Abstract: Described herein includes sample liquid purification apparatus, systems, and techniques of use. The purification apparatus generally can operate to reduce a temperature of a precursor liquid within a beverage machine or appliance. For example, a thermally conductive body can define a heat sink having a tortuous path for propagation of the precursor therethough, facilitating temperature reduction. The purification apparatus can further generally operate to sanitize or otherwise reduce a level of contaminants in the precursor liquid. For example, an energy source, such as a light emitting diode, can be arranged or integrated with the thermally conductive body to emit ultraviolet radiation toward the precursor liquid within the thermally conductive body.

Abstract: A vortex flow inducer has inducer body with an interior end, an outer end and a length extending there between, and a longitudinal axis extending between the interior and the outer ends. A flow passage extends between the interior and outer ends of the inducer body. The flow passage has an inlet at the outer end and an exit at the interior end. The flow passage is swept laterally toward a side of the inducer body in a direction from the outer end toward the interior end such that the exit is laterally offset from the longitudinal axis.

The buoy (28) can have a specific gravity corresponding to a selected fraction such that the buoy floats on a surface of the selected fraction, wherein the fractions floating on the selected fraction can be withdrawn through the orifice (32).

Abstract: An inclined belt conveyor capable of mixing particulate material, such as agricultural seed or fertilizer. Inserting a plurality of mixing baffles into the stream of the particulate material induces a backflow of the particulate material. In the case of wet, freshly treated plant seed, this backflow causes a mixing, polishing, and drying of the plant seed. The mixing distributes the seed treatment into an even coat by rubbing the individual seeds of the seed flow stream together. The inclined belt conveyor may also be used to blend multiple varieties or types of particulate material. The mixing baffles are oriented to induce backflow and sideways lateral movement and may incorporate a passage to allow increase particulate material flow rate. The mixing baffles can selectively deploy between an angle of 20 degrees to 70 degrees to enable the mixing inclined belt conveyor to have a transfer-speed-maximizing mode and a mixing mode.
