Raw fresh meat non-destructive inspection device

Abstract

The invention provides a raw fresh meat non-destructive inspection device which is characterized by comprising a light source, a light source controller, a filter, a charge coupled device (CCD) industrial camera, a singlechip, a power supply converter, a shading cover and a protecting cover, wherein the protecting cover is positioned above the shading cover; the light source controller, the filter, the CCD industrial camera, a transitional table, the singlechip and a power supply controller are fixed in the protecting cover; the light source is fixed above the shading cover; a lens of the industrial camera is positioned right above the light source; the filter is positioned on the lens of the industrial camera; and a meat sample is positioned in the shading cover. According to the technical scheme, the CCD camera acquires an image of a beef or port sample or a body detection part, so that contactless real-time detection is realized, and grade judgment for main quality of raw fresh meat is realized. Damage to the meat sample is avoided; the detection device is low in cost and precise and stable in detection performance.

Description

technical field [0001] The invention relates to the fields of non-destructive testing technology and image processing technology, in particular to a portable non-destructive testing device for main quality testing of fresh meat. Background technique [0002] With the increasing awareness of food safety and nutritional value, testing institutions, production enterprises, sales markets and consumers have put forward higher requirements for the rapid evaluation of meat quality. As a big country in the production and consumption of agricultural and livestock products, my country's post-production processing level of agricultural products is too low due to backward grading equipment and technology, resulting in uneven quality of meat products in my country and lack of market competitiveness. At present, domestic slaughter enterprises mainly use the following methods to evaluate meat quality: [0003] (1) The traditional physical and chemical testing method, through the sampling ...

AI Technical Summary

Problems solved by technology

[0003] (1) The traditional physical and chemical testing method, through the sampling method, pre-treats the samples to be tested, and realizes it by chemical methods. This method takes a long time to detect and the process is cumbersome, which not only causes waste of samples, but also wastes labor, and also requires evaluation personnel. have professional knowledge

[0004] (2) The sensory evaluation method is completed by specially trained graders using visual senses or referring to the national standard grade chart. This method is labor-intensive, and the classification accuracy is affected by human subjective factors, which often leads to low classification accuracy of samples
