Description
Technical field
The utility model relates to a kind of devices using UV treatment wheat berry.
Background technique
Nineteen sixty, Britain lead to the poisoning of 100,000 turkey young baby's death, find out it is since turkey eats later
Caused by feed containing mildew peanut cake, and thus have found that aflatoxin.From this mycotoxin contamination problem in 20 generation
It records and has caused the most attention of every country and area the sixties.In China and in the world other areas, mycotoxin is to food
Very universal with the pollution of feed, either agricultural product or livestock products all can be by the harm of mycotoxin.
The summer and autumn of China's crop harvesting, the duration in rainy season is long, with the humid air, is very beneficial for the life of mould
It is long, therefore the mycotoxin contamination problem in China is very serious.Mycotoxin seriously damages animal body and then influences people
Health, the prevention and detoxification of mycotoxin are industry focus of interest all the time.Mycotoxin type is more, right
The toxic action of animal and human body is different, and aflatoxin B l, vomitoxin are universal in the pollution of China crops and feed
In the presence of.In practical applications, mould inhibitor is widely used.Mould inhibitor main purpose is the mycostatic growth of suppression, prevents mould poison
The generation of element.For the feed of contaminated mold toxin and crops, the method for solution is less.
For wheat berry, aflatoxin B1, vomitoxin are mainly stored in the bran coat of wheat berry, aspergillus flavus
Toxin B1 has the characteristics that heat-resisting, heats and is not also destroyed at 100 DEG C for 20 hours, only just splits in the high temperature of 270 DEG C of 0C or more
Solution, DON heated at 100 DEG C and 120 DEG C 1 hour it is still very stable, 170 DEG C of heating 15min are partially destroyed.Add so being difficult to use
The method of heat removes toxicity.
Current international and national is retrieved to the removal research of aflatoxin B1, vomitoxin in wheat berry not as good as other
Agricultural product product, especially in using green physical method removing wheat berry in terms of aflatoxin B1, vomitoxin, base
Originally belong to blank.The wheat for selecting suitable poison-removing method to pollute mycotoxin carries out detoxification, can reduce mycotoxin
Level of pollution reduces toxin and endangers caused by animal and the mankind.Common poison-removing method has: physics poison-removing method, including water
Wash method, scalping method, de- embryo detoxification method, solvent extraction method, heating detoxification method, radiation method, adsorbent absorption method etc.；Chemical detoxication side
Method, including acid processing, alkali process and add other chemical substance treatments etc.；Biological detoxification method mainly utilizes microorganism
Itself or its enzyme generated degrade to mycotoxin.Most common method is that mold toxin sorbent is added in daily ration.
These methods require to be added certain substance in wheat berry, be easy to cause secondary pollution, in addition, be added substance there is also
The problem how to remove.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of devices using UV treatment wheat berry, pass through
The present apparatus can reduce wheat berry aflatoxin B1, the content of vomitoxin.
In order to solve the above technical problems, the utility model provides a kind of device using UV treatment wheat berry, packet
Include the reactor tank of vertical arrangement and upper lower sealing, in reactor tank equipped with it is horizontally disposed and between the upper and lower every the first plate, the second plate, the
Three plates, what first plate, the second plate were all made of is the sieve plate of 60 mesh, the third plate be equipped with it is several along vertically to
Through the stomata of third plate, the stomata is arranged on third plate in determinant, and the diameter of stomata is 2cm, every row or every
The center of two stomatas of arbitrary neighborhood corresponds in reactor tank sidewall locations away from for 20cm and is equipped with one at third plate lower part in column
The pipeline being connected to inside and outside reactor tank, the pipeline are connected far from the side of reactor tank with compressed gas source, reactor tank sidewall locations

Fluorescent tube is parallel with one another and connects external power supply by controller.
For the sake of simple declaration problem, below to a kind of dress using UV treatment wheat berry described in the utility model
It sets and is referred to as the present apparatus.
The application method of the present apparatus are as follows: the present apparatus first selects the ultraviolet tube of 254nm wavelength and the gas source of compressed air,
Keeping ultraviolet light average radiation luminous intensity by controller is 320mJ/cm2, stablize 3-5min；By wheat berry to be processed from filling out
Material mouth is put on the second plate, is then turned on compressed air gas source, and wheat berry is made to keep rolling between the first plate and the second plate
State takes out wheat berry after handling 10-15min；Then change the outfit the ultraviolet tube and pure oxygen compressed gas source of 185nm wavelength, leads to
Crossing controller and keeping ultraviolet light average radiation luminous intensity is 150mJ/cm2, stablize 3-5min；It then again will be by first processing
Wheat berry be put on the second plate from feeding port, open pure oxygen compressed gas source, protect wheat berry between the first plate and the second plate
The state of rolling is held, takes out wheat berry after handling 10-15min.
Ultraviolet photolysis technology, which refers to, occurs organic pollutant structure under irradiation of the substance in the ultraviolet light of specific band
Isomerization or chemical bond occur fracture and reset and generate new compound, to reach decomposition or remove removal organic polluter mesh
A kind of technology.The first step first uses the ultraviolet light of 254nm wavelength to the aflatoxin B1 on wheat berry surface and vomiting poison
Plain strand is decomposed, its macromolecular structure is smashed and becomes small molecule structure.Wheat embryo in wheat berry is rich in lipid,
Be easy to generate aflatoxin B1, vomitoxin be since wheat scab causes, the aflatoxin B1 in wheat berry
And vomitoxin is mostly present in the surface of wheat berry, since the ultraviolet light of above-mentioned 254nm wavelength is to the Huang on wheat berry surface
Aspertoxin Bl and vomitoxin strand are decomposed, and are only smashed its macromolecular structure and are become small molecule structure.It generates
Object is difficult to determine its ingredient, so second step uses the ultraviolet light degradation oxygen molecule of 185nm wavelength to generate free oxygen again, i.e., it is active
Oxygen, so need to be in conjunction with oxygen molecule because of the taken positron-electron imbalance of free oxygen, and then generates ozone, and ozone further aoxidizes small
The small-molecule substance that the aflatoxin B l and vomitoxin on wheat surface are generated in first step processing, generates harmless CO2、
H2O etc..Aflatoxin B1 and vomitoxin are further removed simultaneously.In order to improve efficiency, replaced using pure oxygen compressed gas source
Air compressed gas source improves ozone concentration, the irradiation intensity and irradiation time of high energy ultraviolet is reduced, to not destroy wheat berry
The physicochemical property of internal endosperm.
The advantages of present apparatus: present apparatus structure is simple, easy to use, by the quartz burner of different wave length and different
Intensity of illumination handles wheat berry twice, can reduce wheat berry aflatoxin B1, the content of vomitoxin.It can meet
Wheat flour in " mycotoxin is limited the quantity in national food safety standard food " (GB2761-2011) food: aflatoxin B1 limit
The relevant criterion that figureofmerit is 5 (μ g/kg), vomitoxin limit index is 1000 (μ g/kg).
To reach the better using effect of the present apparatus, preferred embodiment is as follows:
Preferably, the ultraviolet tube be strip, and ultraviolet tube along its width direction it is equidistant between
Every arrangement.
The ultraviolet tube of equidistant interval arrangement can guarantee more uniform intensity of illumination.
