A waste processing machine for reducing waste material and having a safety device for shearing lines. A housing defines a cutting chamber and an intake opening in communication with the cutting chamber for receiving waste material. A disc is disposed in the cutting chamber, rotates about an axis, and has an axial surface facing the intake opening. A cutting member is fixed to the disc for revolution about the axis concurrent with rotation of the disc for reducing waste material. A cutting anvil is coupled to the housing adjacent to the intake opening and faces the axial surface of the disc for reducing waste material between the cutting anvil and the cutting member. A line shear element is attached to the housing, extends into the cutting chamber toward the axial surface of the disc, and is spaced from the cutting anvil for shearing lines caught by the rotating disc.

A electronic grinder includes a main body removably attached to a grinding and dispensing chamber. The top of the main body is sealed by an upper cab and the bottom of the chamber is sealed by an openable lower cap. The main chamber includes a motor connected to a magnetically attached removable blade. The blade extends into the chamber when the grinder is assembled. When the lower cap is closed, the blade grinds material placed in the chamber. When the lower cap is opened, the blade functions as a fan to dispense ground material out of the chamber. The grinder also includes a display, an electronic scale, and an accessory cigarette lighter.

A portable manual grinder has a driving section, a grinding section and a discharging section coaxially connected from top to bottom. The driving section has a drive shaft that drives a central axis of the grinding section. The drive shaft is connected to a gear set that increases the gear ratio to facilitate manual grinding. The grinding section comprises an upper grinding section and a lower grinding section that are coaxially disposed and mated together. The upper and lower grinding portions include corresponding blades extending therefrom. The bottom section of the lower grinding section has one or more holes in communication with the discharge section. The driving section and the upper grinding section are magnetically attracted and connected to each other and the upper grinding section and the lower grinding section are magnetically attracted and connected to each other.

A food processor may include: a base; a container including an accommodation tub installed on an upper surface of the base and accommodating a processing target, a handle support part laterally protruding from a side surface of the accommodation tub, and a handle extending upwards or downwards from the handle support part; a lower enclosure installed on the upper surface of the base to surround a lower portion of the accommodation tub; and an upper enclosure positioned in a coupled state and a released state with respect to the lower enclosure and cooperatively supporting the handle support part together with the lower enclosure to suppress shaking of the container.

An attachment (60) for a spout (140) of a food processing apparatus (10), including a housing (70) with a liquid inlet (80), a front face (160), and a liquid outlet (100). The housing defines a posterior cavity (110) that removably receives the spout and position the liquid inlet next to the spout. The attachment also includes a drip-stop flap (150) which is attached to and covers the front face of the housing. The drip-stop flap reversibly pivots about a horizontal pivot axis between a closed position where the liquid outlet is blocked by a sealing element on the flap, and an open position where the liquid outlet is exposed.

A vacuum blender can crush foods, such as vegetables and fruits, in a vacuum state and preserve the foods in the vacuum state. Noise can be reduced because foods are put into an accommodation member and the foods accommodated in the accommodation member are blended in a state in which the accommodation member is covered by a cover member. Further, because a first chamber part is formed in the interior of the accommodation member and a first check valve is mounted and a second chamber part that is an empty space is formed between the accommodation member and the cover member, the first chamber part, in which the foods are accommodated, is vacuumed while the first check valve is automatically opened if the second chamber part is vacuumed without using a separate hose connected to the first chamber part.

A paper shredder includes a chassis on which an automatic paper feeding opening is defined, a paper shredding mechanism, a paper separating mechanism located adjacent to the automatic paper feeding opening, and a paper pickup mechanism located between the paper separating mechanism and paper shredding mechanism. The paper separating mechanism includes a first paper supporting board on which a fastening mechanism is provided and a paper separating board cooperating with the fastening mechanism. The paper pickup mechanism includes a holding bracket, a paper pickup roller axe, a plurality of paper pickup rollers sleeved on the axe, a second paper supporting board located below the plurality of rollers and secured onto the second paper supporting board, and a third paper supporting board located above a distal end of the second paper supporting board and connected with the paper separating mechanism.

Methods and systems for reducing an average particle size of blackwater solids is disclosed. A vessel is configured to receive a blackwater stream through a one-way inlet. The one-way inlet is configured to allow the blackwater stream into the vessel and prevent backflow. The blackwater stream contains blackwater solids and water. A device in a bottom portion of the vessel is configured to receive the blackwater and comminute the blackwater solids. A recirculating pump is configured to recirculate the blackwater stream under pressure through the device until the average particle size of the blackwater solids is reduced below a size threshold, resulting in a sized blackwater stream.
