A waste treatment apparatus includes: a body having a spherical shape and configured to accommodate a waste therein; and a stirring unit configured to stir the waste accommodated in the body. The stirring unit includes: a main shaft horizontally and rotatably disposed at a center portion in the inside of the body; a plurality of main shaft stirring blades having a flat plate shape, the plurality of main shaft stirring blades mounted on a surface of the main shaft; a plurality of support rods assembled to the main shaft at a predetermined interval, the plurality of support rods extending perpendicularly toward an inner peripheral surface of the body; and a plurality of stirring blades each having a rectangular flat plate shape, the plurality of stirring blades being mounted on distal ends of the plurality of support rods on an inner peripheral surface side of the body.

A frozen product dispensing apparatus (20) comprises a refrigeration system (50) and a freezing cylinder (52). A source (42) of the product or precursors of the product is coupled to an inlet (124) of the freezing cylinder. An outlet valve (38) has an open condition for discharging product from the freezing cylinder. A beater assembly (53) is within the freezing cylinder and has an axis (502) and an outer helical member (152). A motor (62) is coupled to the beater assembly for driving rotation of the beater assembly about the axis so that when driving said rotation in a first direction (530), the outer helical member drives product (540) toward the outlet valve. The beater further comprises an inner helical member (200; 300; 400) within the outer helical member.

A continuous extrusion kneader comprising a first supply section for supplying a solid electrolyte, a first kneading section for kneading a material supplied from the first supply section to provide an intermediate mixture, a second supply section for supplying an electrode active material to the intermediate mixture, and a second kneading section for kneading the intermediate mixture and the material supplied from the second supply section, wherein the first kneading section comprises a forward kneading section for kneading the material supplied from the first supply section and conveying the material downstream, and a reverse kneading section for kneading the material supplied from the forward kneading section and applying a force in the upstream direction.

Apparatus and methods for food production including a food preconditioner (228) operable to heat and partially pre-cook food ingredients, and a twin screw extruder (20) operable to further cook the preconditioned ingredients to create final food products. The extruder (20) includes a pair of hollow core extrusion screws (50, 52, 124, 126, 190) having elongated hollow core shafts (54, 128, 130, 192) equipped with helical fighting (56, 132, 134, 194) along the lengths thereof. The fighting (132, 134, 194) is also of hollow construction which communicates with the hollow core shafts (54, 128, 130, 192). The flighting (56, 132, 134, 194) also includes forward, reverse pitch sections (64, 162, 216). The extrusion screws (50, 52, 124, 126, 190) are designed to impart high levels of thermal energy into materials being processed in the extruders (20), without adding additional moisture.

An extruder screw for plasticizing at least one plastic or plastic mixture, including a melting zone, a shaft zone and a mixing zone arranged between the melting zone and the shaft zone, wherein a conveying flight is formed in the melting zone and in the shaft zone, which extends helically along a longitudinal axis of the screw, wherein a conveying flight of the melting zone ends at an end of the melting zone towards the mixing zone and a conveying flight of the shaft zone begins at an end towards the mixing zone. A flight depth of the melting zone continuously decreases along the longitudinal axis of the screw to the mixing zone. Further, an extrusion device having the extruder screw and to a method for plasticizing at least one plastic or plastic mixture.

A stirring device for a powder tank of an apparatus for manufacturing a three-dimensional object. The stirring device is configured to rotate within the powder tank about an axis of rotation, and comprises a base plate and a strut. The strut extends from the base plate and is arranged to extend into the powder tank forming an obtuse angle with the outer edge of the base plate
