Abstract
The present disclosure describes embodiments of a twin-screw press for extracting vegetable oils, and a process for extracting vegetable oils and/or seeds. Particularly, the twin-screw press provides a reduction in machine cost and maintenance due to low operating torque requirements and allows an improved operation with the oil extraction being greater than the oil loss. This is a consequence of allowing lower processing temperatures and pressures due to the geometry of the screw and the gap that it has with the draining element of the press cage. This also permits reducing the possibility of material jamming or co-rotation of the cake in the press.
Claims15
A twin-screw press for extracting vegetable oils, comprising:
- a press cage, including;
- a feeding section located in a proximal zone of the press cage;
- a cake discharge section located in a distal zone of the press cage;
- a medial section located between the feeding section and the cake discharge section;
- a draining element located in the medial section and configured to retain a cake comprising vegetable solids and drain vegetable oil;
- a first screw and a second screw, and arranged inside the press cage, each screw, including:
- a shaft arranged inside the press cage;
- a flighting arranged on the shaft;
- a distal end mounted in a bearing housing;
- a proximal end mounted in a bearing housing;
- wherein at least one end of each screw is configured to be connected to a power transmission unit;
- wherein the screws are intermeshed between them overlapping;
- and
- a discharge-restricting device connected to the cake discharge section and configured to control a cake flow.
