Wheat washing can remove stone, dampen and clean. It works by the water solubility and flushing action to purify surface of wheat. For water consumption and pollution of traditional wheat washing machines have become increasingly prominent, the water-saving cleaning technology based on grading washing was studied. In this paper, principle on grading washing is first shown. In order to make full use of grading washing effect, a realization solution based on grading washing technology is designed. For verifying the effect on grading washing, comparative experiments were done. After wheat is sent into washing machines, primary-washing, secondary-washing and final-washing are completed. Compared with traditional wheat wet washing technology, the measurement value about cleaning effect is not reduced. With the water-cycling system, effective reuse for water is achieved. water-saving is about 2/3. The pollution to environment is reduced fundamentally, and the production cost of enterprises is significantly reduced.
