There are products such as microwave ovens that can quickly heat food. What I am asking is why are there no products that is opposite of microwave ovens as everyday product?

a common fire extinguisher would do this job.
the reason a they don’t make a consumer version is a lack of need. you essentially take a compressed gas and and exhaust it quickly over whatever container of food you want to freeze. you could make a box for it (like a microwave) and just hook up a small robust compressor with a sealed gas (same gas as in your fridge.) you close the door, turn it on, it releases the compressed gas, you’ll want the machine to recover the gas after the process, and you’re done.
but nobody cares. it’s easier and less expensive just to put whatever you want frozen onto the freezer and wait a few hours.
