The chemical solvents extraction process is applicable to too and directly extracts vegetables oil from the Hemp Seed seed meal minces, English Patent GB632304A discloses a kind of method that extracts the continuous-dissolution extraction vegetables oil after improving of vegetables oil, will extract the solid seed of oil after pulverizing.U.S. Pat 6307077B1 then discloses a kind of use machine extraction process vegetables oil has been carried out the purified method.
Chinese patent CN1714661A discloses a kind of high gamma-linolenic acid edible oil and its production and application, and it is to be raw material with the numb seed of Yunnan fire, after the impurity elimination the numb seed of fire is dried; With squeezing machine it is squeezed repeatedly, get crude oil.The numb seed crude oil of above-mentioned fire is decon after filtering; And carry out depickling with thermokalite water, make acid value reach 0.8-1.5%; Add the hot water repetitive scrubbing afterwards, and utilize vacuum hydro-extraction; Refining also adds discoloring agent and decolours.The essential oil of gained shows that after testing gamma-linolenic acid content wherein is 31.07-31.70%.In this patent, being that the numb seed of fire has been carried out repeating squeezing, mainly is because it directly puts into squeezing machine with the numb seed of fire, owing to obtain to contain in the embryo sheet the fiery numb seed shell of a large amount of pulverizing after squeezing, make further squeezing obtain crude oil and become more and more difficult, influence the raising of oil yield.That is to say, in this patent, the embryo sheet that produces in squeezing crude oil process is not handled, content after making embryo sheet mesochite pulverize can be higher, and more lubricant component is also contained in its inside simultaneously, so the grease output capacity of the described treatment technology of the prior art is undesirable.
In above-mentioned prior art, mostly adopt extraction process to carry out the extraction of oil, as patent CN1563306A, GB632304A and US6307077B1, the use of extraction process must relate to choosing of extraction solvent, and most extraction agents all is a chemical reagent, this quality for oil has certain influence, and also there are certain technological difficulties in removing fully of extraction agent.Chinese patent CN1714661A uses the filtration method impurity elimination; And after depickling, decolouring processing, obtain fiery numb seed essential oil.But the problem that exists in above-mentioned treating process is, though it does not use extraction process, avoided the introducing of extraction chemistry reagent to a certain extent, but because the fiery numb seed product after the squeezing is water-soluble, so must contain a certain amount of water in the oil product that after without the above-mentioned treatment process dealkalize of extraction back use, obtains, have influence on the quality of oil product equally.
Summary of the invention
Technical problem to be solved by this invention is to use and repeats squeezing process replacement chemical extraction, does not introduce any chemical reagent, Hemp Seed is squeezed for the first time the embryo sheet of back gained and handles, thereby improve greasy quality and productive rate; In addition, thus the adjusting of also carrying out suitable temperature and moisture by the Hemp Seed for the treatment of squeezing further improves greasy productive rate.
For solving the problems of the technologies described above, the invention provides a kind of fiery sesame oil fat complete processing, it comprises the steps: that (1) put into dryer with the numb seed of fire, uses hot gas flow, maintains the temperature at 50 ℃ of fiery numb seeds of oven dry, making its moisture content is 5-9%; (2) the fiery numb seed after the oven dry is directly carried out the machinery decortication; (3) Hemp Seed that the back of peeling is obtained is dried processing under 45-65 ℃ temperature, and making the moisture content in the Hemp Seed is 5-7%; (4) the described Hemp Seed after the processing of (3) step is entered modifier treatment, make the Hemp Seed temperature remain on 45-55 ℃, moisture content still is 5-7%.(5) carry out the normal temperature cold press with above-mentioned (1) to (4) Hemp Seed that step was obtained as material, temperature is 40-50 ℃ when keeping crude oil to go out sluice gate; (6) crude oil that obtains after the cold press is carried out precipitation process, and the crude oil of post precipitation is left standstill processing; (7) to the crude oil after leaving standstill after centrifugal treating, filter; (8) repeat (5) to (7) step with the embryo sheet that cold press was obtained as material, further obtain fiery sesame oil fat, the fat content in the embryo sheet is 5-5.5%.
