Description
Technical field
The invention belongs to walnut oil production fields, and in particular to a kind of production method of walnut oil.
Background technology
Walnut contains abundant nutritive value, and walnut kernel contains protein 15% or so, reaches as high as 29.7%, fatty
About 63%, 76.34% is reached as high as, and saturated fatty acid, that is, myristic acid, palmitic acid and stearic acid total amount are less than in walnut oil
10%, and the oleic acid, linoleic acid, leukotrienes and arachidonic acid total amount in unsaturated fatty acid are up to 90%, are necessary to human body
Aliphatic acid.This has a large amount of unsaturated fatty acid of different degrees of health-care effect, especially high concentration per capita to the various ages
Presence, it is highly beneficial for brain tonic.
But the mode of the existing usual high temperature squeezing of walnut oil, high-temperature high-pressure expressed oil is relatively easy to, but impurity is more, need to be through height
Temperature and chemical method processing, high temperature are easily destroyed nutriment and functional characteristic in walnut oil again, and generate such as trans acids oil
Fat etc. is unfavorable for the impurity of health；Walnut oil also is by the way of cold press, but single cold press can make walnut kernel
The oil come of squeezing out is not thorough, and nutritional ingredient can not be comprehensively developed, and can not be utilized walnut comprehensively, be led to the production of walnut oil
Rate is low, while there is the nutriment for not squeezing out largely and in walnut.
Invention content
It is an object of the invention to：To solve walnut oil caused by the oil that walnut kernel is squeezed out in the prior art is not thorough
The problem of low yield, provides a kind of production method for the walnut oil that oil productivity is high.
The technical solution adopted by the present invention is as follows：
A kind of production method of walnut oil, the production method include the following steps：
S1：High-quality walnut is chosen, cleans surface, and sterilize；
S2：Shelling and separation of hull from kernel；
S3：Walnut kernel is put into lye and is removed the peel；
S4：Walnut kernel after peeling is rinsed well and dried with clear water；
S5：Walnut kernel is placed in mechanical Oil press, first of pressed oil and first dregs of fat are obtained by high pressure cold press；
S6：First dregs of fat are placed in squeeze in Oil press and are squeezed, second cold press is obtained by squeezing cold press
Oil and second dregs of fat；
S7：Second dregs of fat are placed in Spire oil manufacturing device and are crushed, the cold press of third road is obtained by spiral cold press
Oil；
S8：First of pressed oil, second pressed oil and third road pressed oil are collected, is filtered, just oil strain is obtained；
S9：The just oil strain is placed under vacuum condition, nitrogen charging is stood；
S10：It is filtered using fine filtering device, obtains finished product.
In said program, the step S5, specially：
It is pressurizeed by PLC control machinery Oil presses, is that first time pressurize goes out when pressure reaches the first default value
Oil；Second of pressurization, when pressure reaches the second default value, second of pressurize is fuel-displaced；Third time is pressurizeed, when pressure reaches the
When three numerical value, third time pressurize is fuel-displaced；Pressurization, the fuel-displaced process n times of pressurize are repeated up to fluid can not be extruded, obtain first of cold press
Oil and first dregs of fat.
In said program, cold press temperature described in described step S5, S6, S7 is 18-25 DEG C.
In said program, the time stood in the step S9 is 7-15 days.
In said program, the step S10, specially：
S101：Decoloration filtering processing is carried out to first oil strain；
S102：Using accurate filter, remaining tiny impurity in fluid is filtered.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
The walnut oil of output of the present invention by screening, shelling and separation of hull from kernel, peeling, cleaning, drying, multiple high pressure cold press,
Spiral cold press, extruding cold press, coarse filtration, nitrogen charging, totally ten procedures is effectively guaranteed core to refined filtration to obtain finished product walnut oil
The quality of peach oil；The nutritional ingredient that can be effectively retained in walnut kernel makes in walnut oil rich in unsaturated fatty acid and abundant micro-
Secondary element；The oil yield that walnut oil greatly improved, by oil yield from its existing about 50% be increased to about 90%；Mouth simultaneously
Feel faint scent nature, without bitter taste.
