Description
Technical field
The present invention relates to a kind of camellia oil production technical field, and in particular to the refining treatment technology of camellia oil.
Background technology
Camellia oil contains substantial amounts of unrighted acid and oleic acid, rich in protein and multivitamin, especially also contains
Leukotrienes that is abundant needed by human and can not synthesizing.But camellia oil, because refining techniques is improper, is got rid of in refining process
Abandon harmful substance while can also lose substantial amounts of nutriment, cause the reduction of nutriment species or content drop in camellia oil
It is low.Therefore, it is necessary to research and develop a kind of camellia oil of the obtained high-quality of camellia oil refining treatment technology.
The content of the invention
It is an object of the invention to provide a kind of refining treatment technology of camellia oil.
A kind of refining treatment technology of camellia oil, comprises the following steps：

Cool after 40min-45min, the oil after decolouring is mixed with decolorising agent, then filtered, except the decolorising agent in deoiling, removed
Bleached oil after pigment, residual soap and metal oxide；
(7) it is deodorized；After bleached oil is heated into 160 DEG C -180 DEG C, 0.03-0.04% citric acids are added, are heated to be deodorized
It is deodorized after temperature into deodorizing tower, is cooled to 35-45 DEG C, produces deodorised oil；
(8) dewax, deodorised oil and cooling agent heat exchange, be cooled to 4-5 DEG C and enter crystallizing tank, crystallization filtering.
Further, in step (1) addition of phosphoric acid be camellia oil oil weight 0.3%-0.5%, the pressure being separated by filtration
Power is 300-400MPa.
Further, the mass fraction of sodium hydroxide solution is 9%-11% in step (2).
Further, the temperature of hot soft water is 80 DEG C -95 DEG C in step (3), and dosage is the 6%- of light phase edible vegetable oil oil weight
9%.
Further, oil-water separating agent is 9%-10% sodium chloride solutions in step (4).
Further, in step (6), decolorising agent include carclazyte, bamboo charcoal, aluminum oxide, diatomite, silica gel, carclazyte, bamboo charcoal,
Aluminum oxide, diatomite, the weight ratio of silica gel are 3：4：2：1：3.
Further, deodorization temperature is 210-220 DEG C in step (7), and deodorization vacuum maintains 260-275Pa, is deodorized
Duration 5-6h.
The advantage of the invention is that：Technological parameter is appropriate, and alkali refining temperature and concentration of lye are beneficial to adjustment acid value, ensure camellia
The stable Storage and high-quality of oil, will not cause nutrient composition content to be greatly reduced, and deodorization temperature is very big less than 230 DEG C of energy
Ensure that vitamin E is not destroyed to limit；A variety of decolorising agents are used in combination with the ratio and can quickly and efficiently removed；Dewaxing
When, the chilling temperature will not make unsaturated fat acid crystal, avoid unrighted acid from losing.
