Description
Technical field
The present invention relates to a kind of from from tea waste, extracting the technology of tea saponin.
Background technology
Tea saponin is a kind of nonionogenic tenside of excellent property, emulsification, foaming, lubricated, surely there is good performance aspect such as bubble and decontamination, is widely used in material of construction, pesticide processing, aquaculture, food, light industry, medicine, wool spinning, industry such as knitting; Can be used for making various types of emulsifying agents, agricultural chemicals, rubber, extinguish material, cinestrip, Shampoo ﹠ Conditioner, foaming Steel Concrete, prawn culturing agent etc., can develop 180 surplus kind of series product, potentiality to be exploited is huge, market outlook are wide.About the extraction and the application of tea saponin, China has very years of researches and practice, and conclusion is got up, and 4 kinds of methods are arranged usually, and both water seaoning, absorption method, microwave/light wave dry method were extracted and the organic solvent extraction method.
Water seaoning is that tea-cake dregs is ground into meal, and 5 times hot water are added in the meal, soaks 2h under 30～35 ℃ of temperature, and the lixiviate number of times is twice.Soak the back centrifugation, fertilizer is made in the residue oven dry.Merge vat liquor, add 2% flocculation agent, and leave standstill after being heated to certain temperature, separate and remove throw out, adopt the method for vacuum concentration that vat liquor is concentrated into 30 degree Beaume, get the liquid saponin.This production technique, equipment are simple, less investment, but yield rate is low, and the concentrate drying process consumes high, belongs to eliminating technology.
Absorption method adopts water or solvent lixiviate tea waste, with impurity such as the glycolipid in inorganics or the organic resin adsorbing and extracting liquid, juice, pigments, again through lixiviate, concentrate finished product.This method cost height yields poorly, and has pollution problem.Produce exhausted inorganics and organic resin difficult treatment in enormous quantities.
Organic solvent extraction method 1, solvent pairs substep extraction and separation process are removed grease remaining in the grouts with oil-dissolving solvent earlier, and the degreasing grouts are used 70%～95% organic solvent extraction saponin again, and the extracting solution process is filtered the back compression and concentrated, and gets thick saponin.2, single solvent extraction separating technology, this method obtains tea oil and two kinds of products of tea saponin simultaneously with a set of equipment, two kinds of solvents.Cake of camellia oleifera seeds is crushed to certain fineness, makes saponin dissolve leaching, again with stirring solvent mixing, extracting and separating, crude oil is isolated in clean then liquid layering, and remaining liquid gets thick saponin through concentrated, impurity elimination, reconcentration.Decolouring then, the dry finished product that gets.Its technology is loaded down with trivial details.Production process is used the very easily manufacturing environment pollution of multiple solvent.
The method of process for abstracting theasaponine by microwave/light wave dry, it is fluctuation, high frequency, thermal property and a non-thermal property of utilizing little/light wave, and cake of camellia oleifera seeds is carried out dry process, lixiviate then, extraction, decolouring, drying are obtained the tea saponin finished product.Very convenient because of handling with microwave/light wave at a few hectogram raw materials of testing laboratory, tens tons in process of production, hundreds of ton have been handled just inconvenient with microwave/light wave, and consumes energy is huge.Moreover still want lixiviate, extraction, decolouring, drying after handling, its effect is not fairly obvious, has pollution problem simultaneously yet.
The present invention is in order to overcome the weak point that prior art exists, a kind of technology of extracting tea saponin from tea waste to be provided, this technology have the product purity height, of light color, yield rate is high, energy-conservation, joint consumption, pollution-free, environmental protection, advantage such as easy to operate.
Summary of the invention
The present invention is in order to overcome the weak point that prior art exists, a kind of technology of extracting tea saponin from tea waste to be provided, this technology have the product purity height, of light color, yield rate is high, energy-conservation, joint consumption, pollution-free, environmental protection, advantage such as easy to operate.
Technical solution problem of the present invention adopts following technical scheme:
Extract the technology of tea saponin from tea waste, comprise raw material pulverizing, oven dry, lixiviate, separation, concentrate, its process characteristic is:
Described raw material pulverizing is meant raw material pulverizing to granularity 1-3mm particulate state;
Described oven dry, be meant with the raw material after pulverizing deliver to automatic cooking pot dried through 10-30 minute to the raw material water content less than 7%;
In the described lixiviate step, solvent is selected from the ethanolic soln that concentration is 75%-85%, and extraction time is 1-1.5 hour; Twice of lixiviate.
Extract the technology of tea saponin from tea waste, its process characteristic also is:
In the described lixiviate step, the temperature of extraction solvent is 40-50 ℃.
The weight ratio of described extraction solvent and tea waste is controlled at 3: 1-4: 1, promptly solvent be raw material 3-4 doubly.
In the described enrichment step, adopt the evaporation of secondary long tube, 50-80 ℃ of one-level temperature, 70-95 ℃ of secondary temperature; Automatically surplus temperature concentrates 2-4 hour naturally after importing vacuum concentration pot after 2-4 minute.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention is crushed to starting material leached tea oil slag or tea cake the particulate state of 1-3mm, breaking in the past, people always think that starting material are thin more, the idea of the easy more leaching of saponin, original technology is machined to 40 orders-120 order powdery with starting material, processes carefully to 300 orders, though the saponin dissolution rate after the pulverizing has been accelerated in addition even with it, but increased slag liquid separation difficulty degree, simultaneously impurity such as a large amount of xylogen is present in the leach liquor, causes that saponin purity is low, color is dark, follow-uply also wants the removal of impurity, decolouring.The present invention has overcome former defective workmanship, slag, liquid separate easily, product purity height, light, reduced follow-up decolouring link, reduced tooling cost simultaneously, every day with tens of ton sometimes up to a hundred tons of tea cakes or the dregs of rice particulate state that is crushed to 1-3mm with former technology starting material are machined to 40 orders-120 order or 300 order powderies are compared the processing charges that will save thousands of units.
2, the present invention adopts stoving process, makes the starting material water content be no more than 7%, because of the excessive solvent of raw material moisture content is difficult for immersing, solvent is more easily immersed in the material, accelerates the saponin leaching velocity.
3, extraction solvent temperature of the present invention is 40-50 ℃, and the change of soaking temperature can have influence on the partition equilibrium of tea saponin at solid-liquid, because solvent extraction saponin and water specific rate are very fast, if improve solvent temperature, can quicken the dissolution rate of saponin.What have in the former technology does not heat, and the artificial leaching velocity that improves of great majority heats solvent temperature to more than 50 ℃.Do not heat or temperature to cross low leaching velocity slow, it is too high to heat, the saponin leaching velocity is accelerated, the pigment leaching velocity is accelerated simultaneously.And energy consumption is big, and the loss of solvent is also big.The present invention compares with former technology, and tea dregs of rice slag color is dark after separating, and also darker than the tea dregs of rice color of not extracting tea saponin, this illustrates that most of pigment remains in the slag.Energy-conservation, joint consumption that the present invention compares with former technology has increased one deck guarantee for reducing follow-up decolouring step simultaneously.
4, the production technique that the present invention's employing is flatted turn or pot group type combines.Leaching number of times is 2-3 time, and soak time 1-1.5h compares with former technology 2h-4h, improves work efficiency more than 1 times.
