Automatic grading system and grading method for degree of chicken breast lignification based on hardness deformation

Abstract

The invention discloses an automatic grading system and a grading method for the degree of the chicken breast lignification based on the hardness deformation. The grading system is composed of a hardware module, a characteristic parameter extraction module, and a lignification grading module; the hardware module comprises a laser jet device controlled by an industrial personal computer, which comprises a trigger sensor, a belt conveyor arrangement device, a laser distance measuring device, an air booster pump, a high pressure air nozzle, fixed brackets, and fixed baffles; the characteristic parameter extraction module extracts five characteristic parameters highly correlated to the chicken breast; and the characteristic parameters obtained by the lignification grading module through a characteristic parameter extraction analysis module are modeled and predicted by a BP neural network model. The grading method determines the degree of the chicken breast lignification according to the characteristic change of the chicken breast before and after high-pressure air injection. According to the automatic grading system and the grading method for the degree of the chicken breast lignification based on the hardness deformation, the online non-destructive rapid detection of the degree of the chicken breast lignification is realized.

Description

technical field [0001] The invention relates to the detection and determination of chicken breast meat quality grades, and belongs to the field of agricultural product processing and detection, in particular to an automatic grading system and grading method for the lignification degree of chicken breast meat based on hardness deformation. Background technique [0002] With the increasing market demand for boneless chicken, poultry farming enterprises are increasingly inclined to breed broiler chickens with high meat yield and fast growth. Today, the age of broiler chickens has been reduced by nearly half compared to 50 years ago, but the live mass of broiler chickens has doubled that of 50 years ago. However, with the popularization and development of fast-growing broiler breeds in the poultry market, a series of broiler breast muscle diseases and quality defects have been exposed one after another. Among them, woody breast meat (Woody Breast, WB) is the most influential on...
