Description
Technical field
The present invention relates to fats and oils processing refining techniques field, and in particular to the refining of the poisonous factor in a kind of reduction corn oil
Method.
Background technology
Bread is the staff of life, and vegetable fat quality and safety control is promising important, phenylpropyl alcohol ratio especially in plant, aspergillus flavus,
Red enzyme ketenes, the volt poisonous factor content such as agate toxin number, body, life security concerning consumer.Raw corn oil is because having
Malicious factor species is more, raw corn oil by product oil part after conventional degumming, alkali refining, decolouring, four operations of deodorization it is poisonous because
Son may surpass GB (especially red enzyme ketenes, volt agate toxin), but such as by degumming alkali refining, decolouring, dewaxing, double tower dual temperature twice
Four operations of deodorization, poisonous factor content will be less than GB or reach EU criteria (especially red enzyme ketenes, Fu Ma in product oil
Toxin).To adapt to these requirements, oil refining process technology must grow with each passing hour, and constantly update.
The content of the invention：
The technical problems to be solved by the invention are to provide to reduce the poisonous factor in product oil, and preparing corn oil has taste
The method of refining for reducing the poisonous factor in corn oil of vigorous and graceful health, comprehensive nutrition,
The technical problems to be solved by the invention are realized using following technical scheme：
The method of refining of the poisonous factor in a kind of reduction corn oil, it is characterised in that comprise the following steps：
1) alkali refining：1000 parts of raw corn oil elder generation removal of impurities is taken, the 80-85 DEG C of phosphoric acid with 1.3 parts is heated to and is mixed
After stopping 60-70 minutes, then carry out mixing 2-3 minutes to enter into the first desk centrifuge with 22.34 parts of the liquid caustic soda of 18-20 Baume degrees
The de- soap of row, de- soap oil again with 22.34 parts of the liquid caustic soda of 8-10 Baume degrees, mix 15-20 minutes；
2) secondary alkali refining：Material after step 1 is processed puts into the second desk centrifuge and is taken off soap, Ran Houhe again again
The 3rd desk centrifuge is entered into after 50 parts of hot water, 0.58 part of citric acid mixing to be washed, then enter back into drier
Row drying, bleaching process is entered after drying；
3) decolourize：It is white with 24 parts by dry oil dried in above-mentioned steps 2 after being further heated to 105-110 DEG C
Soil, 1.9 parts of activated carbons, 7.25 parts of filter aid mixing carry out oily soil blending tank, enter back into bleaching tower, and 20-30 points is stopped in tower
Clock, be transported in filter filtered, be cooled to 45-50 DEG C after enter into dewaxing operation.
4) dewax：45-50 DEG C in above-mentioned steps 2 of decolouring edible vegetable oil is entered into dewaxing operation：Decolouring edible vegetable oil is through further
Heat exchange, after temperature reaches 23-27 DEG C, is mixed into oily soil blending tank with 3.85 parts of diatomite, and mixture passes through delivery pump
It is delivered in crystallizing tank, gradient heat exchange is carried out in crystallizing tank by refrigerator chilled water, oil is cooled to 5 DEG C in 16 hours
Crystallized；The decolouring edible vegetable oil temperature of advantages of good crystallization maintains 5 DEG C, starts to stand growing the grain 10-12h；The good decolouring edible vegetable oil of growing the grain, passes through
It is delivered to after precoating tank, 1.5 parts of diatomite is then added again, is then input to horizontal blade circulation, is applied to oil in advance clearly；Into
In dewaxing edible vegetable oil tank, deodorization procedures are transported to.
5) double tower dual temperature deodorization：By the dewaxing edible vegetable oil in above-mentioned steps 3 through further heat exchange, temperature reaches 60 DEG C through entering one
Step is heated to 95 DEG C, and subsequently into deodorization procedures gassing tank, a step enters tray column after being heated to 230-235 DEG C, in plate
Shi Tanei is stopped 60-80 minutes, is heated to 245-250 DEG C and is entered into filler extracting tower, stops to go out for 20-30 minutes in tower
Tower, less than 30 DEG C are cooled to through heat exchange, then are carried out filtering by bag type filter and entered finished pot, are taken comprehensive sample and are chemically examined qualified
The storage of input reservoir area.
The beneficial effects of the invention are as follows：The advanced novelty of present invention process, multiple alkali refining and double tower dual temperature deodorizing technology, it is ensured that
Pilot process product quality is received in controllable state, it is often more important that greatly reduce containing for the poisonous factor in corn primary oil
Amount, it is ensured that the cleaning and heath of corn oil, comprehensive nutrition.
