Disclosed is a fine bubble water generator including: a housing being configured with an inflow line on one end thereof where air and fluid enters and a discharge line on an opposite end where fine bubble water is discharged; a partition allowing the air and fluid entered into the inflow line to flow in zigzags inside the housing; and a fine bubble water generation cylinder unit, being inserted into a space formed by the partition, allowing the air and fluid to be induced to collide with a surface thereof having bumps formed thereon and on an inner circumferential surface of the housing or the partition, thereby refining air bubbles and fluid by frictional force caused by a flat surface and the partition.

A stand mixer 10 comprises a head unit 50 having a lower surface presenting, in operation, a downwardly-facing drive outlet for driving in rotation at least one tool suspended therefrom. The head unit is supported with the downwardly-facing drive outlet above a receiving location 30 for a mixing bowl 40. Driving means, including an electric motor 70 and associated transmission means for conveying rotary drive to the drive outlet, are provided. The mixer further comprises first 80 and second 90 coaxial driving outlets presented on an upper surface 52 of the head unit 50; the coaxial outlets 80, 90 run at different speeds and are driven from the motor 70 by means of an epicyclic gearbox 100. The motor 70 is housed in the support means 60 with its drive shaft 72 in substantial alignment with the coaxial drive outlets 80, 90.

A mixing segment for an extrusion apparatus comprises a shaft and a plurality of plow elements aligned along a helical path extending about a rotation axis of the shaft. Each plow element includes an outer peripheral arcuate ramp extending radially outwardly along the helical path from a root to an outer tip of the plow element. Methods of manufacturing a mixing segment and methods of manufacturing a honeycomb structure with an extrusion apparatus are also provided.

The present invention provides a method of preparing a lipid nanoparticle dispersion using a twin screw extruder. The inventive DNLF fluids are isotropic fluids which include greater than 25% lipophilic content in the form of lipidic nanoparticles dispersed in a continuous aqueous matrix with turbidity less than 375 nephelometric turbidity units (NTU).

A screw element which has an axially asymmetrical screw cross-sectional profile which has at least two construction points located within the screw cross-sectional profile is provided. The screw element is suitable for use in an extruder having two drive shafts which rotate in the same direction and at the same speed, in order to process or produce plastic masses as an extrudate. Also, an arrangement of two identical or different screw elements in an extruder having two drive shafts which rotate in the same direction and at the same speed is provided. An extruder which is equipped with two identical or different screw elements and has two drive shafts which rotate in the same direction and at the same speed is provided. Furthermore, the use of the screw element according to the invention for processing or producing plastic masses is provided.

An internal mixer includes a mixing chamber having a mixing room, a material input portion having an inner space, a hopper provided in the material input portion, an exhaust passage having an exhaust port provided in the material input portion, and a driving device that raises and lowers a weight. The driving device can stop the weight at a lower position where the weight having entered the upper opening of the mixing room can press the material to be kneaded from above and an exhaust adjustment position where the weight closes a part of the exhaust port. When the weight is at the lower position, a gap is formed between the weight and the peripheral edge of the mixing chamber defining the upper opening.
