METHOD FOR ASSAY OF QUALITY OF SUGAR-CONTAINING MILK OF LIME Russian patent published in 2004 - IPC

FIELD: sugar industry.

SUBSTANCE: method involves weighting a milk of lime specimen with temperature 22-28 C and separation of lime solid particles from dispersion medium by centrifugation of a milk of lime specimen in filtering centrifuge. After centrifugation of milk of lime mass part of sugar in dispersion medium is determined by one of known methods. Then mass part of saccharate-bound lime in dispersion medium is determined by the following formula: G_CaO = (0.006 x CX² + 0.0395 x CX + 0.1074) - 0.119 wherein G_CaO is a mass part of saccharate-bound lime in milk of lime dispersion medium, % CaO to mass of dispersion medium; CX is a mass part of sucrose in milk of lime dispersion medium, %. The calculation of the content of active lime is carried out by the following formula: A_CaO = P_CaO - G_CaO wherein A_CaO is the content of active lime in milk of lime dispersion medium, % CaO to dispersion medium mass; P_CaO is the content of calcium hydroxide in milk of lime dispersion medium determined by one of the known methods, % CaO to dispersion medium mass. Invention provides precision of the quality assay of milk of lime by taking into account saccharate-bound calcium mass that is not an active lime.

EFFECT: improved assay method.
