Abstract
A process for refining peanut oil to make it have strong fragrance includes peeling, wetting, steaming, parching, high-pressure extruding, pressure filtering, low-temp hydrating and filtering. Its heating medium is YD-type thermal conducting oil. Said process features low cost and high output rate up to 43%.
Description
The present invention relates to the process for refining of Vegetable oil lipoprotein.
The process for refining of traditional peanut oil as the interim introduction of 5-6 in 93 years of " oil technology " magazine, all needs to mix the toast earthnut rice more than 20%, adopts forced cooling, is equipped with extract technology etc., and complex process is strict.The patent No. is 90106324, X " hydration coldfiltering and degumming technology by continuous ejection of vegetable oil ", need to use industrial filter paper filtering, continuous sprayer is made complicated, heating medium need be used steam, and heat-energy losses is big, and power consumption is high, therefore, this technology is the production cost height not only, and the processed oil yield is low, the highlyest can only reach 33%.
The objective of the invention is to propose the heavy fragrant peanut oil process for refining that a kind of technology is simple, production cost is low, the processed oil yield is high.
This heavy fragrant peanut oil process for refining comprises the steps successively.
A, the Semen arachidis hypogaeae of screening after the impurity elimination rolled embryo, pressure rolling becomes the embryo sheet of 2-5mm or the lobe grain of 4-10 lobe/grain, makes stock;
B, spray into an amount of water in stock, making the water content of stock is 15-17%, makes wet embryo;
C, with heating medium wet embryo is steamed afterwards earlier and to fry, it is that 127 °-130 ℃, water content are 1-2% that the steaming stir-fry time is controlled at the temperature that makes the stir-fry embryo;
D, squeeze frying embryo, coarse wool oil and oil cake;
E, with coarse wool oil scarfing cinder impurity elimination, filtering under pressure, crude oil and oil cake;
F, the 1-3%, the concentration that add crude oil weight in crude oil are the sodium chloride solution of 4-6%, are with crude oil aquation 20-30 minute in temperature under 70 °-90 ℃ the condition;
G, the crude oil after the aquation is cooled to 50 °-60 ℃ after, dross is filtered, the elaboration oil and the oil cake that must come unstuck;
H, elaboration oil is insured filtration again, make processed oil;
I, the oil cake that obtains among d, e, the g is incorporated into fries in the embryo, proceed squeezing.
Wet embryo is steamed afterwards earlier with heating medium described in the above-mentioned technology fried, and is to select for use to pass through the nontoxic thermal oil of YD type that heats up, and with the mode of closed circulation cooking pot heated.Press ratio in the squeezing step is 1: 30-35.The scarfing cinder impurity elimination comprises that via hole diameter is that the sieve plate of 0.8mm is removed big slag, removes little slag through 40-50 purpose screen cloth again, tells thin slag through precipitation again.
The peanut stock is carried out the high-moisture steaming in the present invention and high-temperature is fried, big compression ratio pressure is got coarse wool oil, and through scarfing cinder impurity elimination operation, make crude oil, and then provide the crude oil aquation, the prerequisite of coming unstuck, after making the phosphatide water-swelling in the crude oil, with the assorted subparticle conglomerate of glue, through cooling, increase the viscosity of crude oil again, quicken the gathering of the phosphatide of assorted subparticle of glue and water-swelling and separate out, after filtration, remove the precipitate of the overwhelming majority, at this moment, the remaining micro-dregs of fat are as coming unstuck skeleton in the crude oil, continue to come unstuck, the phosphatide and the assorted subparticle continuation of the glue conglomerate of water-swelling are separated out, again through filtering under pressure, dross is filtered and insurance is filtered, and makes processed oil.Heating medium adopts YD type thermal oil, heats with the closed circulation mode.Because of this thermal oil heat absorption, exothermal efficiency height, the maximum operation (service) temperature height, and nontoxic, tasteless, harmless.Therefore, the present invention has following characteristics:
1, do not need to mix toast earthnut rice more than 20%, saved forced cooling and extract technology, thereby exempted corresponding apparatus, the technical process of having broken of contracting has reduced equipment cost;
2, compare with the steam medium heating, reduce thermosteresis 7-8 doubly, reduced fuel consumption and power consumption, 70-80% reduces production costs;
3, the yield of processed oil improves 10%, and oil yield can reach 43%;
4, improved the giving off a strong fragrance flavor of peanut oil;
