Currently you can't have an automated mixing bowl in your kitchen and still have it count as a room because the automated mixing bowl does not count as an insulating block. This is quite unfortunate as it means you're unable to have a properly sealed kitchen unless you opt for a manual mixing bowl. It might not be realistic with the current model of the automated mixing bowl, but it could easily be modified by adding a bit of planks to the sides if that would really be a concern.
