According to the method, the adopted ozone water is high-concentration ozone water prepared by the low-voltage electrolysed water, the preparing process is simple, the by-product generated in the ozone water preparing process is oxygen, pollution caused by nitrogen oxide is avoided, the cleaning, disinfection and pesticide removal effects are good, the water for cleaning can be recycled, and water consumption is reduced.
Description
Background technology
The present invention relates to the cleaning method of fresh fruit of vegetables, be specifically related to a kind of method utilizing water Ozone Water to clean fresh fruit of vegetables.
Background technology
Traditional fruits and vegetables ozone clean machine, it is raw material that its Ozone Water derives from air, produced through high-frequency and high-voltage corona method.Although the Ozone Water that this machine produces has certain effect for aspects such as fruits and vegetables cleaning, sterilizations, but, following shortcoming is still had for Ozone Water: one is using air or pure oxygen as raw material, need through the pretreatment such as freezing, dehumidifying, drying, absorption, and technique, equipment are complicated with this legal system.Two is when high-frequency and high-voltage ionizes, and is that ozone prepared by raw material with air, inevitably produces the pollution of accessory substance nitrogen oxide.The existence of nitrogen oxide, not only contaminated air, also increase food safety risk, is detrimental to health.Take pure oxygen as raw material when preparing ozone, the equipment such as the additional oxygenerator of needs are many.Three is that ozone concentration is low, mostly within 0 mg/litre-5 mg/litre, cannot meet the aspects such as cleaning, sterilization, removal agriculture be residual to the demand of a large amount of high-concentration ozone water, the limited efficiency that cleaning, sterilization and removal agriculture are residual.Four is adopt high-frequency and high-voltage alternating current (between several kilovolts of-several ten thousand volts) to prepare ozone, and circuit is complicated, poor stability.Five is high frequency voltage, high-voltage pulse generation discharge noise and electromagenetic wave radiation, forms noise and Contamination of Electromagnetic Wave.Six is have ozone gas to escape in air, affects health.Seven is that the consumption of water for cleaning is large, is not recycled.
Summary of the invention
Technical problem to be solved by this invention is: in conventional art with the above-mentioned problems that air or pure oxygen exist for the preparation of the Ozone Water of cleaning fruits and vegetables for raw material, a kind of water Ozone Water is provided to clean the method for fresh fruit of vegetables, the method by that to take pure water as raw material be used for the cleaning of fresh fruit of vegetables, sterilization and removal agriculture by the Ozone Water that low-voltage electrolysis produces is residual, to improve the residual effect of fruits and vegetables cleaning, sterilization and removal agriculture.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of method of water Ozone Water cleaning fresh fruit of vegetables, be characterized in, the method continues to join in the clear water of the cleaning fresh fruit of vegetables of 5-35 DEG C by the high-concentration ozone water that low-voltage electrolysis water produces, the ozone concentration in the cleaning Ozone Water of cleaning fruits and vegetables is made to maintain 0.5-10 mg/litre, again the fresh fruit of vegetables clean through clean water is put in cleaning Ozone Water and soak 5-30 minute, fruits and vegetables are taken out, drain away the water, wherein, the mass ratio of the fresh fruit of vegetables of cleaning Ozone Water and input is 2:1-10:1.
Preferably, the ozone concentration in above-mentioned cleaning Ozone Water maintains 5-5.5 mg/litre.
Preferably, the mass ratio of the fresh fruit of vegetables of above-mentioned cleaning Ozone Water and input is 4:1.
Preferably, the clear water temperature of above-mentioned cleaning fresh fruit of vegetables is 10-30 DEG C.
The above-mentioned ozoniferous technology of low-voltage electrolysis aquatic products mentioned take pure water as raw material, take PEM as barrier film, under the effect of low pressure Electric Field, make water lose electronics in special anodic interface be oxidized to ozone, for prior art, as existing low-voltage electrolysis formula PEM ozonizer generates ozone, do not repeat them here.
In this application, the cleaning Ozone Water of cleaning fresh fruit of vegetables in said method comprises overflows part by supplying after collection to prepare high-concentrated ozone water circulation use.
Operation principle of the present invention: adopting with pure water is that Ozone Water prepared by raw material is cleaned fresh fruit of vegetables, eliminates nitrogen oxides pollution; The Cleaning principle of water Ozone Water: the strong oxidation relying on ozone, oxidizes away the dirt of fruit and vegetable surfaces, then rely on water to clean up; The sterilizing mechanisms of water Ozone Water: the strong oxidation relying on ozone, makes microorganism deactivated; Water Ozone Water removes the residual principle of agriculture: the strong oxidation relying on ozone, makes remains of pesticide oxidation Decomposition, then rely on water to clean up.
Compared with prior art, the present invention has the following advantages: one be the Ozone Water that the inventive method adopts is the Ozone Water prepared with low-voltage electrolysis water, and preparation technology is simple.Two be with pure water preparation accessory substance that Ozone Water produces for oxygen, there is no the pollution of nitrogen oxide.Three is according to the requirement of different application, can adjust the concentration of ozone ozone in water, to meet the needs of different application to high-concentrated ozone, and cleaning, sterilization and residual effective of removal agriculture.Four is adopt low-voltage DC (3 volt of-4 volt), and circuit is simple, safety; Five is low-voltage DC noiseless, pollutes without electromagenetic wave radiation.Six is that water for cleaning is recycled, and reduces the consumption of water.
