Description
Technical field
The present invention relates to a kind of from lacquer tree fruit lacquer seed extract the method for lacquer tree fat.
Technical background
Lacquer tree is one of important traditional economy woods of China, and cultivation history is long, and variety source is abundant.Lacquer tree not only secretes raw lacquer, and the fruit of lacquer tree-lacquer seed contains abundant grease, and crude fat content reaches 45-55%.Lacquer seed size is approximate with soya bean, annual gathering in 9-10 month in autumn.The lacquer seed divides 3 layers, and exocarp layer and middle pulp layer are wax layer, can extract lacquer tree fat, and kernel is seed, can squeeze sumac seed oil.Lacquer tree fat is the dystectic solid fat of vegetalitas, and main component is the higher fatty acid TG, and wherein palmitic acid content reaches about 70%, is to produce the natural industrial chemicals of product high-quality such as tensio-active agent and washing composition.
For many years, the extraction of China's lacquer tree fat mainly is local method and solvent extration.Local method namely is China lacquer tree place of production masses coat with lacquer seed with the squeezing machine squeezing a kind of extracting method.Local method is because production technique falls behind, and extraction yield is low, and method is coarse, and impurity and the moisture content of gained waxy stone are higher, and color and luster is dark and impure, and saponification value is low, and acid number is higher, and greatly impact is sold.Solvent extration namely is to dissolve a kind of method of then filtering and producing with the wax that solvent will coat with lacquer in the seed.The method complex process particularly can be used normal hexane or petroleum naphtha equal solvent in extraction process, the loss phenomenon can more or less occur in the production process, thereby polluted air worsens production environment.
Summary of the invention
The purpose of this invention is to provide a kind of technique simple, extraction yield is high, does not need to use chemical solvents in the technique leaching process, is conducive to coat with lacquer the environmental protection extracting method of lacquer tree fat of the industrialized utilization of seed.
Technical scheme of the present invention may further comprise the steps
1), with dry after the fresh lacquer seed screening impurity elimination, drying temperature is no more than 60 ℃;
2), the lacquer seed that drying is good is pulverized not being higher than under 20 ℃ the condition;
3), the lacquer powder of seeds after will pulverizing is at water soaking, is separated into the lacquer seed kernel that is sunken to water-bed layer after the stirring, and the lacquer seed skin and the pulp that float on section waterborne;
4), after lacquer seed skin that separation is obtained and pulp removes surface water, boiling between 50-55 ℃;
5), with well-done lacquer seed skin and pulp by squeezing, obtain lacquer tree fat solution and in water, process through the ultrasonic stirring decolouring, obtain the lacquer tree fat solution of processing through decolouring behind the Separation of Water.
Described cooking time is controlled at 30-40min.Preferably be controlled at 30-35min.
Described lacquer seed skin and pulp are removed surface water and are finished by centrifugation.
Squeeze pressure is 5-6Mpa.
The preferred drying temperature of the present invention is 10-60 ℃.Described drying can adopt the form of natural air drying.
Of the present invention 2) preferably will coat with lacquer seed in the step pulverizes under 3～20 ℃ condition.
Of the present invention 1) fresh lacquer seed should be dried to moisture content and is lower than 8% in the step.
Described decolouring is out the cured solution of lacquer of squeezing is pumped into and adds water decolorization in the bleacher and process; Temperature should be controlled at 70～80 ℃, with agitator stir on one side, impact with ultrasonic wave on one side.The preferred stirring velocity of the present invention is 50-60rpm.In addition, ultrasonic power and calibration are respectively under the condition of 400W and 47.6kHz and process 60-70min.
The lacquer tree fat that the inventive method is extracted is faint yellow or oyster white.
The invention has the advantages that:
(1) the invention provides a kind of cured extracting method of lacquer of environmental protection, without chemical solvents,, such as the normal hexane in the extraction process or petroleum naphtha equal solvent.In addition, the present invention has avoided the pollution to environment without diatomite or carclazyte decolouring;
(2) working method of the present invention is simple, is convenient to suitability for industrialized production;
(3) method of the present invention has improved the extraction yield of lacquer seed; And not only outward appearance is good for the lacquer tree fat of method preparation of the present invention, and the yield of lacquer tree fat is high, reaches 40%-45%.
Description of drawings
Accompanying drawing 1 is the concrete process flow sheet of the present invention.
Embodiment
Following examples are intended to illustrate the rapid steel invention, rather than limitation of the invention further.
The concrete technical process of the present invention is referring to Fig. 1.
Embodiment
1. screening impurity elimination, drying
Select fresh lacquer seed without disease and pest, remove the inclusion-frees such as branch and leaf, then clean with flushing with clean water.To coat with lacquer seed after draining away the water and place under the sun and dry, can't be dry with the temperature that surpasses 60 ℃.Fresh lacquer seed should be dried to moisture content and be lower than 8%, otherwise easily goes mouldy, and is difficult to ensure and deposits.
2. pulverize
Select dry good one-tenth lacquer seed, then pulverize not being higher than under 20 ℃ the condition.Pulverizer fragment rotating speed is pulverized under the 1500-2000rpm condition.Product sieves with 20-30 purpose screen cloth.Can't pulverize in summer, because summer temp is high, adds and pulverize the heat energy that produces, may cause the wax dissolving, thereby not reach the effect of separation.
3. the seed skin separates
Powder after the pulverizing of lacquer seed is put into water soak, use simultaneously agitator stir about 30min.Bottom lacquer seed kernel sinks owing to density is high, coat with lacquer seed skin and pulp density little and float on top.Collect at bottom of gullet and the water surface respectively, thereby reach the purpose of separation.
4. dehydration
Lacquer seed skin and be stained with more moisture after the pulp water separates, then be the centrifugal 1min of separating centrifuge of 3000rpm with speed, the moisture that removal is surperficial too much.
5. boiling
Lacquer seed skin after the dehydration and pulp place boiling in the steam cooker, and boiling temperature is controlled between 50-55 ℃, and the time is between the 30-35min.
6. squeezing
After well-done lacquer seed skin and pulp taken out from steam cooker, be put in the squeezing machine rapidly and squeeze.Squeeze pressure is 5-6Mpa.
7. decolouring
Squeezing lacquer tree fat solution out should pump into rapidly decolouring in the bleacher.Inject approximately 1/4 water in the bleacher, temperature should be controlled at about 75 ℃, with agitator stir on one side, impact with ultrasonic wave on one side.Stirring velocity is 50-60rpm, and ultrasonic power and frequency are respectively under the condition of 400W and 47.6kHz and process 60-70min.Then, the water of bottom is emitted, on can obtain lacquer tree fat solution.
8. heating casting
Be that lacquer tree fat solution about 75 ℃ pumps into it rapidly moulding in the corresponding model with pump with temperature, finish product approval.Compare with the lacquer tree fat of solvent extration preparation with local method, not only outward appearance is good for the lacquer tree fat of this law preparation, and the yield of lacquer tree fat is high, reaches 40%-45%, its physical and chemical indexes such as table 1.
The physical and chemical indexes of table 1 lacquer tree fat
