Nondestructive testing system for viscoelasticity of livestock and poultry meat

Abstract

The invention relates to the technical field of food detection, and in particular relates to a nondestructive testing system for viscoelasticity of livestock and poultry meat. The system comprises an air source device, a control device, a laser position finder and a computer, wherein the air source device is used for outputting airflow to the surface of a to-be-tested sample through a gas pipeline; the control device comprises a single chip microcomputer and a plurality of valve bodies which are connected with the single chip microcomputer; the valve bodies are arranged on the gas pipeline; the laser position finder is connected with a sensing head; the sensing head is used for collecting displacement information of the surface of the to-be-tested sample and feeding back to the single chip microcomputer; and the computer is connected with the single chip microcomputer, and is used for processing and analyzing the displacement information. According to the nondestructive testing system, noncontact action force is formed on the surface of the to-be-tested sample through the air source device; the action time of the airflow and control on air pressure are achieved by the single chip microcomputer and the plurality of valve bodies; airflow pulse is effectively combined with a laser range finding technology, so that the action of nondestructive testing of the viscoelasticity of the livestock and poultry meat is achieved.

Description

technical field [0001] The invention relates to the technical field of food detection, in particular to a viscoelasticity nondestructive detection system for livestock and poultry meat, in particular to a viscoelasticity nondestructive detection system for livestock and poultry meat based on airflow pulse and laser ranging technology. Background technique [0002] At present, the consumption of livestock and poultry meat in my country is increasing year by year. Improving the quality and processing of livestock and poultry meat products to ensure their safety and nutritional value is a major issue related to people's livelihood. Livestock and poultry meat is rich in protein, and the protein and its hydration layer form a network structure, which has a certain ability to resist external forces. This resistance is manifested as the viscoelasticity of meat. [0003] When testing the viscoelasticity of livestock and poultry meat, it is necessary to ensure that the sample is non-...
