Description
Technical field
The present invention proposes a kind of extracting method of cat dung melon seeds oil.
Background technology
Cat dung melon (Decaisnea Insignis), has another name called short Qi Shu, Root of Farges Decaisnea, cat dung cylinder, ghost refers to plum, and Lardizabalaceae is grown thickly the upright dungarunga of fallen leaves, the tertiary period relict seeds.Yunnan Province of China, Guangxi, Guizhou, Sichuan, Shaanxi, Hubei, Hunan, Anhui, Jiangxi, Zhejiang etc. are economized all distribution, and main product is in Qin_Ba mountain areas, and among remote mountains, Niubeiliang National Nature Reserve in Shaanxi, Root of Farges Decaisnea is comparatively common.Only Ankang distribution area is just at 6667hm
2above.Fruit is berry, bluish voilet, and pericarp is containing rubber, and fruit flesh is white, and edible, also can make wine, refine sugar, its seed oil is edible, also can refine biofuel; Its root and fruit medicine.Its seed oil content is 18% ~ 22%, and be rich in insatiable hunger and close lipid acid, oil colours is yellowish limpid, has tempting fragrant.Oil edible, its taste is fragrant beautiful, being rich in nutrition, also can articles for washing processed and hair care skin-protection health products, and also can make technical oils, be a kind of important traditional oil tree.There is no extensive utilization at present.
Through retrieval, do not have to find the technical scheme identical with invention.
Summary of the invention
The technical problem to be solved in the present invention is: the extracting method providing a kind of cat dung melon seeds oil, and the utilization ratio of the method cat dung melon seeds raw material is high, and the cat dung melon seeds oil purity of extraction is high.
The technical scheme of technical solution problem of the present invention is: with cat dung melon seeds for raw material, and by peeling of peeling off after the drying of cat dung melon seeds, broken, by the cat dung melon seeds strip plate of fragmentation, strip plate is fried to dry after adding water and steaming, and supercharging squeeze, precipitate, filter that to obtain cat dung melon seeds oily.
The extracting method of cat dung melon seeds oil of the present invention, the said method by the drying of cat dung melon seeds is: dried by cat dung melon seed, makes its water content be 10% ~ 12%.
The extracting method of cat dung melon seeds oil of the present invention, the said method by the cat dung melon seeds strip plate of fragmentation is: the cat dung melon seeds by peeling off, after break process is processed as the strip plate of blank thickness 5 ~ 8 mm.
The extracting method of cat dung melon seeds oil of the present invention, the said method of steaming rear stir-fry extremely dry that adds water is: soak before strip plate being entered steamer, the charge amount of steamer wetting layer controls 80% ~ 85%, close exhaust hole, keep cooking pot airtight, in case moisture loss, wetting is 60min with steaming the base time; Carry out the drying of stir-fry base with frying pan after steaming, retaining amount during stir-fry base in pot will control 40% ~ 45%, and through frying base, drop temperature is 105 ~ 110 DEG C, and moisture content is 5% ~ 8%, and frying the base time is 30min.
The extracting method of cat dung melon seeds oil of the present invention, the method for said supercharging squeezing is: be divided into secondary to squeeze, one-level low pressure is squeezed: be less than 8% at moisture content of raw material, when temperature is lower than 5O DEG C, at pressure 5.0Mpa, at squeezing bore temperature 45 DEG C, squeeze 15 min; Two grade low-temp supercharging squeezings: supercharging makes pressure reach 15.0Mpa, at squeezing bore temperature 45 DEG C, squeezes 5 min.
The extracting method of cat dung melon seeds oil of the present invention, said intermediate processing is: removing crude oil with macrobead grouts after, then carry out crude oil precipitation, it is thin assorted that precipitation removes a part.
The extracting method of cat dung melon seeds oil of the present invention, the method of said filtration is: the crude oil after removing impurity by means of precipitation adds water and removes part phosphatide, with 5000r/min spiral type whizzer centrifugal 20min at 20 DEG C, get the transparent liquid of upper strata clear yellow and be cat dung melon processed oil.
The invention has the beneficial effects as follows:
The extracting method of cat dung melon seeds oil of the present invention, technical measures and the effect of employing are:
1, peel off and reduce wearing and tearing to production unit, improve production efficiency of equipment, improve oil pump capacity, avoid seed shell impurity effect product color, improve the quality of crude oil and cake Hectometer, and be beneficial to follow-up strip plate operation and cot comprehensive utilization, improve production environment simultaneously, realize carrying out production strictly in line with rules and regulations.
2, broken strip plate destroys cell tissue structure to greatest extent, and the oil droplet of original high dispersing is condensed in a large number; Increase material table area simultaneously, be convenient to that follow-up to carry out fully squeezing fuel-displaced.
3, stock thin and thick uniformity after strip plate, when steaming stir-fry, relatively damp and hot relatively more even, there is larger space between sheet block, creating facility for carrying out high-moisture steaming stir-fry under controlled temperature conditions.
4, high temperature wet heat treatment, increase oil cell to the perviousness of oil, grease is easy to be extracted, for the squeezing of seed and the leaching of oil create favourable condition.
5, low temperature pressing can keep the stability of unsaturated fatty acids structure and the immutableness of protein molecule in seed, substantially remains the whole nutritive ingredient of grease in cat dung melon seed, increases transparency and the color and luster of processed oil.
6, use two stage supercharging Technology in Pressing, invasion material capacity can be improved, make stock sheet block shaping further, reduce fines content, reduce oil extraction load gradually, improve oil extraction efficiency.
Therefore, the extracting method of cat dung melon seeds oil of the present invention, compared with prior art, has following beneficial effect:
1, on the Process ba-sis of cat dung melon seed belt shell squeezing, increase decortication process of peeling off, decrease the wearing and tearing of rigid shell to instrument; Broken strip plate process advan, in steaming the quick infiltration of frying moisture, shortens seed benevolence and steams the stir-fry time, ensure that the quality of lipid acid and protein in oil.
2, steam stir-fry by high-moisture, strengthen the physical properties such as plasticity-, elasticity, physical strength, thermal conductivity, weave construction of oil plant, the residual oil content in grouts can be reduced.
3, use two stage supercharging technology, squeeze in advance under a relatively little pressure, pre-squeezing terminates rear increase pressure, oil plant oil yield is improved rapidly, falls the residual oil content in few grouts simultaneously.After secondary squeezing, the Residual oil of cake is below 3%.
