Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, the flow process of the technical solution of the present invention is: first, the fresh jujube is transported to the rotating device B station by the mechanical conveying device A, and under the action of the rotating device B, the fresh jujube has realized a 360 ° rotation, and the fresh jujube is at the same time The position information of the workstation is collected by the visible-near-infrared spectrum acquisition device C, and then the visible-near-infrared spectrum acquisition device C collects the visible-near-infrared spectrum information of fresh jujube, and compares the collected spectral information with the fresh jujube with or without slight damage discrimination model, Extract the discriminative information of slightly damaged fresh jujubes and intact fresh jujubes. When the fresh jujubes are transported to the D area ...

Abstract

The invention discloses an on-line rapid non-destructive detection and sorting device for slightly damaged fresh dates. The device comprises a mechanical conveying device, a rotation device, a visible near-infrared spectrum acquisition device and a sorting device, wherein the mechanical conveying device is used for conveying fresh dates to a transmission roller at the station of the visible near-infrared spectrum acquisition device; the rotation device is used for enabling the roller to drive the fresh dates to rotate for 360 degrees; the position information of the fresh dates is judged through a sensor; the position information is transmitted to a micro optical fiber spectrometer through an optical fiber; the acquired spectrum information is transmitted to a model for judging whether the fresh dates are slightly damaged or not in computer system software; a signal that whether the fresh dates are slightly damaged is transmitted to a PLC (programmable logic controller) through the software in a computer; an electromagnetic control valve and a whole sorting execution mechanism which is connected with an air compressor are controlled by the PLC, and thus automatic sorting on slightly damaged fresh dates and complete fresh dates is achieved. By adopting the device, rapid, non-destructive, dynamic and real-time detection and sorting on slightly damaged fresh dates can be achieved.

Description

technical field [0001] The invention relates to the technical field of detection and sorting of fresh jujube quality, in particular to a fast and non-destructive on-line detection and sorting device for slightly damaged fresh jujubes using visible and near-infrared spectroscopy technology. Background technique [0002] Fresh jujube is crisp in texture, sweet in taste and unique in flavor. It is not only a nutritious food, but also a natural health care product, and is favored by consumers. In recent years, with the development of science and technology and the improvement of fresh-keeping technology, the supply period of fresh jujube has been extended, the economic benefits have doubled, the added value after harvest has been greatly improved, and the income of farmers has been increased. Many areas have given priority to the development of fresh jujube industry in the adjustment of agricultural industry structure, and the cultivated area and output are increasing rapidly. ...
