The 5XFZ-20C1S double‑stage seed cleaner, equipped with an SM screening module, integrates wheat dehulling, dual air separation, dual density sorting, and dual vibration screening into a single unit. It also features a bucket elevator and a screw dust collector. This high‑performance wheat seed‑cleaning machine effectively removes light impurities—such as chaff, husks, bran, and dust—as well as low‑bulk‑density defective grains—including jointed wheat, insect‑damaged kernels, and moldy seeds—along with large and small foreign matter like straw, sand, gravel, and fine soil. Having been on the market for three years, it has earned widespread acclaim from seed‑processing enterprises and grain‑procurement professionals alike.
