1) I cannot argue with a commercial chef about what he wants to use in his kitchen. But are these for high-volume production?
2) I imagine that in a restaurant kitchen, you probably have many countertop convection ovens going all the time. What I have found is my air fryer heats up very fast compared to my small convection oven. The difference is that the former has a plastic body, while the convection oven has a lot of metal parts.
3) Another thing is that household appliances would not last long under heavy-duty use in a commercial kitchen. Hence, an air fryer for commercial use would be like a heavy-duty convection oven.
4) I don't know how big the pressure cooker you use for canning, but if I want to make one quart of stock like I do with the Instant Pot, it probably just sloshes at the bottom of your cooker.
5) And how big is your convection oven that you use for baguette? A baguette is usually 26" and can be as long a 1 meter. My wife has to use the range oven when she makes bread. Our air fryer is for heating small portions. Using anything larger is like using a 50-cal gun to hunt rabbits.
6) PS. I dunno about some of the other gadgets you mentioned though. Many are gimmicks.
