Abstract
The invention provides a squeezing method of peanut oil. The squeezing method comprises the steps of magnetic separation, screening, smashing, flaking, cooking, squeezing, hydration degumming, primary filtering, secondary filtering and the like, and thus finally obtaining the peanut oil. The squeezing method has the benefits that the invention provides a production method of the healthier peanut oil capable of reducing the content of phospholipids, and a good prevention effect is achieved for the problem of bacteria safety caused by a cold squeezing method.
Description
Technical field
The invention belongs to peanut oil production technology field, in particular, the present invention relates to a kind of pressing method of peanut oil.
Background technology
Peanut oil is yellowish transparent, and color and luster is limpid, fragrant, and flavour is good to eat, is a kind of more readily digested edible oil.China's edible peanut oil has quite long history.The conventional press technique of peanut oil comprises material picking, steam and fry, roll embryo, squeezing, filter, the shortcoming of prior art existence is: being namely complete full scale production process through simply filtering bright the mixing of removal after obtaining crude peanut oil, not processing accordingly for the phosphatide contained in oil product, affect mouthfeel, the health of health is also impacted.For the large-scale method for producing of some improvement traditional methods, in expressing process, take cold-press, cause growing of bacterium, safe edible is threatened.
Summary of the invention
The present invention is that the shortcoming in order to overcome above-mentioned prior art proposes, and its technical problem solved is to provide a kind of more healthy, effectively can reduce the production method of peanut oil phospholipids content.
For this reason, the invention provides a kind of pressing method of peanut oil, specifically comprise the following steps:
(1) peanut raw material is carried out magnetic separation, obtain not containing the Semen arachidis hypogaeae of magnetic impurity;
(2) by the Semen arachidis hypogaeae holding plane roto-sifter after magnetic separation, the large and small impurity in peanut and light impurity is screened out;
(3) carry out break process to the Semen arachidis hypogaeae of rotary flat sieve process, peanut is broken into 4 ~ 6 lobes;
(4) embryo is rolled to the peanut lobe after fragmentation, roll into thin and uniform embryo sheet;
(5) steam stir-fry embryo sheet, make embryo sheet reach into squeezing requirement;
(6) carrying out squeezing process to reaching into the embryo sheet of squeezing requirement, obtaining crude peanut oil;
(7) crude peanut oil is carried out hydration degum, obtain degummed oil;
(8) filter degummed oil, obtain peanut oil.
Further, the specification of rotary flat sieve described in step 2 is 18mm ╳ 22mm.
Further, described in step 4, the thickness of embryo sheet is at below 0.5mm, and embryo sheet fines content is little, oil-proof.
The invention has the beneficial effects as follows: the invention provides a kind of more healthy, effectively can reduce the pressing method of the peanut oil of phospholipids content, and have good preventive effect to the bacterium safety problem that cold-press causes.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
A pressing method for peanut oil, specifically comprises the following steps:
Magnet is utilized by peanut raw material to remove magnetic impurity in raw material;
Semen arachidis hypogaeae after magnetic separation is placed on rotary flat sieve, utilizes peanut and impurity in the difference of granular size and weight, by the relative movement at compass screen surface of peanut and impurity, remove large and small impurity in peanut and light impurity with the rotary flat sieve that specification is 18 ╳ 22;
By screening after Semen arachidis hypogaeae carry out break process, with crusher, peanut is broken into 4 ~ 6 lobes, makes it have certain granularity and meet the condition of rolling embryo, require the oil plant epigranular after fragmentation, not fuel-displaced, not agglomerating, become powder less;
Adopt single pair-roller press to roll embryo to the peanut lobe after fragmentation, roll into thin and uniform blank, make blank fines content little, oil-proof, thickness is 0.5 below ㎜;
Carry out steaming to embryo sheet to fry, destroy oil plant cellularstructure, make protein denaturation, phosphatide water-swelling, reach into squeezing requirement, improve oil yield, reduce phospholipids content;
Loading squeezing grinding tool by reaching into the embryo sheet squeezing ball, starting squeezing machine and squeezing, obtaining crude peanut oil;
Hydration degum is carried out to crude peanut oil, makes phosphatide water suction coagulative precipitation;
Degummed oil after coming unstuck to spray carries out first time and filters, and removes bright assorted and part phosphatide;
Carry out second time according to national standard to filter, the phospholipids content of peanut oil is dropped to minimum.
Claims (3)
