Does your Air Fryer not cook evenly? This may be why.

When I first used an air fryer I started noticing that there were different hot spots in it.
One day, I was experimenting with making rice in the air fryer and noticed the water swirling making a small whirlpool. It hit me that this would be a good method of finding out why I had different hot spots in the air fryers.
For an air fryer to not have multiple hot spots the center of the air needs to be in the middle of the air fryer and the bottom should be round to eliminate any turbulence in the air.

What to fix it if it cooked evenly right from the begining then it doesn't any more?! just one side content of the basket
