Desolventising


The de-oiled meal contains about 20% - 35% solvent by weight depending on the material. The meal must be desolventised.

The basic principal involved in Desolventation is direct heating of material with steam to a temperature well above boiling point of the solvent and thus ensuring no solvent is left over in the material. Toasting is also heating the material with direct and indirect steam to remove the remaining hexane and as well toast the meal.
