A blender includes a container body in which food is accommodated, a main body provided underneath the container body and supporting the container body, a container lid detachably mounted on an upper surface of the container body and opening and closing the top of the container body, and a blade assembly of which a blade chops the food inside the container body into small pieces. O more concave grooves in a shape of “” are formed in one end portion of the blade.

Plastic sheet elements (19) having a size and deformation suitable for use as a filling material in pillows, duvets and the like are manufactured by feeding one or more plastic sheets to a shredding apparatus (6) which has a rotating drum (9). Loosely hanging knives (12) are mounted (11) near an outermost edge of the drum (9), and are pivoted outwards during rotation to thereby cut, deform and twist the sheet to form “curly” elements (19), which are sucked out through openings (14) in a screen (8) located below the drum (9). By adjusting the feeding of the sheet (4), the rotation of the drum (9) and the magnitude of the negative pressure, various sizes and configurations of cut individual sheet elements (19) are produced.

A blade system for device for recycling mixed plastic is disclosed. Furthermore, a device and a method for recycling unidentified, unclean, and unsorted mixed plastic into reusable plastic mixture is disclose. The present solution allows the recycling of mixed plastic waste outdoors, both in warm and cold climate conditions. In the course recycling mixed plastic waste the mixed plastic waste is taken to a melting temperature, at which the mixed plastic waste is mixed in a molten state, and the organic and bacterial material is destroyed during the thermal processing. After the melting, mixing and thermal processing of the mixed plastic waste, the compaction process of the molten mixed plastic waste is performed. Volume compacting is performed, and the mass of mixed plastic waste in a molten state is rapidly cooled down, crushed, after-cooled and homogenized.

A cutting apparatus and an associated method for slitting a tobacco sheet material into cut pieces used to form smoking articles are provided. The cutting apparatus includes a rotatable cutter assembly having a drum member configured to rotate about an axis defined thereby. The cutter assembly includes a plurality of knife members disposed about the periphery of the drum member and extending radially therefrom. A fixed counter-knife assembly is disposed adjacent to the periphery of the drum member and is configured to interact with the rotatable cutter assembly during rotation thereof about the axis. The counter-knife assembly includes a ledger member having a plurality of cutting insert members removably engaged therewith. The cutting insert members are configured to interact with the knife members during rotation of the cutter assembly with respect to the counter-knife assembly so as to slit the tobacco sheet material received therebetween into cut pieces.

A tooth and a toothholder for a mulching apparatus. The tooth includes a body, a cutting element mounted to the body, and a mounting element projecting from the body. The toothholder includes a mounting recess for receiving the mounting element. The mounting element engages the mounting recess to prevent rotation of the tooth relative to the toothholder. The mounting element may be shaped to engage with the toothholder to prevent rotation of the tooth relative to the toothholder. The mounting element may include a plurality of outer engagement surfaces. The plurality of outer engagement surfaces may define an exterior profile of the mounting element that is polygonal in shape.
