X-ray-imaging-based citrus dry water floating skin detection device and method

Abstract

The invention provides an X-ray-imaging-based citrus dry water floating skin detection device and method. The X-ray-imaging-based citrus dry water floating skin detection device comprises a material conveying module, feedback modules, an imaging module, a radiation protection module and a control system; the material conveying module is used for conveying citrus materials, the imaging module is installed on a rack of the material conveying module, and the radiation protection module is installed on the imaging module; the feedback modules are installed at an inlet and an outlet of the imaging module, the control system controls the imaging module to emit X-rays and collect X-ray images of citrus materials according to position information, detected by the feedback modules, of the citrus materials at the inlet, and the imaging module transmits the X-ray images of the citrus materials to the control system. The control system controls the imaging module to stop emitting the X-rays according to the position information, detected by the feedback module, of the citrus materials at the outlet; the control system processes and analyzes the collected citrus images and judges the conditions of dry water and floating peel of the citrus according to the X-ray images of the citrus materials, so that the internal quality of the citrus is judged.

Description

technical field [0001] The invention belongs to the technical field of non-destructive testing, and in particular relates to an X-ray imaging-based detection device and method for citrus dry water floating skin to detect the internal quality of citrus. Background technique [0002] Post-harvest citrus commercial treatment technology is backward, which can easily lead to uneven quality, dry water, floating skin and other quality problems, which affect the quality of citrus. Traditional methods usually use sampling methods to conduct destructive tests, which cannot fully detect internal quality. Therefore, the development is based on non-destructive The citrus internal quality detection method of detection technology just seems particularly urgent. [0003] After searching, there is currently no literature report on the detection of dry water and floating skin inside citrus based on non-destructive testing technology. The invention patent with the publication number CN10477712...

[0002] Post-harvest citrus commercial treatment technology is backward, which can easily lead to uneven quality, dry water, floating skin and other quality problems, which affect the quality of citrus. Traditional methods usually use sampling methods to conduct destructive tests, which cannot fully detect internal quality. Therefore, the development is based on non-destructive The citrus internal quality detection method of detection technology is particularly urgent

[0003] After searching, there is currently no literature report on the detection of dry water and floating skin inside citrus based on non-destructive testing technology. The invention patent with the publication number CN104777129A discloses an online detection device for the internal quality of citrus fruits based on visible and near-infrared spectroscopy. Obtain the sugar content of citrus, obtain the spectral information of citrus through spectral detection, and then fuse the two information to form an effective internal quality detection model of citrus, so as to realize the online non-destructive detection of internal quality of citrus; the invention patent with the publication number CN104849321A discloses A method for rapid detection of citrus quality based on olfactory fingerprints. The random forest model is used to establish a quantitative prediction model for the olfactory fingerprint information of the electronic nose sensor and the vitamin C, total acid, and total sugar in the citrus juice to predict the citrus juice to be tested. Vitamin C, total acid, and total sugar; but these methods can only detect the physical and chemical quality of citrus, and cannot detect defects such as dry water and floating skin of citrus
