Abstract
The present invention discloses a rapeseed oil production process, wherein rapeseed is subjected to impurity removing through a cleaning sieve, and then is subjected to a freezing treatment to carry out wall breaking so as to easily achieve oil leaching. According to the present invention, a levigation process is adopted, 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 rapeseed oil production field,, be exactly a kind of rapeseed oil production technique.
Background technology
Rapeseed oil is commonly called as rape oil, is again caraway oil, is with Semen Brassicae campestris, to press the liquid of the transparent or semitransparent shape of gained, one of main edible oil of Ta Shi China, 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 ingredient such as the unsaturated fatty acids such as its contained linolic acid and vitamin-E can be absorbed by body well, has certain vessel softening, the effect delaying senility.Existing rapeseed oil adopts and fries rear squeezing, or adopts organic solvent lixiviate, or adopts the methods such as supercritical extraction, the problem such as all have organic solvent pollution in various degree, oil yield is not high, Toxic is residual.
Summary of the invention
The object of this invention is to provide a kind of gained rapeseed oil high purity, free of contamination rapeseed oil production technique.
Above-mentioned purpose realizes by following scheme:
A production technique for rapeseed oil, is characterized in that: comprise the following steps:
(1), Semen Brassicae campestris is clean clearly, dry to water content 5-8%;
(2), be sent in freezer and refrigerate 16-18 hour, temperature of ice house is-25--20 ℃; After taking-up, be sent in tunnel type drying room and dry, baking room temperature is 50-60 ℃, and the time is 5-6 hour; Repeated multiple times;
(3), Semen Brassicae campestris added to water grind, in water, add the salt of 0.3-0.5%, profit layering, isolates preliminary grinding rapeseed oil;
(4), isolated Semen Brassicae campestris slag, wash with water repeatedly, be incorporated in step (3) defibrination, carry out profit layering;
(5) the Semen Brassicae campestris slag, after washing, dries to water content 15-18% at 50-60 ℃, sneaks into the rapeseed hull 10-20 order meal that is equivalent to Semen Brassicae campestris slag weight 3-5%, enters after entering that oil press zhai is pre-again and squeezing and obtains just squeezing crude oil and seedcake; Just squeezing crude oil can otherwise processed;
(6), preliminary grinding rapeseed oil adds the water that is equivalent to the heavy 20-30% of oil, passes into steam heating to 60-70 ℃, beginning stirring velocity is 100-155r/min, confuses 30-40 minute, quiescent setting 5-6 hour, makes oily water separation, the preliminary grinding rapeseed oil after separation dewaters;
(7), preliminary grinding rapeseed oil in-5--3 ℃ refrigeration 3-5 hour, then, filter impurity elimination;
(8), preliminary grinding rapeseed oil is through decolouring, the discoloring agent that described decolouring is used is diatomite and gac, diatomite and gac part by weight are 2-3:1, the 1%-5% that discoloring agent consumption is oil mass;
The described following processing of diatomite process: diatomite first soaks 2-3 hour with 10-15% hydrochloric acid soln, then, the sodium hydroxide solution of putting into 10-12% soaks 2-3 hour, the hydrogen peroxide solution of putting into again 10-15% soaks 1-2 hour, then deionized water is cleaned, at 10000-12000 rev/min of condition high speed dispersion 10-15 minute;
(9), preliminary grinding rapeseed oil washes with water again, separation, obtains clean preliminary grinding rapeseed oil.
The production technique of described rapeseed oil, is characterized in that:
(1), just squeeze crude oil and add the water that is equivalent to its weight 20-30% to carry out aquation, with 80-90r/min rapid stirring about 30 minutes, after change into 60-70r/min low rate mixing about 10 minutes, after aquation, filtering separation, obtains aquation crude oil;
(2), aquation crude oil passes through decolouring, essence is filtered, and obtains two squeezing rapeseed oils.
Beneficial effect of the present invention is:
(1), the present invention adopts freezing post-heating technique, is conducive to vegetable seed cell wall breaking, improved oil yield, than traditional pressing method, improves oil yield 5-8%;
(2), the present invention adopts watermill process to get oil, without any pollution, guaranteed the pure of oil product, 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;
(4), output preliminary grinding rapeseed oil of the present invention and two squeezes rapeseed oils, all has high-quality grade, can distribution, or mingle blending is sold.
