The sink dishwasher I bought at home has this function. Let me introduce it to you. It will send out high-frequency oscillation signals through the ultrasonic sounder to peel off pesticide residues on the surface of fruits and vegetables. That is, during the cleaning process, when the ultrasonic intensity reaches a certain value, billions of bubbles will be formed in the water. When these bubbles explode around the fruits and vegetables, , the impact force generated will destroy the stains and pesticide residues on the surface of fruits and vegetables. If you still find it difficult to understand, let me give you an example. Everyone has seen a balloon burst, right? The moment the balloon explodes, the air around the balloon will be driven up. If it falls to the ground, the surrounding paper scraps, dust, etc. will be shaken up. The same is true for dishwashers to remove pesticide residues. Dirt and pesticide residues on the surface of fruits and vegetables It was "shocked up" in this way, and then washed away by the powerful water flow brought by the "turbulent rapid washing" technology. This principle is called "high-frequency ultrasonic turbulence" and is the patent of FOTILE's original invention of sink dishwashers. I chose FOTILE sink dishwashers because of this.
