How often can you make it through a stack of 40 negatives in seven minutes? (Let's see, five seconds per flop time 40 = 200 seconds; seven minutes is 420 seconds; that means not even three times through the stack in an entire development cycle??)
Maybe I'm not understanding completely.
I tray develop, 6-8 per batch and can do five to ten batches comfortably in a day. That's 30 - 80 negatives in a day's work. I don't know if that's high-enough volume for the OP. Newspaper darkrooms used open tanks and nitrogen burst agitation. The time-consuming part was loading the film into hangers. Dip-and-dunk tanks with hangers can do quite a bit of volume too.
Best,
