Abstract
The present invention discloses a rapeseed stir-frying rapeseed oil production process, wherein rapeseed is subjected to impurity removing through a cleaning sieve, then is subjected to a freezing treatment to carry out wall breaking, and is subjected to stir-frying to achieve a 60-70% doneness so as to easily achieve oil leaching. According to the present invention, a levigation process is adopted, ozone is introduced, and decoloration adopts a specially-treated absorbent; processes of freezing and heating are sequentially performed, such that wall breaking of rapeseed cells is easily achieved, and an oil yield of the production process of the present invention is increased, and is increased by 5-8% compared with an oil yield of the conventional pressing method; and the levigation process is adopted to take oil, such that no pollution is generated, oil product purity is ensured, a pure nature characteristic is provided, and green food requirements are met.
Description
Technical field
The present invention relates to the rapeseed oil production field,, exactly be a kind of rapeseed oil production technique.
Background technology
Rapeseed oil is commonly called as rape oil, is again caraway oil, is the liquid that presses the transparent or semitransparent shape of gained with Semen Brassicae campestris, it is one of main edible oil of China, and main product is in the Yangtze valley and the ground such as southwest, northwest, and output occupies first place in the world, human body is very high to the specific absorption of rapeseed oil, can reach 99%.Therefore the nutritive ingredients such as the unsaturated fatty acids such as its contained linolic acid and vitamin-E can be absorbed by body well, have certain vessel softening, the effect that delays senility.Existing rapeseed oil adopts and fries rear squeezing, perhaps adopts the organic solvent lixiviate, perhaps adopts the methods such as supercritical extraction, the problem such as all have in various degree organic solvent pollution, oil yield is not high, Toxic is residual.

(4), the ripe Semen Brassicae campestris of 6-7 added water grind, add the salt of 0.3-0.5% in the water, pass into ozone 20-30 minute, the preliminary grinding rapeseed oil is isolated in the profit layering;
(5), isolated Semen Brassicae campestris slag, wash with water repeatedly, incorporate in step (3) defibrination, carry out the profit layering;
(6), the Semen Brassicae campestris slag after the washing, dry to water content 15-18% under 50-60 ℃, sneak into the rapeseed hull 10-20 order meal that is equivalent to Semen Brassicae campestris slag weight 3-5%, enter and obtain just pressing crude oil and seedcake after entering again that oil press zhai is pre-and pressing; But just press the crude oil otherwise processed;
(7), the preliminary grinding rapeseed oil adds the water be equivalent to the heavy 20-30% of oil, passes into steam heating to 60-70 ℃, the beginning stirring velocity is 100-155r/min, confused 30-40 minute, quiescent setting 5-6 hour, make oily water separation, the preliminary grinding rapeseed oil after the separation dewaters;
(8), the preliminary grinding rapeseed oil is in-5--3 ℃ of refrigeration 3-5 hour, then, filters impurity elimination;
(9), the preliminary grinding rapeseed oil through the decolouring, the discoloring agent that described decolouring is used is diatomite and gac, diatomite and gac part by weight are 2-3:1, the discoloring agent consumption is the 1%-5% of oil mass;
The following processing of described diatomite process: diatomite soaked 2-3 hour with the 10-15% hydrochloric acid soln first, then, the sodium hydroxide solution of putting into 10-12% soaked 2-3 hour, the hydrogen peroxide solution of putting into again 10-15% soaked 1-2 hour, then deionized water was cleaned, 10000-12000 rev/min of condition high speed dispersion 10-15 minute;
(10), the preliminary grinding rapeseed oil washes with water again, separates, and gets clean preliminary grinding rapeseed oil.
2, the production technique of rapeseed oil according to claim 1 is characterized in that:
(1), just press crude oil and add the water be equivalent to its weight 20-30% and carry out aquation, with the 80-90r/min rapid stirring about 30 minutes, after change into the 60-70r/min low rate mixing about 10 minutes, after aquation was complete, filtering separation got the aquation crude oil;
(2), the aquation crude oil is through decolouring, smart filter, obtain two and press rapeseed oils.
Beneficial effect of the present invention is:
(1), the present invention adopts freezing post-heating technique, is conducive to the vegetable seed cell wall breaking, fries to 6-7 ripely, improved oil yield, improves oil yield 5-6% than traditional pressing method;
(2), the present invention adopts watermill process to get oil, without any pollution, guaranteed the pure of oil product, and is pure naturally natural, meets the requirement of green food;
(3), sorbent material of the present invention processes through special pearl, improved absorption venomous injurant ability;
