| 摘要 |
The invention relates to a screw for a screw-type solid bowl centrifuge that is characterized in that additional leaf segments (29) are disposed in some sections of the conveyor path (7) between adjacent spirals (x, x+1, ). The screw leaf (5), in the area of the screw leaf segments (29), is preferably provided with recesses (27) that are adapted to allow the material to be extracted (S) to pass between adjacent spirals (x, x+1, ). The screw according to the invention is especially suitable for use in a method for producing oil from fruit and seeds and for better dehydrating and/or deoiling mashes of organic materials (for example mashed seeds, fruit pulp, animal tissues such as fish, egg, fatty tissue cells).
