Grading system and method for fruit internal quality inspection

Abstract

The invention, which relates to the technical field of agricultural machinery, provides a grading system and method for detecting the internal quality of fruits. The grading system for detecting the internal quality of fruits comprises a fruit conveying line for conveying independent fruit supports, a quality detection mechanism for collecting near infrared spectra of the fruits located on the independent fruit supports, a plurality of fruit unloading mechanisms sequentially arranged in the conveying direction of the independent fruit supports, a quality judgment mechanism and a PLC. The quality judgment mechanism acquires a quality grading result based on the near infrared spectrum and a preset model, and associates the quality grading result with an independent fruit support number sentby the PLC to acquire quality detection information; and the PLC controls the corresponding action of each fruit unloading mechanism based on the independent fruit support number and the quality detection information. With the grading system, rapid and automatic detection of the internal quality of fruits, especially thin-skin fruits can be realized, and the problem that fruit damage is easily caused in fruit quality detection is solved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a grading system and method for detecting the internal quality of fruits. Background technique [0002] Post-harvest fruit commercialization is an important means to improve product competitiveness and product value. Through commercialization, the commercial value of fruits can be greatly improved. In terms of fruit quality, whether in the international market or the domestic market, consumers not only pay attention to external qualities such as size, color and appearance shape, but also pay more attention to internal qualities such as sugar content and acidity when purchasing fruits. [0003] The internal quality grading of fruits has always been a key step in the postharvest commercialization of agricultural products. Proper internal quality grading can not only prolong the storage period of products, but more importantly, it can increase the market competitivene...
