Abstract: The invention relates to a coffee grinder comprising two grinding discs (4, 5) that can be rotated in opposite directions, the axial distance between which defines the degree of grinding of the coffee powder produced. The grinding discs (4, 5) are mounted one over the other within a grinder body (1), the lower grinding disc (5) being rotatable about a vertical axis of rotation (6), while the upper grinding disc (4) can be adjusted non-rotatably and by an eccentric shaft (13) relative to the lower grinding disc (5) in the direction of the vertical axis of rotation (6). By rotating the eccentric shaft (13) with a motorised drive (17) the space between the grinding discs can be changed infinitely. This enables infinite regulation of the degree of grinding when preparing the coffee.

Abstract: Reducing apparatus includes a bottom rotor rotatable at a relatively high speed to provide relatively high centrifugal and G forces for reducing material disposed on the rotor. An upper conical element is disposed above the rotor and is free-wheeling relative to the bottom rotor, and thus rotates in response to rotation of the bottom rotor. Material to be reduced moves downwardly onto the bottom rotor through the conical element. High centrifugal and G forces resulting from the high rotational speed of the bottom rotor move the material outwardly to impinge upon the conical element for reduction. Vertical spacing between the two rotating members may be adjusted for varying the degree or extent of the reduction. The axes of rotation of the two members may be offset to provide additional G forces and a scrubbing action.

Abstract: High-shear treated materials are passed through a high-shear treatment zone which allows the coexistence of free supra-Kolmogoroff eddies larger than the smallest possible Kolmogoroff eddy diameter and forced sub-Kolmogoroff eddies smaller than this diameter. This zone includes a subsidiary higher-shear zone for suppressing these free eddies. The passage walls (40, 44, 102, 108) move relative to one another transverse to the flow to force the simultaneous development of supra-Kolmogoroff and sub-Kolmogoroff eddies while maintaining liquid films adherent to the passage surfaces. The movement produces only forced sub-Kolmogoroff eddies in the subsidiary zone while maintaining a non-turbulent flow. Ultrasonic oscillations (52) may be applied to cause elastohydrodynamic pressure and viscosity increases and/or production of smaller sub-Kolmogoroff eddies.

Abstract: The method for treating materials in liquids involves passing them with the liquid through a processing gap formed by a flow passage whose walls are closely spaced and move relative to one another transversely to the direction of flow, thereby producing "supra-kolmogoroff" mixing eddies in the gap, and at the same time applying ultrasonic longitudinal pressure oscillations that reverberate between the two closely spaced surfaces into the gap transversely to the direction of flow from transducers mounted on one wall, thereby producing "sub-Kolmogoroff" mixing eddies therein. The method is capable of rapidly producing relatively thick slurries of sub-micrometer particles that otherwise can take several days in conventional high shear mixers and ball or sand mills, or of rapidly dissolving difficultly soluble gases and powders into liquids.

The apparatus includes a manually operable loading bin for dumping containers (glass or plastic bottles and jars, metal cans, small cardboard boxes, etc.) into the wide upper inlet opening of a conical chamber. Motor-driven rotatable circular cutting blades, having sharp edges which project into the chamber through slots in the chamber wall, cut and break the containers descending through the chamber into small pieces of material (glass, plastic, metal, cardboard, etc.). The pieces exit the narrow lower outlet opening of the chamber into a selected one of several compartments in an adjustably positionable carousel below the outlet opening. The slots (and blade edges projecting therethrough) are arranged in three radially spaced apart vertical columns around the chamber wall.

Abstract: A solids comminuter having a circular series of upright abrasive rolls with upper end drive defines a central chamber to receive solids to be comminuted. A centrally apertured stationary bottom plate supporting the rolls defines an orifice partially covered by a free-turning screening plate to define an annular passage adjustable in width to form a size restriction gap. Driven by the swirling mass of solids pressing down against it, the screening plate drives a particle impeller housed in a receiving chamber underlying the screening orifice to pump the descending comminuted particles outwardly through a discharge passage in the wall of the receiving chamber.

Abstract: In an apparatus and method for comminuting solid material a plurality of comminuting rollers are journalled for rotational motion in a generally circular arrangement to form a tubular enclosure.

Puncturing elements on the rotating rollers operate to comminute the pieces of material by a rolling, puncturing action. In a preferred embodiment, the rollers are powered and are rotated conjointly to engage and drive the solid material orbitally. Additionally, an impeller may be employed to drive the material within the enclosure, and in yet another embodiment, the entire enclosure, including the rollers, is rotated.
