1. Ozone sterilization food purifier (also called active oxygen detoxification machine)
The principle of ozone sterilization food purifier: The molecular structure of ozone is unstable under normal temperature and pressure, and it will decompose into oxygen and single oxygen atoms by itself; and oxygen atoms have strong activity, have a strong oxidizing effect on bacteria, and destroy them , The excess oxygen atoms will recombine themselves into ordinary oxygen atoms, there is no toxic residue, so it is called pollution-free disinfection machine.
Therefore, when the food purifier is operating, the ozone generator generates ozone, which is transported by the ozone pump to the washing barrel of the vegetable washing machine through the ozone tube. In the washing barrel, it contacts the water machine and dissolves in the water to form ozone water to achieve sterilization and disinfection. , Degrade pesticides and remove residues on food surfaces.

2. Ultrasonic cleaning food purifier
The principle of ultrasonic cleaning and sterilizing food purifier: The sudden change in sound pressure when ultrasonic waves propagate in liquid causes strong cavitation and emulsification of the liquid, generating millions of tiny cavitation bubbles every second, which are rapid under the action of sound pressure A large amount of ground is produced, and blasting violently in succession, produces strong impact and negative pressure suction, which promotes the peeling of dirt and achieves the cleaning effect. Widely used in industry, it is suitable for the cleaning of some particularly small products with high requirements for cleanliness, such as clocks and precision machinery parts, electronic components, circuit board components, etc. At the same time, the noise pollution during ultrasonic cleaning is heavy.

Three, plasma sterilization food purification machine
The principle of plasma sterilization food purification machine: It uses water treatment technology to accelerate the activation of oxygen and hydrogen ions, transform them into plasma form to produce hydroxyl groups, and decompose, disinfect and purify organic and non-organic substances under non-thermal low temperature conditions. It leaves behind harmless by-products such as water and steam.

4. High-energy ion sterilization food purifier
The principle of the high-energy ion food purifier: It continuously provides electron beams to the ion reactor through the transducer, bombards the water molecules, makes them split rapidly, and produces hydroxyl radicals (-OH) with high electron deprivation ability, destroying the outer walls of bacteria and viruses , Make it lose its original activity; quickly take away the covalent electrons of the molecular chains of organic compounds such as pesticides and hormones, and convert them into substances that are harmless to the body such as carbon dioxide, water and inorganic salts, thereby removing pesticide residues and bacteria and viruses to restore the original food After removing the bacteria, it can be kept fresh for 7 days.

Depending on the type of food purifier, the working principle is different, but the function is the same. They are all to remove bacteria, residual pesticides, chemical hormones, etc. on the food, and to ensure the safety of consumers' tongues.
