Description
Technical field
The invention belongs to Microwave Extraction fields, and in particular to a kind of on-line monitoring Microwave Extraction device.
Background technique
Microwave Extraction is a kind of fast and effective means that chemical substance extracts in plant, animal product, the technology
Relevant apparatus is widely used in multiple fields such as food, chemistry, medicine.Ultraviolet-uisible spectrophotometer is a kind of more low
Method that is honest and clean and easily carrying out qualitative and quantitative analysis to bioactive substance, is also widely applied to food, chemistry, medicine etc.
Field.Since ultraviolet-uisible spectrophotometer is needed using deuterium lamp and tungsten lamp, the service life of both lamps is short, needs often to tie up
Shield, and xenon lamp is as its long working life of the light source of ultraviolet-visible, maintenance needs are low, are highly suitable for the environment of rather harsh
Under work long hours.
Now in plant and animal tissue extraction, common operation is empirically using corresponding extracting method, such as
Soxhlet extraction, organic solvent extraction, Microwave Extraction etc. wait the regular hour, then collect product.And these operating parameters are all
It empirically carries out, often occurs excessively extracting, waste time and the energy, too long extraction time also can be to part chemistry
The higher extraction object of activity damages.Soxhlet extraction is relatively fewer using quantity of solvent, and extraction time is longer；Organic solvent
Extraction time is long, low efficiency, and solvent usage amount is larger；Microwave Extraction speed is fast, high-efficient, but it is needed in a relative closure
Environment carry out, be difficult effectively judge extract state and effect, general extraction time will than actual needs the time it is longer,
Guarantee extraction effect with this, and waste mass energy in this way, while it is rotten to will cause part chemically reactive substance.
Summary of the invention
For the deficiencies in the prior art, in order to possess dynamical extraction effect simultaneously, while energy wave is reduced
Take the loss with active chemical components in extract, the present invention provides a kind of on-line monitoring Microwave Extraction device, and the device is effective
Extract concentrations variation in extraction process is monitored, so that control device extraction time, improves extraction efficiency, reduces energy wave
Take, reduces the loss of effective chemical active ingredient.
In order to achieve the above-mentioned object of the invention, the invention adopts the following technical scheme:
A kind of on-line monitoring Microwave Extraction device, including the Microwave Extraction room, flow detection pond and circulating pump being sequentially connected；
The Microwave Extraction room includes microwave generator and extraction lumen；The flow detection pond is that a termination extracts another termination of lumen
Circulating pump.
Preferably, there is xenon source module in the external top in the flow detection pond, and lower section sets spectral detection module.
It preferably, further include control system and touch screen, the control system receives the control instruction that touch screen receives, supervises simultaneously
Control the detection signal that spectral detection module obtains.
Preferably, the flow detection pond passes through return pipe respectively and is connected with Microwave Extraction room and circulating pump.
Preferably, the xenon source module grating belt.
Compared with prior art, the invention has the following advantages:
Extract concentrations change in the device effective monitoring extraction process provided by the invention, thus when control device extracts
Between, extraction efficiency is improved, energy waste is reduced, reduces the loss of effective chemical active ingredient.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of on-line monitoring Microwave Extraction device of the invention；
Description of symbols: lumen 4, return pipe 5, xenon lamp are extracted in circulating pump 1, flow detection pond 2, Microwave Extraction room 3
Source module 6, spectral detection module 7.
Specific embodiment
Below by specific embodiment, invention is further described in detail.But those skilled in the art will manage
Solution, the following example is merely to illustrate the present invention, and should not be taken as limiting the scope of the invention.Specific skill is not specified in embodiment
Art or condition person, described technology or conditions carry out to specifications according to the literature in the art.Agents useful for same or device
Production firm person is not specified, being can be with conventional products that are commercially available.
Embodiment 1
A kind of on-line monitoring Microwave Extraction device, including the Microwave Extraction room 3, flow detection pond 2 and circulation being sequentially connected
Pump 1；The Microwave Extraction room 3 includes microwave generator and extraction lumen 4；The flow detection pond 2 is that a termination extracts lumen 4
Another termination circulating pump 1.
There is xenon source module 6 in the external top in the flow detection pond 2, and lower section sets spectral detection module 7.
It further include control system and touch screen, the control system receives the control instruction that touch screen receives, while monitoring spectrum
The detection signal that detection module 7 obtains.
The flow detection pond 2 is connected by return pipe 5 with Microwave Extraction room 3 and circulating pump 1 respectively.
7 grating belt of xenon source module.
In use, device is switched on, the wavelength for extracting analyte detection is set by touch screen, or directly selects and mention in control system
The active chemical taken, the spectral wavelength of system Auto-matching detection, opens microwave office, and sample is added and solvent, click are opened
Begin.Device starts to preheat, and preheating is completed to automatically begin to work, when spectral detection to signal reaches the spectrum of setting value or setting
The constant duration of signal, device close microwave, stop extracting, while auditory tone cues extraction finishes.
The above is only preferred embodiments of the present invention, is not intended to limit the scope of the present invention,
Therefore any trickle amendment, equivalent variations and modification made to the above embodiment according to the technical essence of the invention, belong to
In the range of technical solution of the present invention.
