatus, diluted with hot water to 98.6-91.4% and subjected to crystallization on cooling at stirring in crystallyzers to required temperature, at which composition of intercrystal solution corresponds to composition of standard molasses. Once temperature 40-42 C is achieved, stirring with vibration frequency 2.0-4.0 s^-1 and amplitude 3·10^-3-6·10^-3 m is launched and continued until concentration of crystals in massecuite attains 46.0-48.0%. Resulting massecuite is then heated and centrifuged. EFFECT: reduced level of sugar in molasses, increased content of crystals in massecuite and thereby yield of sugar. 1 tbl, 3 ex
