In transport of fresh food, a monitor of container is indispensable. We propose two methods for non-destructive measurement of temperature in the container. In the first method, additional walls are joined to the container, and the temperature of the container is passively estimated by extrapolating the temperatures in the additional walls. In the second method, a Peltier cooler is joined to the additional walls, and the temperature of is actively measured by flattening the gradient of temperature in the additional walls. We demonstrate that the temperature in a styrene foam is estimated within error margin ±1 ℃ under the good condition. Furthermore, we compare the experiment results with numerical results by ANSYS to consider the forecast model.
