Successful cases of RFID hanging lines used in slaughterhouses

In recent years, various meat food safety problems have frequently occurred in various countries around the world, such as mad cow disease, avian influenza, antibiotic residues, illegal addition of hormones, etc., which have seriously affected human health. Meat food safety problems have become increasingly serious and have become a serious concern for agricultural and health departments around the world. important task of supervision.

Our country is a major livestock producer in the world, but its share of the world's meat export market is very low. The important reason is the lack of food safety guarantee. The root cause of meat food safety problems is that meat products often change the properties of raw materials in the supply chain, making it difficult to identify the quality of raw materials from finished products. In addition, multi-level processing and circulation links have an impact on product quality and safety.

This case is a technical solution for informatization and traceability management of the pig slaughtering process based on RFID technology. Based on the project business needs, the equipment selection and deployment requirements for RFID application in each link are designed, and a set of slaughtering systems can be established in the pig slaughtering enterprise. The information collection system realizes the information management of the entire process from purchase and admission, resting supervision, pre-slaughter quarantine, slaughtering and processing, simultaneous quarantine, sales settlement, and logistics distribution.

System workflow

1. Before slaughtering, pigs must first go through handover, quarantine and resting with upstream breeding enterprises. We become acquisition resting. The main processes include: completing the formulation of acquisition plan, registration of entry quarantine information, registration of weighing information, first Recording of settlement information, management of resting time, registration of patrol shed quarantine information, and drafting of pig slaughter notices.

2. Entering the slaughtering process, the routine workflow of slaughtering and processing:

After the hanging, ironing, shaving or peeling is completed, during the renovation and lifting process, an RFID Reader, track scale and industrial tally machine are installed next to the track. The track scale and RFID reader are connected to the industrial tally machine through the serial port, and are pre-installed on the hook. After using the RFID tag, the RFID reader reads the hook RFID information and transmits it to the industrial tally machine. At the same time, the weight of the pig collected by the track scale is also transmitted to the tally machine, and the binding and information registration work is completed on the tally machine interface.

After the whole pig has its head and feet cut off, the red and white offal (by-product outsourcing) and split into halves, it must undergo post-slaughter quarantine and rating. An RFID reader and industrial tally machine are also installed here to read the RFID tag information and record the hooked halves. Pig quarantine results and grades.

Qualified pigs enter the laser engraving process, and quarantine qualification information and traceability information must be engraved on the pig skin. Then enter the wholesale transaction link.
