论述了蔬菜清洗中气流对强化洗净率的作用机理 ,初步实验研究气流对洗涤水和蔬菜的扰动状况以及清洗效果。结果表明 ,在本试验条件下 ,大量空泡集聚在洗涤水上部并使清洗槽液面膨胀 0 .0 3m,射流的卷吸和空泡溃灭强化了对蔬菜的冲刷效果 ,并给出了马铃薯和小青菜在未浸泡和分别浸泡 10 min、30 min后的洗净时间 The mechanism of air flow on the rate of enhanced cleaning in vegetable cleaning was discussed. The disturbance of air flow to washing water and vegetables and the cleaning effect were studied experimentally. The results show that under the test conditions, a large number of cavities accumulate in the upper part of the wash water and cause the liquid level of the cleaning tank to expand by 0.30 m. The entrainment and cavitation collapse of the jet intensify the scouring effect on the vegetables, Potatoes and small vegetables in the soaking and soaking for 10 min, 30 min after the wash time
