Abstract:
1. A rotor for food pulping and straining machines comprising: a plurality of blades designed to act on a food product to force at least part of the food product out through a sieve that surrounds the rotor, wherein surface edges of the plurality of blades facing the sieve and defining an axial direction have at least one notch said notch having a longitudinal axis making an angle α with said axial direction of each of the plurality of blades the angle α varying between 10° and 80° or between 100° and 170° relative to the surface of the blade so as to cause sudden changes of direction in moving food product particles, thus producing a rapid succession of impulses that act on substantially stationary food product particles adhering to the sieve said impulses causing the substantially stationary food particles to be detached from the sieve.
