Description
Technical field
The invention belongs to edible oil or fatty technical field, and in particular to a kind of ripe squeezing walnut oil method.
Background technology
Walnut oil is to use walnut kernel as raw material, the vegetable oil squeezed.Belong to edible oil.The fat content of walnut
Up to 65%-70%, shelter have first of woody oleiferous plants, there is the good reputation of " oil depot on tree ".Carried and selected the essence using modern crafts, this is just
It is walnut new generation product --- walnut oil.Walnut oil is to choose high-quality walnut to do raw material, and uses technique leading in the world
The natural fruit oil juice for producing out.In the international market, walnut oil is described as " east olive oil ", equally enjoys and disappears with olive oil
The person of expense favors.
The ripe squeezing method of walnut oil, be by walnut it is heat aging after, be made using oil press physical squeezing, but this side
Method curing difficulty is high, and temperature is too high to be easy to make walnut local temperature is too high to cause walnut to be charred, and has a strong impact on walnut oil quality；
Temperature is too low and causes walnut curing not thorough, influences oil yield.
The content of the invention
In order to solve the above problems, the invention provides a kind of ripe squeezing walnut oil method.
The present invention is achieved through the following technical solutions：
A kind of ripe squeezing walnut oil method, specially following steps：
（1）Purchase high-quality walnut kernel and crush
Dried in the shade after the walnut kernel of buying is cleaned up, be subsequently placed in freezing processing 30-40 minutes in -15 DEG C of freezers, make at once
Smashed with pulverizer, then fragment walnut kernel is placed in baking oven, cold wind drying cycle is dried to water content below 0.5%；By walnut kernel
Crushed after freezing, improve walnut kernel fragility, reduced and crush difficulty, while avoid the fuel-displaced wave for causing raw material in crushing process
Take, then dried using baking oven cold wind, reduce the content of moisture impurity；
（2）The maturation process of walnut kernel
By step（1）Obtained fragment walnut kernel is placed in the walnut oil that same batch has been squeezed, and the fragment walnut kernel and walnut oil are pressed
Mass ratio 3:1 mixing, is again heated to 110-115 DEG C of insulation, and is stirred continuously using agitator, after 5-8 minutes, pours into squeezing together
Squeezing is handled in oil machine；Fragment walnut kernel is heated using walnut oil, first without removal of impurities demand, avoids the production of new impurity
It is raw, while using walnut oil immersion heating, control temperature is more convenient, fragment walnut kernel is uniformly heated, will not produce and be charred shape
Condition, finally it is placed in oil press and squeezes, because walnut kernel is uniform by thermal maturation, oil yield is higher, and quality is more preferable, and fragrance is denseer；
（3）Walnut oil cleans
The walnut oil of squeezing is sieved while hot and stands 60-80 minutes after 200 mesh, 4/5ths of upper strata fluid is then taken, obtains one
Secondary removal of impurities oil；Then remaining fluid is separated impurity layer, is obtained secondary removal of impurities oil using the centrifuge processing 90-120 seconds；
Once clean oily, secondary removal of impurities oil described in merging, and produces walnut oil.
Further, step（2）Described to be heated to 110-115 DEG C of insulation, heating means heat for 1200MHz microwaves.
Further, step（3）The centrifugal treating, centrifuge speed 1000-2000r/min.
Beneficial effects of the present invention：Crushed after walnut kernel is freezed, improve walnut kernel fragility, reduced and crush difficulty, together
When avoid the fuel-displaced waste for causing raw material in crushing process, then dried using baking oven cold wind, reduce the content of moisture impurity；
Fragment walnut kernel is heated using walnut oil, first without removal of impurities demand, avoids the generation of new impurity, while soak using walnut oil
Heating, is more convenient control temperature, and fragment walnut kernel is uniformly heated, will not produce the situation of being charred, finally be placed in oil press and press
Squeeze, because walnut kernel is uniform by thermal maturation, oil yield is higher, and quality is more preferable, and fragrance is denseer.By experiment, carried using the present invention
A kind of ripe squeezing walnut oil method of confession, reduce moisture during ripe squeezing, the generation for the impurity such as walnut is charred, contain crude oil impurity
Amount by the 2.1% of prior art is reduced to less than 1.0%, simultaneously because walnut kernel curing is uniformly, thoroughly, the oil yield of walnut kernel by
The 38.5% of prior art is improved to more than 39.9%, of great advantage to improving Business Economic Benefit.
