Each blade has an outer geometrical plane parallel to a center axis, perpendicular to a radius of the propeller, intersecting both a leading edge and a trailing edge of the blade, and an inner geometrical plane parallel to the outer geometrical plane and tangent to the hub. Each intermediate geometrical plane of the blade has an arc-shaped cross section extending between the leading edge and the trailing edge, and a chord extending between the leading edge and the trailing edge. An angle between the chord and a radial plane of the propeller is 25-45 degrees in each intermediate geometrical plane. The ratio between an arc-height between the chord and the thrust side surface, and the length of the chord, is 0.08-0.15 in each intermediate geometrical plane.

A multi-layered micro-channel mixer includes a base plate and a cover plate. Two inlet fluid reservoirs, two inlet channels, two groups of fluid distribution channel networks, two groups of process fluid channels, an impinging stream mixing chamber, a fluid mixing intensification channel and an outlet buffer reservoir are provided on the base plate. Two fluids are fed into the two inlet fluid reservoirs, respectively. The fluids then flow into the process fluid channels via the inlet channels and the multi-stage fluid distribution channel networks, respectively. Then the two fluid streams ejected from the opposing process fluid channels impinges upon each other in the impinging stream mixing chamber. The mixed fluid is subjected to vortex or secondary flow generated by the baffles or the internals in the impinging stream mixing chamber and fluid mixing intensification channel, and finally the mixed fluid is discharged through the outlet buffer reservoir.

A conveyor having a conveyance structure, mixing components, belt, and gas manifold. The gas manifold disposed within or on an exterior portion of the structure. The gas manifold having one or more manifold outlet ports to dry, condition, or treat a metered stream of seed within the conveyor. The manifold may be operably connected to a recirculating air system providing the vacuum source and pressurized air source of atmospheric or conditioned air. A filter and vacuum port may extract debris or humidity from the metered stream of seed within the conveyor. A plurality of mixing baffles may be longitudinally spaced apart through the conveyor in a laterally alternating manner to mix the metered stream of seed. The conveyor may be used to transfer, mix, dry, condition and treat the metered stream of seed between multiple stages of treatment.

An agitator is capable of more efficiently applying a shear force to a treatment target fluid through the action of an intermittent jet flow. The agitator includes a rotor which includes blade, and a screen concentric therewith, the rotation of at least the rotor causing a treatment target fluid to pass through slits in the screen to become an intermittent get stream, which is discharged from inside the screen to the outside thereof, wherein the agitator is characterized in that: the screen has a cylindrical shape with a circular cross section; openings of the slits provided in an inner surface of the screen constitute flow intake openings; openings of the slits provided in an outer surface of the screen constitute flow discharge openings; spaces between the flow intake openings and the flow discharge openings constitute slit space; and the circumferential-directional width (So) of the flow discharge openings and the circumferential-directional width (Si) of the flow intake openings are greater than the circumferential-directional width (Sm) of the slit spaces.

A mixing paddle specifically designed to produce pastry dough is disclosed. The mixing paddle is comprised of a shaft, a rim, a first plurality of parallel blades and a second plurality of parallel blades. The shaft bisects the rim, creating a first side and a second side. The first plurality of parallel blades is perpendicular to the second plurality of parallel blades.

A vacuum deaerator degasses material to be processed by placing a rotating rotor with a screen in a vacuum vessel, introducing a liquid material to be processed into the rotor from the interior thereof and causing the liquid to pass through the screen to refine the same. The vacuum deaerator is characterized in that: the screen is a cylinder with a circular cross-section and is in the form of a porous plate in which a plurality of through holes are opened in the radial direction of the cylindrical screen; and the screen is provided such that the area of inflow openings is greater than the area of outflow openings, where the inflow openings are openings of a plurality of penetration portions provided on the inner wall face of the screen and the outflow openings are openings of the plurality of penetration portions provided on the outer wall dace of the screen.
