The shredding device in accordance with the present invention includes a housing, a rotary shaft rotatably attached to an inside of the housing, a plurality of rotary blades attached around the rotary shaft to be spaced apart from one another in an axial direction of the rotary shaft, and a fixed blade attached to a bottom plate of the housing so that an article to be processed is shredded between the fixed blade and the rotary blades, wherein a lifting device which changes a distance between a tip of the rotary blade and a tip of the fixed blade by raising and lowering the rotary shaft is provided.

A cyclonic separation and materials processing method and system is presented in which materials entry at one end and which is arranged so that the materials that enter will be given a tangential velocity component as they enter. Specific embodiments include a three-dimensional sorting system with the use of an outward centrifugal motion and up/down (or vertical) motion flow of water or other media, which can be thought of as “a three-dimensional separation”.

The present invention provides a waste system including a disposal with multiple inlets that can receive water and waste materials from multiple basins.

A kitchen waste processor includes a base including a basket which has a heater located therein. A driver rotates the basket which is pivotably supported by a support. A container is located in the basket and protrudes beyond the open top of the basket. A cover has a hole defined centrally therethrough, and a seal is located within the hole. A vacuum suction pipe or a blade shaft extends through the hole. A locking device is located between the container and the cover to seal the cover to the container. The container receives kitchen waste and bacteria therein. The heater heats the container while the container is driven by the driver to spin, so that the kitchen waste in the container is fermented under high temperature to transfer the kitchen waste into fertilizer.

The invention relates to the field of kitchen appliances and discloses a food waste disposer, the food waste disposer has a switching component arranged to a discharge outlet of the food waste disposer, the switching component has a first pipe; a second pipe; a first baffle that flips in an anti-gravity direction along a discharge direction to connect or isolate a discharge outlet and a sewer pipe; a first sealing ring; and a limit block to prevent the first baffle from flipping. The invention also discloses an integrated sink and integrated cabinet both have the food waste disposer with a switching component arranged to a discharge outlet of the food waste disposer.

The present invention discloses a shredding mechanism, a shredding device and a control system and method thereof. The shredding mechanism comprises a shredding component and an adjusting component, wherein the shredding component is used to shred materials, the adjusting component and the shredding component define an operation space for shredding operation, and the adjusting component and the shredding component are configured to be able to move relative to each other so as to change the size of the operation space. The present invention also discloses a shredding device and a control system and method thereof. The shredding mechanism and device according to the present invention feature improved safety, convenience and service life.

A dual auto-feed paper shredder provides a housing open at a top side to allow access to a paper compartment disposed within the housing. The paper compartment includes a bottom surface defining two side-by-side paper stations and a centrally located input slot extending across the bottom surface. Each paper station is configured to accommodate one stack of paper disposed above the input slot. Two sets of counter-rotating spaced apart rollers disposed on either side of the input slot. Each set is associated with a particular one of the paper stations. The housing includes an internal compartment configured to hold a shredding mechanism disposed below the input slot such that sheets of paper pass through the input slot into the shredding mechanism. At least one lid is hingedly connected to the housing, and is rotatable between fully open and fully closed configurations. The at least one lid is disposed over the paper compartment in the fully closed configuration.
