New Zealand: milk bottles are labeled with RFID tags

saitl dairy laboratory is a professional milk quality testing company in New Zealand that conducts biological and chemical tests on milk. The company now uses RFID technology to automatically identify a high number of milk sample bottles, so as to improve the speed and accuracy of identification, minimize manual processing, reduce errors and improve traceability

Margaret Malloch, general manager of the company, said that the laboratory receives up to 20000 - 30000 plastic round bottles from the dairy factory every day. But the previous recognition system using bar code and manual detection can no longer meet saitl's needs. She said that it is too time-consuming and error prone

we plan to realize laboratory automation, and RFID is a part of it. To this end, we set up a project to study the best scheme for implementing RFID system and the changes required, Malloch explained

at the beginning of 2009, saitl gradually launched RFID applications, including providing labeled sample bottles to several sample collection stations within a few months. During the manufacturing process, a Ti laundry transmitter ds105 13.56 MHz passive RFID tag is pasted on the bottom of each bottle. The bottles were then sent to dairy factories across New Zealand to collect milk samples. The samples were later gathered and sent to saitl's laboratory by Fonterra, a dairy producer. Fonterra owns 11000 dairy farms and is also one of the shareholders of saitl. During the launch of the project, barcode labels were also pasted on the bottles to double check the correctness of the information written on the labels. When the system is officially enabled, the barcode label will be removed from the bottle

the laboratory is a very challenging RFID application environment. Due to the extremely close spacing of samples and the high metal content of many detection instruments, saitl spent a lot of time debugging rfid antennas and readers to ensure the accuracy and accuracy of reading. Another challenge is that the new tags lack a visually readable interface. The barcode labels used by the company in the past include naked eye readable text. However, if the passive 13.56 MHz RFID label replaces the barcode and pastes it on the bottom of each bottle, it may be difficult for skilled workers to locate and identify a specific sample

this requires the use of a customized large antenna and reader software to read multiple tags in a short time, Malloch said

in saitl laboratory, the staff first put the bottle filled with cow fire resistance and burn through resistance milk on the tray, and then moved the tray through a group of RFID readers, a total of three rows, each row has 10 readers. A single tray can hold 250 bottles, and 30 readers can quickly read bottle labels, which comply with ISO 15693 standard and can store 250 bytes of data. The tag data is then sent to the saitl database, and the data return letter details that each sample must undergo a specific test. This ensures that the staff carry out correct biological and chemical tests on each sample, and also ensures the quality and safety of dairy products sold by fon and Terra to customers. Multiple RFID readers and readers are used in many applications of saitl laboratory. Most readers are customized by tracent to solve saitl specific problems. The laboratory staff also used the existing tracer handheld reader on the market to manually read some bottle labels

fonterra installed this system for saitl and has also participated in the milk collection program of work project, of which satl project is a part. In January, 2006, Fonterra milk supply officially launched mcpow, which uses RFID to track the milk collection from the farm to the factory. When Fonterra collects the milk stored in barrels on the farm, the RFID reader on the milk tanker automatically reads the information of each barrel's RFID tag. The construction of T copper based new material industrial agglomeration development base for each barrel has been steadily promoted. I ds105 RFID tag includes company ID code, farm ID code, milk temperature, collection dose, collection time and status code

in saitl applications, a special RFID antenna is connected to the tracer reader to send information to the central database through mobile data transmission or standard synchronization tools. Tracer also customizes the reader for the special environment of the laboratory. Saitl management data software madcap is provided by Contec group

the readers used in the milk collection program of work project include handheld machines, milk tanker and laboratory readers, with a total number of thousands. In Fonterra factories across New Zealand, more than 14000 milk storage VATS have also been labeled, which means that the company can use label information to trace the source of milk samples, the amount collected, and the temperature at the time of collection. The total number of labels used in this project is more than 600000

the ultimate goal of saitl project is to realize a complete RFID milk collection chain: milk samples are labeled, collected from dairy farms to factory storage, and then to saitl laboratory to realize the whole process monitoring and information traceability

she added that for those customers who still use bar codes, we use both bar codes and RFID tags. Once the test is completed, the label identification information is eliminated, the label is removed from the sample bottle, and the bottle is returned to the plastic manufacturer for reuse. Each label can be used 100000 times

sample bottle recycling is an additional income of saitl and one of the benefits of RFID project. Previously, the sample bottle was made of two different plastics, which is impractical to recycle, but the new bottle of milk collection can be recycled. According to Malloch, RFID accelerates sample processing. For example, a single RFID reader can handle 150 bottles. RFID also improves the accuracy of sample identification, determines which samples need to be tested, improves productivity and reduces costs
