Abstract
The invention discloses a method for pressing oil from vegetable seeds. The method comprises: selecting vegetable seeds by winnowing, washing the selected vegetable seeds with water, frying the washed vegetable seeds, pressing oil from the fried vegetable seeds, and performing filtration, oil melting and layering so as to obtain a product oil. In the screening process, tertiary screens are adopted, so that residual oil amount in cakes is effectively reduced to the minimum; besides, the quality of the cakes is higher, and unhulled rice is added in the oil pressing process, so that oil in the vegetable seeds is refined furthest; in the oil melting process, an upper layer of oil in an oil melting pool is used as the product oil, so that the quality of the oil is effectively improved; salt water is added to the oil melting pool, so that dephosphorization effect can be achieved, and the quality of the product oil is high. The method disclosed by the invention is simple in preparation process, and the prepared oil is high in purity, and free of any impurities or any chemical auxiliaries.
Description
Technical field
The present invention relates to edible fat production field, particularly relate to the method for a kind of vegetable seed oil expression.
Background technology
Rapeseed oil is commonly called as rape oil, is the liquid of the transparent or semitransparent shape pressing gained with the seed of rape, golden yellow color or pale brown.Rape oil is one of China's main edible oil, also be the third-largest vegetables oil in the world, together with soya-bean oil, sunflower seed oil, plam oil, be listed as the large grease in the world four, traditional oil-producing technique of vegetable seed mainly adopts disposable direct Technology in Pressing, main preparation process is Semen Brassicae campestris-cleaning-softening-strip plate-steaming stir-fry-squeezing-crude oil-filtration-edible vegetable oil, but in this process oil be not maximized extract, at present, the method producing rapeseed oil is a lot, but prepares that fuel-displaced purity is not high, poor quality.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of method that vegetable seed extracts oil, and the method for this vegetable seed oil expression has the content technology that maximizes the oil refined in vegetable seed and obtains that the quality of oil is high, purity is high.
In order to solve the problem, technical scheme of the present invention is the method for a kind of vegetable seed oil expression, and its preparation process is as follows:
1) selection by winnowing, sends into the vegetable seed of collection in blower fan and carries out selection by winnowing process, or utilize natural wind to carry out selection by winnowing process;
2) wash, vegetable seed is carried out washing process, then carry out drying and processing;
3) seed is fried, to through step 2) vegetable seed after process carries out the process of stir-fry seed, makes the surface temperature of vegetable seed reach 110 DEG C;
4) extract oil, process of entering to extract oil is sent in oil press zhai to the vegetable seed after pulverizing, obtains just squeezing rapeseed oil and vegetable seed slag, subsequently first slag rapeseed oil was sent in filtering basin, vegetable seed slag is collected out;
5) filter, by the first hot pickled mustard tube seed oil cooling in filtering basin, through tertiary screen process, the first squeezing rapeseed oil sieved is sent in storage pool, is not collected by the impurity of sieve;
6) carburetion process, first squeezing rapeseed oil after filtering is carried out carburetion process, first stirs 15 minutes, then add saline 15 minutes, the quality of the salt solution added is 3% ~ 5% of the quality of just squeezing rapeseed oil in chemical oil pool, and the mass concentration of salt solution is 3% ~ 5%;
7) layering, there will be oily demixing phenomenon after the first squeezing rapeseed oil after carburetion process leaves standstill for some time, is transported in finished room by upper strata oil, carries out extracting, bottling and can obtain processed oil; Lower floor's oil is transported in substandard products room.
Further, described step 4) the first squeezing rapeseed oil collected also is provided with a cryopreservation step before being sent to filtering basin, and be sent in refrigerating chamber cool 2 ~ 3h by just squeezing rapeseed oil under the condition of-3 ~-1 DEG C.
Further, described step 5) in tertiary screen comprise first sieve, second sieve, tertiary screen, wherein first sieve is 8 orders, and second sieve is 80 ~ 100 orders, and tertiary screen is 180 ~ 200 orders.
Further, described step 6) in after filtration step and be provided with a stating step before carburetion process, the first squeezing rapeseed oil after filtering is left standstill 20min, then carries out carburetion process.
Further, described step 6) in the quality of salt solution that adds be 4% ~ 5% of the quality of just squeezing rapeseed oil in chemical oil pool, the mass concentration of salt solution is 4% ~ 5%.
Beneficial effect of the present invention: adopted tertiary screen, effectively makes the resid amount in cake reach minimum, and add paddy in oil expression process, makes that the oil in vegetable seed is maximized to be refined out, makes the quality of cake higher simultaneously; With the upper strata oil in chemical oil pool as processed oil, effectively improve the quality of oil; Put into salt solution in chemical oil pool and can have dephosphorization effect, make that the processed oil quality that obtains is high, purity is high, simultaneously in whole process without any chemical assistant, ensure that the green ecological of product, meet present people's demand.
