Bunn-O-Matic iMIX-3S Oatmeal is a machine designed to make instant oatmeal. It has three hoppers, each of which can hold a different flavor of oatmeal. The machine also has a 4.3-gallon (16.3L) hot water tank, which is large enough to meet peak serving times. The front of the machine has large, lighted graphics for merchandising, and the key service components are easily accessible through the front, top, and easily removable side panels. The machine also has a spring-loaded, all-metal auger drive system for easy hopper installation, and a front-of-machine set up and calibration.
