Description
Technical field
The present invention relates to agricultural byproducts processing technical field, specially a kind of method of ultrasonic wave assisted extraction tung oil.
Background technique
Tung oil tree is the distinctive commodity trees in China, is distributed mainly on southern region of China, and tung oil is extracted from bancoul nuts
Grease, be a kind of natural vegetable oil, composition is mainly fatty acid triglycercide mixture, and detectable fatty acid has
It is 9 kinds, main to have 5 kinds, i.e. palmitinic acid, stearic acid, oleic acid, linolenic acid and eleostearic acid, wherein again with tung oil acid content highest, about
It is 80 percent, tung oil has the characteristics that rapid drying, high temperature resistant, corrosion-resistant, and tung oil also has good waterproofness, is system
The primary raw material of paint, ink is made, the production of waterproof, anti-corrosion, rush-resisting material is largely used as, and oilcloth, oilpaper, fertilizer can be made
Soap, pesticide and pharmaceutical nauseant, agrochemical, tung oil can also be used to produce biodiesel, increasingly be expected to rise in energy prices
There to be vast potential for future development using reproducible tung oil resource production biodiesel today；
In the prior art, tung oil tree seed generally mentions oil process using traditional compacting and organic solvent extraction carries out tung oil extraction
It takes, compacting mentions oil process when extracting tung oil, needs to heat tung oil tree seed, generally requires temperature being promoted to 100-150 and take the photograph
Family name's degree, when carrying out extraction to tung oil tree seed and mentioning oil, polymerization work easily occurs for three conjugated double bonds in tung oil main component eleostearic acid
With, and people contains grease about 6 percent to 10 in remaining tung oil tree oil meal, and is easy to cause work in summer

With the development of science and technology, ultrasonic technology gradually uses in all trades and professions, and ultrasonic wave has wavelength
Short and beam by force and is easy to concentrate mentioning a little for energy by focusing, thus its effect between coal quality can be divided into calorifics mechanism,
Mechanics of Machinery mechanism and three kinds of cavitation mechanism, from multi-expert to ultrasonic wave assisted extraction grease the experimental results showed that, mentioning oil
Under conditions of rate is essentially identical, ultrasonic wave assisted extraction can reduce Extracting temperature, shorten extraction time, save solvent usage,
But also the quality of grease can be improved, but existing compacting mentions oil process and organic solvent extraction when extracting tung oil, exists
It is toxic, not environmentally, it is of poor quality and mention the disadvantages of speed oil is slow, solvent consumption is big, and there is the tung oil quality irregularity extracted, it is former
Expect that oil yield is low, the big phenomenon of material loss is easy to cause tung oil tree seed material loss excessive, reduces the fuel-displaced of tung oil tree seed
Rate, the quality irregularity of tung oil, is not available, thus benefit when influencing plant produced tung oil.
Summary of the invention
The present invention provides a kind of method of ultrasonic wave assisted extraction tung oil, can effectively solve to propose in above-mentioned background technique
There are it is toxic, not environmentally, it is of poor quality and mention the disadvantages of speed oil is slow, solvent consumption is big, and there is the tung oil quality extracted not
Rule are closed, raw material oil yield is low, and the big phenomenon of material loss is easy to cause tung oil tree seed material loss excessive, reduces tung oil tree kind
The oil yield of seed, the quality irregularity of tung oil, is not available, thus benefit when influencing plant produced tung oil etc. ask
