Embodiment Construction
[0024] The Thermal Analog Probe (TMP) for the product described may consist of a critical mass temperature sensitive material, usually enclosed within an insulating layer along with standard temperature sensing devices (e.g. thermistors, thermocouples, thermometers, etc.) , can be used to simulate the internal temperature of a box of actual food such as lettuce or other refrigerated or frozen food. The foods include, but are not limited to, French fries, chicken nuggets, orange juice, fresh chicken, fish, eggs, meat, and other perishable foods. The TMP example described below is used to simulate lettuce, however, other food and perishable products can be simulated as required.
[0025] Depending on the type of lettuce (whole, shredded, mixed, etc.) the TMP unit can change size and shape to more precisely track the type of food. One or more thermal probes can be inserted into the TMP to collect the temperature of the TMP. The thermal probe can be wired or wirelessly connected...

Abstract
A method and system for mimicking a thermal profile of a perishable product by fabricating a thermal mimicking probe (TMP). The TMP is obtained by forming a non-perishable, substantially solid material into a predetermined mass or shape, wherein the non-perishable material, in combination with the predetermined mass or size, has a temperature retention property similar to a perishable product; sealing an entirety of the formed material with a protective covering to form a core; accommodating a temperature sensor into a sensor side of the core; forming a first insulating layer on the sensor side of the core; and forming an enclosure of a second insulating layer that covers remaining sides of the core, wherein the first insulating layer is configured as a lid to the enclosure, wherein a change in temperature of a neighboring perishable product is substantially mimicked by readings from a temperature sensor in the core.
Description
[0001] Cross References to Related Applications [0002] This application claims priority to US Application No. 61 / 509,029, filed July 18, 2011, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a food temperature simulation system in the food storage and transportation industry. In particular, it relates to a portable food simulator suitable for replicating the temperature characteristics of a specific food. Background technique [0004] With growing health and liability concerns in the food service industry about contaminated or spoiled food, as well as shortened shelf life and reduced quality, restaurants, grocery stores and food transporters are looking for sophisticated systems to monitor and control refrigerated food . Typical such systems include tracking the temperature of the ambient air within the refrigeration unit and issuing an alarm if the temperature rises above acceptable levels. Ho...
