These features of the present invention and advantage will be detailed in following specific embodiment exposure.
【Brief description】
The present invention is described further below in conjunction with the accompanying drawings：
Fig. 1 is the structural representation of the present invention.
【Specific embodiment】
A kind of method going pesticide residues that the present invention provides, comprises the following steps：
(1) prepare degradation agent, the degradation agent of preparation includes 20%-25% potato starch, 1.2%- by percent mass hundred
2.5% persulfate, 0.2%-1.4% nano titanium oxide, 1.5%-3.2% potassium selenite, 15%-25% ferrate,
Remaining is water；Wherein ferrate has excellent sterilization effect, and ferrate can effectively remove organophosphors using potassium ferrate
Pesticide, nano titanium oxide has good photocatalysis performance, and it can absorb luminous energy, produces and has the material of strong oxidizing property to drop
Chemical bond in solution pesticide.Persulfate can be sodium peroxydisulfate, potassium peroxydisulfate or Ammonium persulfate., is oxidizing species.Sub-
Selenium in potassium selenate can quickly enter plant cell in photosynthesis, adds the foreign substance removing function of cell, accelerate pesticide to divide simultaneously
The aging and fracture of subchain, substantially reduces the pesticide residues in crops.
(2) vegetables and fruits are put in microwave device, 20 times -25 times of dilution agent of degraded adds in microwave device afterwards, microwave device
Power 30W～50W, extraction time is 20min～30min；Fully degraded by the pesticide that microwave device makes residual in vegetables and fruits.
(3) vegetables and fruits in microwave device are taken out and put in cleaning machine, and to infusion fluid carbon dioxide in cleaning machine.Two
Carbonoxide, no bromine are tasteless, do not burn.Due to the unique safety of carbon dioxide, avirulence, it is referred to as green bio separation skill
Art.Supercritical fluid carbon dioxide fluid has very high solvability.Particularly with fat-soluble material, can be by non-pole
The carbon dioxide of property dissolves removing effectively.This technology is to make dissolving more thorough, and it is residual operatively to dissolve agriculture, and will be desorbed
The residual residual concentration of agriculture being moved out to separating still, reducing separating still dissolving scene of agriculture, so circulation can be by residual for agriculture effective removing.
With reference to Fig. 1, the cleaning machine of employing includes body 1 and the driving means 6 being arranged on body 1, and body 1 is provided with interior
Room 11, interior room 11 has cylinder 2, to water filling in cylinder 2 waterflood path 4 and for draining drainage channel 5, cylinder 2 interior
Wall is provided with the convex tendon 21 that spiral rises, and driving means are used for driving cylinder 2 intermittent rotary, interior room 11 is hung with positioned at cylinder 2
In washing tube 8, the side wall of washing tube 8 is provided with sieve aperture 81.The vegetable or fruit that need cleaning are put into washing tube 8, note
Aquaporin-4 is flowed in washing tube 8 to water filling in cylinder 2, water through sieve aperture 81, and then driving means 6 drive cylinder 2 to rotate,
Driving cylinder 2 to rotate makes the water in cylinder 2 and washing tube 8 rotate, and being combined with of convex tendon 21 strengthens the effect that current rotate centrifugation,
Thus effectively cleaning vegetable or the fruit in washing tube 8, after the completion of cleaning, sewage being discharged from drainage channel 5, finally taking out and washing
Wash the vegetable in bucket 8 or fruit.The present invention, in cleaning process, directly will not produce to vegetable and fruit and clash into, keep vegetable
Complete with fruit, there is excellent cleaning performance.The driving means 6 preferably employing are motor.The rotating speed of its intermediate roll
For 600r/min～8000r/min
Kickboard 9 is also installed in washing tube 8, the side wall of washing tube 8 is provided with guide rail 82 along short transverse, kickboard 9 sets
There is the chute with guide rail 82 cooperation.Driving means drive cylinder 2 intermittent rotary, and cylinder 2 rotates and makes in cylinder 2 and washing tube 8
So that kickboard 9 rises during water centrifugation rotation, drive and move on vegetable and fruit above kickboard 9, cylinder 2 stops operating
Afterwards, under Gravitative Loads, veterinary antibiotics and kickboard 9 move down, and can make separating sundries in this process, strengthen cleaning performance.
Wherein, the top of cylinder 2 is provided with bearing 3, and bearing 3 is provided with the hook connecting washing tube 8, and body 1 is provided with drive
The lift cylinder of dynamic bearing 3 lifting.Lift cylinder drives bearing 3 to drive washing tube 8 to lift, and is easy to take out washing tube 8, thus
By under the vegetable in washing tube 8 or fruit unloaded.
In vegetable fruit and vegerable, excessive sulfur dioxide residue is big to the harm of human body, needs the method desulfuration rinsing by heating,
Heating steam pipe 7 is therefore connected with cylinder 2, heating steam pipe 7 stretches into the bottom of cylinder 2.If heating steam pipe 7 is provided with
Do pore, heating steam pipe 7 inputs the cold water in steam heating water tank.
Hairbrush can be set in the side wall of washing tube.Vegetable or fruit with during current rotation with hairbrush friction, effectively dispel
Except the debris on vegetable and fruit.
By above-described embodiment, the purpose of the present invention is reached by fully effective.One of ordinary skilled in the art
