In-transit temperature recorder helps dairy processor monitor milk deliveries
The milk supplier began looking for accurate temperature monitoring devices featuring customizable alarm levels that would safeguard their product’s freshness by alerting personnel when temperatures were about to go out of specification.
CAS DataLoggers, Chesterland, Ohio, supplied an in-transit temperature recorder solution for a large milk supplier in the United States.
During frequent deliveries to far-off receivers such as regional markets and supermarket chains, milk temperature needed to be maintained at a constant 2°-3°C (36°-37°F) throughout the trip--otherwise the product would be returned by receivers as unsafe for sale. These transports were often sent out to remote destinations where proprietary software and interfaces were unavailable, and the average fresh milk delivery took 3-5 days to reach store shelves. Being an extremely temperature-sensitive product, the milk would spoil if its temperature varied too much. Harmful bacteria started to form whenever the shipments suffered a slight heat increase and then a rapid decrease, causing spoiling and curdling at the bottom of the gallon jugs. At that point, the milk had to be written off as a loss to the company.
