It cleans the stone, soil, all dust particles and bacteria of wheat with water. It has a double seal device that prevents oil and water from mixing. - The entry point of the wheat to the washing tub is taken back and forth to adjust the time that the wheat stays in the water. The upper screw rotates rapidly and performs the washing process by shaking the water. - Foreign materials (stones, etc.) heavier than wheat sink to the bottom and are thrown out with the counter-rotating gizzard screw. - Light substances such as dust, straw and garbage in the wheat are collected on the surface of the water and thrown out with water through the husk hole. - Wheat dragged by the top screw goes to the vertical drying section working with the centrifuge system. The pallets, which are in the vertical drying and rotating rapidly, throw the product towards the perforated sheet metal, allowing the water to be purified from the wheat. - Wheat that is purified from water (moist) is transferred to the warehouses from the exit section in the upper head.
