Produce the method for heavy fragrant peanut oil
Technical field
The present invention relates to a kind of method of producing peanut oil, specifically, related to a kind of method that the peanut embryo sheet is produced heavy fragrant peanut oil of curing.
Background technology
At present, the preparation method of peanut oil is a lot, and has their own characteristics each, wherein, relatively Chang Yong method mainly contains two kinds: a kind of is that seeds frying machine presses, and its technology comprises that shelled peanut is put into the cylinder frying pan directly to be added and propagandize hotly, and temperature is greatly about about 500 ℃, then, machine press for extracting juice again, refining get peanut oil at last; Another kind is that steaming embryo machine presses, and its technology comprises the shelled peanut fragmentation, rolls embryo, then, the shelled peanut embryo is put into cooking pot and adopt live (open) steam to steam stir-fry, and about about 120 ℃, then, machine press for extracting juice again, refining get peanut oil to temperature at last greatly;
More than two kinds of methods in process, duration and degree of heating control is exquisite inadequately, the material sex change is incorrect, or produces burnt the paste, or can not fully ripe, its peanut oil giving off a strong fragrance of producing flavor is not enough, Jiao Huweidao is arranged, or the taste of living peanut is arranged, and mouthfeel is bad, color and luster is bright inadequately, and the energy of producing peanut oil consumption is big.
In order to overcome the above problems, people are seeking a kind of desirable technical solution always.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, thus the method for producing heavy fragrant peanut oil that providing a kind of saves energy and reduce the cost, duration and degree of heating control is moderate, the peanut oil aromatic flavour that this method is produced, both there be not Jiao Huweidao, the taste that does not also have living peanut, and transparent color and luster is vivid, and mouthfeel is good.
To achieve these goals, the invention provides a kind of method of producing heavy fragrant peanut oil, it may further comprise the steps:
Step 1, with the shelled peanut fragmentation that cleans up, then, the shelled peanut of fragmentation is rolled into the peanut embryo sheet;
Step 2, the peanut embryo sheet is put into plate dryer cure, thermal source adopts indirect steam or conduction oil, and stoving temperature is controlled at 230~280 ℃, and the time of curing was controlled at 30~50 minutes, cured pressure and was controlled at 0.3~0.5MPa;
Step 3, will take out peanut embryo sheet after curing in the plate dryer and carry out machine and press, refining again, last, obtain peanut oil.
Say that further in step 2, described stoving temperature is controlled in 250 ± 5 ℃ of scopes, the described time of curing is 40 minutes, and the described pressure that cures is controlled in 0.4 ± 0.05MPa scope.
The relative prior art of the present invention has outstanding substantive distinguishing features and obvious improvement, and specifically, this produces the method for heavy fragrant peanut oil, and heat energy loss is little in process of production, has energy-saving and cost-reducing advantage, and the material stoving temperature is controlled at about 250 ℃, is beneficial to very much the material sex change, can fully ripe, do not produce burnt the paste again, this technology makes the peanut oil aromatic flavour produce, and has not both had the taste of living peanut, does not also have Jiao Huweidao, and transparent color and luster is vivid, and mouthfeel is good.
The specific embodiment
For making technical scheme of the present invention clearer, provide the specific embodiment of the present invention below.
Embodiment one
A kind of method of producing heavy fragrant peanut oil, it may further comprise the steps:
Step 1, with the shelled peanut fragmentation that cleans up, then, the shelled peanut of fragmentation is rolled into the peanut embryo sheet;
Step 2, the peanut embryo sheet is put into plate dryer cure, thermal source adopts indirect steam or conduction oil, and stoving temperature is controlled at 235 ℃, and the time of curing was controlled at 35 minutes, cured pressure and was controlled at 0.35MPa;
Step 3, will take out peanut embryo sheet after curing in the plate dryer and carry out machine and press, refining again, last, obtain peanut oil.
Embodiment two
The difference of present embodiment and embodiment one is: in step 2, described stoving temperature is controlled at 250 ℃, and the described time of curing is 40 minutes, and the described pressure that cures is controlled at 0.4MPa.
Core of the present invention is the peanut embryo sheet adopted cures technology, makes that the sex change in the process of curing of peanut embryo sheet is moderate, makes the peanut oil aromatic flavour of producing, and has not both had the taste of living peanut, also do not have Jiao Huweidao, and transparent color and luster is vivid, and mouthfeel is good; In addition, this preparation method has been saved peanut heat time heating time, has energy-saving and cost-reducing advantage.
Should be noted that at last: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present invention; And not breaking away from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention asks for protection.
