A near-infrared non-destructive detection device for sugar content of fruits with adjustable illumination parameters

Abstract

A near-infrared fruit sugar degree nondestructive detecting device with adjustable illumination parameters comprises two parts, namely a spectrum collecting module and a data processing and operating interface module, wherein the spectrum collecting module mainly realizes the adjustment of light source irradiation parameters and the function of collecting sample spectral information; the data processing and operating interface module mainly realizes the reading, saving, displaying and transforming of the spectral information, the parameter setting, the prediction of fruit sample sugar degree, and the displaying function. According to the invention, the irradiation angle of the light source can be adjusted, or the position of the light source in a sliding chute of a lamp bracket can be changed, so as to achieve the purposes that different parts of fruits, fruits with different sizes and different kinds of fruits are detected; the position of the lamp bracket in the V-shaped bracket sliding chute can be changed to change the intensity of the light source irradiating on the fruits, so that fruits with different peel thicknesses and different sizes can be detected.

Description

technical field [0001] The invention discloses a near-infrared fruit sugar content non-destructive detection device with adjustable illumination parameters, which belongs to the technical field of non-destructive detection of agricultural products by using near-infrared spectrum. Background technique [0002] With the continuous improvement of living standards, consumers not only pay attention to external qualities such as size, color and shape, but also put forward higher requirements for internal qualities such as taste, sugar content and acidity when purchasing fruits. At present, for the detection of the internal quality of fruits, most of them adopt the methods of artificial sensory evaluation and conventional chemical analysis. The artificial sensory evaluation method has the disadvantages of strong subjectivity and different evaluation standards; as for the conventional chemical analysis method, although it has the advantages of high detection accuracy and strong accu...

Problems solved by technology

Most of the above-mentioned near-infrared spectrum detection instruments or devices have a fixed irradiation angle and irradiation distance of the light source. Sometimes when other detection objects are to be detected, the irradiation angle and irradiation distance of the light source need to be reset.
