ST-209 Wheat Flour Processing Accuracy Tester Grain Testing Equipment

Compliant with the national standard GB/T27628-2011 (Grain and Oil Inspection – Determination of Wheat Flour Pink and Bran Star), the ST-209 Wheat Bran Star Tester redefines efficiency and precision in flour quality testing. Featuring intuitive touchscreen operation, this advanced equipment delivers comprehensive test results in just 20 seconds – including bran star content, black dot content, whiteness, and pink (L, a, b) values – with enlarged display for effortless reading.
Beyond basic testing, it serves as a critical process monitoring tool: by analyzing large bran star particles, it quickly identifies sieve leakage issues. Equipped with built-in data and photo storage functions, it enables easy record retrieval and traceability, eliminating the traditional reliance on subjective naked-eye judgments for process adjustments.
Regular testing with the ST-209 allows mill operators to verify sieve integrity and optimize process rationality through data-driven comparisons. Dubbed the "smart eye" for flour technicians, this tester empowers ordinary staff to achieve the same professional judgment as seasoned technicians, ensuring consistent process stability and superior flour quality batch after batch.

Main performance characteristics:

● Fully automatic self check upon startup

● Automatically save multiple photos for comparative analysis; You can manually observe images for analysis.

● Determine the area ratio of colored impurities such as bran and black spots in flour; (Unit: parts per ten thousand)

● Measuring the pink color of flour can replace the whiteness meter;

● Measure the color L a and b values of flour;

● Predicting the ash content of flour;

● Determine if there is any leakage in the sieve;

● Can record other parameters of the sample, enriching sample query information; It can be recorded and queried based on production date, shift, and product name information;

Technical parameter
