SELF-HEATING FOOD WARMER 10 PIECES

What is self-heating?

Self-heating is a technology developed for food or beverage which allows you to eat warm meals without recurring to fire or other external heat sources. This active packaging uses a heat releasing chemical reaction to warm up the food inside them to very high temperatures. This means that even if you find yourself inside a snowstorm while hiking a mountain with below-zero temperatures, you’re still going to be able to taste a hot and complete meal.

How do self heating food work?

As the name suggests, self-heating foods require no external heat source for preparation. Heat is generated by an exothermic reaction caused by adding room-temperature water to powdered minerals such as magnesium, iron, calcium oxide and salt. Commercial heat sources for self-heating food packaging use an exothermic (heat releasing) reaction, for which there are several common formulations. These include: Quicklime aka calcium oxide, and water. Quicklime, inexpensive and readily available, is generally recognized by the FDA as safe.

What chemicals are used in self-heating food?

Uniquely, when calcium oxide reacts with water to create calcium hydroxide, the reaction releases a lot of energy in the form of heat. Since it is a non combustible material, the chemical reaction is ideal to heat your beverages inside a self-heating can.

Self-heating food packaging have a heating module inside it which helps to heat the ready to eat food or beverage in it. Exothermic reaction is used as heat source. Such product can be very useful for military operations, during natural calamities, for mountaineers, and whenever conventional cooking is not possible. It also proves useful in daily life as one can get hot food anywhere without need of microwave oven to reheat the packed food.
