摘要:
A mixing apparatus and method mixes constituents of a feedstock in a vessel, utilizing a mixing blade assembly rotated within the vessel in forward and reverse directions. The feedstock engages walls of the vessel, and scraper blades are carried by the mixing blade assembly to scrape feedstock from the walls of the vessel and direct scraped feedstock to feedstock being circulated within the vessel during rotation of the mixing blade assembly in either the forward direction or the reverse direction. The scraper blades each include scraper edges and are coupled to the mixing blade assembly for pivotal movement in response to engagement with feedstock during mixing, so as to juxtapose one or the other of opposite scraper edges of each scraper blade with the vessel wall for scraping feedstock during rotation of the mixing blade assembly in both the forward and reverse directions.

An apparatus and method for mixing feedstock within a vessel wherein the feedstock is moved along a heat transfer surface within the vessel. A mixing blade assembly includes a mixing blade and at least one mixing blade support member moved within the vessel to sweep forward along a path of travel extending adjacent the heat transfer surface. Feedstock is circulated within the vessel by the mixing blade, and the mixing blade support member includes a mixing surface confronting the heat transfer surface. The mixing surface is spaced from the heat transfer surface and is configured such that feedstock material is squeezed between the mixing surface and the heat transfer surface so as to be subjected to mixing shear and heat transfer between the squeezed feedstock material and the heat transfer surface. A scraper blade is located on the mixing blade support member in position to trail behind a trailing face of the mixing blade support member and is engaged with the heat transfer surface during movement of the mixing blade support member along the path of travel so as to scrape feedstock material from the heat transfer surface and direct the squeezed feedstock material to the mixing blade to be mixed with the feedstock circulated within the vessel by the mixing blade.

A fluid-agitating tank assembly is disclosed. The tank assembly includes a tank filled with a fluid, and an agitator disposed in the tank so as to be at least partially immersed in the fluid and supported by the tank in a rotatable manner about an axis. The agitator includes a double helix disposed in an upper volume of the tank and adapted to act on the fluid to transform unidirectional rotation of the agitator about the axis into a bidirectional movement of the fluid in the tank towards bottom and top portions of the tank, and at least one rotary blade projecting transversally from the axis, disposed in a lower volume of the tank, and rotating about the axis to move the fluid towards at least one lateral outlet of the tank.

A viscoelastic liquid flow splitter includes a flow splitter body having a first bore including a first bore outlet and a first bore inlet, and a second bore including a second bore outlet and a second bore inlet. The bore inlets are substantially parallel to each other and the bore outlets diverge from each other at an angle. The flow splitter also includes a compression fitting having a first and a second tubular portion fluidically coupled to the first and second bore inlets where the tubular portions are configured to fluidically couple to a double barreled viscoelastic liquid dispensing syringe.

A spiral-type kneading machine for the preparation of flour-based mixtures comprises a non-rotating circular bowl and a spiral-shaped kneading tool rotatable inside the bowl. The spiral-shaped kneading tool has its axis substantially coincident with the axis of the bowl and occupies substantially the entire space contained within the bowl. The tool cooperates with a fixed member projecting upwardly from the bottom of the bowl and spaced from the central axis thereof.
