Description
Technical field
The present invention relates to a kind of Apparatus for () and method therefor reducing east of oil, and utilize particularly to one strong
Light irradiates the Apparatus for () and method therefor reducing east of oil.
Background technology
The most refined vegetable crude oil often contain solid impurity, free fatty, phospholipid, colloid, wax,
The impurity such as pigment, can affect the preservation condition of oil product the most simultaneously, therefore need difference for different impurity
Refining procedures purification crude oil, general refining process as filtration, degumming, deacidification, decolouring, deodorize,
Winterization, dewaxing, the step wherein decoloured is to remove such as chlorophyll, phylloxanthin, carotenoid etc.
Natural pigment, generally uses bleaching clay and activated carbon adsorption pigment, and the purpose of deodorize is to remove
The stink caused such as aldehyde, ketone, free fatty etc., typically utilizes the deodorizing tower of high temperature to carry out deodorize,
And the high temperature of deodorize also can destroy natural pigment.
But in refining process, high temperature deodorize can promote harmful trans fatty acid to generate.Typically
In the case of, deodorizing tower, in order to be able to remove more foreign body, can carry out deodorize under the conditions of the deodorize of about 250 DEG C,
In the case of this high temperature, produced trans fatty acid can be ten times under the conditions of 220 DEG C, if but reducing
Temperature, then can make the foreign body that in crude oil, some vapour pressure is relatively low to volatilize, and makes the smoke point of oil product reduce,
The ability removing depigmentation declines the most therewith, therefore to reduce the generation of trans fatty acid, at the same time it is wished that send out
Smoke point and decoloring ability are not deteriorated with the reduction of deodorization temperature, and the most industrial solution taked is
Increase vacuum or extend the time of decolouring, but needed for being to increase vacuum, fund is huge, and extending de-
The smelly time then must reduce flow velocity or increase the volume of deodorizing tower, reduces flow velocity and the production capacity of refine can be made to become
Slowly, make the cost of refine increase, and the volume increasing deodorizing tower can improve the cost of oil refining too and need
Wanting more spaces to set up deodorizing tower, therefore above solution neither synthesizes this.
Additionally, in the case of reducing deodorization temperature, the destruction of natural pigment can be made equally to reduce, industry
Upper solution is to use more bleaching clay or activated carbon adsorption pigment, but can increase cost,
More oil also can be adsorbed, and makes the productivity of refine reduce, the most also can increase the cost of refine.
So, generate trans fatty acid to reduce refining process, it is necessary to reduce temperature during deodorize.So
And, in order to maintain the solution taked under the effect of decolouring and deodorize the most still to have shortcoming, the most how
Reducing temperature, in accordance with cost and maintain in the case of good yield and reach good decolouring and deodorising effect
It it is the problem remained unsolved.
Summary of the invention
Therefore, it is an object of the invention to the principle utilizing natural pigment easily to crack for high light unease,
Purifier adds illumination apparatus with strong illumination vegetable crude oil, replacement bleaching clay or activated carbon
Use, reduce effect of east of oil.
Natural pigment in vegetable crude oil such as Chlorophylls and Carotenoids is natural colour common in plant
Element, there is the porphyrin ring being made up of tetrapyrrole base, therefore presents on absorption spectrum in chlorophyllous structure
The characteristic absorption of meeting porphyrin, therefore chlorophyll a and chlorophyll b are respectively at 420～440nm, 440～460nm
Near have absworption peak, the structure of phytol base then make chlorophyll a and chlorophyll b respectively 635～
Have near 645nm, 655～665nm absworption peak, carotenoid include two quasi-molecules, one be containing only
Hydrocarbon compound, referred to as carotene, another kind is oxygen containing derivant, referred to as phylloxanthin, and class is recklessly
The structure of Radix Raphani element predominantly contains the conjugated structure of eight isoprene, at absorption spectrum 430～450nm
Near have absorption, conjugated structure is very sensitive for oxygen, light.These natural pigment can absorb different wave length
Light, also illustrate that these pigments for just sensitive, and natural pigment is not having other energy to transmit thing
In the presence of matter, easily destroyed by strong illumination.The present invention i.e. make use of the photosensitive spy of natural pigment
Property, purifier is installed illumination apparatus with strong illumination vegetable crude oil, decolouring in replacement decolorization process
Hargil or the use of activated carbon, reduce refining cost and also improve productivity, it is also possible to reduce temperature during deodorize
Degree, reduces the generation of trans fatty acid.And by adjusting the strong illumination of different wave length, can control not
With the reservation of pigment, and then the oil after refine is made to have the pigment and color wanting to retain, additionally, set up
Original purifier need not be revised during illumination apparatus, be greatly saved device update cost.
