Abstract
The invention provides a production method of soybean crude oil. The production method comprises steps of magnetic screening, screening, softening, drying, grinding, germ flattening, puffing, leaching, primary evaporating, secondary evaporating, and steam stripping. The provided production method is more scientific, can effectively improve the quality of soybean crude oil, maintains the beneficial components in soybeans, and prevents the generation of harmful substances.
Description
Technical field
The invention belongs to soybean oil production technique field, in particular, the present invention relates to a kind of production method of crude oil of soybean.
Background technology
Soybean oil is from soybean, squeeze the one oil extracted, usually we are referred to as " soybean salad oil ", are one of the most frequently used cooking oils, and the traditional fabrication of crude oil of soybean adopts milling process, its technical process comprises material picking, heat, rolls embryo, squeezing, filter, the shortcoming of prior art has: in order to eliminate beany flavor in product and other peculiar smell, increase oil yield, first by soybean through heat denatured process.High-temperature heating treatment, not only make the heat loss such as the unsaturated fatty acids in soybean, VE, and make that the crude oil color of squeezing out is dark, impurity is many and the healthy material of the harm such as propylene chlorohydrin precursor, trans fatty acid may be produced, and additionally add the problems such as oxidation inhibitor.。
Summary of the invention
The present invention is that shortcoming in order to overcome above-mentioned prior art proposes, and its technical problem solved is to provide a kind of more science, effectively can improve the quality of crude oil of soybean, retain beneficiating ingredient in crude oil, prevent the production method that objectionable impurities produces.
For this reason, the invention provides a kind of production method of crude oil of soybean, specifically comprise the following steps:
(1) pre-treatment is carried out to raw soybeans, namely remove the magnetic impurity in raw soybeans by magnetic separation, then by the large and small impurity in rotary flat sieve removing soybean and light impurity;
(2) make sofening treatment by above-mentioned through pretreated soybean, utilize the moisture content of quality-adjusting device adjustment soybean at a slow speed;
(3) the dry above-mentioned soybean through sofening treatment is to increase the plasticity-of soybean;
(4) soybean after dried is carried out break process;
(5) embryo process is rolled to the large bean cotyledon of fragmentation, form thin and uniform blank;
(6) embryo sheet is put into bulking machine and carry out puffing;
(7) embryo sheet is put into flat-turn leacher, with 6# solvent for solvent, the soybean miscella in embryo sheet is leached;
(8) evaporation process is done to the soybean miscella of above-mentioned leaching, and carry out twice evaporation, namely according to difference (9) the boiling point evaporative removal impurity at twice of mixing well cuts;
(10) mixing oil through evaporation process is positioned over stripping tower, thoroughly removes residual solvent by stripping, obtain green soy bean oil.
Further, adopt aperture to be the rotary flat sieve of 8 orders/inch and 3 in step 1, the thickness of embryo sheet is 0.3 below ㎜.
Further, in step 7, wherein extraction time is at 80min ~ 100min, and temperature is 55 DEG C, pressure-0.01 ~-0.02mmH.
Further, in step 10, stripping carries out under the negative pressure of-0.03 ~ 0.04INHg.
The invention has the beneficial effects as follows: provide a kind of more science, effectively can improve the quality of crude oil of soybean, retain beneficiating ingredient in crude oil, the production method of the crude oil of soybean preventing objectionable impurities from producing.
Embodiment
Below in conjunction with embodiment, the present invention is further described.
Magnet is utilized by soy material to remove magnetic impurity in raw material;
Utilize soybean and impurity in the difference of granular size and weight, by the relative movement at compass screen surface of soybean and impurity, with aperture be 8 orders/inch and 3 rotary flat sieve remove large and small impurity in the soybean after magnetic separation and light impurity;
Utilize quality-adjusting device at a slow speed to adjust the moisture content of pretreated soybean, ensure the technological effect that soybean is leached;
Utilize flash dryer to carry out rapid drying to the soybean after softening, the plasticity-of soybean is increased, is convenient to next step process operations;
With crusher, dried cracking soybeans is become 2-4 lobe beans, make it have certain granularity and meet the condition of rolling embryo, require the oil plant epigranular after fragmentation, not fuel-displaced, not agglomerating, become powder less;
Adopt and single to large bean cotyledon, embryo is rolled to rolling flaker, roll into thin and uniform blank.Require that blank fines content is little, oil-proof, thickness is 0.3 below ㎜;
Embryo sheet is squeezed in extruder cylinder barrel, heat, shear, the effect such as to rub, and oil plant cell is entirely destroyed, and in cell, grease fully exposes, in the template exit of oil plant extruder, sudden pressure reduction, water vapor evaporates, thus obtains the expanded material of appropriateness;
Employing flat-turn leacher leaches, and with 6# solvent for solvent, the time of leaching, temperature was 55 DEG C at 80min ~ 100min, and the oil immersion of soybean goes out by pressure-0.01 ~-0.02mmH;
Be made up of solvent, grease and the lipoid with grease from the mixing oil of leacher extraction, utilize the boiling point difference of grease and solvent, heating is carried out to mixing oil and makes it reach boiling temperature, thus solvent gasification is separated with grease.Mixing oil first makes concentration reach 60% ~ 70% through the first vaporizer;
Mixture after single vaporization makes concentration be increased to 90% ~ 95% by the second evaporator evaporation again;
Mixing oil after vaporized is put into stripping tower, is thoroughly cleared out by the residual solvent in mixing oil by stripping tower, the stripping of mixing oil carries out under negative pressure (-0.03 ~ 0.04INHg), obtains crude oil of soybean.
