ABSTRACT:
A flameless heater system has at least one tray which is configured to hold a water-actuatable heater pad to produce an exothermic heating reaction for one or more pouches containing food or a beverage and a water supply apparatus associated with the tray. This water supply apparatus is in the form of a trough sized to receive an amount of water sufficient to produce, when applied to the heater pad, adequate to heat contents of the at least one meal pouch and arranged so as to produce the reaction by a slight tilting of the tray without spilling water. The tray is provided with device to securely retain the pouch or pouches and a bottom portion with a raised land portion to receive a complementary lip portion of the heater pad. The water supply apparatus can also be arranged at a side of the tray with a first portion configured to receive a filling tube and a second portion associated with the first portion for metering water into the bottom of the tray. Several trays can be arranged one above the other to heat a variety of foods and/or beverages at the same time.
