How do you clear the pink spinning machines in the upper levels?

I think of them as cotton candy machines but I am not sure what they are.  They spin faster each turn until the change/block a piece

These are the evil spawners. They can be destroyed with boosters or by matching the candies next to them. 

There is a lot of information about it here: http://candycrush.wikia.com/wiki/Evil_Spawner 

Hope it helps!
