Development of the twin-screw compressor 2.1. Design parameters and rotor profile ... The oil-free twin-screw compressor developed is an air-cooled type and its casing is cooled by air convention. As can be seen in Fig. 6, ribs are designed on the outside surface of the casing to enhance the heat transfer.
Due to the growing need for the compressed air of higher quality, the water-lubricated twin-screw compressor with water as the only liquid in the compressor has drawn much attention to produce clean air absolutely free of oil.

The problems associated with the single screw expeller is that, it requires three or more passes to expel oil from seeds, which increases the production time and are also less efficient. In this paper, a counter rotating twin screw expeller is designed for extraction of oil from the Pongamia pinnata seeds.
