The method has the advantages of simplicity, convenient operation, short extraction time, high extraction rate, low acid value of the extracted coffee oil, good oil quality, no heating, less energy consumption and environmental protection.
Description
Technical field:
The invention belongs to Vegetable oil lipoprotein extractive technique field, particularly relate to one utilize ultrasound wave from
The method extracting coffee bean oil. in coffee grounds.
Background technology:
Coffee is one of big beverage in the world three, in the international market, based on the accumulative trade amount of money,
Coffee is only second to oil and occupy second.In coffee product, instant coffee owing to quoting conveniently,
Meet modern society's rhythm, increasingly welcome by people.According to statistics, the consumption of instant coffee
The 20% of Liang Yizhan world coffee consumption, almost the coffee grounds of 50% is to process instant coffee
During coffee produce, in coffee grounds containing about 20% oils and fats, 10% protein, 58% carbon aquation
Compound and abundant mannan are (after acid hydrolysis, containing 15%-30% in its hydrolyzed solution
D-MANNOSE) and the composition such as galactose, coffee grounds is its warm when for combustion of industrial boiler
Value about 5000 kilocalories/kilogram, this is that other agro-industry garbages are unrivaled, 2008
There is scholar to attempt using coffee grounds to extract coffee bean oil. in year, and use transesterification process mode by coffee
Oil is converted into biodiesel, and this process can produce the biodiesel of 10%-15%, and its yield takes
Certainly in the kind of coffee；Scholar within 2010, is had to use the coffee bean oil. extracted from coffee grounds equally
Doing raw material, use enzyme catalysis transform mode to produce diesel oil, conversion ratio is up to 98.5%, from coffee
It is more stable for obtaining biodiesel in slag, does not changes under the observation more than month.Mesh
The plan of the front biodiesel extracting 3.4 hundred million gallons from coffee grounds has been started up, and extracts oils and fats
After coffee grounds be preferable garden fertilizer, ethanol raw material and burning particles, additionally coffee bean oil. is
A kind of valuable spice oil, can be used as the odorant of food, it may also be used for manufacture through dilution
The perfume etc. of coffee odor type.But, not yet utilize ultrasound wave to extract coffee bean oil. from coffee grounds
Pertinent literature or the open report of technique or use.
Ultrasonic extraction principle ultrasound wave is propagated in medium and medium particle can be made to propagate sky at it
The interior vibrational state that enters, strengthening solutes accumulation, mass transfer, i.e. ultrasound wave mechanism.Ultrasound wave exists
In medium particle communication process, its energy is constantly absorbed by medium particle and becomes heat energy, causes medium
Particle temperature raises, i.e. ultrasound wave calorifics mechanism, simultaneously when substantial amounts of ul-trasonic irradiation is in extraction
Medium, when vibration is in diluted state, medium is torn into many little holes, these apertures
Cave moment closes, and produces the instantaneous pressure of up to several kilo-atmospheric pressures, i.e. cavitation phenomenon during Guan Bi.
Owing to the residing Extraction medium such as the thing that is broken containing substantial amounts of dissolved gas in ultrasonic field
And small impurity, they are enclosed in the colloid periadventitial of the thing etc. that is broken, make for ultrasound wave
With providing essential condition, the enormous pressure produced in air causes the thing cell wall and whole of being broken
Individual organism ruptures, and whole rupture process completed in moment, and what ultrasound wave produced simultaneously shakes
Action release and the dissolving strengthening intracellular organic matter.Ultrasonic disruption process is a physics mistake
Journey, without chemical reaction in leaching process, the bioactive substance being leached keeps at short notice
Constant, biological activity does not subtracts, and improves broken speed simultaneously, shortens the broken time, can pole
Big raising extraction efficiency.And, ultrasound wave is elastic mechanical vibration wave, is beyond audition valve
Sonic vibration, excusing from death wave energy produce and transmit powerful energy, give medium particle with big speed
Degree and acceleration, acceleration increases along with increasing of frequency of sound wave, and ultrasound wave is at Cucumber
In, can be more deeper than what some electromagnetic waves penetrated, the time of staying is the most longer, again due to big energy
Ul-trasonic irradiation in liquid, when vibration is in diluted state, liquid can be torn into perhaps
The least hole, these foveolas the most i.e. close, and produce and be up to several kilo-atmospheric pressures during Guan Bi
Instantaneous pressure, becomes cavitation phenomenon.These cavitation phenomenons can refine various material and manufacture
Emulsion, accelerates the effective ingredient in plant and enters solvent so that it is extract further, to increase
The extraction rate of effective ingredient.In addition to cavitation, many second order effects of ultrasound wave, such as machine
Tool vibrates, emulsifying, diffusion, smashes, and it is effective that chemical effect etc. is the most all conducive to making in plant
Composition shifts, and fully mixes with solvent, promotes the carrying out extracted.
Summary of the invention:
It is an object of the invention to the shortcoming overcoming prior art to exist, seeking design provides one
