Abrégé

An oil bearing vegetable material crushing process including pre-heating and pre-drying the material to generate warm, partially dried oil bearing vegetable material. The partially dried material may then be surface heated rapidly, to generate warm and dried material having a weakened and non-adhering hull. The hull may then be mechanically cracked and removed to yield dehulled oil bearing vegetable material and hull. The dehulled material may be flaked to produce flakes. The flakes may be solvent extracted to generate solvent laden oil and solvent laden meal. The solvent laden meal produced may be desolventized to generate hot, wet meal. The wet meal produced may be dried to generate a hot vapour stream. The hot vapour stream generated by drying the meal is condensed in a condenser. The warm liquid medium produced in the condenser may be used to pre-heat and/or pre-dry the oil bearing vegetable material.

Abrégé

An oilseed crushing process wherein the oilseeds are preheated to generate warm, soft oilseeds, then flakes are generated by flaking the warm, soft oilseeds. The flakes are then cooked by generating a hot vapour stream and hot flakes. The hot flakes are then prepressed to generate oil and a partially de-oiled cake. The partially de-oiled cake is solvent extracted to generate solvent laden oil and solvent laden meal. The hot, wet meal is then dried to generate oilseed meal and an additional hot vapour stream. The at least part of the preheating step to generate warm, soft oilseeds is accomplished using a hot liquid medium. The hot liquid medium is heated by a heat transfer mechanism that condenses at least one of the hot vapour streams generated during the flake-cooking step or the meal-drying step.
