Problems solved by technology

[0002] Non-destructive testing of fruits usually uses near-infrared spectrum diffuse reflection to detect the sugar content of fruits. Optical fiber detectors usually irradiate the fruit vertically. When the light passes through the fruit, it will also produce reflection phenomenon. Once reflection occurs, the detection results will be affected. How to design a near-infrared detection device that reduces or even avoids the reflection of light after passing through the fruit has become a research topic for those skilled in the art.

Embodiment Construction

[0011] The present invention is described in more detail according to accompanying drawing now, as figure 1 As shown, a near-infrared fruit non-destructive testing device includes a sample holder 2 and an FT-IR spectrometer 8, and the spectrometer 8 includes a light source, a detector, an optical fiber 7 and an optical fiber probe 6, and the light emitted by the light source passes through the incident optical fiber 7 Enter the optical fiber probe 6 to irradiate the fruit surface, and the light reflected from the fruit surface enters the detector through the optical fiber probe 6 and the receiving optical fiber 7 for processing and analysis. The sample holder 2 is a cylindrical frame, and the top of the frame is provided with a fruit surface. Placement platform, the middle part of the fruit placement platform has a through hole for erecting fruit and slightly smaller than the size of the fruit, the bottom of the frame is provided with a turbine screw lifter 1, and the lifting o...

Abstract

The invention provides a near-infrared nondestructive testing device for fruits. The device comprises a sample rack, a light source, a detector, an optical fiber and an optical fiber probe, wherein the sample rack is a columnar frame provided with a fruit placing table on the top; a through hole which is slightly smaller than a fruit is formed in the middle of the fruit placing table; a turbine lead screw lifter is arranged at the bottom of the frame; an optical fiber probe installation frame which is a hollow cylinder matched with the optical fiber probe in shape and with a first through slot on the side face is arranged on a lifting rod of the lifter; the width of the first through slot is greater than the wire diameter of the optical fiber; the optical fiber probe is erected on the top of the cylinder by virtue of a bump on the optical fiber probe; a hollow wedged block with a second through slot on the side face is arranged between the top of the cylinder and the bump; the hollow part of the wedged block is matched with the optical fiber probe in shape. The angle of the optical fiber is changed by way of arranging the wedged block on the optical fiber probe bracket, so that the problem that light is reflected by fruits is solved. The device provided by the invention is simple in structure, strong in practicality, low in cost and high in accuracy.

Description

technical field [0001] The invention belongs to the field of infrared detection equipment, and in particular relates to a near-infrared fruit nondestructive detection device. Background technique [0002] Non-destructive testing of fruits usually uses near-infrared spectrum diffuse reflection to detect the sugar content of fruits. Optical fiber detectors usually irradiate the fruit vertically. When the light is diffusely reflected by the fruit, reflections will also occur. Once reflection occurs, the detection results will be affected. How to design a near-infrared detection device that reduces or even avoids the reflection of light after passing through the fruit has become a research topic for those skilled in the art. Contents of the invention [0003] The problem to be solved by the present invention is to provide a near-infrared fruit non-destructive detection device that reduces the degree of light reflection after passing through the fruit, thereby improving the det...
