  • Patent number: 10647077
    Abstract: The present invention relates to an apparatus and a process for subjecting oleaginous vegetable material to a continuous prepressing for extracting at least part of the oil contained in said oleaginous vegetable material and producing a cake comprising an at least partially de-oiled oleaginous vegetable material. The apparatus comprises a mechanical prepress for mechanically compressing said oleaginous vegetable material, wherein the prepress is provided with a cake discharge for discharging the cake to a cooler. The cooler comprising means for subjecting the cake to a downward movement, and means for supplying a coolant gas, preferably air, in a counter-current flow to the downward movement of the cake with the purpose of cooling the cake.

  • Patent number: 9371503
    Abstract: 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 vapor stream. The hot vapor 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.

  • Publication number: 20160076813
    Abstract: A heat exchanger includes a housing including an inlet for receiving bulk solids, and an outlet for discharging the bulk solids, a plurality of spaced apart, substantially parallel heat transfer plate assemblies disposed within the housing, between the inlet and the outlet for heating the bulk solids that flow from the inlet, through spaces between the heat transfer plate assemblies, and at least two gas handling zones including a first gas handling zone and a second gas handling zone spaced from the first gas handling zone, the two gas handling zones disposed between the inlet and the outlet for entry of a pulsed flow of air into the housing and around the bulk solids and for exit of the pulsed flow of air from the housing.

  • Patent number: 8951593
    Abstract: 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 vapor 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 vapor 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 vapor streams generated during the flake-cooking step or the meal-drying step.

  • Patent number: 7078003
    Abstract: The invention relates to a device for the transfer between a solid matter and a liquid, comprising an outer drum and a perforated inner drum, means for commonly rotating the drums, and means situated inside the inner drum for moving the solid matter. In between the two drums, a number of troughs are formed which, during the rotation of the drums, bring up liquid and pour it out higher up through the inner drum. Along the front rim of each trough, the drum is provided with a drain opening, opposite to which means are provided for preventing, when the drain opening, during the rotation of the drums, is at the bottom, the penetration of solid matter through said opening.

  • Publication number: 20030012713
    Abstract: The invention relates to a device for the transfer between a solid matter and a liquid, comprising an outer drum (1) and a perforated inner drum (2), means (4-5) for commonly rotating the drums (1 and 2), and means (18) situated inside the inner drum (2) for moving the solid matter (10). In between the two drums (1 and 2), a number of troughs (21) are formed which, during the rotation of the drums (1 and 2), bring up liquid (8) and pour it out higher up through the inner drum (2). Along the front rim of each trough (21), the drum (2) is provided with a drain opening (23), opposite to which means (24;26) are provided for preventing, when the drain opening (23), during the rotation of the drums (1-2), is at the bottom, the penetration of solid matter (10) through said opening.
