Are the fruit and vegetable washing machine reliable
At present, the fruit and vegetable washing machines on the market are divided into three categories, which are also the generations of a technology update. They are the 1.0 era – ozone type fruit and vegetable washing machine; 2.0 era – ultrasonic type fruit and vegetable washing machine; 3.0 era – plasma type fruit and vegetable washing machine. Then take a look at the detailed working principle of these three types of fruit and vegetable washing machines!
1.0 era – ozone type fruit and vegetable washing machine
Ozone sterilization fruit and vegetable washing machine principle: Ozone is unstable under normal temperature and normal pressure, and will decompose into oxygen and a single oxygen atom by itself; and the oxygen atom has strong activity, which has strong oxidation effect on bacteria and eliminates it. The excess oxygen atoms will recombine themselves into ordinary oxygen atoms, and there is no toxic residue, so it is called a pollution-free disinfection machine. Therefore, when the fruit and vegetable washing machine is operated, the ozone generator generates ozone, which is transported by the ozone pump through the ozone tube to the washing tub of the vegetable washing machine, contacts the water machine in the washing tub, dissolves in the water to form ozone water, and achieves sterilization and disinfection. Degrading pesticides, hormones and removing residual substances from the surface of the food.
Ozone is irritating to the human respiratory tract mucosa; ozone is a strong oxidant. The higher the concentration, the more serious the damage to the article, which can cause green rust spots on the copper sheet, aging of the rubber, discoloration, and reduced elasticity, resulting in brittleness and breakage, and bleaching and fading of the fabric. Therefore, care should be taken to avoid the ozone disinfection of these items. Also, keep the machine as far away as possible, and remember to keep the machine out of the reach of children when not in use.
However, the current fruit and vegetable washing machines on the market do not use this technical method, mainly because ozone damage is relatively large, but there are still some fruit and vegetable disinfection machines still using this principle to disinfect.
2.0 era – ultrasonic fruit and vegetable washing machine
Ultrasonic cleaning and sterilization of fruit and vegetable washing machine principle: The sudden change of sound pressure when ultrasonic waves propagate in liquid causes strong cavitation and emulsification of liquid, generating millions of tiny cavitation bubbles per second. These bubbles are rapidly under the action of sound pressure. The ground is produced in large quantities, and it does not violently blast, which produces a strong impact force and negative suction force, which promotes the peeling of the dirt and achieves a cleaning effect.
Disadvantages: Ultrasonic itself does not have a sterilization function. Under normal circumstances, ultrasonic cleaning and sterilization fruit and vegetable washing machines are usually equipped with an active oxygen generator to complete the sterilization effect, and the cost is relatively high. This is also because ultrasonic technology is more widely used in industry, suitable for the cleaning of some particularly small products with high requirements for cleanliness such as watches and precision machinery parts, electronic components, circuit board components. At the same time, the noise pollution during ultrasonic cleaning is heavier.
3.0 era – plasma fruit and vegetable washing machine
The principle of plasma sterilization fruit and vegetable washing machine is to use water treatment technology to accelerate the activation of oxygen and hydrogen ions, convert them into plasma form to produce hydroxyl groups, and decompose, disinfect and purify organic and non-organic substances under non-thermal low-temperature conditions. Leave harmless by-products such as water and water vapor.
Advantages: rapid sterilization, high-efficiency degradation of pesticide residues, hormones, antibiotics; no added, no escape, no residue, efficient and safe, green and environmentally friendly.
At present, the most popular fruit and vegetable washing machines on the market are ozone type and an ultrasonic type. However, as the technology is updated step by step, people have put forward more requirements for this. Environmental protection and health, plasma sterilization technology fruit and vegetable washing machine meet everyone’s needs. At present, there are not many manufacturers using this technology on the market, such as food safety, bingo, high, etc. In comparison, the effect of food and vegetable cleaning machine is better, but the price is around 7K, the cost performance is better. low. The same technology of bingo food purification machine price of more than 2K, better purification effect, German quality, cost-effective. The high-quality food purifier is less than 2K, which increases the voice function and is more cost-effective for the elderly. Of course, there are many selection factors such as capacity, appearance, and cleaning methods. Each household can choose a food purifier according to the actual situation.
