With the rapid development of society, prepared dishes are becoming more and more popular among consumers because of their convenience. However, despite the advances in prepared food technology, fluctuating prices of ingredients, food safety issues, and limitations in its production and distribution are all challenges facing the industry.
RFID technology not only has identification capabilities, but will also enhance sensing capabilities in the future. These tags will not only report their identity, but will also be able to transmit information such as temperature and humidity, thus making things smarter and more connected. This technology has a real demand in the field of health care, cold chain logistics and so on.
RFID (Radio Frequency Identification) is a non-contact automatic identification technology. It can work in a variety of harsh environments and can quickly recognize multiple tags.RFID systems are mainly composed of tags, readers and antennas. In order to better utilize the advantages of RFID technology in cold chain logistics, the technology nowadays has integrated temperature sensors into RFID tags to achieve real-time temperature monitoring.
Another significant advantage of RFID technology is its read-write capability. When goods enter a warehouse, an electronic tag can be attached to the package or pallet and information about the goods can be written to the tag. Through RFID readers, companies can monitor the situation of goods in the warehouse in real time, as well as the temperature in the refrigerated truck during transportation to ensure the quality of food.
RFID temperature tags have replaced traditional barcodes in the transportation chain. These tags not only work continuously for a long time, but can also be reused. In order to monitor the temperature in real time, refrigerated trucks need to be equipped with RFID readers and wireless communication devices. In this way, managers can receive real-time temperature information and deal with possible abnormalities in a timely manner, thus reducing losses.
In the storage segment of refrigerated logistics, RFID technology also shows its unique advantages. The traditional way of checking goods often requires manual counting one by one, but the use of RFID technology can automatically and quickly complete the count. In addition, RFID technology can also monitor the temperature of the cold storage in real time to ensure the quality of goods.
Raw materials are transported from the cold storage to the processing workshop according to the production demand. The reader antenna at the entrance of the cold storage warehouse automatically records all outgoing behaviors and proofreads them against the outgoing tasks, saving time and improving efficiency. At the front of the conveyor belt, the reader reads the RFID code of the raw material and obtains a unique code number to associate with the subsequent processed product. The finished product is stored and associated with the raw material to ensure traceability, before being transported to the cold store for sale.
