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.
An apparatus 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, wherein 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, the cooler further comprising 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.
A process for the continuous prepressing of oleaginous vegetable material comprising the steps of subjecting an oleaginous vegetable material in a prepress to a mechanical prepressing to extract at least part of the oil contained in the oleaginous vegetable material, in particular at least 30%, and compressing said oleaginous vegetable material to produce a vegetable oil and a partially de-oiled cake of a oleaginous vegetable material, cooling said cake, by subjecting the cake to a downward movement and by contacting the cake with a rising counter current flow of a coolant gas, in particular air.
