Abstract
The present invention relates to the purification techniques field of Vegetable oil lipoprotein, it comprises the crude oil impurity elimination, spray into that crude oil after water vapor and the impurity elimination sharply mixes, aquation, cooling, press filtration again, the present invention not only just can be to vegetable oil degumming without organic acid, acid anhydrides degumming agent, and the processed oil yield that can will come unstuck brings up to 99%.
Description
The present invention relates to the purification techniques field of Vegetable oil lipoprotein.
The degumming technology of vegetables oil such as publication number are EP269277A
2" degumming technology of triglyceride " be under less than 40 ℃ temperature, in crude oil, add organic acid and acid anhydrides, in crude oil, add synthermal water subsequently, the grain slag that contains rubber cement in the crude oil is separated, phospholipids content is reduced greatly, and bleaching again behind the degumming of oil is made processed oil; The patent No. be US3221801's " vegetables oil come unstuck continuously and Yelkin TTS forms novel process " be that the vegetables oil that will be come unstuck enters heat exchanger continuously by supply line, in heat exchanger, temperature is elevated to the temperature that is suitable for coming unstuck, the oil that is heated up is sent into the high temperature separate pump through pipeline, come unstuck in the high temperature separate pump, the vegetables oil after coming unstuck is made degummed oil through spraying water extracter again.Above-mentioned two kinds of degumming technologys all need to add organic acid, acid anhydrides degumming agent, have increased the cost that comes unstuck; The processed oil yield of coming unstuck is low, can only reach 95%.
The objective of the invention is to propose a kind ofly not only just can bring up to 99% novel process to vegetable oil degumming but also the processed oil yield that can will come unstuck without organic acid, acid anhydrides degumming agent.
This technology is:
A is that 80 ℃-85 ℃ machine presses crude oil scarfing cinder impurity elimination, makes dregginess in the crude oil account for the 1-2% of crude oil weight to temperature, or temperature is 80 ℃-85 ℃ leaching crude oil deodorization impurity elimination, makes extraction solvent oil-contg in the crude oil less than 50ppm;
B is with 0.5-4.5/cm
2When pressure sprays into water vapour in the mixing tank, machine after above-mentioned impurity elimination press for extracting juice crude oil or leaching crude oil are sucked and be pressed in the same mixing tank, crude oil is sharply mixed with water vapour, formation temperature is the mixing oil that 80 ℃-90 ℃, crude oil begin aquation, the weight in wet base in the mixing oil be contain phosphatide weight in the crude oil 2-5 doubly;
The above-mentioned mixing oil of c sprays into hydrator continuously, and at the hydrator internal rotation, continues aquation 3-5 minute;
Mixing oil after the d aquation is cooled to 55 ℃-60 ℃ through water cooler continuously;
The cooled mixing oil of e continuously through pressure filter with 1.5-5.0kg/cm
2Filter pressure be separated into processed oil and the oil cake that comes unstuck;
F mixes oil cake and steam to fry in the embryo that crude oil is got in further squeezing or crude oil is got in leaching.
Because the present invention sprays into mixing tank with the water vapour of certain pressure, in mixing tank, acutely mix with the crude oil short period of time, carry out heat exchange simultaneously: water vapour is on the one hand with the heat transferred crude oil, make the crude oil temperature be elevated to suitable 80 ℃-90 ℃ of coming unstuck, condense into water on the other hand, create the prerequisite of crude oil aquation, this moment, the micro-dregs of fat in the crude oil are as the skeleton that comes unstuck, the assorted subparticle of glue is assembled, phosphatide water-swelling and most of cohesion are separated out, after the mixed mixing oil of crude oil and water sprays into hydrator by mixing tank, continue rotation, aquation, the abundant water-swelling of phosphatide, the assorted subparticle suction of glue is agglomerating, suitably reduce through the temperature of water cooler again, increase and mix oil viscosity, impel the assorted further conglomeration of subparticle of glue to separate out mixing oil, so far, the process of coming unstuck is finished, and is separated into processed oil and oil cake through pressure filter again, and oil cake is incorporated into to steam to fry in the embryo and continues to get oil.Therefore, have following characteristics:
1, saves organic acid, acid anhydrides degumming agent, reduced production cost;
2, the processed oil yield height that comes unstuck can reach more than 99%;
3, do not need high temperature separate pump, sprinkling water extracter, facility investment is few, and power is power-saving;
Thus, the factory of 15000 tons of vegetables oil that come unstuck of an annual output can obtain the economic benefit of ten thousand circles surplus in the of 100 every year more.
The embodiments of the invention accompanying drawings, in the accompanying drawing, Fig. 1 realizes process flow sheet of the present invention, Fig. 2 is the structure and the annexation figure of mixing tank and hydrator.
The degumming technology of example 1 peanut oil
From oil press zhai (1) expressed temperature is that to press the crude oil via hole diameter be that the sieve plate (2) of 0.8mm is removed big slag for 80 ℃-85 ℃ machine, rotating screen through 48 eye mesh screens are housed (3) is removed medium and small slag again, tell tiny slag through setting tank (4) again, make dregginess in the crude oil account for the 1-2% of crude oil weight, or to temperature be 80 ℃-85 ℃ leaching crude oil through deodorizing tank (15) deodorization impurity elimination, make extraction solvent content in the crude oil less than 50ppm; Machine in the setting tank (4) is pressed crude oil to Open valve (5) or Open valve (16) is precipitated the leaching crude oil in the deodorizing tank (15) by pump (6) suction gravitation tank (7), when spraying into water vapour in the mixing tank (9), Open valve (8), crude oil in the gravitation tank (7) is sucked continuously and is pressed in the same mixing tank (9), and water vapour pressure is 0.5-1.0kg/cm
2, crude oil is sharply mixed with water vapour, formation temperature is 80 ℃-90 ℃ a mixing oil, because phospholipids content is 0.5-1.0% in the crude peanut oil, is 1.0-5.0% so contain the weight that is condensed into water by water vapour cooling in the mixing oil; Directly spray into hydrator (10) from the mixing oil of mixing tank (9) ejection, at hydrator (10) internal rotation, aquation 4-5 minute; It is in the pipeline of water cooler (12) of heat-eliminating medium that mixing oil after the aquation is passed with water by pump (11) suction, makes the mixing oil temperature reduce to 55 ℃-60 ℃; Cooled mixing oil with 10 * 10 white canvas through chamber-type press filter (13) with 1.5-5.0kg/cm
2Filter pressure is separated into come unstuck processed oil and oil cake; Processed oil enters absolute oil jar (14), and oil cake mixes steam to fry in the embryo that crude oil is got in further squeezing or crude oil is got in leaching.The quality of the processed oil after coming unstuck sees Table one, and the processed oil yield reaches more than 99.6%.
