Description
Technical field
The present invention relates to a kind of food oils leaching oil extracting process, specifically, related to the leaching oil extracting process for waste carclazyte behind a kind of decolouration in edible lipid industry.
Background technology
According to the pertinent data record, the oil and fat refining ability that China is annual has at present reached annual 2400 ten thousand tons.In refining process, need to adopt carclazyte processings of decolouring, the carclazyte addition calculating by 3%, carclazyte year total flow can reach 720,000 tons; By certificate of analysis, useless carclazyte contains Residual oil can reach 33%, so, and should oil-containing 72 * 33%=23.76 in 720,000 tons of useless carclazytes ten thousand tons.At present the useless carclazyte in the whole nation substantially all is in the no state of abandoning, and has both polluted environment, has wasted resource again, and the present edible oil 2/3 of China is by import, and feedstuff industry, chemical industry also exist bigger breach with oil; Although at present domestic have part individual economy adopting the useless carclazyte of method processing of frying squeezing with steaming, its technology falls behind, and the useless carclazyte Residual oil content after the squeezing is still about 12%, benefit is not obvious, and the amount of can not form, it is too much that the useless carclazyte after the processing contains Residual oil, still lacks recycling property.
At present, traditional leaching oil extracting process and equipment mainly are divided into two kinds of pot group type and hoirzontally rotatings, it mainly is that employing 5# or 6# solvent oil are that carrier refines, solvent composition is ethane or butane, promptly mainly utilize the strong perviousness and the volatility of solvent, oil plant remaining in the oil cake behind the frying oil is taken out of, then mixed solution is pumped into vaporizer, just the solvent evaporation in the mixed solution is come out by 1st effective evaporator, the gaseous solvent that goes out to be evaporated enters condenser, be condensed into liquid solvent and enter solvent tank, the one leaching oil of imitating after the evaporation pumps into 2nd effect evaporator again, continues evaporation, and the solvent that evaporates is still by being recovered to solvent tank after the condenser condenses, residual molten dropping to about 200PPM in leaching oil promptly obtains qualified leaching crude oil.
Traditional leaching oil extracting process at the leaching material mainly be grouts or oil cake after the oilseed plant squeezing, also do not have both at home and abroad at present and carry oil tech for the leaching of the useless carclazyte of non-plant oil-containing material.
According to understanding, once there was producer to adopt the oily waste water carclazyte was mixed the trial that mixing is leached in the plant oil cake, but leaching the back finds, because of the carclazyte particle is about 200 orders, its particle is meticulous, carclazyte is under solvent action, there is quite a few to be dispersed in solvent and the mixing oil with trip ionic state, stop up filter screen and condenser easily, need to pay very big labor capacity and will clear up, moreover carclazyte is inorganic mineral substance, carclazyte in process of production, to use the mineral acid sulfuric acid acidation, though removed most of sulfuric acid by washing in the operation, also had the sulfuric acid of trace to be present in the carclazyte, therefore, mix the plant cake of carclazyte or oil cake after oil is carried in leaching, post-processed exists great problem.
In sum, decolouring back oily waste water carclazyte, has feasibility by the oil that uses the traditional technology method to extract in the carclazyte, but the problem that solves is: should guarantee carrying out smoothly of leaching oil extracting process process, the carclazyte powdered granule does not incorporate in the mixing oil with the free state in the time of guaranteeing to leach again; This just need be the carclazyte of preparing to leach by the natural sedimentation method rapid precipitation, and then, the mixed solvent oil that extracts above the throw out enters vaporizer, circulating and evaporating.
In order to overcome the above problems, people are seeking a kind of ideal technical solution always.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, thus provide a kind of technical process simple and practical, leach the leaching oil extracting process for waste carclazyte carry behind the good decolouration in edible lipid industry of oily efficient height, gained quality of crude oil.
To achieve these goals, the invention provides the leaching oil extracting process for waste carclazyte behind a kind of decolouration in edible lipid industry, may further comprise the steps:
Step 1, get the raw materials ready: be on the waiting list useless carclazyte, ceramic earth, terra alba, calcium powder four sample raw materials, by weight percentage, wherein, described useless carclazyte accounts for 82%～94% of four sample raw material weight sums, described ceramic earth accounts for 1.5%～4.5% of four sample raw material weight sums, described terra alba accounts for 2%～8% of four sample raw material weight sums, and described calcium powder accounts for 2%～6% of four sample raw material weight sums;
Be on the waiting list solvent oil according to 1.8～2.4 times of aforementioned four sample raw material weight sums;
Step 2, stirring: pour the described ceramic earth of step 1, described terra alba and described calcium powder in the stirrer fully stirring by aforementioned ratio, churning time is 2～8 minutes;
Step 3, restir: pour described solvent oil of step 1 and described useless carclazyte in the described stirrer fully stirring by aforementioned ratio again, churning time is 10～30 minutes, gets compound;
Step 4, precipitation: described compound is carried out natural sedimentation, and sedimentation time is 50～80 minutes, and is last, gets throw out and the mixing oil that floats on above the throw out;
Step 5, circulating and evaporating: the mixing oil of drawing above the throw out enters vaporizer, carries out circulating and evaporating, until obtaining qualified crude.
Based on above-mentioned, in step 1, described useless carclazyte accounts for 88% of four sample raw material weight sums, and described ceramic earth accounts for 3% of four sample raw material weight sums, and described terra alba accounts for 5% of four sample raw material weight sums, and described calcium powder accounts for 4% of four sample raw material weight sums.
Based on above-mentioned, the grain diameter of described useless carclazyte, described ceramic earth, described terra alba, described calcium powder is 160 orders～220 orders.
Based on above-mentioned, in step 5, the temperature of described circulating and evaporating is controlled at below 100 ℃.
We are through repeatedly test, proved the feasibility of this technology, and evidence: the interpolation of ceramic earth, terra alba and the calcium powder of ratio of the present invention is only adding proportion, through useless carclazyte residual oil content≤2% that leaches, if exceed ratio of the present invention, can cause sedimentation time long, the oil quality of leaching is starkly lower than the quality of ratio of the present invention, is unfavorable for that also the grease scale leaches; Simultaneously, residual oil content 〉=8% of useless carclazyte is unfavorable for leaching the best leaching effect of carrying oil.
In addition by evidence in many ways: in the carclazyte precipitation process, mixing an amount of ceramic earth, terra alba and calcium powder can accelerate precipitation; The experiment contrast shows: the sedimentation time that adds ceramic earth, terra alba and calcium powder is 1/3rd of the natural sedimentation time, just save for 2/3rds time than natural sedimentation, so more help a large amount of and scale production, in addition, ceramic earth can also absorb a part of colloid that leaches the crude oil the inside.
The relative prior art of the present invention has outstanding substantive distinguishing features and obvious improvement, and specifically, this leaching oil extracting process is increased to more than 95% the product yield, guarantees oil quality to greatest extent, realizes continuous mass industrialized production; This technology investment is little, benefit is big, belong to again produce, the new technology of capable of circulation, innovation, environmental protection.
