A hands free frozen drink mixer system is a frozen drink mixing system of the immersion type that enables the user to automatically and hands-free blend ingredients for a frozen drink, add flavorings while blending, and automatically shut off the blender after a programmed interval of time. The hands free frozen drink mixer system may have a mixer assembly having an elevated motor supported by a back stand that integrally connects with a base having a drip basin and removable rack. A mixer shaft having a rotary blade assembly extends vertically downward from the front bottom side of the motor, and a canister holder that is adjustable in height via a vertical track holds a mixing canister. The canister is positioned over the base which has a removable drip tray.

Provided is a continuous reaction apparatus which can precisely control the path of flow of the liquid reaction mixture in the reaction vessel. Further, provided is a continuous reaction apparatus which can efficiently mix the liquid reaction mixture in the reaction vessel. The continuous reaction apparatus comprises a plurality of mixing vessel units and a plurality of partition units. These units are connected in the state of being alternately stacked on one another. Each mixing vessel unit has an agitating blade disposed in the inner space thereof. The relationship between the inner diameter D1 of the mixing vessel unit, the height H of the mixing vessel unit, and the outer diameter d1 of the agitating blade satisfies the formula (1): 10(D1/H)1.5, and the formula (2): 0.99(d1/D1)0.7. The agitating blade is a circular disc-type agitating blade.

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).

The invention discloses an agitation device comprising an impeller, an agitating shaft and a power device. The impeller includes a disc, a hub and concave blades. Each blade consists of a concave surface which extends radially and has an annular sector-like shape, the projections of the upper and lower portions of the blade in the horizontal plane are two annular sectors, and the radian of the annular sector obtained by the projection of the upper portion is larger than that of the lower portion, and the annular sector-like shape and the rotation direction of blades are the same, so that each portion of the blades directly faces an incoming flow, the utilization efficiency of blades is increased and the impeller has low energy consumption and high gas-liquid dispersion efficiency. The device is efficient and energy-saving, has low power consumption, high mixing performance and high gas holdup and mass transfer performance.

Turning motion of gypsum slurry spouting onto a sheet of paper for a gypsum board liner is restricted for preventing maldistribution, deviation or irregular dispersion from occurring in the density distribution of the slurry on the sheet of paper. A mixing and stirring device for gypsum slurry has a circular casing forming a mixing area, a rotary disc positioned in the casing, and a tubular passage for feeding the slurry onto the sheet of paper for the gypsum board liner. A chute has a fluid passage portion with its cross section being non-axisymmetric with respect to a center axis of the tubular passage, or a fluid passage portion varying a position of the center axis of the tubular passage by a change or lateralization of the cross section of fluid passage.

A continuous kneading device is provided with an upper trunk (1) to which a powder supply tube (3) through which quantified powder is supplied is connected and in which the powder is blended with a fluid, and a lower trunk (2) concentrically connected to the bottom of the upper trunk (1). The continuous kneading device continuously kneads the powder and the fluid by a first rotating kneading plate (10) built into the upper trunk (1) and a second rotating kneading plate (11) built into the lower trunk (2), wherein surfaces of the base metals of the first and second rotating kneading plates (10, 11) are covered with a coating material (50) for reducing friction when the powder and the fluid are kneaded together.
