Wheat Flour Processing Accuracy Tester

Instrument Introduction The Wheat Flour Processing Accuracy Tester measures **flour color, bran speck content, number of bran specks per unit area, maximum bran speck area, and whiteness** of wheat flour. For the same sample, the difference in bran specks between two tests is less than 10% of the arithmetic mean. Chromaticity repeatability: △E*ab ≤ 0.5. Compliance Standards - Verified for standard applicability by the Grain Bureau Standard Quality Center. - Meets the testing requirements for wheat flour processing accuracy industry standard samples issued by the Grain Bureau. - Complies with **GB/T 27628-2011 Inspection of Grain and Oils - Determination of Flour Color and Bran Specks in Wheat Flour**. Basic Parameters 1. Light source: simulated D65 illuminator 2. Flour color expression: CIE L*a*b* color space values (L, a, b) 3. Bran speck content: ratio of bran speck area to sample surface area (%) 4. Whiteness expression: blue light whiteness Wb 5. Display: large LCD touch screen 6. Indicating accuracy: whiteness ≤ 0.1 7. Repeatability precision: for the same sample, the difference in bran specks between two tests is less than 10% of the arithmetic mean 8. Chromaticity repeatability: △E*ab ≤ 0.5 9. Warm-up time: 30 minutes 10. Power supply: AC 220 V ±10%, 50 Hz 11. Operating temperature: 0 ℃–40 ℃ 12. Relative humidity: ≤ 85% 13. Built-in embedded printer
