At the Changji Tenghongyuan commerce color selection experience site, the TK nuts color sorter  easily selected various impurities, especially when the two or three huge stones were selected out of the impurities, it made a banging sound, which was shocking. Many customers present. Prior to the Qingdao Peanut Trade Fair, the TK peanut color sorting machine has been well-known for removing impurities such as thick and long branches and roots.

At the on-site meetings in Changji and Juxian, the TK nuts color sorting machine specifically compared and tested the data of the color sorting machine's loss reduction and production increase compared with the ordinary color sorting machine-in different application scenarios, the data ranged from 2% to 6%. The optical sorting machine selects peanut to protect white petals, selects peeled and broken petals to protect patterned rice, and selects sunflower seeds to select flowers to protect white and other blemish and corrective technologies that double the value of non-invasive and high-yield.
