A kind of on-line monitoring Microwave Extraction device
Technical field
The utility model belongs to Microwave Extraction field, 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.
Utility model content
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 utility model provides a kind of on-line monitoring Microwave Extraction device, the device
Extract concentrations change in effective monitoring extraction process, so that control device extraction time, improves extraction efficiency, reduce energy
Source waste, reduces the loss of effective chemical active ingredient.
In order to realize above-mentioned purpose of utility model, the utility model uses 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 utility model has the following beneficial effects:
Extract concentrations change in the device effective monitoring extraction process provided by the utility model, so that control device mentions
The time is taken, extraction efficiency is improved, reduces energy waste, reduces the loss of effective chemical active ingredient.

Specific embodiment
The utility model is described in further detail below by specific embodiment.But those skilled in the art will
Understand, the following example is merely to illustrate the utility model, and should not be regarded as limiting the scope of the utility model.In embodiment not
Particular technique or condition person are indicated, described technology or conditions carry out to specifications according to the literature in the art.It is used
Production firm person is not specified in reagent or device, and 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 the utility model preferred embodiment, is not made to the technical scope of the utility model
Any restrictions, thus it is all according to the technical essence of the utility model any trickle amendment made to the above embodiment, equivalent change
Change and modify, is all within the scope of the technical scheme of the utility model.
