Abstract
In the desolventizing of solvent-containing residues which are obtained in the extraction from vegetable, oil and fat-bearing raw materials with organic solvents and from which the so-called miscella containing oil and/or fat has been separated, the desolventization proper by direct action of a desolventizing agent, particularly steam, is relieved by interposing before the desolventization proper a pre-desolventization with indirect heat transfer, particularly indirect steam heating, and thereby the energy input of the entire system is reduced considerably. Moreover, the drying and cooling of the now solvent-free residue, which follows the desolventizing, can take place in a single, combined stage, whereby further relief of the volume of apparatus as well as the energy input is achieved.
