PHOTOGRAPHER’S JOURNAL: My friend Bob tells me that the filters shown in yesterday’s photo were "cyclones, precleaning units that remove large cinders before the exhaust gases go thru the bag houses - which are like large vacuum cleaners filled with cloth bags that filter the air -- the rectangular boxes are the bag houses - the dust is collected in the hoppers at the bottom."
Somewhere I have photos of the collected bags waiting for disposal from bag houses in the Waterbury tube mill. I enjoy knowing that the name for giant pastry squeezers is “cyclones,” while still appreciating that its all pasta.
