This paper would analyze the efficiency of the "drop flue" design commonly found in these pans. Drop flues increase the surface area exposed to the fire, allowing for faster evaporation.
A historical look at how G.H. Grimm’s early patents in the late 19th century led to the standardized large-scale evaporators used today. Grimm_4x12

The transition from flat-bottom pans to high-efficiency flued pans and the shift from "English tin" to modern stainless steel. 3. Economic/Operational Case Study Grimm’s early patents in the late 19th century
Labor hours saved by larger pan surface areas, cost of maintenance (argon welding for leaks), and resale value of used equipment.
Aimed at producers with roughly 5,000 to 8,000 taps who are considering upgrading. As operations grow, a "conventional" 4x12 pan may become a bottleneck, requiring a move to more advanced "extreme" or steam-assisted systems.
