The utility model has the beneficial effects that the device has quick, free of contamination feature, it is the representative of green test technology,
It is the ideal style to liquid food composition detection with significantly improving analysis efficiency, reducing artificial and production cost potential.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
It is attached that FIG. 1 is a schematic structural view of the utility model.
In figure: 1- light source, 2- sample cell, 3- fiber optic splitter, 4- optical filter, 5- photoswitch, 6- optical-fiber bundling device, 7- inspection

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, in the embodiments of the present invention, a kind of fast analyser of liquid food ingredient, comprising:
Light source 1, the light source 1 include multiple wavelength；Sample cell 2, for placing testing liquid food, light source 1 and sample cell 2 use light
Fibre connection, the light source 1 emit light into sample cell 2；Fiber optic splitter 3, fiber optic splitter 3 are connected with sample cell 2 using optical fiber
It connects, a branch of optical fiber is divided into multi-channel optical fibre；Multiple optical filters 4, are bandpass filter, are connect with fiber optic splitter 3, for
To the transmitted light of different-waveband；Multiple photoswitches 5 are separately connected multiple optical filters 4, for controlling the logical of different channel fibers
It is disconnected；Optical-fiber bundling device 6 connects multiple photoswitches 5, for multi-channel optical fibre to be closed beam to a root multimode fiber；Detector 7, connection
Optical-fiber bundling device 6, the intensity signal exported for detection fiber bundling device 6；Computer 8, connecting detection device 7, for obtaining most
Whole testing result.
Further, the light source 1 used is halogen lamp.
Further, the sample cell 2 used is quartz colorimetric utensil.
The working principle of the utility model is: testing liquid food is placed in sample cell 2, the light that light source 1 issues passes through
Optical fiber injects testing liquid food, after transmitted light enters optical fiber, divides through fiber optic splitter 3 for multichannel, the multi-channel optical fibre separated
Per all the way pass through different wave length bandpass filter 4, other unwanted wavelength can be filtered out, obtain the saturating of wavelengths of interest
Penetrate light.Light enters photoswitch 5 by optical fiber, and photoswitch controls the on-off of each road optical fiber, and it is different to respectively obtain testing liquid food
The absorbing state of wavelength finally converges to an optical fiber by optical-fiber bundling device 6 by the optical fiber of photoswitch, into detector 7；
The on-off of each road optical fiber is controlled according to photoswitch, detector is able to detect that the optical signal of different wave length, and then obtains prepare liquid
Absorption information of the body food to different wave length；Finally, passing through the optical signal of 8 acquisition testing device of computer, later data point is carried out
Analysis and processing, obtain the composition information of testing liquid food.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in
All changes in justice and range are embraced therein.It should not treat any reference in the claims as limiting
Related claim.
