An auto-feed paper shredder is configured for placement below the surface of a desk. The auto-feeder consists of a drawer located on the front surface of the shredder. This drawer is slid out to insert a stack of documents to be shredded. When the door is slid back into the shredder and the shredding system is activated, feed rollers draw sheets of paper either from the top or the bottom surface of the stack and feed the sheets into a conventional paper shredding mechanism. An input slot is provided to insert single sheets of paper when the auto-feeder is not being used.

The paper shredder simultaneously shreds both manually inserted sheets of paper and sheets of paper that are placed in an auto-feeder input tray. Immediately above the shredding mechanism the input path is bifurcated. One branch extends essentially straight up from the blades and leads to a manual input slot. A second branch extends at an angle towards the rear of the shredder where an auto-feed roller lies at the bottom of an auto-feed slot. When a stack of paper is placed into the slot, the bottom of the stack rests against the auto-feed roller which grasps the top sheet and pulls it under the roller. The roller then pushes the sheet down the angled throat where a curved surface bends the sheet downwards and into the shredding mechanism.

A plastic granulator apparatus stationary cutting segment includes a segment rail having multiple arcuate spaced teeth. Each tooth of the plurality of arcuate spaced teeth has a tooth surface and is spaced to be complementary to a rotary cutter segments as a rotary cutter is rotated. The segment rail is adapted to be mounted to a granulator housing. The rail segment has a shoulder with a shoulder surface, the shoulder is adjacent to each of a set of arcuate spaced teeth. The shoulder has a shoulder surface height of between 0 and 10 mm, and a stepback distance of between 0 and 2 mm between the shoulder surface and the arcuate tooth surface. The shoulder and the arcuate tooth surface define an angle therebetween of 90° and 130°, and the shoulder surface defines an angle between 90° and 130°.

A cutting blade assembly establishes a bidirectional and/or multifaceted scissor-type cutting action to efficiently and effectively process various types of debris encountered by the cutting blade assembly. The assembly includes a cutting plate and a cutting hub configured for relative rotation. A cutting slot is formed in the cutting plate and intersects the axial face to define a cutting edge at the intersection of the cutting slot and the axial face. The cutting hub has a cutting arm positioned adjacent to the axial face. When the cutting plate and the cutting hub undergo relative rotation, the cutting arm passes adjacent to the cutting edge to perform a scissor-type cutting action.

A read unit of a scanner device reads the information fixed to a medium by printing. A transmission control unit executes the control of transmitting, to a server, the information of the medium acquired in the form of digital image data. An information acquisition unit acquires the information transmitted from a shredder. An information management unit stores the information acquired by the information acquisition unit in an acquired information database in such a way as to be identified as the information of the medium so as to be managed to be capable of being read out as the information of the medium. An information readout unit acquires a readout indication transmitted from an observer terminal. Then, the information readout unit reads the information of the medium out of the acquired information database via the information management unit.

Automatic paper shredder having a paper pressing mechanism, which includes upper shredder cover, lower shredder cover, paper support box, paper pressing plate, cover plate, spindle and two spindle holders. Upper cover is connected to lower cover. Paper support box is above the lower cover forming a cavity for to-be-shredded paper. Fixed ends of paper pressing plate and cover plate are around the spindle, so free ends of paper pressing plate and cover plate can rotate coaxially. Two ends of spindle are respectively disposed in two spindle holders, so spindle can rotate. Two spindle holders are connected to upper cover to connect cover plate and paper pressing plate to upper cover. Paper pressing plate is disposed below cover plate and for pressing to-be-shredded paper placed on paper support box when a user closes cover plate.

There is provided an organic waste processing device comprising: an organic matter-receiving container defining an organic matter-receiving chamber; a gas-propelling unit; a gas-plenum chamber in gas communication with the gas-propelling unit; and a grinding assembly at least partially contained in the organic matter-receiving chamber. The grinding assembly comprises a drive shaft and a rotatable blade assembly including a blade support sleeve mounted to the drive shaft and being engaged in rotation therewith. The rotatable blade assembly further includes at least one blade mounted to the blade support sleeve. An inner surface of the blade support sleeve is spaced-apart from an outer peripheral surface of the drive shaft to define a gas flow channel extending longitudinally into the griding assembly and providing gas communication between the gas-plenum chamber and the organic matter-receiving chamber.

An automatic shredder having an upper shredder cover, a lower shredder cover, a first paper box, a second paper box, a shredder cover plate, a paper pressing plate, a paper pressing roller set, a paper pick-up roller set, a paper inlet, a cutter shaft set, a drive motor, a shell and a waste paper barrel. The automatic shredder adopts a bent paper box to change the length of to-be-shredded paper by means of the flexibility and bendability of paper and the features of paper pick-up rollers on one side, is extremely simple and economical, and changes the flat paper placement structure of existing automatic shredders.

Waste separator apparatus which comprises: -a frame (11) which delimits a separation chamber (12); -a screening mesh (13) which divides the separation chamber (12) into a shredding chamber (121) and a collection chamber (122); wherein the shredding chamber (121) has a loading mouth (123) and an unloading mouth (124); - a shredder shaft (14) fixed to the frame (11) in a rotatable manner about an operating axis (A) and extending into the shredding chamber (121). The shredder shaft (14) has first cutting hammers (15) and second expelling hammers (16); wherein the screening mesh (13) faces the first hammers (15), in order to receive shredded material, and the discharging mouth (124) faces the second hammers (16). The second hammers (16) have a front edge (17) which is rectilinear and extends substantially parallel to a radial direction (C) with respect to the operating axis (A).

A food waste disposer system (300) has active noise control of food waste disposer noise that is generated by the food waste disposer (302) when a motor of the food waste disposer (302) is running. The food waste disposer (302) has a food conveying section that conveys food waste to a grinding section. The grinding section has a rotatable shredder plate that is rotated by a motor of a motor section. Active noise sound waves (310) are radiated into an area (313) where the food waste disposer noise is to be controlled at an amplitude and frequency to at least cancel or mask the food waste disposer noise.
