What is vacuum insulation
Vacuum means the air between the outer and inner layers of stainless steel has been removed to create a vacuum insulation. It blocks heat from transferring through air.
The vacuum layer does not have to be thick, as the absence of air is what's important and not the amount. Zojirushi's vacuum insulation is as thin as 1mm, keeping the unit compact and lightweight without compromising temperature retention.
How do Zojirushi food jars keep foods hot (or cold)?
Heat loss happens through 3 methods, and Zojirushi vacuum insulated products use the following methods to block them. Foods stay hot because heat doesn't escape. Foods stay cold because outside heat can't get in.
1. Vacuum insulation blocks heat from transferring through air
Vacuum insulation prevents heat loss through conduction. Since the air– which is a conductor – is removed between the inner and outer layers of stainless steel, heat isn’t transferred.
2. Aluminum or copper foil reflects heat
A thin sheet of aluminum or copper is wrapped around the outer surface of the inner layer to help reflect radiant heat.
3. Lid blocks heat convection
And finally, heat transfer through convection is blocked by an insulated lid.
What is thermal cooking?
Thermal cooking is a method of cooking that uses the food's own heat to complete cooking. The food is heated initially, then placed within an insulator to maintain heat.
