Rotor blades for food processing machines
First Claim
Patent Images
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.

Abstract
A rotor for food pulping or straining machines is equipped with a plurality of blades (2) designed to act on the food product to force at least part of it out through a sieve (3) that surrounds the rotor (1) and is characterised in that the blades (2) are shaped in such a way as to cause sudden changes of direction in the moving product particles, thus producing a rapid succession of impulses that act on substantially stationary product particles adhering to the sieve (3), these impulses causing the propulsion of the substantially stationary product particles.
