Taiwan produces an average of 190,000 metric tons of discarded oyster shells per year, of which 26,000 metric tons are unappropriated. In the past, about 70% of discarded oyster shells were used in feed, compost and cultivation media, and their added value was not high.The abandoned oyster shell not only occupies space, low economic value and environmental pollution.With nuclear family, low-birth rate, the fastfood habits of campers, and the aging society in Taiwan who use fire and power often causes fire.This project establishes a suitable oyster shell as a condition for the self-heating source of the food.The spontaneous heat source package of compound F is treated with calcination temperature. After heating, the water temperature can reach 80 °C at 7-8 minutes, and the inner temperature of the squid conditioning package is about 50 °C. It meets the palatability of human oral cavity and esophagus with a maximum tolerance of 50-60 °C. The heating effect is comparable to that of commercially available heating p
