Description
[technical field]
The present invention relates to a kind of tea seed deep process technology field, a kind of tea saponin that extracts that is specifically related to from the oil tea tea dregs of rice adopts the concentrated Technology field of membrane sepn.
[background technology]
Tea saponin has another name called the tea saponin; be by a class candy glucoside compound that extracts in the tea tree seed; it is a kind of well behaved natural surface active agent; it can be widely used in fields such as light industry, chemical industry, agricultural chemicals, feed, breed, weaving, oil recovery, mining, building materials and expressway construction, makes emulsifying agent, cleaning agent, inert ingredient, fodder additives, crab shrimp aquaculture protective material, textile auxiliary agent, oilfield foaming agent, mining flotation agent and gas concrete suds-stabilizing agent and concrete admixture---frostproofer etc.
The basic technology of domestic industry proposition tea saponin is as follows at present, at first the tea dregs of rice is pulverized and is ground; Lixiviate in the flat-turn leacher then, adding concentration is 65% methyl alcohol in flat-turn leacher, and the mass ratio of oil tea and methyl alcohol is 1: 10, stirs back about 2.5 hours, the bottom obtains methyl alcohol saponin mixing solutions from flat-turn leacher, extracts the back that finishes and obtain the saponin slag in flat-turn leacher; Methyl alcohol saponin mixing solutions is put into long-tube evaportor reclaim methyl alcohol; After put into external circulation evaporator and reclaim moisture, then spraying drying promptly obtains the tea saponin finished product.
This technology is in the external circulation evaporator stage, reclaim moisture and reach cotton-shaped tea saponin throw out is concentrated purpose, solid content about 30%, spraying drying then.Adopt external circulation evaporator to concentrate, following shortcoming arranged at present:
1. use quantity of steam big.Per hour evaporate 1000 kg of water, basic gas consumption is in 1000 kg of vapor.
2. recovery and concentration time are longer.Per hour to evaporate 1000 kilograms vaporizer is example, needs 6 hours just can reach spissated purpose, is easy to bubble, and causes to turn over pipe and need to evaporate again in condenser.
Since vaporizer in temperature 100 the degree about, 6 hours time caused the material color darker, and the finished product Application Areas is restricted.
Based on the problems referred to above, make its energy consumption in production process height, operation inconvenience, the size variation of quantity of steam often causes foam to turn over pipe, and color is darker, the Application Areas of restriction finished product.
[summary of the invention]
For solving above deficiency, the invention provides a kind of technology that tea saponin adopts membrane sepn to concentrate of extracting, adopt this technology can overcome energy consumption height in the tea saponin extraction process, operation inconvenience, the size variation of quantity of steam often causes foam to turn over pipe, finished product and color are darker, the Application Areas of restriction finished product.
The technical solution used in the present invention is: a kind of tea saponin that extracts adopts concentrated its concrete steps of technology of membrane sepn as follows:
1. tea dregs of rice raw material is adopted drying machine drying, the back is ground into particulate by grinding device grinding;
2. the tea dregs of rice after will pulverizing are put into flat-turn leacher and are added the methyl alcohol lixiviate, extract methyl alcohol saponin mixing solutions in the flat-turn leacher bottom, extract the flat-turn leacher residue that finishes and are the saponin slag;
3. above-mentioned methyl alcohol saponin mixing solutions is put into long-tube evaportor and reclaim methyl alcohol;
4. above-mentioned solution is passed through activated carbon filtration impurity and pigment, reclaim moisture by membrane separation plant then;
5. promptly obtain the finished product tea saponin after above-mentioned crude product being adopted spraying drying.
Described a kind of tea saponin that extracts adopts the concentrated technology of membrane sepn to it is characterized in that the concentration of described methyl alcohol is 50%-80%, and the mass ratio of the methyl alcohol and the tea dregs of rice is 1: 6-1: 12, and methyl alcohol and the tea dregs of rice mixing time 1-3 hour.
Described a kind of tea saponin that extracts adopts the concentrated technology of membrane sepn to it is characterized in that described solution is 10-20 minute by the activated carbon filtration time;
Described a kind of tea saponin that extracts adopts the concentrated technology of membrane sepn to it is characterized in that described membrane separation plant adopts the Chinese medicine membrane separation plant, will pass through the film that does not wait big small-bore, effective filtration area 20-50m through the liquid behind the activated carbon filtration
2, processing power 1T/H;
The present invention is based on above principle and adopt impurity and pigment in the activated carbon filtration solution, make the low increase finished product of colourity of final finished utilize the field.By membrane separation technique, aforesaid liquid is at first equaled the tea saponin molecular diameter by membrane pore size, because the impurity molecule aperture can't pass through greater than this membrane pore size impurity, and tea saponin and water molecules can screen and pass through; Then by membrane pore size less than tea saponin molecule aperture but, effective tea saponin is filtered out, and water molecules reclaims by film greater than the water molecules aperture.Adopt membrane separation technique can tea saponin to separate completely and hold back, water is removed, make effective constituent obtain concentrating refining; And make impurity be not easy to be blocked in the film surface by the operation process of particular design, and having solved a film contamination and plugging difficult problem, the film permeate water can be recycled prerequisite and go out operation, energy-saving and emission-reduction.
Application of membrane separation technology has following advantage in this technology:
1. whenever take off one ton of water, power consumption 5 degree (solid content is concentrated to more than 30% by 2%);
2. normal temperature concentrates down, can not cause saponin liquid to bubble and turn over pipe;
3. product colour is lighter, and Application Areas is wide in range.
Beneficial effect of the present invention: adopt the production technique of this law, can reduce energy consumption in the production process, and various raw materials are recycled, the energy-conservation reduction simultaneously discharged, and improves the quality of products simultaneously.
Further understand feature of the present invention and technology contents for making, see embodiment for details, yet appended embodiment is only for reference and explanation usefulness, and the present invention is limited.
