Everyone is living well today. Eating any food and vegetables are about organic and healthy. Most of the vegetables and fruits we buy in the market have pesticides. Our daily cleaning is difficult to clean. So, many families have bought fruit and vegetable washing machines. What is the principle of the fruit and vegetable washing machine?
Ozone disinfection.
Ozone cleaner is the most common type of vegetable washing machine. Ozone is a strong oxidant. It can destroy the structure of pesticides and degrade them. It is good at removing easily oxidized pesticide residues. But it spends much time in removing pesticide residues. The experiment shows. And the requirements for ozone density are relatively high. Household ozone cleaners cannot meet the test standards. Whether it is ozone density or working hours.
The anti-virus principle of the ozone cleaner. It uses ozone to decompose pesticide ingredients. Its effect is closely related to ozone's density and quality. Ozone with a density of 4 mg/L removes 60% to 70% of organophosphorus pesticides in 30 minutes. This requires a large ozone instrument. Not a household vegetable washing machine. Judging from the current market situation. Ozone cleaner has limited gas production. The conversion rate of ozone to water is low. The general density is only 0.1 mg/liter to 0.2 mg/liter. It is conceivable to decompose pesticides. It is good to remove 10% to 20% of pesticide residues on fruits and vegetables. Ozone treatment may affect the nutritional composition of some leafy vegetables. Treat pakchoi with ozone water. It will lose near 30% of total vitamin C. A study shows.
The more important point. Residual pesticides are degraded to produce small molecules. Its harmfulness has not yet been risk assessed. The risks of these substances may be higher than pesticide residues. Due to the wide variety of pesticides. Ozone is not effective in removing all pesticide residues. The promotion of the business is only for specific situations.
Plasma technology is used to remove pesticide residues from fruits and vegetables. This is a big selling point for various businesses. What is the working principle of machine with plasma disinfection function?
Plasma disinfection is low-temperature disinfection. It uses a plasma generator. To separate electrons from atomic nuclei. Then presenting the "ionic state". In general, the positive and negative charges are still equal. So, it's called "plasma". This is another form of matter besides common solids, liquids and gases. Heavy use of plasma in modern industry. It has the ability of "low temperature sterilization". And It has been widely used in many places. Especially in places where high temperature sterilization is inconvenient. Such as air disinfection, medical equipment sterilization. But it is difficult for plasma to leave pesticide residues. The Experiments show.
There are many kinds of fruit and vegetable washing machines on the market. Consumers need to compare more and choose the right product. Give our health more protection.
