Description

A near-infrared high-throughput non-destructive selection platform device

technical field

The utility model relates to the technical field of non-destructive detection of crops, in particular to a near-infrared high-throughput non-destructive selection platform device.

Background technique

High throughput screening (HTS) technology refers to the experimental method based on the molecular level and the cellular level, using the microplate form as the experimental tool carrier, using the automated operating system to execute the experimental process, and using sensitive and rapid detection instruments to collect The experimental result data is analyzed and processed by computer, tens of millions of samples are detected at the same time, and the corresponding database is used to support the operation of the technical system. It has the characteristics of trace, fast, sensitive and accurate.

Nondestructive Determination Technologies (NDT for short) is an emerging comprehensive application discipline, which utilizes the heat, sound, and light caused by the abnormal internal structure of the sample or the existence of defects on the premise of not destroying or damaging the object to be tested. , electric, magnetic and other changes to detect its internal and surface defects, and make judgments and evaluations on the type, nature, quantity, shape, position, size, distribution and changes of defects. According to the different non-destructive testing principles, the testing methods can be roughly divided into optical characteristic analysis method, acoustic characteristic analysis method, machine vision technology detection method, electrical characteristic analysis method, nuclear magnetic resonance detection technology and X-ray detection technology, etc.

The near-infrared spectroscopy technology in the optical characteristic analysis method can perform non-destructive analysis on the sample, and has the characteristics of non-contact, non-destructive, high detection sensitivity, short time, small amount of sample required and no need for sample preparation. During the analysis process It will not cause chemical, mechanical, photochemical and thermal decomposition of the sample, which is one of the research hotspots in the field of analytical science.

At present, the technology for non-destructive high-throughput detection at the single-grain level includes a photoelectric color sorting device based on the photoelectric principle to sort the color difference on the surface of a single grain, and has been successfully applied to rice and tea selection. The photoelectric color sorter uses the optical and colorimetric properties of the material to non-destructively detect defective products and sundries with abnormal colors or surface defects from a large number of bulk sample materials, and automatically sort and reject them. , which comprehensively applies new technologies such as electronics and biology, and is a typical high-tech equipment integrating light, machinery and electricity. Since the photoelectric color sorter sorts by color, it can greatly improve the quality of materials, so the unique role of adapting to the commodity market will be very obvious.

However, so far, high-throughput screening methods are difficult to achieve non-destructive detection of crop seeds, etc., and near-infrared non-destructive detection technology has not been well applied in high-throughput screening. The photoelectric color sorting device based on the photoelectric principle to sort the color difference of the single grain surface is limited to the materials with obvious color difference such as rice and tea.
