Description
Technical field
The utility model belongs to fruit quality and examines field, is related to the detection of food, especially a kind of fruit quality synthesis
Detection analysis instrument.
Background technology
The present most of functions of fruit quality analytical instrument are relatively simple.Such as：Test the hardometer of fruit hardness
The hardness of fruit can only be individually tested, saccharometer is only capable of the sugar content of test fruit, and gold mark instrument is only capable of test fruit pesticide residue
Situation and spectrophotometer are only capable of content micro- in measurement fruit.These instruments be all each independent instrument, it is necessary to
These individually operated instruments, this needs to take much room and connects many attaching plugs etc..Neither one is comprehensive currently on the market
The instrument of conjunction property measurement fruit quality.
The universal method of inspection of instrument of split type measurement fruit quality currently on the market falls behind, and testing accuracy is poor, operation
Inconvenience, the processing artifical influence factor of data are big.For example fruit hardometer is mostly hand sclerometer, the hand-held fruit hardometer
Operation principle be：Hand-held handle is connected on sensor stand, and foil gauge is adhered on sensor stand, fruit pressure test head
Fixed on sensor stand, fruit pressure test head is passing to power on the fruit fixed to rack.When the opposite force of fruit
Transmit on sensor stand, cause sensor stand to deform, on deformation conduction foil gauge, cause foil gauge resistance to change
Become, the curent change of foil gauge passed through by detection, it is possible to inverse goes out the size of applying power on fruit pressure test head, except
Fruit hardness can be obtained by with the contact area of measuring head 5 and fruit.The method for expressing of the hardness of general fruit be kg/
Square centimeter or pound/square inch.The Handheld fruit hardometer has the disadvantage that：1. using hand-held fruit Durometer measurements
When fruit hardness, influenced by artificial factor it is bigger, such as says different hand-held method, insertion angle difference of pressure test head and
Insertion speed is not that at the uniform velocity etc., error is bigger when causing the same sample repeatedly to measure, it is difficult to judge the accurate hardness of fruit.
2. foil gauge is manually to be attached to glue on sensor stand, the asymmetry that foil gauge is puted up is likely to result in deformation and electricity
The change of stream is not linear relationship；If system compensation parameter setting is not right, it is easy to produces the result that pressure test is not allowed.Strain
The piece load-carrying ability that withstands shocks is limited, is only 3~5 times of dynamometry limit of power, holds the scleroscopic once casual cunning of fruit
Fall will result in the irreversible damage of foil gauge.Foil gauge service life is limited, generally not over 5000 times, with test
Number increases, and foil gauge moves closer to fatigue limit, and the glue for being bonded foil gauge is also easily subject to the influence of environment and occurs
Change, or even foil gauge obscission occurs.
Above-mentioned reason causes Handheld fruit hardometer can only be as a kind of subtest means of hardness measurement, Wu Fazuo
For the standard approach or method of fruit hardness measurement, can not also promote the use of on a large scale.
What another kind was universal during fruit gold mark check meter uses instrument, is mostly worked using CCD13 Image Acquisition modes, its
Structure is the groove for having in colloidal gold card a bar shaped mostly, and golden target test strips are placed in groove, after adding measuring samples
It can change colour on golden target test strips T line (detection line) and C lines (nature controlling line), prepare liquid can be judged according to the depth of color
Yin and yang attribute.Ccd image collection gold mark instrument has the disadvantage that：1st, according to the gray value judgement sample of the CCD13 images collected
It is negative or positive.The gray value of CCD13 images is influenced greatly by ordinary light source, and the emergent light circular illumination of ordinary light source not only can
It is irradiated on the T lines (detection line) or C lines (nature controlling line) in colloidal gold card detect tank, can be also irradiated on gold mark bracket shell, gold
Gray value influence of the mark bracket shell reflected light on ccd image is bigger, this make it that the gray value of ccd image is locally unstable,
Cause feminine gender and the positive judgement of sample inaccurate, especially more easily determine mistake in weakly positive or weak negative sample.2nd, at present
CCD gold mark check meter detection poor repeatabilities, can only do some and qualitatively detect, or the detection of sxemiquantitative, it is impossible to do quantitative inspection
Survey, that is, be only able to detect and whether there is a certain material, but cannot detect the content of this material is how many.
Consideration of the spectrophotometer underlying instrument based on cost of fruit context of detection, the light of spectrophotometer are used at present
Road part is essentially all that LED monochromatic light does light source simple light path system, the monochromatic light that monochromatic LED light source is sent, by be checked
After test sample sheet, photoelectric sensor is arrived at.Since the sample to be tested of various concentrations is different to monochromatic trap, according to monochrome
The difference of the degree of absorption of light come judge detect sample concentration.The wide half-wave of monochromatic LED light source is usually 15~20nm, it is difficult to
Find the LED of uniform fixed wave length；In addition also there is a light decay in LED, with adding for monochromatic LED light source usage time
Long, the brightness of monochromatic LED light source is that darkness deepens, and light intensity is more and more weaker, it is necessary to be carried out every time before inspection using titer
Correction.LED spectrophotometers detection optical wavelength is unstable, wavelength is not allowed, detects light intensity change greatly, these can all cause to detect
Result error is very big, seriously affects the testing result of fruit quality.The monochromatic LED light source of LED light source spectrophotometer is due to knot
The limitation of structure generally can only at most provide the monochromatic LED light source of 4 wavelength, and cannot at will replace the ripple of monochromatic LED light source
It is long.
The saccharometer for being used for sugar degree detection on the market is hand-held estimation mode mostly.Horizontal light source is solid by one
Determine slit and enter liquid to be checked, it is different according to the concentration of inspection liquid sugar, reflect that the yawing moment of light is also different, in liquid to be checked
Another side has one with graduated transparency glass plate, by the incident light that detects by an unaided eye in the position of transparency glass plate not
Together, it is possible to read inspection liquid pol.Need to calibrate before each detection, when detection is manually operated relatively more, man's activity
Factor is relatively more, the poor repeatability of pol value, it is also necessary to which artificial record detects data every time；The service life of instrument is short, generally
Service life is 1000 times or so.
By the retrieval of patent document, related patent document is not yet found.
