Considering room pressure and temperature, things are not cooling at their fastest possible rate. Blackbody radiation isn't the only way things cool down. You are forgetting conduction and convection. Liquid nitrogen can cool things down super quickly.

I'm not forgetting them: they're just but relevant to the way I interpreted the question. I'm assuming OP wants something that works on a similar physical principle to a microwave, not just a fast way to chill things.

Ah sure, yeah, if they want it to actually use radiation, it's not possible.
