Abstract
To the effect that of the present invention: (1) is selected when producing walnut kernel per year, removes impurity.(2) with 55-60 ℃ emerge in worm water 10 minutes.(3) adopt the water under high pressure of 0.4-0.5MPa to wash away the kind skin on walnut kernel surface.(4) adopt 80-90 ℃ of heated-air drying walnut kernel.(5) walnut kernel is put into cold pressing expeller and squeeze walnut oil.(6) walnut crude oil standing sedimentation is 10-12 hour.(7) adopt flame filter press and microfroc filter to filter.(8) can.Main feature of the present invention is that whole technical process are carried out at normal temperatures, does not have the influence of high temperature, without any dissolvent residual, has kept the natural quality of walnut oil.
Description
Technical field
The present invention relates to the technology that a kind of grease is produced, be particularly suitable for producing of walnut oil.
Background technology
The oil content of walnut is very high, and fiber content is seldom, thus walnut oil produce the comparison difficulty.The main method of producing walnut oil at present has: the hydraulic oil press squeezing that (1) is traditional.The shortcoming of this method is that labour intensity is big, and oil yield is low.(2) screw oil expeller squeezing.The shortcoming of this method is must add walnut shell or other material in walnut kernel, has not only influenced oily quality, and has also hindered the utilization of walnut dregs.(3) water is for method.Water is with defibrination after the walnut kernel frying for method, then through converting the technology of starching processes such as stirring oil, oil separation by oscillation and producing grease.Because it is this technological temperature is higher, therefore all unfavorable to oil product and grouts.(4) organic solvent extraction such as butane.The recovery rate of this method is higher, but dissolvent residual is arranged.Simultaneously, because the content of unrighted acid is very high in the walnut oil, so than being easier to oxidation,
Summary of the invention
The objective of the invention is to solve current walnut oil and produce the middle cost height that exists, the problem of inferior quality.
Technology contents of the present invention is: (1) is selected when producing walnut kernel per year, removes impurity.(2) with 55-60 ℃ emerge in worm water 10 minutes.(3) adopt the water under high pressure of 0.4-0.5MPa to wash away the kind skin on walnut kernel surface.(4) adopt 80-90 ℃ of heated-air drying walnut kernel.(5) walnut kernel is put into cold pressing expeller and squeeze walnut oil.(6) walnut crude oil standing sedimentation is 10-12 hour.(7) adopt flame filter press and microfroc filter to filter.(8) can.
The specific embodiment
The present invention is achieved by the following technical solutions.
(1) selected when producing walnut kernel per year, remove impurity.
(2) with 55-60 ℃ emerge in worm water 10 minutes.
(3) adopt the water under high pressure of 0.4-0.5MPa to wash away the kind skin on walnut kernel surface.
(4) adopt 80-90 ℃ of heated-air drying walnut kernel.
(5) walnut kernel is put into cold pressing expeller and squeeze walnut oil.
(6) walnut crude oil standing sedimentation is 10-12 hour.
(7) adopt flame filter press and microfroc filter to filter.
(8) can.
Claims (6)
- The technology of 1 one kinds of producing walnut oil by cold pressing and cold refining method is characterized in that the concrete steps of this technology are:(1) selected when producing walnut kernel per year, remove impurity.(2) use emerge in worm water 10 minutes.(3) adopt water under high pressure to wash away the kind skin on walnut kernel surface.(4) adopt the heated-air drying walnut kernel.(5) walnut kernel is put into cold pressing expeller and squeeze walnut oil.(6) walnut crude oil standing sedimentation.(7) filter.(8) can.
- The technology of 2 a kind of producing walnut oil by cold pressing and cold refining method according to claim 1 is characterized in that, the temperature of warm water is 55-60 ℃ in the step (2).
