Shipment Temperature Monitoring for Milk Crate Transport

eTradeWire News/10539439
CLEVELAND - eTradeWire -- CAS DataLoggers provided the shipment temperature monitoring solution for a milk supply company. During deliveries to distant receivers, including farmers' markets and supermarket chains, the milk's temperature needs to remain at a constant 2-3°C (36-37°F) throughout transit. Naturally, milk is an extremely temperature-sensitive product, which begins to spoil if its temperature changes more than a few degrees, curdling at the bottom of the jug. If this occurs, the milk will be returned by receivers as unsafe for sale due to health risks and is thrown out.

Now, the milk company uses I-Plug Temperature Data Loggers in the back of their trailers to closely monitor milk temperature. Drivers enclose the loggers into their self-adhesive pouches and place them directly onto the crates, four per truck. Their lightweight and compact design make for an easy fit among the gallon containers. Installed this way, the temperature data loggers provide good coverage of the shipment and continually monitor the product throughout transit.

The data loggers start up with the push of a button and also have a stop button which sets them to bookmark readings but keep monitoring until reaching the end of their journey. Users set the sampling frequency to take a product reading once every 15 minutes, and it only takes 90 seconds for the sensor to register an alarm. The data loggers turn on on their alarm LEDs when they take a sample and find that the product is outside the safe temperature range set before the trip. Drivers simply check the loggers during routine stops and look at the status lights indicating that temperatures are OK, Over, or Under.

When delivering the crates to receivers, drivers use each data logger to transfer its temperature data via the USB port to a PC allowing a pdf report to be printed directly. The free software download for I-Plug data loggers also sends their temperature data online to a database where receivers can view it in graph format, in this case using the driver's Android tablet with a free app.

The milk company saves both time and product by using the portable I-Plug loggers in the back of their milk trucks, which provide effective and reliable monitoring for their temperature-sensitive product during transit. With this simple solution, it's much less common for drivers to find spoiled product. The ability of the I-Plug logger to provide an immediate printed .pdf report allows the producer to comply with FDA regulations and satisfy the customer that they are getting a safe product.
