Description

A kind of acidity of fruit confection quality real-time detection apparatus
Technical field
The present invention relates to a kind of detection means, more particularly to a kind of acidity of fruit confection quality real-time detection apparatus.
Background technology
Fruit because the several mineral materials containing needed by human body, vitamins and other nutritious components and by people as indispensable daily consumption product, with the improvement of living standards, people there has also been requirement higher to the good mouthfeel of sugariness of edible fruits.Traditional detection technique is not only wasted time and energy, but also fruit can be damaged.In recent years, the fast development of Near Infrared Spectroscopy Detection Technology makes it possible to realize quick, the Non-Destructive Testing to fruit drops concentration using near-infrared spectral analysis technology.The features such as Near Infrared Spectroscopy Detection Technology has fast and convenient, lossless, accurate, is used widely in agricultural and food service industry.
Domestic and international researcher has achieved great achievement using near-infrared (NIR) analytical technology to fruit internal quality Indexs measure, Kawano selects 680 ~ 1235nm spectral region near infrared spectrums, and the sugared concentration of oranges and tangerines is tested and analyzed using the method for transmission;Slaughter has carried out quantitative study using near-infrared spectral analysis technology to the index such as soluble solid content, pol and chlorophyll A content in nectarine;McGlone have studied influence of the different near infrared detection systems to the apple internal sugar Concentration Testing of high-speed motion.At home, although research of the near-infrared spectral analysis technology in agricultural byproducts starts to walk than later, considerable achievement has also been achieved.The influence that grandson leads to etc. using near infrared spectrum combination visible ray to the soluble solid content of Nanfeng orange is studied;The influence using near-infrared diffusing reflection technology to apple fructose concentration such as Liu Yande has carried out quantitative study;The influence using near-infrared diffusing reflection technology combination wavelet compression techniques to farina content such as Dong little Ling has made intensive studies;Sea otter high etc. realizes the discriminating to fresh dates kind and the Weeding to bad jujube using near-infrared diffusing reflection spectrum.Forefathers are proved by substantial amounts of experiment, realize that to the detection of fruit drops concentration and acidity be feasible indirectly using near-infrared diffusing reflection technology, substantial amounts of experience is have accumulated in this respect, but most of researchs only reside within experiment level, the design studies scheme of the acidity of fruit confection real-time detection also without complete set.
The content of the invention
Detection the invention aims to realize sugar degree and acidity inside quality, devises a kind of acidity of fruit confection quality real-time detection apparatus.
The technical solution adopted for the present invention to solve the technical problems is:
Acidity of fruit confection quality real-time detection apparatus are made up of the part such as transmission unit, control unit, spectra collection unit and data processing unit.
The described transmission unit part such as including pallet, track, transport trolley.During designed path, actual size according to fruit and realize fruit smooth transport requirement, track is formed using the shape extrusion of in the market, designed using 2 parallel angle iron formed steel constructions, ensure the parallel of 2 angle bar, the angle of angle bar provides guide effect for dolly, it is ensured that the oriented motion of dolly.
Described control unit detects that transmitting apparatus and component communication interface for required control on testing stand are constituted by 1 pair, is responsible for the action of control dolly, completes the work such as fruit positioning, spectra collection.
The described spectra collection unit part such as including acquisition probe, optical fiber, spectrometer is constituted, and is responsible for completing the task to the spectra collection of each fruit.
Described data processing unit is first pre-processed using the method for polynary scattered color correction (MSC) to the diffusing reflection spectrum of fruit, remove noise wave removing, then acidity of fruit confection forecast model is set up using PLS (PLS), completes the prediction to acidity of fruit confection.
The beneficial effects of the invention are as follows:
This research carries out global design to acidity of fruit confection near infrared detection system first, detailed design explanation mainly has been carried out to transport module, lighting module, spectra collection module and data analysis and processing module, test result indicate that realize that to the detection of acidity of fruit confection be feasible indirectly using near infrared spectrum diffusing reflection technology, and with preferable effect.With the acidity of fruit confection modelling effect set up after Pretreated spectra more preferably, wherein, the preprocessing procedures using polynary scattered color correction (MSC) are optimal to the model of foundation after Pretreated spectra.
