Plastic food containers with integral heating devices will be available for sale in large supermarkets in the coming months. This food packaging container was developed by Steam To Go of Bruton, manufactured by Dragon Plastics of Pontypridd. The heat source of this food package comes from the exothermic reaction of water and quick lime. By pressing the button, the water reacts with the quicklime and the reaction heat can produce temperatures of up to 300 °C. The resulting steam flow enters the food compartment through a series of small holes and the steam flow is precooked in approximately 4 minutes. The food is reheated. Steam To Go emphasizes the benefits of cooking methods, paying particular attention to the potential product range of rice, pasta, and noodles that are more suitable for heating with steam than microwave or oven heating.
çƒ The heat engine for self-heating food packaging is now injection molded from polypropylene, but it is also tested with nylon 66. The final choice of raw materials for the production of the heat engine is still in progress before the trial sale of the product. The self-heating type food container is injection molded with linear low density polyethylene, and the reaction manipulator is injection molded with high density polyethylene.
