Abstract

The invention discloses an online detecting device for internal quality of orange type fruits based on visible-near infrared spectroscopy. A through groove is horizontally formed in the middle of the bottom of an illumination box, a conveying mechanism penetrates through the bottom of the illumination box, spectrum collecting units are installed on both sides of the center of the bottom of the illumination box, position sensing units are installed on both sides of a conveying inlet of the illumination box, the spectrum collecting units and the position sensing units are installed on both sides of the conveying mechanism at the left and right; a longitudinal fixed rod is installed at the top of the illumination box downwards, an automatic dark field and reference collecting unit is connected to the bottom of the longitudinal fixed rod, and the spectrum collecting units and the position sensing units are connected with an industrial computer through a spectrograph. The online detecting device disclosed by the invention can be used for automatically collecting a dark field and a reference, the components are convenient to adjust, and meanwhile, energy loss can be reduced.

Description

technical field [0001] The invention relates to an agricultural product detection device, in particular to an online detection device for the internal quality (sugar content) of citrus fruits based on visible and near-infrared spectra. Background technique [0002] my country is a big citrus producing country. According to statistics from the International Citrus Society, my country's citrus planting area and output both ranked first in the world in 2007. Citrus is rich in potassium, B vitamins, vitamin C and antioxidant components, anti-cancer components, anti-allergic components, and also rich in flavonoids, polyphenols, carotenoids and other compounds, which have high nutritional value and dietary health effects. However, the internal quality of citrus is difficult to detect in large quantities. At present, destructive testing is usually carried out by sampling; there is also evaluation and grading based on appearance, but this grading method is not accurate. Rapid non-...
