HEAT RETAINING CAPACITIES OF INSULATED JUGS

Abstract : There is need for special facilities for furnishing front line troops and casualties with hot food, since, in many cases, kitchen units have not been able to catch up with advance troops until late at night, if at all. This need applied especially to winter operations but exists also when only moderately low temperatures are encountered. The most feasible method for motorized troops is to carry the hot food with them in insulated containers. Vacuum jugs, while extremely effective, are too fragile for practical use. Other means of insulation are available, however, which will provide sturdy containers for the purpose. An 18-quart jug with a new improved insulating material was made available for testing. The results of tests on this jug are given.
