Twin-screw extrusion technology for vegetable oil extraction
The design consists of a pilot-scale partially intermeshing, counter-rotating twin-screw extruder-press with a barrel composed of vertical, parallel plates varying in diameter. The twin-screw press operated at a feeding rate of 50–58 kg/h and attained a high oil recovery of 94% for dehulled sunflower seeds.
Single-screw extrusion (expander) is mostly employed at a large-scale for the pressing of oil from seeds, but twin screw systems are used in laboratory and pilot studies [18,23].
Twin-screw extrusion technology for vegetable oil extraction
Conclusions. Twin-screw extrusion technology exhibits promising perspectives in the field of vegetable oil extraction, especially when integrating several extraction stages in a single extruder passage. However, extensive additional research is crucial in order to further develop these processes and assess their industrial feasibility.
A versatile twin-screw extrusion process to provide an efficient thermo-mechano-chemical pre-treatment on lignocellulosic biomass before using it as source of mechanical reinforcement in fully bio-based fiberboards was developed, resulting in a marked increase in the average fiber aspect ratio.

The oil levels remaining in the cake can be reduced to less than 2% by solvent extraction. However, the crude oil has to be refined as it contains many impurities and approximately 600 ppm phosphorus. A new process, in which sunflower seeds are pressed in a twin-screw extruder, is examined here. The screw profile was first optimized.
This study presents an assessment of the vegetable oil extraction from coriander fruits through mechanical pressing, more specifically twin-screw extrusion. This comprises an evaluation of the oil recovery obtained and its respective quality, as well as the specific mechanical energy, representing an economical point of view.
Twin-screw extruder for oil processing of sunflower seeds
A new application of twin-screw extruder as a machine to conduct a thermo-mechanical pressing and a solvent extraction of sunflower oil in a single step and in a continuous mode was studied. Experiments were conducted using a CLEXTRAL BC 45 co-rotating twin-screw extruder and whole sunflower seeds with fatty
However, the oil yield is overall lower, due to a significant amount of fat retained in the press cake (10, 12 %). Heating up the seeds before pressing (e.g. in stack heaters) considerably increases the yield, at the cost of lower oil quality. Extrusion–pressing can lead to high oil yields.

Oil content of baobab seeds is about 10 – 30%. The cleaned Baobab Seeds are subjected to conditioning in a vertical / horizontal stack cooking kettle. The kettle uses steam for indirectly heating the Baobab Seeds. The kettle is specially designed to achieve a temperature of minimum 110°C at the outlet with a retention time of minimum 60 minutes.
