Well, it does exist, it's called laser cooling, but it's only if you want to have things really cold

Flash freezing things is a thing.

Flash freezing is how frozen foods are made.

Probably not. Nice choice of pic to illustrate the need, though 😄

Liquid nitrogen bath, works opposite of a microwave, freezes it from outside and towards the middle.

It's a lot easier to generate heat from electricity than to transfer them out. Closest bet would be just blasting cold air but heat transfer will be slow so it's still quite limited.

You would need to find a way to make food spontaneously emit microwaves so it loses energy and cools off. That probably involves altering the strength of one of the nuclear forces or something.

There is a drink chiller that chills drinks in about a minute. You could use the same idea for other things.

What I would like to know is if we will ever have microwaves that stop the spinning plate in the same place that they started. It's XXI century, I want to take out my cup as easily as I've put it in.
