Abstract: A food waste disposer has a grinding mechanism that improves fineness and speed of grinding food waste, and also controls or meters the size of the comminuted food waste particles that are discharged from the food waste disposer. It does so by utilizing a more aggressive grind ring of the grinding mechanism that includes horizontal shredder elements in addition to openings, and blocking all except the openings in a minor circumferential portion of the grind ring from discharging comminuted food waste and water to a discharge outlet. In an aspect, a resilient seal is used to seal the adapter ring to a housing of an upper end bell of the grinding section and also provide a seal for a rotating shredder plate assembly of the food waste disposer.

Abstract: A method of and system for liquefying snow. The system includes a rotor-stator device mounted within a melting reservoir and having a slotted rotor and a slotted stator. Snow and/or ice is deposited in a water bath in the melting reservoir. The rotor rotates at high speed, hurling particles of crystalline snow from the tips of the rotor slots onto the perpendicular faces of the stator, thereby fracturing the crystals and promoting liquefication. The high mechanical forces generated during operation of the rotor-stator device also contribute a significant amount of heat that is applied directly to the snow. The system also includes ancillary assemblies, such as heat-exchangers and snow-transport means. The system is operable as a stationary unit or a mobile unit.

Abstract: An apparatus for comminuting rocks, comprising a frame having a restrictive passageway with an inlet and an outlet end for relative displacement of rocks from the inlet to the outlet end. A rotary impacting device is secured to the frame in the passageway so as to be journaled with respect to the frame. The rotary impacting device has hammer elements on an outer periphery of the device. The hammer elements are adapted to scoop and impact rocks in the passageway to project the rocks toward the outlet of the apparatus. An actuator is mounted to the frame and operationally connected to the rotary impacting device for imparting a rotation of the rotary impacting device. A screen is adapted to comminute upon impact the rocks propelled thereon by the rotary impacting device. The screen is positioned at the outlet end such that comminuted rocks exiting from the apparatus are below a predetermined size.

Abstract: An ice shaver machine that includes a hopper for receiving ice, a blade and scraper for drawing the received ice across the blade, thereby producing thin, snow-like ice shavings or flakes, which are scraped to a spout, which, in turn, is provided for delivering the ice shavings to a container. The spout is shaped so as to be used to create a domed-like snow ball shape on the top surface of the shaved ice in the cup container. Also provided is a flavoring delivery system that permits the user to select a flavoring for addition to the ice shavings.

Abstract: A tearing mill for comminuting fruits (3) is equipped with a tearing bed (15) with tearing elements (4) and delivery vanes (5) for the fruits (3). Directly upstream of the tearing elements (4) in terms of the delivery direction (v), openings (16) for the comminuted pieces of fruit (8) are disposed in the tearing bed (15). As a result, low mechanical stress on the comminuted product (8) and a small proportion of fine particles are achieved, which improves the yield and output in an ensuing juice extraction operation.

Abstract: The present invention is an improved rotary granular material cutting apparatus and knife blade assembly. The apparatus comprises a perforated drum that may receive granular material into its interior. The grains of material extend through perforations in the spinning drum where they encounter a series of knife blades. The blades are arranged to form angles of contact with tangents to the spinnig drum. Those angles of contact are steeper on the side regions of the spinnig drum than on the bottom regions. The apparatus also includes a grooved interior baffle to disburse input material within the drum, and knife-mounting wedges that include toe or base stops to help secure knife blades in arrangement about the drum.

Abstract: A gas-flow type chipping machine with a rotating beater-wheel system. In order to chip the feed material, this material is delivered axially into the central area of the beater wheel, where it is deflected and moved in a radial direction to the chipper tools that are arranged in a circle around the beater wheel. In order to ensure that the wear is even along the length of the chipper tools, at least two impact surfaces are arranged so as to be axially staggered to the depth of the chipping space, the impact surface that follows in the axial direction of delivery projecting beyond the axial projection of the preceding impact surface. In addition to the foregoing, the present invention discloses a method for optimizing the size and position of the impact surfaces of a chipping machine according to the present invention.

Abstract: An apparatus for mixing, grinding, dispersing or emulsifying including a rotatable drive, a rotor body connected for rotation with the drive and having at least one aperture for fluid flow through the rotor body and a flow divider plate structure extending within the rotor body for preventing conglomeration of particulates contained within the fluid in the rotor body. Preferably, a stator body is secured outside of the rotor body and each of the rotor and stator bodies include respective apertures for allowing fluid flow therethrough. The flow divider plate structure prevents the usual swirling action of liquid and solid particulates within the rotor body such that the mixture has a more desirable flow pattern and so that particulates do not conglomerate to form a mass that clogs the rotor body. Further aspects and embodiments of the invention provide advantageous seal structure and structure for increasing productivity.
