Principle of fruit and vegetable cleaning machine

The principle of fruit and vegetable cleaning machine is mainly based on a variety of technologies, including electrolysis of water, ozone, ultrasound and hydroxyl water ion purification. The following is a detailed analysis of these technologies: ‌

‌Electrolysis water technology‌
Electrolysis water technology decomposes water into hydrogen and oxygen through electrochemical reactions. These gases can penetrate the surface of fruits and vegetables and take away harmful substances such as dirt, bacteria and pesticides attached to the surface. Hydrogen ions and oxygen ions can also destroy pesticide molecules and bacterial cell walls, making them inactive, thereby achieving the effect of cleaning and sterilization.

‌Ozone technology‌
Ozone has strong oxidizing properties and can quickly oxidize pesticide and hormone molecules to degrade them. At the same time, ozone can also effectively kill bacteria. However, excessive ozone concentration may destroy vitamin C in fruits and vegetables, and under certain conditions may produce more toxic degradation products, posing a risk of secondary pollution.

‌Ultrasonic technology‌
Ultrasonic cleaning machines use high-frequency vibrations to generate cavitation bubbles. The energy released when the bubbles burst can disintegrate pesticide residues and dirt. This technology has the effect of physical cleaning and sterilization, but may cause damage to the skin of fruits and vegetables.

‌Hydroxy water ion purification technology‌
Hydroxy water ion purification technology produces hydroxyl ions through titanium alloy electrolytic sheets. These ions can efficiently degrade pesticide residues and sterilize. This technology is relatively safe and has been recognized by industry standards, and will not cause harm to the human body.

‌Synergistic technology‌
Some high-end fruit and vegetable washing machines combine multiple technologies, such as the synergistic effect of ultrasound and active oxygen sterilization, to further improve the cleaning effect. The intelligent recognition system can also automatically adjust the cleaning intensity according to the type of fruit and vegetable to optimize the cleaning efficiency.

‌Summary‌
The principles of fruit and vegetable washing machines are diverse, and different technologies have their own advantages and disadvantages. Electrolyzed water and hydroxyl water ion purification technologies are relatively safe and efficient, while ozone and ultrasonic technologies require attention to the conditions of use. When choosing, you can weigh them according to actual needs and the type of fruit and vegetable.
