Abstract
According to a production technique provided by the invention, medium-temperature soft water washing is adopted and phosphoric acid or citric acid is added to chelate heavy metal ions in the process, so that possibility of grease oxidation is reduced; to ensure the quality of edible oil, the dewatering and the decoloration procedures are carried out in a vacuum environment; the stability of the grease is ensured by adding a certain amount of citric acid in the deacidification and deodorization procedures, and the grease is high in yield and good in quality because of physical deacidification and deodorization in high vacuum; automatic temperature adjustment is adopted, so that the product quality is ensured; vacuum pipelines are arranged, so that the vacuum environment is ensured; and the oil circulation period is shortened by adopting a continuous or semi-continuous production mode.
Description
Technical field:
The production technology the present invention relates to, is widely used in the various oil product refining procedures of animal edible oils industry.
Background technology:
At present, on market, medium and small grease company adopts intermittent technique at animal oil oil refining procedure great majority; The needed equipment of this technique has: oil refining cauldron, water washing pan, Decolouring pot, odor removing pot etc., and complicated operation, cost is high; Production cycle is long, and can not guarantee the quality of grease.
Summary of the invention:
The related production technique of this project be semicontinuous, continuous, comprise washing, decolouring, depickling, deodorization production line, Decolouring pot, depickling, deodorization are negative-pressure operation, the function of depickling, deodorization integrates; Washing, dehydration, decolouring adopt cold operation a tractor serves several purposes, simplify auxiliary component; Temperature regulates sensitive, reduces steam consumption, shortens oil product loop cycle; Adopt improved processing parameter, thereby make product with suitable fusing point, extremely light local flavor, higher shortening property, become the desirable feedstock of each shortening manufacturer, reached national animal grease primary standard.
Technical solution:
The production technology that this project is related, according to the requirement of refinery practice, all needs to guarantee the color of grease, the oxidation of the minimizing grease of trying one's best in working process; In operation process, warm soft water washing in employing, and add phosphoric acid or citric acid chelating heavy metal ion, reduced the possibility of Oxidation of Fat and Oils; For guaranteeing the quality of edible oil, at dehydration, bleaching process, must guarantee to carry out under the environment in vacuum; Depickling, deodorization procedures add a certain amount of citric acid is guaranteed the stability of grease, and under high vacuum, grease yield is high, quality good for physical deacidification, deodorization; Employing automatic temp regulates, products quality guarantee; Vacuum-lines is set, guarantees vacuum environment; Adopt the continuous or semicontinuous mode of production, shorten oil product loop cycle.
Accompanying drawing explanation:
Figure is technical process schematic diagram of the present invention.
Embodiment:
The operating process of oil refining plant: crude oil pumps into water washing pan 4 or 5 with pump 1, adds phosphoric acid and soft water and comes unstuck and chelating operation.Obviously separated with oil foot when oil, while sinking rapidly, stop stirring, standing certain hour, emits oil foot, and then edible vegetable oil is drawn to bleacher 6.Oil foot is put to oil foot bucket 38 by bottom evacuated tube, when oil foot contains compared with heavy wool, stops the pin of draining the oil, and oil foot is squeezed into oil foot tank by pump 31, and in water washing tank, remaining oil is sneaked into next tank continuation washing chelating.The edible vegetable oil shifting in water washing tank goes bleacher 6 to carry out adsorption bleaching, and vacuum, makes bleacher 6 reach vacuum state and dewaters and decolour through liquid foam trap 7 with water-ring pump 8, during decolouring, by vacuum, sucks the carclazyte in carclazyte tank 9.Bleached oil is delivered to strainer with decolouring pump 32 and is filtered, and then enters decolouring edible vegetable oil and fills with 13.The decolouring sump oil slop oil tank 12 that enters to decolour sucks bleacher 6 again and decolours.Decolouring edible vegetable oil enters deacid-deodoring combined column 16 by boiled oil pump 33 through spinner-type flowmeter 19, oily interchanger 17,18, hotline heater 15 and carries out deacid-deodoring, deacid-deodoring carries out under the residual voltage state of 3-5 torr, during this period, add quantitative citric acid, guarantee the stability of grease.After deacid-deodoring completes, deodorised oil is through canned-motor pump 34, oily interchanger 17,18, then enters in deodorised oil finished pot 27 through deodorised oil water cooler 25,26.The vacuum of deacid-deodoring combined column is obtained by vacuum system 30, and thermal oil is provided by heat-conducting oil furnace 29.Lipid acid in production process is caught by lipid acid trap 20, through the temporary tank 21 of lipid acid, lipid acid recycle pump 35, lipid acid condenser 23, recycles, and unnecessary entering in bucket reclaimed.
Claims (4)
1. crude oil pumps into water washing pan 4 or 5 with pump 1, adds phosphoric acid and soft water and comes unstuck and chelating.
2. the edible vegetable oil in water washing tank goes bleacher 6 to carry out vacuum suck decolouring.
3. bleached oil enters deacid-deodoring combined column 16 and carries out high vacuum deacid-deodoring through the oily interchanger 17,18 of oil, hotline heater 15; Deodorization procedures adds quantitative citric acid, guarantees the stability of grease.
4. the lipid acid in production process is caught by lipid acid trap 20, through the temporary tank 21 of lipid acid, lipid acid recycle pump 35, lipid acid condenser 23, recycles, and unnecessary entering in bucket reclaimed.
