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.
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.
Because of its superior vacuum insulation, Zojirushi food jars have excellent heat retention. With just a few minutes of prep time, foods can complete cooking in the food jar, making prepping lunches in the morning quick and easy.
