Laboratory whiteness meter BLIK-R3
Laboratory whiteness meter BLIK-R3 BLIK-R3 is intended for express assessment of flour grade by whiteness and control of the technological process at flour milling enterprises, as well as for incoming flour quality control at bakery enterprises. Use for: determining the whiteness of wheat flour based on the values of the measured zonal reflection coefficients of the visible spectrum of rays of a certain wavelength from standards and a compressed flour sample; formation of the appropriate grade of wheat flour during its production at flour mills and incoming control of the baking properties of various grades of wheat flour supplied to bakeries; determining the ratio of different batches of wheat flour of the same variety to obtain a mixture with a given whiteness indicator, when carrying out flour of these varieties at a bakery; control of whiteness indicators of a wide range of recipe ingredients, semi-finished products and finished products (various types of starches, sugar- and starch-containing raw materials, stabilizers, skimmed milk powder, etc.; determining the ratio of different batches of wheat flour of the same type to obtain a mixture during the rolling process at a bakery with the values of the criterion reflecting the ability of the flour to darken during the preparation of dough that meets the requirements of the technological regulations for the production of wheat bread. The operating principle of the device is based on measuring the reflectance of the visible spectrum of rays in a given wavelength range from the compacted-smoothed surface of flour or dough and standards and determining the whiteness index. The device allows you to determine the whiteness of wheat flour of various grades in accordance with the requirements of GOST 26361. The microprocessor system of the Blik-R3 device provides the measurement process, processing of measurement results and monitoring the performance of the device, as well as outputting measurement results to a digital indicator and to a personal computer to form a database. The results are transferred to an IBM PC via the RS 232 C interface. The device is included in the State Register of Measuring Instruments under No. 16027 and is approved for use in the Russian Federation. Manba: https://www.nv-lab.ru/catalog_info.php?ID=357
