The present invention relates to a food waste disposer that is configured to allow an opening and closing plate adapted to open and close a drain pipe to be open only when a motor operates, so that normally, the drain pipe from which water is discharged is closed, thereby preventing bad smell and sewage from flowing backward from the drain pipe, to allow a propeller adapted to forcedly discharge the water from a casing to the drain pipe to be driven reversely and to thus close the opening and closing plate if the motor is driven reversely, so that gears inside a pulverizing part rotate to circulate the water in the casing and thus to automatically clean the casing, without any separation of the casing, and to allow a magnetic material to be built in a hopper so that if iron introduced into the hopper is sensed by sensors, the pulverizing part stops working and is thus prevented from being damaged by the iron.

A kitchen garbage processor, includes: a processor body, a dewatering component, and an oil-water separating component, the processor body has a working platform disposed thereon, an inlet for dumping kitchen garbage is disposed on the working platform, a fore end of the dewatering component is communicated with the inlet and configured to send a kitchen garbage that to be processed to the dewatering component to separate a solid garbage from a liquid garbage; a solid garbage outlet configured for sending out a processed solid garbage and a liquid garbage outlet configured for sending out a residual liquid garbage are disposed at a rear end of the dewatering component; a fore end of the oil-water separating component is communicated with the liquid garbage outlet so as to send liquid garbage that to be processed to the oil-water separating component to separate oil from water; an oil outlet configured for sending out separated oil and a water outlet configured for sending out separated water are disposed at a rear end of the oil-water separating component. Purpose of separating solid garbage, oil and water simultaneously is realized.

A reversible grinder pump with cutter plate and cutter blade, wherein the cutter plate is attached to an inlet of the reversible grinder pump and is located adjacent to the cutter blade, wherein the cutter plate includes pairs of angled openings, wherein each of the pair of angled openings extends through the cutter plate and has a shape which is a mirror image of the other angled opening of the pair of angled openings, when viewed from above a surface of the cutter plate. The cutter blade of the reversible grinder pump contains a pair of triangular cross section, prism-shaped cutting edges, which are congruent to each other and reflective, extending in opposite directions from each other.

A system for comminuting solid waste material including a shredding device disposed within the casing and comprising parallel first and second shredding stacks that include first and second parallel shafts rotatably mounted between an upper shredding device housing and a lower shredding device housing and a rotating screening drum disposed within the casing and mounted between an upper screening drum housing and a lower screening drum housing, the rotating screening drum configured to permit fluid to pass therethrough while capturing solids on an outer surface for delivery to shredding device, an upstream portion of the rotating screening drum disposed upstream of an upstream portion of the shredding device. The upper shredding device housing and the lower screening device housing are separate members from the upper screening drum housing and the lower screening drum housing to permit interchangeability of different sizes of these components to meet system needs.

A system for comminuting solid waste material including a casing defining a comminution chamber having two side walls and adapted for connection in a solid waste disposal channel. The system includes a first shredding device and a second shredding device disposed along a line extending perpendicular to a flow direction in the channel to faun a pair of interactive shredding members. A rotating screening drum disposed within the casing upstream of the first and second shredding devices and positioned between the first and second shredding devices, the rotating screening drum configured to permit fluid to pass therethrough and to move solids toward one of the shredding devices. The rotating screening drum is configured to rotate clockwise and counter clockwise to alternately distribute solids captured thereon to one of the first and second shredding devices.

A method for comminuting kitchen waste and/or food residues includes receiving kitchen waste and/or food residues in a funnel, a base of which is provided with a grinding unit for comminuting the kitchen waste and/or food residues and which is connected by the grinding unit via a product line to a pump for pumping away comminuted kitchen waste and/or food residues, and pumping away the kitchen waste and/or food residues comminuted by the grinding unit. Prior to the pumping-away step, precomminution of the kitchen waste and/or food residues located in the funnel is carried out in the funnel by means of a precomminution unit projecting into the funnel. A correspondingly designed device for implementing the method is also described.

A self-cleaning garbage disposal system is provided including a container having a neck portion leading to a container opening and a flow switch valve for connecting the container to a dishwasher drain hose. The flow switch valve is switchable to an open position to allow dishwasher water to be fed to the container from the dishwasher drain hose and to a closed position to not allow dishwasher water to be fed to the container from the dishwasher drain hose based on a rotational position. The garbage disposal system can include a garbage disposal cap to be rotationally inserted into the container opening, and the flow switch valve operation can respond to the rotational position of the garbage disposal cap. Sensors can be provided on the garbage disposal cap and the neck portion of the container to detect the rotational position of the garbage disposal cap.

A food recycler can include a housing defining an interior and an access opening to the interior. A mixing bin can be located within the interior and can have an inlet and an outlet. The food recycler can further include an output bin, the output bin having an inlet. The outlet of the mixing bin can couple or connect to the inlet of the output bin.

A comminution apparatus, a method for replacing wear parts of such an apparatus and a cutting table unit for use in such an apparatus are disclosed. The apparatus comprises a cutting module, a drive module and a top module. The main wear parts are present in the cutting module, which may be replaced, in its entirety or in part, without disconnecting the drive module from the apparatus or from an external power source.

A conveying screw for a food waste disposal device that can stir, crush and cut food waste generated from homes or restaurants, while transferring the food waste, to reduce the amount of the food waste, includes a rotational shaft, and a plurality of spiral rotor blades installed to an outer peripheral surface of the rotational shaft in a spiral pattern to stir, crush and cut food waste. Each of the rotor blades is provided with a plurality of air supply holes penetrating the rotor blade to supply external air to the food waste between the opposite rotor blades, thereby generating bubbles from the food waste and then discharging vapor.
