These are general purpose mixers: you can mix doughs, batters, sauces and a lot of other things with a countertop, stand, or floor-model mixer.
Commercial mixers are found in grocery stores, bakeries, pizza shops, and supermarkets all across Canada. They are necessary for a lot of commercial kitchens to make their dough, mixes, sauces, or anything else that needs mixing.
A planetary mixer comes in three different sizes. Countertop planetary mixers, and bench planetary mixers, and floor model planetary mixers. Within each type of these, there will be various capacities, depending on the amount of stuff you'll be mixing.
A spiral mixer is a totally different beast. Based on how they mix, they are really designed for bakeries and pizza shops, for mixing dough. So if you're in a kitchen where you want to be mixing a lot of your own dough, we're really recommend going with a spiral mixer. Their dough capacity is way, way higher than a planetary mixer, and they are really going to be a lot more efficient. They were designed specifically for dough, which is why they are sometimes called "dough mixers."
One thing to note about all commercial mixers, and this is something you really should know: don't overwork your mixer. The number one issue we see with people using their mixers is that they're overworking it. Make sure you have a good understanding of how much stuff you want to be putting into your mixer, and also, very importantly, how OFTEN are you going to be putting stuff into your mixer. Some mixers are better at handling constant use, and others need time to cool down.
