Description
Technical field
The present invention relates to a kind of winterization method, particularly to a kind of winterization method of camellia seed oil.
Background technology
The winterization technique of existing camellia seed oil, mainly imitates the processing technology of corn oil, by by camellia seed oil continuous coo1ing to 5-8 DEG C, after growing the grain certain time, uses the solid fat of method filtering and removing of press filtration.Freezing owing to using continuously, so in crystallization process, owing to the feature for this oil product does not carries out constant temperature so that crystal formation major part is unbodied crystallization, filtration difficulty；It is demonstrated experimentally that the solid fat of the part of camellia seed oil, under the WINTERIZATION OF CORN OIL technological temperature imitating, can not thoroughly crystallize, lower temperature should be used, solid fat just can be made by freezing and crystallizing thoroughly to remove, this be also camellia seed oil after long time stored, produce secondary muddy the reason one of；Filter the method using press filtration so that fine crystallization is easy to filter, and causes product oil freezing experiment effect to decline so that winterized oil is easier to again muddy.
It is accordingly required in particular to a kind of winterization method of camellia seed oil, with the problem solving above-mentioned existing existence.
Content of the invention
It is an object of the invention to provide a kind of winterization method of camellia seed oil, for the deficiencies in the prior art, make camellia seed oil winterization effect bad, a muddy difficult problem during storing after winterization has been resolved, also solve because oil product occurs that muddiness carries out processing cost increase and the waste that secondary winterization causes, and the oily quality that secondary winterization causes declines, it is ensured that the quality of camellia seed oil after winterization.
Technical problem solved by the invention can realize by the following technical solutions:
A kind of winterization method of camellia seed oil, it is characterised in that it comprises the steps:
(1) camellia seed oil is squeezed into crystallizing tank and carry out fast precooling；
(2) camellia seed oil after precooling, after carrying out continuously and smoothly's cooling, then constant temperature；
(3) cryogenic refrigeration is carried out to the camellia seed oil after constant temperature, constant temperature near final chilling temperature；
(4) using Self-flow filtering method to filter the camellia seed oil after freezing thermostat, the camellia seed oil after filtration, through after the assay was approved, is put in storage.
In one embodiment of the invention, in described step (1), cool time is about 80min, and the temperature after quick cooling is about 18 DEG C.
Further, it is preferable that cool time is 85min, the temperature after quick cooling is 17.8 DEG C.
In one embodiment of the invention, in described step (2), at the uniform velocity cooling rate is 30min/ DEG C, and the temperature after at the uniform velocity cooling down is about 4 DEG C, and constant temperature time is 120min.
Further, it is preferable that the temperature after at the uniform velocity cooling down is 4.2 DEG C.
In one embodiment of the invention, in described step (3), cooling velocity is 60min/ DEG C, and final chilling temperature is about-4 DEG C, and constant temperature time is 580min.
Further, it is preferable that final chilling temperature is-3.8 DEG C.
In one embodiment of the invention, in described step (4), filter entrance distance crystallizing tank oil-out distance is about 5m, keeps camellia seed oil constant temperature during filtration.
Further, it is preferable that filter entrance distance crystallizing tank oil-out distance is 4.7m.
The principle of the camellia seed oil winterization method of the present invention is: camellia seed oil is squeezed into crystallizing tank and carries out fast precooling；Camellia seed oil after precooling, after carrying out continuously and smoothly's cooling, then carries out constant temperature again；Camellia seed oil after constant temperature carries out cryogenic refrigeration, constant temperature near final chilling temperature again；After thermostatic process completes, under conditions of continuing constant temperature, Self-flow filtering method is used to filter the camellia seed oil after freezing thermostat.
Due to have employed precooling, cooling constant temperature, deep cooling constant temperature and gravity flow method filtering technique, thus reduce in crystallization process produce imperfect crystal formation amount so that Gu fat is thoroughly crystallized, improve crystallization effect；Use because of the method filtering technique that flows automatically so that crystallize filter problem and have been resolved.
The winterization method of the camellia seed oil of the present invention, compared with prior art, have employed precooling, cooling constant temperature, deep cooling constant temperature and gravity flow method filtering technique, camellia seed oil crystallization effect is good, crystallization is thorough, micro-crystallization impermeable filter during filtration, thus effectively prevent the muddiness of tea seed winterized oil, improve product quality, reducing the cost doing over again caused increases and loss, it is achieved the purpose of the present invention.
The present invention can be not only used for the winterization of camellia seed oil, for the edible oil occurring similar quality problems after winterization, uses this technique equally applicable.
The feature of the present invention see this caseFigureThe detailed description of formula and following preferable embodiment and obtain and be well understood to.
Brief description
Figure 1The technological process of winterization method for the camellia seed oil of the present inventionFigure。
Detailed description of the invention
In order to make the present invention realize technological means, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with specificallyDiagram, the present invention is expanded on further.
