Self-heating lunch box / food processing

Self-heating lunch box
Self-heating lunch box

In poor and war-torn places, and in the posts of lower classes of cities, it is difficult for people to eat hot food. For the self-heating lunch box with natural light as the source energy, the food in the container is heated based on the principle of collecting heat for a convex lens. In heating, you only need to adjust the bracket to find the right light angle. The whole lunch box is made of heat- resistant PP plastic materials, which are economical, practical and cheap. While it can maximize the quality of life of the people from the lower class, it also reduces the occurrence of gastrointestinal diseases.
