Abstract
A lower-temperature original preliminary pressed peanut oil extracting technique method is produced according to the following technique methods: filtering and removing the impurity of the pignuts, carrying out braking, then using dried cold air to cool, cracking into semi-grains after cooling, removing the red skins and peanut embryos, putting the semi-grains of the peanuts uniformly into a tempering boiler to temper, carrying out preliminary pressing on the semi-grains of the tempered peanuts, carrying out rough filtering, primary fine filtering and secondary fine filtering on the preliminary pressed peanut cake to obtain a finished product of refined original preliminary pressed peanut oil, carrying out secondary pressing and third pressing on the preliminary pressed peanut cake, carrying out rough filtering, primary filtering and secondly fine filtering on the secondary and third pressed crude peanut oil to obtain finished product of refined original pressed peanut oil. The invention has the advantage of separating the preliminary pressed peanut oil and the secondary and third pressed peanut oil to carry out fine filtering and extraction respectively, thus obtaining the high-quality refined original preliminary pressed peanut oil and the refined original pressed peanut oil which meets the demands of people to the various grades of the peanut oil and maintains all the nutrition matters in the peanuts.
Description
Technical field
The invention belongs to a kind of oil expression method, particularly a kind of technique for extracting low-temperature protogenesis extra virgin peanut oil.
Background technology
At present, domestic peanut oil expression production technology adopts milling process more, and milling process is divided into high temperature squeezing and cold pressing again.The general technology process of high temperature squeezing is: cleaning is broken, softening, strip plate, steaming stir-fry, squeezing, fuel-displacedly go out cake.Wherein, at strip plate, steam operations such as stir-frys, squeezing and add HTHPs, temperature can reach 110 ℃～125 ℃, owing to temperature is higher, thereby, bigger to the destruction of nutriment in the peanut, influence the quality of product oil.In order to solve the problem that the high temperature squeezing exists, people adopt the cold pressing method to produce peanut oil, and cancellation is steamed and fried operation, and reduce the temperature of squeezing, to improve the quality of peanut oil.Chinese patent application 200510017990.0 discloses a kind of " cold pressing peanut oil is produced the method for peanut protein synchronously ".This method comprises following operation: 1, shelled peanut screening back is being dried below 90 ℃, 2, shelled peanut after the oven dry is sloughed scarlet with machine, 3, the shelled peanut of sloughing scarlet after the oven dry is broken into 2～10 lobes with roller pulverizer, 4, it is 10～80 ℃ that the peanut lobe is placed on the temperature range of regulating in the modified pot, water content is 5～8%, 5, raw material after modified is carried out a press for extracting juice with twin-screw oil mill, the peanut oil of squeezing out flows into oil sump, it is fragment below 8 millimeters that remaining peanut cake is ground into granularity once more, 6, one raw material that presses after pulverizing is carried out two presses for extracting juice, two peanut oil of squeezing out also flow into oil sump, Sheng Xia peanut cake enters micronizer after crushed at last, makes 100～1000 purpose peanut protein powders.This patent application mainly is a kind of process of cold pressing peanut oil, has added a step of producing peanut protein on the basis of squeezing peanut oil.From this patent application of production technology is not the process of a pure cold pressing peanut oil, because in baking operation, bake out temperature has reached 90 ℃, in modified operation, maximum temperature in the modified pot has also reached 80 ℃, this inevitably also can destroy part nutrition material in the peanut, influences the quality of finished product peanut oil.In addition, this process is pressed one and two peanut oil that press lump together and carry out essence and filter extraction, a press for extracting juice and two peanut oil that press are not separately extracted separately, do not make full use of express oil from peanuts excellent quality, nutritious characteristics, produce more high-grade high-quality peanut oil, thereby, can not satisfy the demand of people to high-grade high-quality peanut oil, the peanut oil of different levels can not be provided for people simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is, overcome the finished product peanut oil quality that existing cold pressing peanut oil exists, the problem that class is not high, provide a kind of and do not destroy nutriment in the peanut, and can produce the technique for extracting low-temperature protogenesis extra virgin peanut oil of high-grade high-quality peanut oil.
The present invention produces according to following process:
1, shelled peanut is carried out screening and removing impurities, remove jejune flat grain, granule, and, remove mould grain and impurity, select full shelled peanut through hand picking;
2, the shelled peanut of selecting is baked and banked up with earth, baking and banking up with earth temperature is 50～60 ℃, and the time is 20～25 minutes, and the moisture content of shelled peanut is reached below 4%;
3, the shelled peanut after will baking and banking up with earth cools off with dry cold wind at once, and the temperature of cold wind is 5～10 ℃, and shelled peanut is cooled to 15～20 ℃, so that slough scarlet;
4, cooled shelled peanut is become half with the broken grain of roll-type crusher machine, remove scarlet, and remove the peanut plumule;
5, with half even equal putting in the modified pot of peanut, kettle temperature is 40～60 ℃, and moisture content is controlled at 4～6%;
6, half of the peanut after modified carried out just press, just the temperature of pressing is controlled at 50～60 ℃, and screw speed is 15～20 rev/mins, obtains expressing peanut crude oil just;
7, first expressing peanut crude oil is carried out coarse filtration, obtain coarse filtration peanut oil;
8, the coarse filtration peanut oil after the coarse filtration is carried out the smart filter of one-level, obtain semi-finished product and just express oil from peanuts;
9, the semi-finished product after the smart filter of one-level are just expressed oil from peanuts carry out the smart filter of secondary, obtain refining primary just the expressing oil from peanuts of finished product;
10, carry out two after the peanut cake fragmentation after will just pressing and press and three presses for extracting juice, two press and three temperature of pressing are controlled at 50～60 ℃, and screw speed is 15～20 rev/mins, obtains two press for extracting juice and three expressing peanut crude oils;
11, coarse filtration is carried out in two presses for extracting juice and three expressing peanut crude oils, obtain coarse filtration squeezing peanut oil;
12, the squeezing of the coarse filtration after coarse filtration peanut oil is carried out the smart filter of one-level, obtain semi-finished product squeezing peanut oil;
13, the semi-finished product squeezing peanut oil after the smart filter of one-level is carried out the smart filter of secondary, obtain the refining primary squeezing peanut oil of finished product.
The invention has the advantages that:
1, will just express oil from peanuts and two press and three express oil from peanuts and separate, carrying out smart separately filter respectively extracts, obtained high-quality refining primaryly just express oil from peanuts and making with extra care primary squeezing peanut oil, especially refining primary just expressing oil from peanuts, made full use of the excellent quality that just expresses oil from peanuts, nutritious characteristics, comprised the most of nutriment in the peanut, satisfied the demand of people high-grade high-quality peanut oil, the peanut oil of different levels also is provided for people simultaneously.
2, bake and bank up with earth, modified and the squeezing production process in, temperature is controlled at below 60 ℃ all the time, has guaranteed that all nutritions in the peanut can be not destroyed, has kept the complete nutrients matter in the peanut, thereby has obtained nutritious peanut oil.
3, removed the peanut plumule after the shelled peanut fragmentation, made the taste of peanut oil purer, mouthfeel is more aromatic.
