Vegetable washing machine working principle and effect comparison!

There are many types of household vegetable washing machines, which can be divided into two categories according to the cleaning principle.

1, ultrasonic household vegetable washing machine

2, ozone household vegetable washing machine

(1) Analysis of ultrasonic household vegetable washing machine:

1, ultrasonic household vegetable washing machine cleaning principle

The ultrasonic cleaning machine is mainly composed of two main units, namely an ultrasonic generator (ultrasonic power supply) and an ultrasonic transducer (cleaning tank and acoustic head). The ultrasonic generator converts the 50HZ grid voltage into a high-frequency alternating current between 20KHZ and 3 5KHZ through rectification and inverter, and the ultrasonic transducer converts the high-frequency alternating current into electric energy from the form of electric energy. Sound waves are transmitted in a densely spaced phase, which makes it easy to pressurize and decompress liquids (or gases) in the propagation path, causing the liquid tissue to be cracked into numerous microvoids (so-called cavitation). The blasting of the void will cause a violent collision, causing the dirt attached to the solid surface to be peeled off. This process is called "cavitation effect". Since the cavitation effect is more easily generated between two different media, especially the liquid-solid interface, the effect of cleaning the denser solid using ultrasonic cleaning technology is obvious; and the ultrasonic wave is penetrating in the solid medium. The effect is that the inner and outer surfaces, regardless of the shape, can also obtain a good cleaning effect.

2, the use of ultrasonic household vegetable washing machine

1 Wash and remove pesticides, microorganisms, and bacterial viruses from vegetables such as grapes, cherries, apples, strawberries, cabbage, leeks, pork, and chicken.

2 disinfection of gold and silver jewelry, bracelets, pens, CDs, razors, combs, jewelry, headwear, brooches, glasses, toothbrushes, dentures, tea sets, etc.

3Using ultrasound for beauty skin care, long-term use can keep the skin fresh and lubricated and full of elasticity.

4 The use of ultrasonic cleaners can also be used for bartending and mellow alcohol.

3. Analysis of the effect of ultrasonic household vegetable washing machine

It is decided that the ultrasonic household vegetable washing machine has the effect mainly depends on the ultrasonic power. Because the ultrasonic application is very wide, the types and powers of ultrasonic waves used in different fields are different. Generally, the power for pesticides, hormones and microorganisms should be above 400W. In order to completely remove the pesticides, hormones and microorganisms from the water, vegetables and vegetables.

(2) Analysis of ozone household vegetable washing machine:

1, ozone household vegetable washing machine cleaning principle

The ozone household vegetable washing machine utilizes the strong oxidizing property of ozone to oxidize some bacteria and microorganisms.

2, ozone household vegetable cleaning machine harm

The Ozone Industry Association develops health standards:

International Ozone Association Health Standard: 0.1ppm

American Health Standard: 0.1ppm

German, Japanese, French and other national health standards: 0.1ppm

Chinese health standard: 0.15ppm

When the concentration is 0.15ppm, it is the olfactory threshold, which can be smelled by ordinary people and is also a hygienic standard point. That is to say, when it can be smelled, it exceeds the standard of hygiene: it will cause poison to the human body:

1 It strongly stimulates the respiratory tract, causing sore throat, chest tightness and cough, bronchitis and emphysema.

2 Ozone can cause human neurotoxicity, dizziness, headache, decreased vision, and memory loss.

3 Ozone can also block blood oxygenation, causing tissue hypoxia.

4 impaired thyroid function, bone calcification, can also cause potential systemic effects, such as induced lymphocyte chromosome aberrations, damage the activity of certain enzymes and produce hemolysis reaction.

5 Ozone also destroys the body's immune function, induces chromosomal lesions of lymphocytes, accelerates aging, and causes pregnant women to have deformed children.

6 Ozone can damage vitamin E in human skin, causing wrinkles and dark spots on human skin.

7 The high voltage (several kV ~ tens of kV) electric field generated by corona discharge during the ozone burning process of household vegetable washing machine can not only excite oxygen to generate ozone, but also have enough energy to stimulate the production of nitrogen oxides.

Nitrogen oxides include various compounds such as nitrous oxide (N2O), nitric oxide (N0), nitrogen dioxide (NO2), dinitrogen tetroxide (N203), dinitrogen tetroxide (N204) and five. Nitrous oxide (N205) and the like. Except for nitrogen dioxide, other nitrogen oxides are extremely unstable. When exposed to light, humidity or heat, they become nitrogen dioxide and nitrogen monoxide, and nitric oxide becomes nitrogen dioxide. Nitrogen dioxide is classified as a carcinogen by the US Food and Drug Administration.

The World Health Organization's International Agency for Research on Cancer has determined that there is sufficient evidence that bromate can cause cancer in laboratory animals, so bromate is classified as a substance that may be carcinogenic to humans. The US Environmental Protection Agency and Health Canada also list bromate as a substance that may be carcinogenic to humans.

2. Analysis of the effect of ozone household vegetable washing machine

1Ozone concentration determines the effect of good or bad

The higher the concentration of ozone, the stronger his oxidizing properties. When oxidizing bacteria and microorganisms, it also oxidizes water, vegetable and vegetable meat, which causes the molecules of vegetables and meat to react and thus lose nutrients.

2 purchase ozone household vegetable washing machine precautions

Because there are many kinds of ozone household vegetable washing machines on the market, the functions may be different. Before you buy the ozone household vegetable washing machine, you should check the ozone concentration of the ozone machine and whether the ozone household vegetable washing machine will cause people to work. Negative harm.

Household vegetable washing machine summary:

1 Ultrasonic household vegetable washing machine uses pure physical methods to clean fruits, vegetables, meat and other items, and determines whether the ultrasonic household vegetable washing machine is effective mainly depends on the ultrasonic power of his work.

2 Ozone household vegetable washing machine uses the chemical method of strong oxidizing ozone to clean fruits, vegetables, meat and other items. The key to determining whether ozone household vegetable washing machine is effective is the concentration of ozone (but pay attention to his side effects and hazards). ).
