Used to determine the pink color, bran star area ratio, bran star density, maximum bran star area, black dot area ratio, whiteness, and processing accuracy level of wheat flour, in compliance with the national standards "GB/T 27628-2011 Grain and Oil Inspection - Determination of Pink and Bran Stars in Wheat Flour" and "GB/T 5504-2011 Grain and Oil Inspection - Inspection of Processing Accuracy of Wheat Flour".

2、 Main performance indicators:

1. ★ Automatically measure the pink color (represented by L, a, b), proportion of bran star area (the ratio of bran star area on the sample surface to the sample surface area in%), bran star density (the number of bran stars per cm2), maximum bran star area (mm2), proportion of black spot area (the ratio of black spot area on the sample surface to the sample surface in%), and whiteness (blue light whiteness) of wheat flour;

2. Based on the standard sample of wheat flour processing accuracy, automatically determine the processing accuracy level of the sample (special grade one, special grade two, standard flour, ordinary flour);

3. ★ Meet the requirements of the national standards GB/T 27628-2011 Grain and Oil Inspection - Determination of Pink and Gluten Stars in Wheat Flour and GB/T 5504-2011 Grain and Oil Inspection - Precision Inspection of Wheat Flour Processing;

4. Measurement accuracy: chromaticity value (pink) 0.01, bran content 0.01%, whiteness 0.01;

5. ★ Repeatability accuracy: The same sample is measured twice, with chromaticity value (pink) △ E * ab ≤ 0.2, bran content ≤ 0.2%, and whiteness ≤ 0.3;

6. Measurement time: fastest 30 seconds;

7. Preheating time: 20-30 minutes;

8. ★ Camera resolution: ≥ 5 million pixels;

9. Can automatically determine whether the sieve is leaking (compare the maximum size of a single bran star with the set value);

10. The instrument can be automatically calibrated according to the standard whiteboard verified by national metrology institutions;

11. It can display the detection screen and results in real time, and save the detection results and marked images on the computer;

12. You can freely query data and analyze labeled images based on time, product name, inspector, etc., and generate Excel spreadsheets.

3、 Instrument specification configuration:

One host, one set of flour forming machine, one standard whiteboard block, one Wanshen SC-X0 pink bran star detection software CD (including electronic operation manual and camera driver), and one software lock. (Computer needs to be equipped separately)

The total dimensions and weight of the instrument are approximately 45cm in width, 40cm in depth, and 40cm in height, weighing around 7kg.

Temperature of 10-30 ℃, relative humidity ≤ 85%. The instrument should be placed on a stable workbench with no strong mechanical vibration or electromagnetic interference around it; The power requirement is 220V ± 10%, 50Hz
