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.
Boiling rates (gallons per hour), fuel consumption (wood vs. oil), and heat distribution across the 48-square-foot surface. 2. Historical & Industrial Evolution Grimm_4x12
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. This paper would analyze the efficiency of the
