How do you know if your waffles are really frozen?
Kellogg’s created an ingenious solution to monitor the cold chain process of their Eggo® frozen waffles. At the manufacturing site, a special model c\temp dsc (-40C) was placed into selected boxes of the waffles with a recording duration of 180 days. Each box that contained the c\temp had instructions on returning the unit back to Kellogg’s for a cash rebate as well as coupons for other Kellogg’s products. Upon receipt of the c\temps, temperature profiles were created that were analyzed to show the shipping temperatures from manufacturing site to warehouse to supermarket to customer. Return of the units averaged over 90%. Quality was assured.
