Description
Technical field
The present invention relates to oil-containing oil plant squeezing method of making oil, particularly a kind of puffing expression method for producing oil with low oil-containing oil-bearing material.
Background technology
Pressing with the oil-containing oil plant in the oily industry of greasy system, according to the oleaginousness difference oil plant oil plant generally is divided into and low contains oil plant and height contains oil plant, oleaginousness being called height as peanut, vegetable seed, cottonseed, sunflower seeds etc. and containing oil plant more than 25%, adopt pre-press for extracting juice-leaching legal system oil usually; Oleaginousness be lower than 25% be called low oil-containing oil plant as soybean, rice bran etc., adopt pre-treatment direct leaching system oil usually.
Milling process is to apply physical pressure grease is separated from oil plant, does not relate to adding any chemical substance, and the various compositions in the expressed oil keep comparatively complete, but that shortcoming is an oil yield is lower.Lixiviation process is selected the solvent that meets relevant national standard for use, utilizes the character of dissolving each other of grease and selected solvent, contacts and its extraction is dissolved out with grease in the solid oil plant of handling by solvent, and remove solvent in the grease with strict process.Compare with milling process, Residual oil is few in its dregs of rice of leaching legal system oil, the oil yield height, and tooling cost is lower, working condition is good; Oil resource is fully utilized.
Along with the raising of health of people consciousness, people especially became to safety, the nutrition of edible oil to food and pay close attention to more, and country also pays close attention to this, and China formulated and issued and implemented the new standard of edible oil in 2004.New standard stipulates that all small packages edible oils must indicate " milling process " or " lixiviation process " production technique on label, and dated raw material is " transgenosis " or " non-transgenic ", and the product of Zhu Minging must not sold on market.At present, the edible oil of plain press production is higher by about 30% than leaching the edible oil price of producing.Therefore, though the oil made from the oil plant milling process is subjected to people's welcome; It is lower that but shortcoming is an oil yield, and the added value of squeeze cake is lower; Especially to the less oil expression of industrial scale enterprise,, be difficult to overcome above-mentioned shortcoming, be difficult for dominating the market by the traditional technology oil expression.
Summary of the invention
The purpose of this invention is to provide a kind of puffing expression method for producing oil with low oil-containing oil-bearing material, be particularly suitable for the less producer of some industrial scales, utilize vegetable oil material to produce the squeeze cake of high-quality pressed oil and high added value, in market, has significant competitive power to overcome the high difficulty of oil processing industry small-scale production cost, to make.
Purpose of the present invention is realized by following technical scheme: the present invention is a kind of puffing expression method for producing oil with low oil-containing oil-bearing material, and described low oil-containing oil plant comprises with rice bran and soybean being two class oil plants of representative, it is characterized in that comprising the step of following order:
1) impurity in the oil plant is removed in cleaning;
2) modified, described oil plant is carried out the adjusting of temperature and moisture;
3) extruding puffing, with described oil plant pushed, expanded;
4) kill enzyme, drying, extruding, oil plant after expanded are killed enzyme and drying;
5) squeezing, dried oil plant squeezing is fuel-displaced.
When with the soybean being the oil plant oil expression, after the step 1) cleaning, also the oil plant after the cleaning is carried out step 1A) fragmentation, and then carry out step 2) modified; In step 2) modified after, also oil plant is carried out step 2A) strip plate, oil plant is rolled into the material base that thickness is 0.3～0.5mm, and then carries out the step 3) extruding puffing.
At step 1A) in the fragmentation, the particle size after cracking of oil plant soybean is 4～6 lobes.
At step 1A) in the fragmentation, the oil plant powder that the fines content of the oil plant that is broken is controlled to be by 20 orders/inch sieve is no more than 10%.
In step 2) modified in, refining temperature is 50～70 ℃, the moisture content of material after modified is 9%～12%.
In the step 3) extruding puffing, the pressure of heating steam is 0.6～0.8Mpa, and drop temperature is 100～110 ℃, expanded coefficient 1.2～1.4 (promptly the ratio of the diameter of expanded material and nib exit diameter is together following).
In the step 3) extruding puffing, being kept moisture by expanded material when advancing bulking machine is 9～12%, and keeping moisture when going out bulking machine is 11～14%.
When step 4) was killed enzyme, drying, temperature was at 105～120 ℃, and after the drying, the moisture of oil plant remains on below 6% to meet the squeezing requirement.
When step 5) was squeezed, moisture when oil plant goes into to press kept 3%～6%, press in the cake Residual oil remain on 7% or below.When step 5) was squeezed, the temperature when oil plant goes into to press was 100～110 ℃.
The explanation of such scheme:
Step 1) cleaning: according to low oil-containing oil plant and the difference of impurity on physical propertiess such as granularity, proportion, shape, condition of surface, hardness, magnetic, gasdynamics, adopt method and relevant devices such as screening, selection by winnowing, gravity separation and magnetic separation, with the Impurity removal in the oil plant.After cleaning, must not contain large-scale impurity such as stone, iron are assorted, the rope made of hemp, wormwood.
Step 1A) fragmentation: for big beans oil plant, also need fragmentation after the cleaning, make oil plant have certain particle to meet the strip plate condition; Surface-area after the oil plant fragmentation increases, and is beneficial to the transmission of temperature and moisture when modified, and modified effect improves.Require to answer epigranular after the oil plant fragmentation, not fuel-displaced, not agglomerating, become powder less.For big beans oil plant, can adopt toothed roll crusher to carry out fragmentation.
Step 2) modified: the big beans oil plant after rice bran class or the fragmentation is carried out the adjusting of temperature and moisture, make its moisture be fit to later extruding puffing, and have suitable elastoplasticity, fines content and roll banding phenomenon during with the minimizing strip plate guarantee the base tablet quality.
Step 2A) strip plate: will hang down the oil-containing oil plant such as soybean is squeezed into laminar base sheet with crushing roll.
Step 3) extruding puffing: after a series of physics, the chemical actions such as wet, the heat effect of mechanical effect such as the meat sheet is squeezed in extruder, rubs, shears, pressurization and the steam that sprays into and frictional heat, the oil cell of oil plant is thoroughly destroyed, grease fully exposes, and objectionable impurities obtains passivation.Carry out extruding puffing with the oil plant extruder, at the end of extrusion screw, high temperature, high pressure oil plant come out sharply to expand because of release suddenly through die head, obtain loose porous and extruding puffing oil plant that intensity is high is beneficial to the raising of later squeezing oil yield.
Step 4) is killed enzyme, drying: because of through expanded again the squeezing after its Residual oil of squeeze cake low, quality good, can be used for milk cow feed etc., but must be earlier through killing enzyme, make that urease meets urease content national standard in the feed in the squeeze cake, livestock has eaten just and can not suffer from diarrhea.In addition, the moisture in the oil plant of extruding puffing generally can't satisfy the requirement of squeezing machine to moisture, and therefore, expanded oil plant must carry out drying, moisture is dropped to the requirement of satisfying the squeezing step.This process can be carried out in five layers of evapo-separated machine, above three layers kill urease, lower two layers is carried out the drying of expanded material.
Step 5) squeezing: with squeezing machine the squeezing grease in the expanded material is gone out, as crude oil; Residual oil is generally below 7% in the squeeze cake.
Squeezing contains a certain amount of crumb in the crude oil, must remove the gred before oil and fat refining, so crude oil needs remove most crumb through dragveyer, obtains squeezing edible vegetable oil remove bits such as a spot of crumb again through leaf-type filter after, sends to refining again.
Squeeze cake can be directly used in the raw material of making to produce feed after crushed, and added value of product increases.
In traditional single pressing system oil process,, often adopt " steam and fry " process in order to obtain the good pressability of blank.The oil plant temperature of " steaming and frying " process is up to more than 120 ℃, and for up to 30～40 minutes, this process not only consumed a large amount of electric power and steam, and made proteinic quality be subjected to great destruction.Therefore greatly reduce the quality of squeezing crude oil and press for extracting juice cake.The present invention replaces traditional steaming and frying technique with the full oil-containing puffing technique of low oil-containing oil plant, make oil plant moment in tens seconds finish puffing process, avoided oil plant to steam proteinic excessive sex change in the stir-fry process at long-time high temperature, reduced the loss of Methionin, improve the protein mass of squeeze cake, efficiently solved the unfavorable problem that long-time high temperature brings in traditional steaming and frying technique.
Secondly, the enzyme effect of going out of the short time high temperature high pressure of puffing can make squeezing crude oil phosphorus content significantly reduce, and the crude oil color shoals and is easier to decolouring, has improved the quality and the oil and fat refining rate of squeezing crude oil.
Once more, after a series of physics, the chemical actions such as wet, the heat effect of mechanical effect such as the base sheet of oil plant is squeezed in the oil plant extruder, rubs, shears, pressurization and the steam that sprays into and frictional heat, the oil cell of oil plant is thoroughly destroyed, grease fully exposes in the cell, form expanded microtexture, be very beneficial for oil is squeezed out from oil plant, improve oil yield, objectionable impurities obtains passivation.At the end of extrusion screw, high temperature, high-pressure material come out through die head, and because of release suddenly, material sharply expands and obtains loose porous and extruding puffing oil plant that intensity is high.The squeeze cake of extruding puffing oil plant is loose, and fines content is little, and squeeze cake easily is shaped; Also can increase the treatment capacity of squeezing machine, reduce the squeezing machine power consumption, reduce mechanical wear.
