If you are referring to the device shown in this YouTube video, , it is called an AutoCheeser, or Khalid's AutoCheeser, after the person who developed the unit for Domino's. The unit is manufactured exclusively for Domino's but I have read that from time to time they can be found on eBay. As I understand it, the unit only distributes the cheese--which apparently is diced--over the pizzas. It does not portion the amounts of cheese based on pizza size. As shown in the video, workers scoop the cheese into the AutoCheeser from the top. I believe that the largest size pizza that the unit can handle is 16" but I am not absolutely certain on that.
