Custom Data Logging Protects Milk Production Process

CLEVELAND - March 12, 2021 - PRLog -- Milk Tanker Sanitation Made Easy to Ensure Food Quality

Data retention and accountability are critical for many of the industries we serve. This is especially true for food-grade applications, such as the milk production process. Tanker trucks haul milk from the farm to processing plants on a daily basis. These tankers need to be cleaned and sterilized between deliveries to ensure food safety and quality. As part of the process, a permanent record showing the key information has to be generated.

Sterilization Data Solution

We recently completed a custom data logging system to help ensure that milk tankers reach the proper sterilization temperature for each wash and to provide documentation of the milk production process. Reading and recording temperature data is rather straightforward, it was the accountability side of this project that made it unique.

To measure the temperature, we utilized a standard dataTaker DT82i data logger equipped with a K-type thermocouple probe. This logger features 2 universal analog input channels, allowing measurement of a wide range of sensors and signal types. The logger also features Ethernet and RS-232/RS-485 ports, allowing easy connection to other equipment. The logger was programmed using the dEX graphical software to sample the temperature every 10 seconds and keep a running track of the maximum temperature during each sterilization run. Internal memory for approximately 2 million data points allows it to store data from many days' worth of operation without the risk of losing old data.

Connection to the logger was made via Ethernet using the standard Modbus TCP protocol, which greatly simplified the bi-directional exchange of data between the HMI and the logger. These values are recorded in the data logger along with the temperature data, and they can also be printed out on a receipt-style printer at the end of the cleaning process.


The custom data logging system provided a complete solution to the problem of documenting the cleaning process. A durable temperature probe was quickly inserted into the tank being cleaned. Then, using the touch screen HMI, the operator could enter all of the trailer, seal, and permit info and start the recording process. The current and peak temperature was continuously updated while the process was running. At the end of the run when the cleaning was complete, a receipt-style printout that captured all of the key information could be generated with a single button push. Going forward, there will be no doubt that the wash station has completed its job.
