Description
Technical field
The present invention relates to a kind of production method of edible vegetable oil, specifically a kind of life of Luzhou-flavor edible vegetable oil
Production method.
Background technique
Currently, the processing method of Luzhou-flavor perilla herb oil, linseed oil, rapeseed oil is mostly raw material or decortication shell seed after cleaning
Benevolence directly fries seed, and the product oil made after squeezing, refining, this kind of oil plant has Ben Peng when preparing Luzhou-flavor edible oil mostly
(α) pyrene content is high, oil colours and control are inconvenient, alpha-linolenic acid reduces in peel inefficient and perilla herb oil and linseed oil
Problem.
Such as application No. is 201510160311.9 to disclose " a kind of giving off a strong fragrance vegetable seed oil producing method ", and rapeseed is dry de-
Skin, stir-fry seed dust, squeezing, refined filtration obtain, and fry again since rapeseed first being peeled, the direct high temperature of seed benevolence is easy to cause Ben Peng (α)
The rising of pyrene, and in the technical solution when frying seed using while fry while add water adjust method, will lead to plus water it is irregular, part
Possible stir-bake to brown is cooked, though the Luzhou-flavor incense oil taste of this method production is dense, oil colours is deeper, and has oily Zhong Ben Peng (α) pyrene, pesticide
The exceeded problem of residual content.Therefore, it is necessary to a kind of new production methods to solve the above problems.
Summary of the invention
The purpose of the present invention is to solve above-mentioned technologies to ask, provides a kind of easily-controllable simple process, equipment investment and operation
The production of at low cost, shallower, Ben Peng (α) pyrene of product colour or pesticide concentration is low, nutritive value is high Luzhou-flavor edible vegetable oil
Method.
The technical scheme comprises the following steps:
(1) thick cleaning: oilseeds are subjected to thick cleaning removal impurity, the oil seed raw material is purple perilla seed, rapeseed, linseed
One of；
(3) it eluriates, extract: the oilseeds after thick cleaning being sent into continous way wash mill and are washed to eluriate the seed surface that deoils
Remaining pesticide, plaster and uniformly dampening are wet, then extract using press filtering machine, control out the material of press filtering machine
Moisture is weight percent 10%-15%；
(4) it roasts, raise cigarette, decortication: eluriating the material after extracting and enter the training stir-fry of rotary roaster, be then fed into shelling dress
Set it is interior peeled and raise cigarette, peeling rate 80%-90%, skin-containing rate is weight percent 4%-5% in benevolence；
(5) thermophilic squeezes: the material after Jing Yangyan, decortication is directly entered oil press and is squeezed, and enters to squeeze material temperature degree 60-80
DEG C, obtain crude oil and press cake；
(6) refined filtration dewaxes: crude oil being precipitated and is cooled down, then obtains product oil after flame filter press filters dewaxing twice.
In the step (2), the training fries temperature control at 160-180 DEG C, and roast times are controlled in 20-40min.
In the step (2), the moisture content that control training cooks after frying is weight percent 4%-6%.
In the step (4), the oilseeds after training is fried are entered in dejacketer using wind model, and the dejacketer includes
Inner wall is coated with the cyclone separator of wear-resistant material and vibrating screen, the oilseeds trained after frying with blowing device are first sent into rotation
Wind separator is hit, rub decortication, and the blowing effect that vibrating screen is re-fed into after sedimentation in blowing device vibrates Bian Yangyan below
And separation of hull and kernel.
In the step (6), crude oil is precipitated into 12-24h, oil temperature is made to be cooled to 20-30 DEG C, through the primary mistake of flame filter press
Filter；Then oil strain will be crossed and be cooled to 0-6 DEG C in being slowly stirred down, crystallize wax in oil, at low temperature through flame filter press into
Second of filtering and removing wax of row, obtains product oil.
In the step (6), when the primary filtering, one layer of fine cloth of cushioning on the filter cloth of flame filter press；Described
When secondary filter, one layer of filter paper of cushioning on the filter cloth of flame filter press.
The problem of for background technique, inventor improve the prior art as follows:
(1) elutriation is being increased before roasting, is being extracted: in order to avoid stir-bake to brown usually requires to add one when dried material is roasted
Add water during gauge water is adjusted, and watering still roasts before either roasting in the prior art, exists plus water is irregular
The problem of, cause partial material surface overly moist, partial material surface overdrying, partial material can be heated coking when roasting in this way, lead
Zhi Ben Peng (α) pyrene content rises, and also influences the mouthfeel and color of oil product obtained.In response to this problem, after inventor is to thick cleaning
Oilseeds using eluriate by the way of, on the one hand adequately eluriate can effectively remove oilseeds pesticide remained on surface, plaster, solve
Certainly the problem of pesticide residue, oil quality is improved, on the other hand, elutriation process is to make the process of material uniform wet, is subsequent
It roasts and gets ready, to, although increasing panning procedure, reduce roast simultaneously without adjusting is added water when roasting
Operation difficulty, material coking generation caused by adding water uneven when avoiding the problem that roasting；Further, the material water after elutriation
Divide content still excessive, moisture extra in material can be squeezed out by way of extracting at this time, its water content be made to meet the later period
The requirement roasted.
(2) first roast rear peeling: inventor study carefully grind in find, oilseeds are first peeled roasts that there are various problems: a afterwards,
Oilseeds decortication is difficult, and due to not heated, benevolence skin is tightly combined, and decortication is difficult, in order to guarantee peeling rate, it is still desirable to first dry
Decortication and separating treatment are carried out with machinery again, increases production cost and operation difficulty；B, when oilseeds are peeled, it is impossible to complete benevolence
Skin separation, the oilseeds benevolence after decortication necessarily contain the fragment of a small amount of seed peel, these broken little particle particles generated are heavy when roasting
Product is frying furnace bottom, it is easier to which being heated excessively to burn to carbonize generates Ben Peng (a) pyrene, also can further influence the color and matter of oil product
Amount.C roasts that temperature is higher, and fragrance is stronger when producing Luzhou-flavor oil product under the premise of material not coking, and mouthfeel is better, but
In the prior art, usually the seed benevolence after decortication is directly roasted, in this case, roasting temperature can not be excessively high, otherwise seed benevolence pole
Easy coking, but if temperature is too low, then the fragrance of product is bad.To the needle above problem, inventor uses and first roasts rear peeling
Method, advantage have three；A roasts rear peeling, and seed peel is different with the coefficient of expansion of the seed benevolence after heated, after frying as band shell melon seeds
It is easier to peel off the same, the intimate-association state of benevolence skin is destroyed, and is easier to remove, therefore using wind model enter to hit and frictional
It is obtained with high peeling rate in shelling and sedimentation integrated device, exfoliant effect is good, and due to roasting the water in rear shell
Divide by high temperature removal, quality is lighter, therefore in later separation, is easier to separation of being dried.Seed Renhe leather shell is dried through vibration, is raised
Cigarette separates, and skin-containing rate can easily control 4%-5% in benevolence, to reduce the residual of seed peel fragment in material, increases squeezing
Oil yield, further increase oil quality；B due to first roasting rear peeling, and passes through before roasting and eluriates technique, and material is almost
There is no small particles such as soil, impurity or seed peels, material keeps size uniform, therefore energy thermally equivalent reduces when roasting
The generation of small particle coking problem, training stir-fry process is easier to control, avoids thus bring variety of problems.C, belt leather roast
When, the seed benevolence wrapped up in seed peel is not contacted directly by seed peel protection with high temperature, is heated more uniformly, and pass through panning procedure material
Surface humidification uniformly, while roasting temperature so as to improve, will not make seed benevolence that coking occur, even if seed peel surface is slightly burnt
Change will not influence seed benevolence, and seed peel can remove in subsequent decortication process, so that the fragrance of product oil is stronger, i.e.,
The generation for avoiding Ben Peng (α) pyrene, also avoiding contained alpha-linolenic acid reduces, and improves the quality of product oil.In the present invention,
It is preferred that training fries temperature control at 160-180 DEG C, more preferably 170-180 DEG C, roast times are controlled in 20-40min.
(3) dejacketer can be used existing common dejacketer, in the present invention, it is preferred to use cyclone separator and band
It is made of the vibrating screen of blowing device, since oilseeds are fried by training, ripe shell is brittle, thus can easily pass whirlwind wind from device
It is peeled, is peeled high-efficient to it using the principle hit and rubbed, and be able to achieve continuity operation, through whirlwind wind from device point
Vibrating screen is sent into after object oil sedimentation from after to dry in vibration, can play the mesh that cigarette is raised to material and separates skin therewith
, realize separation of hull and kernel, separative efficiency is high.The whirlwind wind coats wear-resistant material from device inner surface, plays to material impacting
The purpose to rub simultaneously improves separation of hull and kernel efficiency.
Further, filtering twice is carried out using flame filter press to crude oil to dewax, and further define the side of dewaxing
Method, acquired product oil is as clear as crystal, has better shelf sense organ and preservation term.
The utility model has the advantages that
Present invention process is simple, operation controls good simplicity, controllability, equipment investment and low energy consumption, product oil Ben Peng (a) pyrene
