Fruit and vegetable cleaning machines are mainly divided into the following types:
Using ultrasonic waves to propagate in liquids to generate positive and negative alternating sound pressures, forming jets to impact fruits and vegetables, it can clean dust and sand on the surface of fruits and vegetables, and can also remove some agricultural residues, but the cleaning effect is unstable, and the surface of fruits and vegetables may be damaged under high-frequency vibration.
Using an ozone generator to generate ozone, ozone has a good sterilization effect, can sterilize, remove odors and reduce agricultural residues. However, ozone emitted in the air will irritate the human respiratory tract and cause physical discomfort.
Hydroxyl free radicals (-OH) are generated by electrolyzing water. This active free radical can react with pollutants such as pesticides, hormones, pigments, antibiotics, and bacteria to generate carbon dioxide, water and inorganic salts, which play a role in sterilization, disinfection, and removal of agricultural residues. Hydroxyl free radical technology cleans thoroughly, has few side effects, no secondary pollution, and is environmentally friendly.
