Abstract
The device comprises a stator with gear rings and a rotor with teeth meshing with the teeth of the stator. Between arms of the rotor protrudes a guiding funnel that concentrates the material flow coming in from above to the central area of the container. The outer surface of the guiding funnel defines an annular gap throttling the material flow. At the rotor, a feed screw is provided that feeds towards the working region of the device. The guiding funnel retains the product in the active region of the device and the feed screw generates an increased material pressure in the center.

A device for processing materials comprising a container including a vertical container chamber having a product inlet at a top, a stator with concentric gear rings arranged about a vertical axis, a rotor with a plurality of arms with teeth engaging between adjacent teeth of said concentric gear rings, a guiding funnel arranged in the container chamber above the rotor, a funnel opening of said guiding funnel having a smaller diameter than the rotor, and the guiding funnel having an outer surface that is less steep than an inner surface.
A device for processing materials comprising a container including a vertical container chamber having a product inlet at a top, a stator with concentric gear rings arranged about a vertical axis, a rotor with a plurality of arms with teeth engaging between adjacent teeth of said concentric gear rings, a guiding funnel arranged in the container chamber above the rotor, a funnel opening of said guiding funnel having a smaller diameter than the rotor, the funnel opening protrudes into the rotor, and the guiding funnel has an outer surface that is less steep than an inner surface.
A device for processing materials comprising a container including a vertical container chamber having a product inlet at a top, a stator with concentric gear rings arranged about a vertical axis, a rotor with a plurality of arms with teeth engaging between adjacent teeth of said concentric gear rings, a guiding funnel arranged in the container chamber above the rotor, a funnel opening of said guiding funnel having a smaller diameter than the rotor, and an outer surface of the guiding funnel and an inclinded bottom surface of the container forms an annular gap for piling up material flow.
A device for processing materials comprising a container including a vertical container chamber having a product inlet at a top, a stator having a working surface formed as an inner cone with concentric gear rings arranged about a vertical axis, a transition surface of said stator merging with said stator working surface, a rotor with a plurality of arms with teeth engaging between adjacent teeth of said concentric gear rings, an overflow in an upper container portion above the stator working surface and the stator transition surface, a guiding funnel in the container chamber above the rotor, a funnel opening of the guiding funnel having a smaller diameter than an adjacent opening of the rotor, and said funnel and stator transition surface defining an annular gap through which processed material passes to said overflow.
