Ultrasonic fruit and vegetable cleaning machine mainly uses high-frequency vibration of ultrasonic waves to generate a large number of tiny bubbles, which are amplified and closed to form negative pressure to remove dirt and impurities on the surface of fruit peels. However, the defects of ultrasonic fruit and vegetable cleaning machine are quite obvious, and its effect on strong adhesion of pesticide residues is poor. A considerable number of ultrasonic fruit and vegetable cleaning machines, in order to achieve better cleaning results, will be equipped with (many companies claim to be herbal degreasing) cleaning powder, which is actually a chemical cleaning agent for cleaning and relies on chemical action to remove pesticide residues, but in fact, it produces secondary pollution.

The ozone fruit and vegetable cleaning machine mainly utilizes the bactericidal and pesticide residue removing effects of ozone to achieve the purpose of fruit cleaning and pesticide residue removal. The effectiveness of ozone fruit and vegetable machine is relatively high.

Ultrasonic+ozone fruit and vegetable cleaning machine has the advantages of relatively good functionality, strong automation, and hands-free operation. However, its disadvantages are high price and large footprint (requiring a large kitchen), as it does not require manual labor and works for more than 15-20 minutes. A considerable number of fruit and vegetable cleaning machines add detergent to achieve a clean effect, and food also faces the problem of secondary pollution.

So, it's not that the more expensive the fruit and vegetable cleaning machine, the better its actual effectiveness. The key is to consider everyone's needs comprehensively: kitchen area, functional requirements, and high efficiency in removing pesticide residues. Horizontally speaking, the ozone fruit and vegetable cleaning machine is more practical.
