Abstract
A continuous process for heat treating flowable materials having liquids thereon and apparatus wherein a first portion of adhering liquid is vaporized in a pre-desolventizer (PDS) consisting of at least one horizontal steam jacketed conveyor tube (60-63), the vaporized vapors of the liquid being directly discharged into a desolventizer (DS) consisting of a vertical chamber being divided into a certain number of compartments (70-73), live steam is introduced into the lowermost compartment (73) to vaporize the remaining portion of liquid adhering on the material and the combined vapors of liquid collected in the upper section of the desolventizer (DS) are discharged into a condenser (91) where a dust-free liquid is recovered. The desolventizer (DS) may also be used as a combined desolventizer-toaster-dryer.
