The seed cleaner is an agricultural processing machine designed to separate and remove impurities, damaged seeds, dust, chaff, stones, and other foreign materials from harvested seeds. It typically consists of a feeding hopper, vibrating screens of different mesh sizes, an air aspiration system, collection outlets, and a power-driven mechanism. The machine is engineered to improve seed quality, purity, and germination potential, making it suitable for seed processing plants, farms, and grain handling facilities.

In operation, seeds are fed into the hopper and distributed onto the vibrating screens, where they are sorted according to size. Simultaneously, an air aspiration system removes lighter impurities such as dust, husks, and chaff. Larger and smaller unwanted materials are separated through the screening process, while clean seeds are discharged through designated outlets for collection. The operator adjusts airflow and screen settings to suit different seed types, ensuring efficient cleaning and consistent output quality.
