A mixing unit includes a mixing body having mixing elements that are stacked in a stacking direction and that extend in an extending direction in which the extending direction is perpendicular to the stacking direction. The mixing elements have a plurality of through holes to form a flow path therein, and are arranged such that part or all of the through holes in one of the mixing elements communicate with through holes in the adjacent mixing elements to allow fluid to be passed in the extending direction in which the mixing elements extend. The mixing unit may be employed in an agitation impeller or an adhesive dispensing unit.

An apparatus is equipped with first and second rotary shaft 3, 4 and a plurality of disks 40, 50 provided upright at equal intervals on the respective rotary shaft. The disks are heated or cooled from the inside, and a raw material is heated or cooled by bringing it into contact with the disk surfaces. Scraper members 45, 45 and 55, 55 that enter between the surfaces of the facing adjacent disks to scrape the raw material are fixed to each of the disks 40, 50. The first and second rotary shafts 3, 4 are rotated at unequal speeds such that the scraper members approach the facing disk surfaces with trajectories drawn thereon varying, so that the raw material that has adhered to the disk surfaces can be effectively scraped off.

A machine (1) for homogenising a food substance has: a container (10) with a side wall (11) and a bottom wall (12) delimiting a cavity (10); an impeller (30) with an impelling member (31) forming an impelling surface (31,31,31) that is drivable in rotation (r) about a central axial direction (30) of the impelling surface (31,31,31) for imparting a mechanical effect to the food substance; and a module (20) which has a housing means (22) that contains an inner chamber (22,22a) and that delimits a seat (21) for the container (10), the chamber (22,22a) containing an electric motor (24). The electric motor (24) has an output drive axis (24) with a driver device (24) configured to drive a follower device (35) of the impeller (30). The driver device (24) and the follower device (35) are magnetically coupled through a sidewall (11) and/or bottom wall (12) of the container (10). The driver device (24) comprises a ferromagnetic or magnetic field-generating element (24a) that is arranged to be magnetically coupled to a corresponding ferromagnetic or magnetic field-generating element (36) of the follower device (35). The follower device (35) extends over a predominant part of the bottom wall (12) of the container (10) or across a substantial part of the wall (12) along a diameter thereof. The driver device (24) extends over a predominant part of a bottom part of the seat (21) or across a substantial part of the bottom part of the seat (21) along a diameter thereof. The ferromagnetic and magnetic field generating elements (24a,36) are positioned at extremal or peripheral parts of the follower device (35) and of the driver device (24).

An emulsion system is provided. The system includes a shaft that supports a plurality of cutting assemblies and plates in alternating order, wherein the cutting assembly rotates with respect to an in close proximity to the plate. The plurality of cutting plates each on their circumferential edge have an identification system to memorialize the diameter of the emulsion holes.

A vertically moving horizontal mixer assembly which includes a tank having an axis. A stator and blade support assembly is movable parallel to the tank axis. At least one rotatable blade substantially perpendicular to the tank axis is moveable parallel to the tank axis. The rotating blade may be a flat circular disk with raised tooth edges perpendicular to the disk around the circumference of the blade. An optional stator also directs and encourages movement and mixing of solids with liquids.

The present invention relates to an apparatus, which can be part of a pre-treatment system in a plant for the production of fuels, e. g. bio-ethanol, derived from plant biomass, e. g. first generation crops, such as grain, sugarcane and corn or second generation crops such as lignocellulosic biomass. The invention relates to an apparatus for processing, such as fluffing and mixing, at least two media, such as a solid, e. g. biomass, and a fluid, e. g. steam, so as to rendering the first medium susceptible to efficient receiving of energy and/or mass which is provided by localized release of the second medium. Although the description of the present invention focuses on biomass, it is envisaged that the invention is generally applicable to control the mixing of at least two media by crossing their stream of while dispersing at least one of them.

An agitation device includes: an agitation member including a disk of substantially plate shape provided rotatably about a vertical axis in a passage through which liquid and gas flow; and a motor configured to rotationally drive the agitation member. The disk is provided with a plurality of openings to shear the liquid and the gas.
