séchage éclair

OBS: [...] sous le nom de ""flash roasting"" (qu'on peut traduire par grillage éclair), on désigne la technique de Freeman [...] qui consiste à brûler littéralement la pyrite finement pulvérisée.

CONT: Two other heat-treating processes applied in sludge incineration are the flash-drying incineration system and the fluidized bed reactor. Flash drying involves pulverizing wet sludge cake with recycled dried solids in a cage mill. Hot gases from the incinerating furnace suspend the dispersed sludge particles up into a pipe duct where they are dried. A cyclone separator removes the dried solids from the moisture-laden hot gas which is returned to the furnace.
