Abstract
Present invention mainly discloses a kind of refining vegetable oil and its method, specific production method includes filtering, degumming (aquation), depickling (alkalization), hydrogenation, decoloration, the deodorization of crude oil；Refining vegetable oil of the present invention, in the case where ensureing oil quality, except the impurity and pigment in degreasing, the original fragrance of grease and nutrient are not destroyed, and compound country-level vegetable oil refines standard, and oil quality is good.
Description
First, technical field：
The present invention relates to a kind of greases to refine field, more particularly to a kind of refining vegetable oil and its method.
2nd, background technology：
Vegetable oil contains a certain amount of impurity, such as phosphatide, aliphatic acid, pigment, odorous compound etc., these impurity
It must be removed from oil plant, so as to which vegetable oil be made to meet the directly edible requirement of the mankind.Two are generally used to the refining of vegetable oil
Kind method refining of edible oil ＆ fat, i.e. chemical refining and physical refining.In chemical refining, alkali is first generally used again with water process
Processing, so as to remove the gel of oil plant and free fatty.Alkali reacts generation fatty acid salt with free fatty, is total in You Heshui
The fatty acid salt generated under conditions of depositing forms a large amount of emulsion, and neutral oil plant is absorbed in emulsion, so as to cause
Serious oil loss.Especially for the oil plant containing high free acid, such as rice bran oil, emulsification treatment can cause more serious
Refining losses.At present, existing vegetable oil fine smelting method is added mostly using chemical method in the vegetable crude oil first after producing
Enter acid, make phosphatide, albumen, candy isocolloid impurity and acid chemically react, then addition water form cotton-shaped compound, using from
Scheming is centrifuged, and cotton-shaped compound and grease are detached, so as to obtain degumming oil product, degummed oil finally is carried out vacuum
It is dry, moisture removal is removed, obtains refining vegetable oil.Chemical method refining vegetable oil can cause grease certain pollution, after eating
It is not conducive to good health, and chemical refining method be easy to cause environmental pollution, is unfavorable for environmental protection.Comparatively, physical refining
Method is more feasible, which includes degumming step, wherein being gone in a manner that deodorizing process is combined using stripping
Except free fatty acids.Therefore, physical refining method reduces oil loss, removes free fatty acids using distillation mode, improves
Oil plant quality.For the higher vegetable oil of free fatty acid content, physical refining is more attractive.However, Applied Physics refines
Practical experience explanation, only when oily raw material have better quality when, the method could obtain satisfactory effect.
3rd, invention content：
The purpose of the present invention is to overcome the deficiencies of the prior art, provides a kind of refining vegetable oil and its method, we
Under the premise of the refining vegetable oil of method remains the original fragrance of grease and nutritional ingredient, vitamin loss is less, and aliphatic acid contains
It measures low, solves the problems of the prior art.
To achieve the above object, the present invention provides following technical solution：A kind of refining vegetable oil and its method, including crude oil
Filtering, degumming (aquation), depickling (alkalization), hydrogenation, decoloration, deodorization；
Specific make step is as follows:

It is spare after centrifugal filtration.
(2) degumming
70-75 DEG C will be warming up to by process (1) vegetable crude oil, concentration is added according to the content of feedstock oil non-hydratable phospholipid
For 50% citric acid, 25-40min is reacted in souring tank, the lye of 3-4 Baume degrees is added to flocculate, while add oil weight 3.0-
3.5% hot soft water, reacts 46-60min in hydration tank, is warming up to 85 DEG C and centrifuges oil foot and a degummed oil, dry
Degummed oil removing moisture and residual molten；Degummed vegetable oil is warming up to 75 DEG C through heat exchanger, refuels weight 0.02-0.04%'s
A concentration of 75% phosphoric acid carries out 15-30min degumming reactions, obtains secondary degumming oil.
(3) depickling
Degummed oil in (2) is put into cylindrical iron pan, then add 0.02%~0.5% phosphoric acid in cylindrical iron pan
In, it is handled 15-30 minutes at 60~90 DEG C, then sodium hydroxide (caustic soda) warp of 8%~12% concentration of volume read-out 1%~3%
The saponification of 10~30 minutes sinks to the bottom of a pan due to saponified than great, and soap stock is known as after releasing；Then water or dilute is used at 65 DEG C
Acid elution 2 times puts aqueous, then heating removes moisture at 114 DEG C, obtains neutralizing oil after dry.
(4) it hydrogenates
Neutralization oil in (3) is put into snakelike hydrogenation pot, keeps 200 DEG C of kettle temperature, the situation that 41.37 kPas of pressure
The lower nickel formate or nickelous carbonate for adding in grease 0.01%~0.2%, fully reaction obtain hydrogenated oil and fat in 4-6 hours or so.
(5) it decolourizes
Grease after hydrogenation in (4) is put into reaction kettle, it is 225 DEG C of gas, 0.065- to ensure the temperature in reaction kettle
In the environment of 0.13KPa, after being reacted 30 minutes after the activated alumina of addition oil quantity 4%-6% or sulfurous acid decolorising agent, take
Grease is cooled down after going out decoloration, and decolorising agent is separated by filtration after being cooled to 70 DEG C.
(6) it is deodorized
Grease after decoloration in (5) is put into 270 DEG C of temperature, in the vacuum tank of air pressure 5.07KPa, is put into appropriate activity
Charcoal is distilled, and is added in after the grease cooling in vacuum tank i.e. available after 0.005%~0.01% citric acid of oil mass
Refining vegetable oil.
