Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, in an embodiment of the present invention, a kind of fast analyser of liquid food ingredient, comprising: light source
1, the light source 1 includes multiple wavelength；Sample cell 2, for placing testing liquid food, light source 1 is connected with sample cell 2 using optical fiber
It connects, the light source 1 emits light into sample cell 2；Fiber optic splitter 3, fiber optic splitter 3 are connect with sample cell 2 using optical fiber, will
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 obtaining not
With the transmitted light of wave band；Multiple photoswitches 5 are separately connected multiple optical filters 4, for controlling the on-off of different channel fibers；Light
Fine 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 close
Beam device 6, the intensity signal exported for detection fiber bundling device 6；Computer 8, connecting detection device 7, for obtaining final inspection
Survey 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 invention is: testing liquid food being placed in sample cell 2, the light that light source 1 issues passes through optical fiber
Inject testing liquid food, after transmitted light enters optical fiber, divide through fiber optic splitter 3 for multichannel, the multi-channel optical fibre separated it is every
Pass through different wave length bandpass filter 4 all the way, other unwanted wavelength can be filtered out, obtain the transmission of wavelengths of interest
Light.Light enters photoswitch 5 by optical fiber, and photoswitch controls the on-off of each road optical fiber, respectively obtains testing liquid food difference wave
Long absorbing state finally converges to an optical fiber by optical-fiber bundling device 6 by the optical fiber of photoswitch, into detector 7；Root
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 testing liquid
Absorption information of the food to different wave length；Finally, passing through the optical signal of 8 acquisition testing device of computer, later data analysis is carried out
With processing, the composition information of testing liquid food is obtained.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
