The invention discloses a rice bran oil degreasing method by adding crystal nucleuses. The method is mainly characterized in that a production process that activated carbon is used as the crystal nucleuses to remove rice bran grease is adopted. Investment on devices is reduced, the appearance color of oil is improved, the oil flavor is increased, and oil quality is improved.
Description
Technical field
The present invention relates to a kind of method that Rice pollard oil adds nucleus degreasing.
Background technology
In Rice pollard oil, fat is more, general pressed oil can not add nucleus freezing and crystallizing and can degreasing filter, also have first freezing formed brilliant intercalation after add that diatomite making coatings carries out filtering, but these ways are some disadvantage all: do not add crystal grain when nucleus filters softer, can not be too fast in filtration hourly velocity, not so oil circuit blocks, make oily filtration velocity slower, when oily filtration velocity is crossed slow, the oil leached can not take away the heat that filter frame heat is delivered to oil in time, frame can be made to freeze esterified one-tenth oil leach, thus affect the quality of processed oil, even make filtration process failure; If add diatomite after crystallisation, can pick up speed filter, but the smell of some deodorised oil can not remove, also add because of diatomaceous the yield that have impact on oil.
Summary of the invention
A kind of Rice pollard oil is the object of the present invention is to provide to add the method for nucleus degreasing.
Technical scheme of the present invention is: a kind of Rice pollard oil adds the method for nucleus degreasing, it is characterized in that: comprise the steps: 1. to treat that pressed oil is lowered the temperature, and adopts oil temperature in crystallizer of the de-ester that first dewaxes again to drop to 30-35 DEG C; 2. in premixing tank, add activated carbon and the oil of oil mass 0.3-0.5%, with recycle pump add agitator circulation stirring evenly after pump in crystallizer, stir; 3. cooling is continued, maintenance cooling rate 1 DEG C/time, final temperature 3 DEG C; 4. oil temperature 3 DEG C is kept, growing the grain 24 hours; 5. processed oil is filtered out with diaphragm pressing machine; 6. after filter filter completely, change roily oil pond into, more evenly slowly add pressurized air by fuel-displaced in diaphragm plate, adjustment intake velocity, until the fuel-displaced one-tenth in oil strain hole drips and per minute about ten, stops press filtration; 7. filter cake is discharged into dewaxing groove, after filter mates, then produces filtration; 8. pass into hot water indirect heating fat in dewaxing groove, fat temperature reaches 50 DEG C and pumps in flame filter press after wholeization fat, with filter-cloth filtering except activated carbon in degrease, leaches oil and after cloth envelop collector polishing, enters fat tank again; 9. when flame filter press oil strain speed obviously reduces, fuel charging valve and plate side delivery valve are closed, from opposite side enter heat treat de-ester oil, activated carbon and rich mixture are discharged from filter oil-in, after activated carbon obviously reduces, open frame oil drain valve, discharged by Residual oil activated carbon in frame, activated carbon and rich mixture are incorporated to bleaching process.
Activated carbon of the present invention is wooden activated carbon, weight loss on drying≤10%; Muriate≤0.2; Heavy metal≤0.01%, potential of hydrogen pH value 2.0-5.0; Granularity 180-200 order; Caramel decolouring >=100%, molysite≤0.1%; Meet GB/T13803.3-1999 standard.
Diaphragm pressing machine of the present invention is 2 200m
2diaphragm pressing machine.
Flame filter press of the present invention is the flame filter press of cloth bag band heating coil.
The present invention, compared with traditional technology, has the following advantages: can reduce facility investment.Old technique adopts 4 200 ㎡ diaphragm pressing machines to filter, and could meet the turnout of 120 tons/day, and now with 2,2 that are left are used for alternative Winterization filter and dewax filtration.Improve grease appearance luster.Activated carbon does nucleus degreasing, and can reduce a look red.Increase grease local flavor.Make with activated carbon the fishy smell that nucleus degreasing can improve de-ester oil, make Rice pollard oil have gas flavour own purer more fragrant.
The present invention's activated carbon is made nucleus activated carbon and is made nucleus degreasing process and can accelerate grease filtrating speed, reduces equipment investment cost, and increase grease local flavor, improving grease color, is the good technique be worthy to be popularized.Its effect analysis is as follows:
Accompanying drawing explanation
Fig. 1 is present invention process schema.
Embodiment
Embodiment 1
Get pressed oil 500 grams (yellow 35 red 6) under experimental conditions, the activated carbon adding 2.5 grams (0.5% of oil mass) at 30 DEG C stirs, within 24 hours, be slow cooling to 4 DEG C (falling 1 DEG C by refrigerator is per hour), and keep 4 DEG C of 10 hours growing the grains, rear taking-up sample filter paper is incubated filtration in the refrigerator of 4 DEG C, get the edible vegetable oil filtered and do 0 DEG C of test, can keep not freezing for 8 hours, and color and luster (yellow 35, red 5), gas flavour is purer than crude oil, does not have the bilgy odour of deodorised oil, and 280 DEG C of heat test blue valves do not increase.
Embodiment 2
Concrete production craft step of the present invention is as follows:
1. the grand temperature of pressed oil is treated.Adopt the oil of the de-ester that first dewaxes again, when temperature drops to 35 DEG C in crystallizer.
2. add in premixing tank 0.3% of oil mass activated carbon (gac purchased from the wood activated charcoal of Hunan factory, weight loss on drying≤10%; Muriate≤0.2; Heavy metal≤0.01%; Potential of hydrogen (pH value) 2.0-5.0; Granularity 180-200 order; Caramel decolouring is more than or equal to 100%; Molysite≤0.1%; Meet GB/T13803.3-1999 standard.), then add half ton of oil, after even with recycle pump+agitator circulation stirring, pump in crystallizer, stir.
3. cooling is continued, maintenance cooling rate 1 DEG C/time, final temperature 3 DEG C.
4. oil temperature 3 DEG C is kept, growing the grain 24 hours.
5. filter.Filter with 2 200 ㎡ diaphragm pressing machines, output can reach 120 tons/day.Filter fuel-displaced muddiness during beginning, roily oil squeezes into crystallizer crystallization again; In time going out the bright nothing of edible vegetable oil and hang cloud, go out processed oil.
6., after filter filter completely, change roily oil pond into by fuel-displaced, more evenly slowly add pressurized air in diaphragm plate, adjustment intake velocity, requires in one hour from 0MPa to 0.8MPa, keeps pressure 0.8MPa20 minute, until the fuel-displaced one-tenth in oil strain hole drips and per minute about ten, stop press filtration.
7. filter cake is discharged into dewaxing groove, after filter mates, then produces filtration.
