Abstract
The invention provides a degumming method for edible oil, comprising the steps as follows: crude oil which is just squeezed is heated to 90-110DEG C; diatomite is added in the heated crude oil, sufficiently stirred, mixed and filtrated, thus gaining filtrated oil; the filtrated oil is electrically separated, thus gaining oil with floccule; the oil with the floccule is centrifuged so as to remove the floccule and gain the degumming oil; based on the previous steps, the adding quantity of the diatomite is 0.5-1.5% of the weight of the crude oil. The method can remove the colloid, reduce the phosphorus content to 12ppm, replace the traditional hydrated degumming and acid degumming, save the consumption by 20%, improve the generation speed, reduce the generation cost by 40%, reduce the refining wastewater by 15% at the same time, and protect the ecological environment; the process flow is simple, the production cost is low, the degumming effect is good and the quality of the oil product can be improved.
Description
Technical field
The present invention relates to a kind of edible oil and fat refinery practice, specifically, related to a kind of edible oil degumming method.
Background technology
Vegetable fat is rich in a large amount of peptized impurities, mainly comprises: phosphatide, protein, carbohydrate etc., and phosphatide most importantly wherein, content of phospholipid is generally 1.8% in the oil;
Degumming tech is bigger to the influence of the further refining of grease, if do not remove the colloid in deoiling, will get into trouble when the next process depickling of refining; In the chemical deacidification process of using alkali lye, colloid can cause the emulsification of oil, increases the refining loss of grease; In the physical refining process, because the existence of colloid easily causes the generation of the pot phenomenon of overflowing on the one hand in the decoloration process, bring a lot of troubles to decolorization filtering simultaneously, at high temperature oil colours deepens on the other hand, the bad change of quality of oil;
The existence of colloid makes some vegetable oil dewaxing and winterization become very difficult, and it hinders the crystallization of solid wax at low temperatures and increases the loss of grease;
In sum, our importance of coming unstuck as can be seen; The method of coming unstuck is a lot, generally adopts hydration degum and acid degumming in the oil technology, also has dry type to come unstuck except that above-mentioned two kinds of Degumming methods, wet type is come unstuck, super come unstuck etc.;
Phosphatide in the vegetable oil is very complicated, wants to reach the standard of vegetable oils physical refining, promptly requires phosphorus content in the degummed oil below 15ppm, is not to be a nothing the matter;
The factor that influence is come unstuck is a lot, and the processing technology of crude oil itself has much relations; In the high-quality oil plant, can not can increase by aquation phosphine fat content, but before leaching period of storage long also can impel hydrated phospholipid partly to be transformed into because of the effect of enzyme can not hydrated phospholipid, and we press soya-bean oil and leach the comparison that soya-bean oil comes unstuck and tests machine, the discovery machine presses soya-bean oil and is better than leaching soya-bean oil, and the edible vegetable oil that does not come unstuck can produce bigger harm to health, colloidal impurity can have stronger inhibitory action to metabolism, the edible for a long time back of people produces senile dementia, the danger that action ossifys.
According to the aflatoxins that is contained in the colloid in the modern medicine proof peanut oil also is the inducement of cancer, therefore reduce colloidal substance, reduce aflatoxins, be the master operation in the production process of vegetable oil, and the soda acid of traditional hydration degum come unstuck all exist come unstuck thoroughly, problems such as cost is big, contaminated environment.
In order to overcome the above problems, people are constantly exploring and are studying.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, thereby provide that a kind of technological process is terse, production cost is low, degumming effect is good, can improve the edible oil degumming method of oil quality.
For achieving the above object, the invention provides a kind of edible oil degumming method, this method may further comprise the steps:
Step 1, the crude oil that will just squeeze out are heated to 90 ℃--and 110 ℃;
Add diatomite in step 2, the crude oil after above-mentioned heating, fully stir, mix, filter again, get filter oil;
Step 3, described filter oil is carried out electric separating treatment, obtain having the oil of floccule;
Step 4, the oil that has floccule is carried out centrifugal treating, removes floccule, degummed oil.
Based on above-mentioned, in step 1, the crude oil of just having squeezed out is heated to 95 ℃--105 ℃.
Based on above-mentioned, in step 2, described diatomaceous addition is 0.5%-1.5% of a crude oil weight.
The relative prior art of the present invention has outstanding substantive distinguishing features and obvious improvement, specifically, this method can be removed colloid, makes the phosphorus content in the grease reduce to 12ppm, and can replace traditional hydration degum and acid degumming, save and consume 20%, promote the pass speed of giving birth to, reduce to give birth to and close cost 40%, simultaneously, reduce refining wastewater 15%, preserve the ecological environment; The relative prior art of this edible oil degumming method has that technological process is terse, production cost is low, energy-saving and emission-reduction, pollution-free, degumming effect good, can improve the advantage of oil quality.
The specific embodiment
Now in conjunction with the specific embodiment, the present invention is further illustrated:
A kind of edible oil degumming method, this method may further comprise the steps:
Step 1, the crude oil that will just squeeze out are heated to 95 ℃--and 105 ℃, preferred 100 ℃;
Step 2, adopt gear pump to pump into blending tank the crude oil after the above-mentioned heating, in blending tank, add diatomite, fully stir, mix, filter with the plate and frame filter again, must filter oil; Wherein, diatomite is used for removing the solid impurity of grease;
Step 3, adopt gear pump to pump into glue kettle described filter oil, and described filter oil is carried out electric separating treatment, obtain having the oil of floccule with high-frequency pulse voltage equipment; The high pressure that produces with high-frequency pulse voltage carries out electricity with colloidal impurity in the described filter oil and grease to be separated, and then produces floccule in the grease, and described floccule is exactly the colloidal impurity that leaves with oil content;
Step 4, the described oil that has floccule is carried out centrifugal treating, removes floccule with high speed centrifugation equipment, degummed oil.
Based on above-mentioned, in step 2, described diatomaceous addition is 0.5%-1.5% of a crude oil weight, preferred 1%.
Should be noted that at last: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present invention; And not breaking away from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention asks for protection.
