Abstract: A stirrer arrangement for an ice-cream or yogurt machine includes a motor shaft hub adapted for coupling at a shaft of a motor within a chilling container, and a stirring blade unit which includes a plurality of blade members radially and outwardly extended from the motor shaft hub. Each of the blade members has an inclined pushing surface, such that when the motor shaft hub is rotated at a stirring direction, the blade members are spun for creating a radial stirring vortex within the chilling container to outwardly, radially, and upwardly push liquid material from a bottom of the chilling container to a top thereof and to inwardly, radially, and downwardly suck the liquid material from the top of the chilling container to the bottom thereof.

Abstract: A fluid mixing apparatus for mixing a fluid in a circular container includes a circular lid for engaging the open top container. A shaft is rotatably positioned through the lid and is rotatable about a shaft axis. A mixer is attached to the shaft adjacent one end for rotating with the shaft in a plane perpendicular to the shaft axis. The mixer receives the shaft. The mixer has a fixed portion and a hinged portion hingedly connected to the fixed portion. An agitator is mounted to the shaft for agitating a fluid when the apparatus is mounted in a container.

Abstract: The present invention relates to an ablative thermolysis reactor (12) comprising a reaction vessel (20), and inlet (14) into the reaction vessel (20) for receiving feedstock, and an outlet from the reaction vessel (20) for discharging thermolysis product. Within the reaction vessel (20), is provided an ablative surface (20a) defining the periphery of a cylinder, and heating means (22) are arranged to heat the ablative surface (20a) to an elevated temperature. In addition at least one rotatable surface (28) having an axis of rotation coincident with the longitudinal axis of said cylinder. The rotatable surface (28) is provided relative to the ablative surface (20a) such that feedstock is pressed between a part of the rotatable surface (28) and said ablative surface (20a) and moved along the ablative surface (20a) by the rotatable surface (28), whereby to thermolyse said feedstock.

Abstract: The present invention relates to a high intensity blending apparatus, particularly for blending operations designed to cause additive materials to become affixed to the surface of base particles. The tool comprises a shank having riser members at each end, such risers being angled to the axis of the shank between 10 and 16 degrees and having regions toward the trailing edges that are thicker than regions near the leading edges.
