The assembly also includes a vacuum pump 150 powered by an electrical motor 160, a particle filter 200 to filter out particles upstream of the vacuum pump and a drum arrangement which includes a collector drum 170 configured to rotate about an axis to mix its contents to form a slurry and it discharge the contents when in the discharge position.

A rotating drum apparatus for the mixing and processing of materials, the rotating drum apparatus comprising: a rotating drum (12) arranged with the length of the drum and the axis of rotation of the drum extending along the horizontal; an inlet at a first point on the drum (12) for receiving materials prior to mixing and/or processing; a screw (14) within the drum (12) for mixing the materials whilst conveying them lengthwise along the drum (12), wherein the screw (14) includes a helical blade extending along the length of the drum (12) with the outer edge of the helical blade being fixed to the inner surface of the drum (12) such that material can be conveyed and mixed in separated volumes (16) between each turn of the screw blade (14); an outlet at a second point along the drum for discharge of materials after mixing and/or processing; and a plurality mixing devices (18) for promoting mixing of the material in each of the separated volumes (16) of material as the material is conveyed along the screw (14), wherein the plurality of mixing devices (18) are spaced apart along the blade of the screw (14), and wherein there is at least one mixing device (18) for each turn of the screw blade (14).

A flight assembly comprising a flight with a curved outer edge portion and a support supporting the flight at an acute angle with respect to a longitudinal axis of the flight assembly, wherein the curved outer edge portion when rotated about the longitudinal axis describes a cylinder. The flight assembly is configured to cooperate in a system for blending flowable solid materials, comprising a cylindrical drum body, a drum roller apparatus arranged support and rotate the cylindrical drum body at an angle of inclination and a flight assembly as previously described. Associated methods are also disclosed.

Apparatuses and methods based thereon are provided for mixing utilizing mixer inserts. A mixer insert may comprise an enclosing component adapted for application to an opening in a container to which the mixer insert is applied, to enclose a space in the container. The mixer insert may further comprise one or more mixing components, adapted to fit within the enclosed space when the enclosing component is applied to the opening in the container, with the one or more mixing components being configured to mix material placed within the enclosed space when the combination of the container and the mixer insert is subject to particular force or movement.

An improved blending apparatus for blending of wood strands in the manufacture of engineered wood products. The blending process is performed with a rotating blending drum with an internal offset spike/paddle roll. The spike/paddle roll is substantially parallel to the longitudinal axis of the drum, extends for some, all, or substantially all of the length of the drum, may rotate in either direction, and can rotate independently of or in conjunction with the rotation of the drum. The roll has a central cylinder or rod with a number of paddles, spikes, and/or tines, separately or in combinations, extending from the exterior. The paddles, spikes, and/or tines may extend at various angles and directions, including, but not limited to, substantially right angles. The paddles, spikes, and/or tines may be made of any suitable materials, including, and may be made of different materials. The rod may be driven by an external or internal motor or drive, or powered by the rotation of the drum itself.

An apparatus is provided which comprises a barrel having a substantially cylindrical configuration. The barrel comprises an exterior surface and defines an interior volume. A base unit comprises a drive motor being configured to rotate the barrel by interfacing with the exterior surface of the barrel. The barrel comprises a thermoelectric heat pump attached thereto and being controllable for at least one of transferring heat out of the interior volume and transferring heat into the interior volume.

A stirring container and a stirring apparatus are provided. The stirring container includes a barrel and a plurality of stirring paddles. The barrel is defined with an inner surface, an outer surface, and a center axis. The first opening and a second opening are located at two ends of the center axis; and the paddles are fixed on the inner surface of the barrel and extend from the first opening to the second opening and the extending directions thereof are skewed to the center axis. The stirring apparatus includes the aforesaid stirring container, a supporting structure and a rotation module. The supporting structure connects to the outer surface of the barrel to make the barrel rotatable and covers the second opening. The rotation module connects to the outer surface to rotate the stirring container. Thereby, the stirring container and the stirring apparatus can provide better stirring results.
