Worm press for expressing foodstuff containing fluid, particularly seeds containing oil

摘要

A filling aperture is preferably arranged in the housing cover wall and is connected to a funnel. It is intended for the material to be expressed. An expressing zone of the cover wall is provided with a number of through apertures for the fluid. At the end turned away from the filling aperture is a nozzle for the outlet of expressed material. The axes of the holes (12) are inclined relatively to the radial direction of the housing (1). The direction of inclination, viewed from the inside outwards, is selected counter to the circulating direction (6) of the worm (3) and the cross-section of the holes (12) from the inlet end to the outlet end continually increases.
