ST-209 Wheat Bran Star Tester
ST-209 Wheat Bran Star Tester is made in accordance with the requirements of GB/T 27628-2011 Grain and Oil Inspection - Determination of Wheat Flour Pink and Bran Star. It uses a touch screen operation and can enlarge the display and measure the Bran Star content, black dot content, whiteness, and pink (L, a, b) values within 20 seconds. Based on the large Bran Star, it can determine whether the screen is leaking, save data and photos, facilitate querying, and completely change the situation of relying on the naked eye to adjust the process, Regular powder path testing can be conducted to determine whether the sieve is leaking and whether the process is reasonable through data comparison. This is the "wise eye" of powder technicians, allowing ordinary employees to have the same insight as powder technicians and ensuring the stability of the process.
Wheat flour processing accuracy tester - Flour processing accuracy tester - Bran star tester
Main performance characteristics:
