  • Vegetable washing method capable of separating and splitting impurities, and machine for implementing same
    Patent number: 11089808
    Abstract: A method for cleaning fruit and vegetable ingredients is provided, in which the washing basket assembly agitates the water in the washing barrel to rotate upward to achieve the cleaning of fruit and vegetable. During the process of “cyclic cleaning in the barrel”, the drainage outlet in the center of the bottom of the washing barrel is closed to prevent the water from flowing out of the barrel cavity; when the drainage outlet in the center of the bottom of the washing barrel is opened and drained, the water body rotates to form eddy current drainage; fruits and vegetables in the washing basket alternately move centripetally and centrifugally. The number of exercises is proportional to the number of washes.
