Description
Technical field
The invention belongs to utilization of agricultural resources utilization technical fields.It is related to the high-efficiency cleaning of a kind of full price camellia seed oil and Tea Saponin
Extracting method.
Background technique
Tea seed (Oil-Camellia seed) is the distinctive woody oleiferous plants of China.Tea seed oil content is 18% -35%,
Camellia seed oil mid-oleic is the highest edible vegetable oil of current oleic acid content between 74% -85%.Contain in camellia seed oil
There are the functional components such as carotenoid, sasanguasaponin, tea polyphenols, squalene and fat soluble vitamin abundant.Contain in tea seed
There is 6% -11% protein, is potential forage protein.Also contain 10% -15% oil tea saponin in tea seed, oil tea saponin is one
The natural nonionic surfactant of kind, is soluble in hot water and ethyl alcohol.It is widely applied in industries such as medicine, daily use chemicals, pesticides.
China generallys use squeezing method and organic solvent lixiviation process to process tea seed, obtains crude oil tea-seed oil and tea seed
The dregs of rice.Squeezing method under the conditions of 100 DEG C -140 DEG C of temperature, is utilized by the tea seed with shell through broken, strip plate and after steaming stir-fry
Hydraulic or screw oil expeller squeezes out the camellia seed oil in clinker, while obtaining crude oil and tea-seed pancake.In high temperature and pressure
Under the conditions of nutrition in tea seed, especially functional component will receive a degree of destruction, in addition, containing in crude oil
Certain amount influences the oxious component of camellia seed oil quality and safety, could be edible after needing further to refine.In refining
It will cause fat-soluble nutrients composition different degrees of destruction and loss in the process.
High temperature and pressure in expressing process can also make tea seed protein serious degenerative, reduce the utility value of protein.
In addition, band shell liquefaction is also easy to produce strong carcinogen 3 under the high temperature conditions, 4- BaP becomes the security risk of current camellia seed oil.
Organic solvent lixiviation process is that have excellent dissolution to camellia seed oil using normal hexane No. six molten Ji as the main component
The characteristics of property, tea-seed pancake is impregnated repeatedly with this solvent, will wherein remaining camellia seed oil be extracted, Residual oil therein can be made
It is reduced to 2% or less.But containing high boiling organic solvent residual composition, (such as 3,4- BaP etc. is carcinogenic in crude oil obtained
Object) and other more non-oil compositions, the quality and safety of Extractive crudeoil is seriously affected, it is directly edible to cause to be poisoned.Therefore it soaks
After crude oil tea-seed oil must pass through the physics such as stringent degumming, depickling, decoloration and deodorization and chemical method refining out, it can be only achieved
Edible oil quality and safety standard requirement, in crude oil refining process fat-soluble nutrients substance and functional component be destroyed or with
Raffinate loses together.The antioxidant content loss for being especially able to maintain camellia seed oil stability is serious therefore refined
Camellia seed oil in the have to antioxidant of addition synthesis be just able to maintain the stability of camellia seed oil, to guarantee it in the shelf-life
It is rotten that oxidative rancidity does not occur inside.The loss that will also result in the high-quality camellia seed oil in part in above-mentioned refining process, wastes treasured
Expensive camellia seed oil resource.The waste water and waste residue of exhaust emission environment are understood in refining process simultaneously.
Leach camellia seed meal in contain good tea seed protein, but in leached tea oil slag containing 50% or more tea seed episperm, and
15% or so oil tea saponin has seriously affected the digestive function and palatability of animal, therefore cannot use directly as feed,
Therefore cause the waste of a large amount of quality plant albumen.Since Tea Saponin has bactericidal effect, there is inhibition to the growth of edaphon
Effect destroys edaphon environment, it is dead from effectively absorbing soil nutrient composition to prevent crop, therefore can not directly make
Fertilizer application.Therefore, traditional tea seed processing method can neither obtain the camellia seed oil of the ecosystem of high-quality, high nutrition,
The high-quality resources such as tea seed albumen and the oil tea saponin in tea seed can not be made full use of.
In recent years the water substitution that many researchers propose processes tea seed with aqueous enzymatic method, to obtain the tea seed of high-quality
Oil.
But water substitution and aqueous enzymatic method at present there is also unusual distinct issues, i.e., can generate during the extraction process
A large amount of water phase, that is, process water, wherein containing such as protein, oil tea saponin, polysaccharide, flavones functional component, therefore, directly
Discharge will cause the waste and environmental pollution of resource.If process water enter sewage plant processing, due to the antibacterial of oil tea saponin with
Bactericidal effect can destroy the microbial population in biochemical reaction tank, reduce the effect of water process.Since biochemical reaction tank is to oil tea
The degradation of saponin is unobvious, and the water being discharged from sewage treatment plant still contains oil tea saponin, not only will appear more stable property
Foam, and will affect aqueous bio.If handled using chemical method, not only higher cost, also be will cause new
Pollution, and the structure of oil tea saponin can be destroyed, influence its application value.In addition, as using conventional distillating method evaporator man
Water in skill water, evaporating lower object although is thick Tea Saponin, but impurity is more, and purity is low, moreover, distillation energy consumption is high, economically not counting.
Therefore, problem brought by the processing of process water greatlys restrict water substitution and aqueous enzymatic method technology in tea seed processing technology
Popularization and application in research and production.

Its course of work is to make steam pressure and temperature through vapour compression machine adiabatic compression using the secondary steam come out from evaporator
It increases, is re-used as the heating room that heating steam is sent into evaporator, using as heating steam, condensing heat release, feed liquid is made to maintain boiling
State is risen, and heats steam itself and is then condensed into recycle-water.It the system electricity consumption or is only needed in addition to start up, when normal operation
Few live steam is supplemented, the steam to be discarded originally in this way is just fully utilized, and recycles latent heat, improves thermal effect
Rate, economy are equivalent to the tens of efficiency-timed of multiple-effect evaporation.
In the present invention, ethyl alcohol will be distilled out in obtained pure tea saponin liquid from step (6) in step (7).If with
The water that step (5) evaporates in dense tea saponin liquid directlys adopt MVR evaporator like that distill ethyl alcohol, comes out from separator secondary
Steam is alcohol vapour.Compress alcohol vapour directly with vapour compression machine come when improving its pressure and temperature, it may occur that quick-fried
It is fried, it is thus impossible to directly be distilled to recover ethyl alcohol using MVR evaporator.In order to make full use of MVR evaporator to save significantly on steam
The characteristics of, while avoiding the problem that explosion may be caused when alcohol vapour directly compresses, the present invention uses closed loop high-efficiency evaporating
Device is distilled to recover alcohol, obtains B alcohol liquid and B strong tea saponin is starched.The working principle of closed loop high-efficiency evaporator is to utilize working medium
Heat exchange is carried out by evaporator and condenser to complete heat absorption and exothermic process.Closed loop high-efficiency evaporator is steamed by MVR

Vapour) it is mutually isolated, thermal effect compressor acts only on working medium, and two independent systems complete heat by evaporator and cold-hot machine
Exchange.When operation, the working medium (gas phase) of low pressure, low temperature in heating system is by becoming high pressure, high temperature after compressor compresses
Working medium (gas phase), into condenser (heater namely on MVR evaporator), that is, cold burden (alcohol-containing tea saponin liquid) into
Enter evaporator.Temperature increases and boils and generate alcohol vapour after alcohol-containing tea saponin liquid absorbs the latent heat of working medium, passes through separation
Device isolates secondary alcohol vapour.High pressure, the latent heat exchange of liquid phase working fluid of high temperature are cooled to high pressure, low temperature liquid phase to cold burden
Working medium.High pressure, low temperature liquid phase working fluid after expansion valve, since the reduction of pressure is transformed into low pressure and the lower liquid of temperature
Phase.Then, low pressure, low temperature liquid phase working fluid enter evaporator (being condenser for secondary alcohol vapour) with from separator
The secondary alcohol vapour separated carries out heat exchange, is changed into low pressure, temperature after absorbing latent heat contained by secondary alcohol vapour
Higher gas-phase working medium is spent, thermal effect compressor compresses is entered back into high pressure, high temperature refrigerant (gas phase) and enters new circulation.Secondary wine
Smart steam by latent heat exchange to low pressure, cryogenic fluid after be discharged from condenser, become B alcoholic solution.In addition, secondary alcohol steams
Vapour is condensed by cryogenic fluid, is not needed in addition to consume cooling water, is significantly reduced the usage amount of water in technical process.
Closed loop high-efficiency evaporator completely avoids compressing a possibility that exploding because of alcohol steam, solves compressor
It is unable to the technical bottleneck of the secondary alcohol steam of direct weighting, the potential of secondary steam can be made full use of as MVR evaporator, is subtracted
The consumption of few live steam, has significant energy-saving benefit.
Compared with prior art, the present invention has the advantages that are as follows:
1, in the method for the present invention, dilute tea soap of later step is all made of with step (2) in step (1) (in addition to first time extracts)
Plain liquid, step (3) is in addition to first time is using fresh deionized water, remaining deionization for using recycle-water and supplementing on a small quantity
Water.Therefore, it is not required to add again any other all using water as extractant in entire camellia seed oil and oil tea saponin extraction process
The chemical assistant of organic or inorganic.Ensure that the flavor of mentioned camellia seed oil is not destroyed in this way, vitamin E, carotenoids
Element, the fat-soluble functional component of squalene fully enter oily phase, and are retained in camellia seed oil.Water is both to extract in the process
The medium of camellia seed oil, and be the solvent for extracting oil tea saponin, camellia seed oil and Tea Saponin are by simultaneously from camellia seed kernel slurry
It is extracted, a water is dual-purpose, and one mentions more product.The investment of equipment is greatly saved, reduces process procedure, improves the effect of extraction
Rate has saved extraction cost.
2, in the method for the present invention, camellia seed oil and oil tea saponin use reverse extracting mode, in step (1) and step (2)

As long as simple impurity elimination dehydration, natural fat-soluble nutrients composition and anti-oxidant composition have obtained sufficient reservation, have become name
The advantages of symbol full price camellia seed oil product in fact, and be also equipped with good antioxidative stabilizer, long shelf-life.
4, in the method for the present invention, the raising of tea saponin liquid concentration is using the low-down MVR evaporation of energy consumption in step (5)
The secondary steam of low temperature, low pressure is transformed into high pressure, high-temperature steam by vapour compression machine, makes dense tea saponin liquid after continuation of insurance by device
Boiling is held, and evaporates moisture.Due to hardly needing newborn steam heating during it, only need that compressor is driven to be transported
The electric power turned.Its operating cost significantly reduces, and reduces the investment for adding cauldron, reduces the exhaust gas and waste residue of boiler
Discharge.Therefore, also very advantageous to protection environment.Compared with using simple reduced pressure method in the past, significantly reduce
Energy consumption.If single effect evaporator evaporates the steam that one ton of water needs 1.1 tons or so, and generates one ton of steam and need to consume about 80M3It
Right gas, with natural gas average price for 4 yuan/M3It calculates, then steam cost per ton is 320 yuan.Therefore, every one ton of water of evaporation needs
320 yuan of fuel cost or more.If using MVR evaporator, since MVR evaporator is in addition to initial operating stage needs steam to heat, then
The secondary steam of low temperature, low pressure is transformed into high pressure, high-temperature steam by vapour compression machine to provide heat by process, is kept dense
The boiling of tea saponin liquid.Therefore, power consumption needed for only consumption drives vapour compression machine evaporates one ton of water and takes around consumption 23-70
Degree electricity, by every 0.8 yuan of calculating of degree electricity, one ton of water of every evaporation only needs 18.4-56.0 first.Energy-saving effect be apparently higher than before institute
There is method.
5, in the method for the present invention, pure Tea Saponin slurry obtained in step (6) is efficiently to be steamed using closed loop by step (7)
It is distilled to recover alcohol in hair device, secondary alcohol steam is realized using the compression and evaporation to working medium by additional closed loop
The recycling of latent heat, generated secondary alcohol steam cannot be directly with steaming during having well solved alcohol distillation in the past
Vapour compressor carries out the problem of compression boosting, heating, and the heat source of evaporator can be converted by making secondary alcohol steam equally.
6, in the method for the present invention, alcohol liquid will be added (by A alcohol liquid in A Tea Saponin obtained in step (5) slurry in step (6)
Supplement), the solubility property of the impurity such as starch, dextrin, protein in the solution is reduced, contamination precipitation therein is removed,
And obtain clarified solution.Therefore, A alcohol liquid is both the alcohol precipitation agent of the impurity such as lysate and starch, dextrin, the protein of Tea Saponin,
Treatment process is greatly simplified in this way, decreases sediment to the adsorption loss of Tea Saponin.
7, the reverse extracting mode of the method for the present invention water phase extracts camellia seed oil and oil tea from camellia seed kernel slurry simultaneously
Saponin, to camellia seed oil be not only able to maintain its distinctive fragrant, but also vitamin E, carotenoids in camellia seed kernel
The lipid soluble ingredients such as element, squalene can be sufficiently retained in camellia seed oil, be the ecosystem camellia seed oil of full price.It obtains oily
Rate can achieve 93% or more, be higher than traditional oils tea seed oil extract method about 5%.The purity of obtained Tea Saponin powder reaches simultaneously
60% or more.
8, ethyl alcohol used in the present invention does not contact completely with grease, avoids the influence to camellia seed oil quality, and
Using closed loop evaporator recovered alcohol, not only the rate of recovery is high, but also low energy consumption.The recycling of process water is then returned using MVR technology
