Embodiment Construction

[0038] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0039] like Figure 1-4As shown, a device for improving the sorting accuracy of moldy apples includes a moldy apple detection device. The moldy apple detection device includes a halogen light source 100, a bifurcated optical fiber probe, a lens 120, an apple support table 130, an optical fiber, and a spectrometer 150. One side of the apple supporting table 130 is provided with a halogen light source 100, and a lens 120 is provided between the halogen light source 100 and the apple supporting table 130;

Abstract

The invention discloses a method and device for improving the sorting precision of inner-moldy apples, and is used for solving the problems of invalid detection caused by unfixed detection areas of existing apple sorting devices and damage to apples due to excessively-high power of infrared light sources. Through arrangement of a bifurcated optical fiber, the detectable areas of the optical fiberare increased, so that the area, deviating from the centers of the apples, of inner mold can be detected; meanwhile, after the bifurcated optical fiber is used, the intensity of spectral signals received by a spectrograph is greatly improved, so that the power of an infrared light source can be reduced, and damage to the apples can be reduced; through arrangement of a transverse roller and a vertical roller, the apples can rotate in a groove of a correction table, then the postures of the apples are adjusted, the detectable area of the optical fiber is the surfaces of the apples rather than the concave areas on the two sides of the apple center shaft tire bases, and then the problem of invalid detection due to the fact that the detection areas are not fixed is solved.

Description

technical field [0001] The invention belongs to the field of sorting, relates to apple sorting technology, and specifically relates to a method and a device for improving the sorting accuracy of inner mold apples. Background technique [0002] Apple moldy heart disease, also known as heart rot, is one of the main apple diseases in my country. The ventricle of the affected fruit is moldy or rotten, causing problems such as fruit drop during the growth period, reduced quality of mature fruit, and fruit rot during storage. Apples with moldy heart will not only bring economic losses to fruit farmers, but also affect the health of consumers. [0003] Near-infrared spectroscopy is an effective method for detecting the internal quality and surface damage of apples. It has the advantages of fast detection speed, no damage to apples, low cost, and no chemical reagents. Therefore, near-infrared spectroscopy is more and more suitable for Fruit quality inspection. The fruit and vegeta...
