Abstract
The invention discloses an alkali refining washing process for cottonseed oil. The processing steps include (1) crude oil filtering, (2) alkali refining, (3) washing and (4) drying, wherein the crude oil filtering includes removing impurities of cake dregs, cotton pulp scraps, silts and the like, the alkali refining includes adding an alkaline liquor with a concentration of 17% to 20% in the crude oil to fully mix, heating to 85 DEG C to 90 DEG C to perform a centrifugal separation and removing soapstock, the washing includes controlling the oil temperature at 75 DEG C to 80 DEG C, adding a saline solution which has an oil weight of 10%, a temperature between 90 DEG C and 95 DEG C and a concentration of 2% to 4% and is obtained from the step (2), uniformly mixing and stirring for one hour, precipitating for 8 hours and discharging waste water, and the drying includes heating the oil to 130 DEG C to 140 DEG C, vacuumizing for 6 to 8 hours and removing moisture in the oil to obtain a refined oil product. The alkali refining washing process for the cottonseed oil has the advantages that the process is simple, the operation is convenient, cottonseed oil quality and oil yield can be improved, the refined oil product color and luster are reduced, the brightness is increased, the saponified matter content is decreased, and the transparency of the refined oil product is improved.
Description
Technical field
The present invention relates to the alkali refining washing process of oil plant manufacture field, particularly Oleum Gossypii semen.
Background technology
At present, cotton is one of China's main economic crops, and output occupies first place in the world, and cottonseed is the seed of cotton, whole seed oil-containing 10-15%, and oil-containing 20-30% in the cotton benevolence is one of the world's nine big oil rice.And mostly the cotton oil refining is alkali-refining process, and this technology: ⑴, crude oil filter: remove impurity such as cake slag, cotton dregs chip, silt; ⑵, in crude oil, add the alkali lye of 18%-20%, stir 0.5h, be heated to 60 ℃, carry out the 3h precipitate and separate, remove soap stock; ⑶, drying: oil is heated to 130 ℃-140 ℃, carries out vacuum 4h, remove water content in oil, obtain processed oil.In this process,,, can cause a large amount of neutral oil saponification, influence the processed oil yield if react for a long time because temperature of reaction is too high; And the reaction of short period of time, the soap that then generates does not have time enough absorption gossypol, and gossypol can not be broken away from fully, causes the Oleum Gossypii semen color to be difficult to remove.
Summary of the invention
The object of the invention is for overcoming above-mentioned weak point, and provides a kind of, can improve Oleum Gossypii semen quality and oily yield, reduces finished product oil colours pool, increases brightness, reduces saponified matter content, the alkali refining washing process of the Oleum Gossypii semen of enhancing the transparency.
The technical scheme that the present invention adopted: the alkali refining washing process of Oleum Gossypii semen, the procedure of processing of this technology: ⑴, crude oil filter: remove impurity such as cake slag, cotton dregs chip, silt; ⑵, alkali refining: the alkali lye that in crude oil, adds 17%-20% concentration carries out thorough mixing, is heated to 85 ℃-90 ℃ and carries out spinning, removes soap stock; ⑶, washing: at 75 ℃-80 ℃, adding the resultant oil of step ⑵, to weigh 10% temperature be that 90 ℃ of-95 ℃ of concentration are the salt solution of 2%-4%, mixes and stir 1h with oily temperature control, and deposition 8h emits waste water; ⑷ dry: oil is heated to 130 ℃-140 ℃, carries out vacuum 6-8h, remove water content in oil, obtain processed oil.
As a kind of improvement project of the present invention be: the concentration of lye the best in the said ⑵ step is 19%.
As another kind of improvement project of the present invention be: the salt solution optimum concn is 2.5% in the said ⑶ step.
As another kind of improvement project of the present invention be:: oily temperature the best is 140 ℃ in the said ⑷ step.
Technology of the present invention is simple, and is easy to operate, can improve Oleum Gossypii semen quality and oily yield, reduces finished product oil colours pool, increases brightness, reduces saponified matter content, improves the transparency of processed oil.
