A food purifier is also a food detoxifier. Food detoxifier is a machine that detoxifies food and removes pesticide residues, bacteria, heavy metals, antibiotics, hormones, plasticizers and other harmful substances in food.
These ingredients include: meat, seafood, fish, leafy vegetables, stem vegetables, cereals, fruits, shells and so on.
The existing detoxification technologies or similar technologies in the market include: high-voltage pulsed static electricity, ozone, ultrasound, plasma, high-energy ions, photocatalyst and so on.
Extended data:
Classification:
1, high voltage pulse electrostatic detoxification
Advantages: Using high-voltage pulse electrostatic technology, tens of thousands of high-voltage pulses are generated every second, which changes the material balance in atoms, and the generated charges hit harmful particles of heavy metals in food materials, which has a strong adsorption effect. Heavy metal particles on the surface and inside of food are adsorbed on the negative wall of the instrument and mixed into water.
At the same time, under the action of strong electric field, harmful substances are ionized, generating free radicals, inactivating microorganisms, killing bacteria and removing pesticides. This technology is also the only technology on the market that can be used to remove heavy metals from ingredients.
Disadvantages: It involves the utilization of high-voltage electric energy, and it is difficult to make it into a portable form because of safety and insulation. In addition, because this technology is relatively high-end and has not been widely used for the time being, the cost of instruments manufactured by applying this principle is relatively high.
2. Ozone purifier
Advantages: the molecular structure of ozone is unstable at normal temperature and pressure, and it will decompose itself into oxygen and a single oxygen atom; Oxygen atoms are very active and have a strong oxidation effect on bacteria, so they can be eliminated.
Therefore, when the food purifier works, the ozone generator generates ozone, which is transported to the washing bucket of the vegetable washer through the pipeline by the ozone pump, and the ozone is dissolved in the water to form ozone water, thus achieving the functions of sterilization, disinfection, degradation of pesticides and removal of residual substances on the food surface.
Disadvantages: ozone is irritating to human respiratory mucosa, and the harm to human body is fatal when the concentration reaches a certain level; In addition, ozone has no effect on removing heavy metals from food.
3. Ultrasonic purifier
Advantages: When the ultrasonic wave propagates in the liquid, the sudden change of sound pressure causes intense cavitation and emulsifying phenomenon in the liquid, and millions of tiny cavitation bubbles are generated every second. These bubbles are produced rapidly and massively under the action of sound pressure, and then explode violently, producing strong impact force and negative pressure suction, promoting the peeling of dirt and achieving the cleaning effect.
Disadvantages: ultrasound itself does not have the function of sterilization. In general, the ultrasonic cleaning and sterilization food purifier is usually equipped with an active oxygen generator to complete the sterilization effect, and the effect is not significant. At the same time, the noise pollution is serious during ultrasonic cleaning. The cleaning ability of ultrasonic wave is very limited, and it is impossible to remove heavy metals from ingredients.
4. Ion purifier
Advantages: the water treatment technology is adopted to accelerate the activation of oxygen ions and hydrogen ions, which are converted into plasma to generate hydroxyl groups, and there is no thermal energy to decompose, disinfect and purify organic and non-organic substances at low temperature, leaving harmless by-products, such as water and water vapor.
Disadvantages: Although the disinfection ability of ion purifier is stronger than that of ozone sterilization, which avoids the negative impact of ozone sterilization, the cleaning ability of ions is weak, and it is impossible to remove the residual heavy metals in ingredients.
