In recent years, food safety time has occurred frequently, which not only caused huge economic losses, but also seriously endangered people’s health. Enterprises and regulatory authorities have increasingly higher requirements for food traceability. The food traceability system represented by RFID technology designed by Tianjin Bee has better solved this problem.
One RFID food traceability application background
In the production of the modern food industry, the final link from production to sales has undergone processing, transportation, and storage. A loophole in any link may indicate that the food is in an unsafe state. The RFID food traceability system can provide products for end consumers. Security reports, dealers provide effective supply information recommendations, and manufacturers provide dealer analysis reports. Because RFID radio frequency identification technology is a non-contact automatic identification technology, combined with effective database systems and network systems, it can achieve a global scale The video tracking and information query service withinRFIDFood traceability technology does not require manual intervention, has low requirements on the application environment, data can be encrypted, and stored information can be changed, so it can bring essential changes to the food traceability industry.
Two RFID food traceability system design process
Take the traceability of agricultural products and food as an example:
1 Farm management
For this batch of agricultural products, a series of information from fertilizer, to growers, pickers, etc. are recorded through electronic tagsRFIDThe food traceability system is recorded in the food safety database as raw data.
2 Processing plant management
A series of information such as the manufacturer’s receipt of this batch of agricultural products, storage time, processing time, operator, and processing method are also recorded in the electronic label
3 Transportation process management
In the circulation process, a variety of sensors and reading and writing equipment are arranged in the transportation vehicle or storage container to record the environmental information of the batch of food in real time. The RFID reader installed on the vehicle will read the vehicle at regular intervals. The electronic label information of the food inside, together with the RFID sensor information, is sent to the RFID food traceability system.
4 Warehouse Information Management
When the food is transported to the logistics warehouse, the RFID reader installed in the warehouse will record the warehousing information in detail. At the same time, it will read the label information and record the environmental information at a certain time interval and send it to the food traceability system.
5 RFID warehouse management
Based on the recorded environmental information, the new RFID food quality assessment system will play an unparalleled role, relying on past data to determine expired foods, determine the order of delivery, and estimate that foods that may appear mildew and other conditions provide a data basis for managers . Judging based on environmental information will change the traditional “first in, first out” warehouse management rule, and more effectively and more targeted the delivery management of food in the warehouse.
6 Terminal sales management
Once the food has deteriorated, the evaluation system will also change the evaluation results in real time, prompting retailers to remove the products from the shelves in time.
Through the previous series of management methods, consumers can easily check the origin, producer, and date of production of the products they purchase. At the same time, they can also certify the food according to the evaluation system to enjoy “rest assured food”.
7 Food traceability function
In the event of an emergency, the final consumer of each piece of food can be found based on the RFID food traceability system, and problems in the circulation or production process can also be inquired. This is also the development trend of the international food traceability system.
3. Application status of RFID food traceability system
At present, the domestic food traceability system uses bar code management more. This is mainly due to the fact that RFID technology is not very commonly used in food traceability systems. There are many factors such as cost and lack of understanding. Little bee believes that RFID technology is widely used The day of the food traceability system will finally come, and we are willing to work hard to improve the domestic food traceability situation and contribute to national food safety.
