"... football-field-long ovens for drying layers of material that have been dissolved in solvents..."
Hyperbolic language meant to spur some sort of emotional reaction, I guess?
This process : deposition of a dissolved solid and then the solvents being driven of by a long, gentle drying process, is pretty common in industry as a method. For example just about every self adhesive product uses this process for its release coating.
