摘要

The V-shaped bucket comprises two walls (2,3) connected by a rounded bottom (4). It has two sides and a product outlet orifice as well as a worm (8) located in the bottom. The transverse section of the bottom has the shape of a circular arc defined by an angle (alpha ) greater than 180 degrees. The distance between the two ends of the arc is less than the diameter of the worm. The worm has a hollow core (16) supporting externally a helicoidal thread (17).
