Description
Technical field
The present invention relates to peanut oil processing technology of preparing field, and in particular to a kind of low temperature is baked and banked up with earth squeezing and prepares peanut oil
Method.
Background technology
The production method of existing peanut oil has hot moulding, organic solvent extraction etc., and existing production method has following lacking
Point：Though the 1, hot moulding liquefaction yield is high, the local flavor of oil is good, and hot moulding makes the protein denaturation in peanut, the peanut dregses after squeezing
Mainly as feed and fertilizer, comprehensive utilization of resources benefit is low；2nd, No. six solvent naphthas, just oneself are used organic solvent extractionprocess more
The organic reagent oil and grease extracting such as alkane, petroleum ether, oil yield is higher, but Product Safety is low, there is edible safety hidden danger.Separately
Outward, the processing method of traditional shelled peanut is mostly shelled peanut to be carried out into fried or dry stir-fry and then is seasoned again, this processing side
The fat content of the shelled peanut that method is processed is high, and long-term a large amount of eating can cause the diseases such as fat, initiation cardiovascular.
The content of the invention
For above-mentioned problem, the present invention proposes a kind of low temperature and bakes and banks up with earth the method that squeezing prepares peanut oil, including
Screening, low temperature are baked and banked up with earth, low temperature extract oil and the step such as purify, and are screened and are baked and banked up with earth degreasing by reasonable, improve the safety of peanut oil
Quality, obtained peanut oil nutrient health, fragrance is more preferably strong, and the strict control technological temperature of the present invention, to temperature-sensitive in peanut
Property material influence it is smaller, be effectively retained local flavor and the nutrition of peanut.
In order to realize above-mentioned purpose, the present invention uses following technical scheme：
A kind of low temperature bakes and banks up with earth the method that squeezing prepares peanut oil, and step is as follows：
1) screen：By purchase fresh shelled peanut screened at least twice, a magnetic separation, the shelled peanut for obtaining is in temperature
10 DEG C, spread 5-6h under conditions of humidity 15-25%；
2) low temperature is baked and banked up with earth：By step 1) in the shelled peanut that obtains be placed in and bake and bank up with earth in case, 1- is baked and banked up with earth under the conditions of 45-50 DEG C
2h, with 20 DEG C of temperature, the distinguished and admirable rapid cooling of humidity 45-75% after taking-up, then removes shelled peanut outer layer scarlet；
3) low temperature oil expression：By step 2) in the shelled peanut that goes after detestaing loaded using gauze bag component, by least two
Secondary heating twin rollers compression process, is then placed in oil press, squeezes fuel-displaced under the conditions of 45-50 DEG C, 20-22MPa, squeezes
Gauze bag is taken out after 25-35min, crude oil is obtained；
4) purify：By crude oil through precipitation, filtering, purification, final finished peanut oil is obtained final product.
Preferably, step 1) in magnetic separation operation and screening operation alternately.
Preferably, step 1) in screening use rotary flat sieve.
Preferably, step 2) cooling blowing during constantly shelled peanut is stirred.
Preferably, step 2) in shelled peanut outer layer scarlet using shelled peanut scarlet dry method peeling machine remove.
Preferably, step 3) in heating twin rollers heating-up temperature be 95-120 DEG C, roller spacing be 0.8-1.2cm, roller speed
It is 1-1.2m/min.
Preferably, step 3) can to reprocess be local flavor shelled peanut snacks for shelled peanut in the gauze bag that takes out.
Due to using above-mentioned technical scheme, the beneficial effects of the invention are as follows：The preparation of peanut oil of the present invention uses physics
Squeezing, including screening, low temperature are baked and banked up with earth, low temperature extract oil and purify etc. step, screens and bakes and banks up with earth degreasing by reasonable, improves peanut
The safe mass of oil and local flavor shelled peanut, obtained peanut oil nutrient health, fragrance is more preferably strong, and the strict control work of the present invention
Skill temperature, it is smaller on heat-sensitive substance influence in peanut, it has been effectively retained local flavor and the nutrition of peanut.Low temperature is used after baking and banking up with earth
It is distinguished and admirable, accelerate to make up partially aqueous amount while cooling, the influence of the hot-rolling compacting in later stage is reduced, while phosphatide can be reduced effectively
Content, improves oil yield.
