That was the machine we had in the dish room at St. John's University, Collegeville, when I was a student there from 1990-94. I spent 2 summers feeding and harvesting dishes from that beast! Ours was steam-fed from the central plant.

It was installed in the summer of 1991. Previous to that we used an earlier model most likely from the 1970s. It was frightening and we had to wear ankle boots to keep our shoes dry. The new machine was a cause of great rejoicing in the fall of 1991!
