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 and refers to plum, the Lardizabalaceae upright dungarunga of fallen leaves that grows thickly, the tertiary period relict seeds.All there is distribution in the provinces such as Yunnan Province of China, Guangxi, Guizhou, Sichuan, Shaanxi, Hubei, Hunan, Anhui, Jiangxi, Zhejiang, and main product clings to mountain area in the Qin, 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, edible, also can make wine, refine sugar, and its seed oil is edible, also can refine biofuel; Its root and fruit medicine.Its seed oil content is 18%～22%, is rich in insatiable hunger and closes lipid acid, and 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, also can make technical oils, be a kind of important traditional oil tree.There is no at present extensive utilization.
Through retrieval, there is no to find the technical scheme identical with invention.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of extracting method of cat dung melon seeds oil is provided, 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: the cat dung melon seeds of take is raw material, peel off after cat dung melon seeds is dry peeling, fragmentation, and by broken cat dung melon seeds strip plate, strip plate is fried to dry through adding after water steams, and supercharging squeezes, precipitates, filters that to obtain cat dung melon seeds oily.
The extracting method of cat dung melon seeds oil of the present invention, saidly by the dry method of cat dung melon seeds is: cat dung melon seed is dried, and making its water content is 10%～12%.
The extracting method of cat dung melon seeds oil of the present invention, the said method by broken cat dung melon seeds strip plate is: the cat dung melon seeds by peeling off, after break process is processed as the strip plate of base sheet thickness 5～8 mm.
The extracting method of cat dung melon seeds oil of the present invention, the said rear extremely dry method of frying of water steaming that adds is: before strip plate is entered to steamer, soak, the charge amount of steamer wetting layer is controlled at 80%～85%, close exhaust hole, keep cooking pot airtight, in case moisture loss, wetting is 60min with steaming the base time; After steaming, with frying pan, fry base dry, the material stock amount while frying base in pot will be controlled at 40%～45%, and through frying base, drop temperature is 105～110 ℃, 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 squeezing, one-level low pressure squeezing: be less than 8% at moisture content of raw material, temperature is lower than in the situation of 5O ℃, at pressure 5.0Mpa, squeeze at 45 ℃ of bore temperatures squeezing 15 min; Two grade low-temp superchargings squeezings: supercharging makes pressure reach 15.0Mpa, squeeze at 45 ℃ of bore temperatures squeezing 5 min.
The extracting method of cat dung melon seeds oil of the present invention, said intermediate processing is: remove crude oil with macrobead grouts after, then carry out crude oil precipitation, it is thin assorted that precipitation is removed 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 to remove impurity by means of precipitation adds water and removes part phosphatide, with 5000r/min spiral type whizzer centrifugal 20min at 20 ℃, 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 the 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, realization is carried out production strictly in line with rules and regulations simultaneously.
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; Increased 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 more even, between sheet piece, there is larger space, for carry out high-moisture steaming stir-fry under temperature control condition, create facility.
4, high temperature wet heat treatment, increases oil cell to oily perviousness, and grease is easy to be extracted, for favourable condition has been created in the squeezing of seed and oily leaching.
5, low temperature pressing can keep the stability of unsaturated fatty acids structure and the immutableness of protein molecule in seed, has substantially retained the whole nutritive ingredients 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, can improve invasion material capacity, make the further moulding of stock sheet piece, reduce fines content, reduce gradually oil extraction load, 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 technique basis of cat dung melon seed belt shell squeezing, increase the decortication process of peeling off, reduced the wearing and tearing of rigid shell to instrument; Broken strip plate technique is conducive to steam the quick infiltration of frying moisture, shortened seed benevolence and steamed the stir-fry time, has guaranteed the quality of lipid acid and protein in oil.
2, by high-moisture, steam stir-fry, the physical propertiess such as the plasticity-of enhancing oil plant, elasticity, physical strength, thermal conductivity, weave construction, can reduce the residual oil content in grouts.
3, use two stage supercharging technology, under a relatively little pressure, squeeze in advance, pre-squeezing finished rear increase pressure, and 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%.
