Abstract
The invention provides a kind of high grade camellia oil refinery practice, can produce high grade camellia oil with conventional equipment, it is mainly included the following steps that：A, crude oil is prepared：B, soap is taken off；C, wash；D, decolourize；E, it is deodorized；F, degreasing；G, degreasing oil obtains product oil through refined filtration.The process modification feature of the present invention is：Working condition is easily controllable, and product quality is stable, and oil yield is high, while pollutant emission is few in production process.
Description
Technical field
The present invention relates to tea seed deep process technology, and in particular to a kind of refinery practice of camellia oil.
Background technology
Oil tea,（Latin literary fame Camellia oleifera Abel.）Alias：Ribes tree, tea oil tree, white flower tea；Oil tea
Belong to Theaceae, evergreen dungarunga.Oil tea is Dabie Mountain of China, Fujian, Jiangxi, Hunan（Changning）Etc. ground special product, because its seed can squeeze
Oil（Tea oil）It is edible, it is therefore named.Tea oil color clear flavor incense, nutritious, storage tolerance, it is high quality food oil.Camellia oil also known as tea seed
Oil, tea pear oil（Fujian is commonly called as）, Wild camellia seed oil, camellia seed oil, the tea oil seeds of trees oil.
According to indexs such as oil product outward appearance, impurity content, nutritional ingredients, camellia oil is divided into different grades.Each factory of stage division
Family's standard is different, it is generally the case that high with oil product nutritional ingredient, property is stable, outward appearance is well high grade tea oil.High grade tea
Oil can be used as cosmetics of super quality raw material in addition to edible, and added value is high；At present, high grade camellia oil production technology is still without system
One standard.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of high grade camellia oil refinery practice, can set with conventional
Standby to produce high grade camellia oil, oil yield is higher, and process conditions are easily controllable.
In order to solve the above technical problems, the high grade camellia oil refinery practice of the present invention, comprises the following steps：
A, crude oil is prepared：
（1）Seed selection：Select color and luster it is normal, without go mouldy, free from admixture and full tea seed, dry；
（2）Coarse crushing：Step（1）Gained tea seed is crushed with disintegrating machine；Then tea seed episperm and tea in material are made by selection by winnowing
The ratio of seed benevolence reaches 25%：75%.
（3）Drying：By step（2）Gained tea seed is put into frying pan, and stir-frying to tea seed water content is under the conditions of 60~65 DEG C
9%；
（4）It is fine broken：By step（3）Resulting material is broken for into tea seed powder；
（5）Steam bran cake：By step（4）Resulting material was placed in food steamer, with vapor boiling 0.5~1 hour；Then make
Cake；
（6）Squeezing：By step（5）Resulting material cake is put into hydraulic oil press and squeezes to obtain crude oil；
B, soap is taken off
Crude oil obtained by step a is kept for 35 ~ 40 DEG C, under conditions of stirring, by the 0.2-0.3% of crude oil weight add concentration be 40 ~
50% citric acid, sampling detection acid value in whipping process；Continue to heat up, when temperature rises to 45 DEG C, add unsaturated carbonate soda
Liquid, continue stir and slowly heat up, after neat soap is substantially formed oiling weigh 3~6% water, stop stirring when temperature rises to 80 DEG C
Mix；Soap stock, sampling Detection are released after standing 16 hours；The addition of the carbonic acid soda lye is the 0.1%~0.3% of crude oil weight；
C, wash
Oil is warming up to 80~85 DEG C after releasing soap stock, the sodium chloride solution for then adding 3-6% mass ratioes is washed, chlorination
Sodium solution amount of water is the 6~9% of crude oil weight, continues to stir 20~30min with 20~30r/min after adding, and it is heavy then to stand
Form sediment 4 hours, Zao Shui is washed in releasing；This step sodium chloride solution is repeated to wash 1~3 time；Supernatant liquor is exported, removes lower floor's soap stock；
It is standby tea oil must to be washed；
D, decolourize
Gained washing tea oil is heated up to 90-100 DEG C, is stirred in heating, is added and account for the de- of washing tea oil weight 8-20%
Toner, stir, filter, remove decolorising agent, obtain decolouring tea oil；The decolorising agent includes activated carbon, carclazyte, diatomite；
E, it is deodorized
Oil after washing is heated to 140 DEG C, steam is passed through in tea oil, forces lower floor's oil to upper strata to be circulated；Continue to heat up, make
Tea oil temperature is incubated 2~4 hours to 245 DEG C；
F, degreasing
Room temperature is cooled to, then the tea oil by obtained by freezes 48 hours under the conditions of 0~5 DEG C as freezing equipment, takes supernatant；
G, degreasing oil obtains product oil through refined filtration.
The process modification feature of the present invention is：Working condition is easily controllable, and product quality is stable, and oil yield is high, simultaneously
Pollutant emission is few in production process.
Embodiment
The high grade camellia oil refinery practice of the present embodiment, comprises the following steps：
A, crude oil is prepared：
（1）Seed selection：Select color and luster it is normal, without go mouldy, free from admixture and full tea seed, dry；
（2）Coarse crushing：Step（1）Gained tea seed is crushed with disintegrating machine；Then tea seed episperm and tea in material are made by selection by winnowing
The ratio of seed benevolence reaches 25%：75%.
（3）Drying：By step（2）Gained tea seed is put into frying pan, and stir-frying to tea seed water content is under the conditions of 60~65 DEG C
9%；
（4）It is fine broken：By step（3）Resulting material is broken for into tea seed powder；
