Stray light control device of fruit spectral separation production line for sugar degree and acidity inside fruit

Abstract

The invention provides a stray light control device of a fruit spectral separation production line for the sugar degree and acidity inside a fruit. The device comprises a lifting fruit tray, and an arched supporting plate capable of making the position of the fruit tray to be continuously lifted. Accordingly, a stray light control method that a detecting section conveying line moves along an arc and the position of the fruit tray is continuously lifted is achieved, the arched supporting plate matched with a fruit cup is additionally arranged on a detecting section conveying line, and stray light control is achieved through the arched supporting plate to reduce the influence of stray light on a detecting system. On the premise of not transforming the production line, the precision of dynamic detection and separation on the internal quality of the fruit is improved.

Description

technical field [0001] The invention relates to a stray light control device for a fruit internal sugar acidity spectrum sorting production line, and belongs to the technical field of online nondestructive detection of agricultural and forestry fruits. Background technique [0002] With the continuous improvement of people's living standards, consumers not only pay attention to external qualities such as size, color and shape, but also pay more attention to internal qualities such as taste, sugar content and acidity when purchasing fruits. At present, the sorting of foreign fruits after picking has begun to develop from external quality inspection to internal and external quality inspection. Near-infrared spectroscopy diagnostic technology is a new technology that can detect the internal quality of fruits without destroying the fruits. The United States, Israel, Japan, New Zealand, Belgium and other countries have put this technology into the post-harvest processing of agric...

AI Technical Summary

Problems solved by technology

[0003] At present, there are certain deficiencies in the near-infrared detection and sorting production lines of fruits at home and abroad. The unreasonable design will easily lead to the inability to fully collect the fruit spectral information, and there will also be problems with stray light, which reduces the operability of the instrument; It will affect the regularity of the target spectrum and reduce the sorting accuracy of the sorting system
