Generally 2000-3000 this price, 1000 below there are, but do not recommend to buy; the market ingredients purification machine brands are Sentinel, Hepburn, Time Road, CDE, etc., 1500-5000 this interval is more.
The food purification machine is also known as the food detoxification machine, food detoxification machine is a detoxification treatment of ingredients, to remove pesticide residues on the skin of the ingredients, bacteria, and ingredients within the heavy metals, antibiotics, hormones, plasticizers, and other harmful substances to the human body of the machine.
These ingredients include: meat, seafood, fish, leafy vegetables, stem vegetables, cereals, fruits, shellfish and so on.
The detoxification technologies or similar technologies already available on the market are: high-voltage pulsed electrostatic, ozone, ultrasonic, plasma, high-energy ions, photocatalysts and so on.
Expanded Information:
Classification:
1, high-voltage pulsed electrostatic detoxification
Advantages : The use of high-voltage pulse electrostatic technology, producing tens of thousands of high-voltage pulses per second, changing the balance of substances within the atom itself, the resulting charge impact on the ingredients within the heavy metal harmful particles and produce a strong adsorption effect, the surface of the food and the internal heavy metal particles are adsorbed in the negative electrode wall plate of the instrument, mixing into the water.
At the same time, under the strong electric field, the harmful substances are ionized, generating free radicals, inactivating microorganisms, killing bacteria, and getting rid of pesticides. This technology is also the only one on the market that can be applied to get rid of heavy metals inside ingredients.
Disadvantages: the use of high-voltage electrical energy, the need to use water as a medium, based on the safety of insulation reasons, it is difficult to create a portable form; the other due to the technology is relatively high-end, temporarily failed to popularize a large number of, so the application of this principle of manufacturing instruments cost is relatively high.
2, ozone purification machine
Advantages: ozone at room temperature, atmospheric pressure, the molecular structure is not stable, will decompose into oxygen and individual oxygen atoms; and oxygen atoms have a strong activity, the bacteria have a strong oxidizing effect, will be eliminated.
So when the food purifier operates, the ozone generator produces ozone, which is transported by the ozone pump through the pipeline to the washing drum of the dishwasher, and the ozone is dissolved in the water to form ozone water, which achieves the effect of sterilizing, disinfecting, degrading pesticides and removing residual substances on the surface of food.
Disadvantages: Ozone is irritating to the mucous membranes of human respiratory tract, and it is fatal to the human body when the concentration reaches a certain level; and ozone does not have any effect on removing the heavy metals on the ingredients.
3, ultrasonic purification machine
advantages: ultrasonic propagation of sound pressure in the liquid when the drastic change in the liquid undergoes a strong cavitation and emulsification phenomenon, millions of tiny cavitation bubbles per second, these bubbles in the role of acoustic pressure in large quantities in a hurry, and then burst violently, resulting in a strong impact and negative pressure suction, prompting the stripping of dirt to clean the effect.
Disadvantages: ultrasonic itself does not come with sterilization function, usually, ultrasonic cleaning and sterilization food purification machine is usually equipped with an oxygen generator to complete the sterilization effect, the efficacy is not significant. At the same time ultrasonic cleaning noise pollution is heavy. Ultrasonic cleaning ability is very limited, can not get rid of heavy metals in the ingredients.
4, ionic purification machine
Pros: the use of water treatment technology to accelerate the activation of oxygen and hydrogen ions, they are converted into plasma form to produce hydroxyl, non-thermal low-temperature decomposition, disinfection and purification of organic and non-organic substances, leaving harmless by-products, such as water and water vapor.
Disadvantages: Although ionic purifiers have a stronger disinfecting ability than ozone sterilization, and avoid the negative effects of ozone sterilization, the ionic cleaning ability is weaker, and also unable to get rid of the heavy metals left in the ingredients.
