FIELD: food processing industry, analysis.

SUBSTANCE: invention relates to a method for assay of dry matters, sugar and non-sugar in the parent molasses. Method involves heating molasses to non-saturated state in a temperature-controlled capacity, dissolving vibrating sugar crystals placed into a netted vibrating cylinder in molasses under condition of vibrating motion of cylinder. Then the maximal content of dry matters is measured by the value of electric resistance and purity index of saturated molasses is determined with taking into account the measured maximal content of dry matters< and the saturation coefficient is calculated. Then dynamic viscosity of saturated molasses at the thermostatic control temperature is measured and the ratio non-sugar : water is determined and the dynamic viscosity model coefficients are calculated. Then the content of dry matters in saturated molasses is measured by the dynamic viscosity formula depending on centrifugation temperature and assigned values of maximal dynamic viscosity and minimal purity of saturated molasses. Then the value of purity of saturated molasses at centrifugation temperature with taking into account of sucrose solubility in pure solutions from temperature and the saturation coefficient is measured. Then the square deviation value is determined that is measured by the formula of dynamic viscosity at the centrifugation temperature from the assigned maximal viscosity. As a assigned value of purity of saturated molasses method involves using its minimally possible value attained in a crystallizer-cooling device, and each the following saturation of molasses is carried out at the thermostatic-control temperature distinguishing from the temperature of previous saturation by 5-10°C (for example, by cyclic schedule 55°C, 50°C, 45°C, 40°C, 55°C and so on). The obtained value is compared with the assigned small value by varying values of dry matters and purity of the saturated molasses. The optimal value of parameters of normal molasses is fitted by the comparison result. Invention provides enhancing the precision of assay of the content of dry matters and purity of normal molasses as compared with the known by 0.3-0.5%.

EFFECT: improved method of determination of parameters.
