Abstract
Apparatus for the continuous mixing and homogenization of powdered substances, such as powdered milk, with water or other beverages, comprises a hopper (1) with vibrating sieve (2) and a screw (3) situated at the base of the hopper and actuated with variable angular velocity by a motor (4). The powdered substance is transported by the screw to a nozzle (5) opening into a converging-diverging chamber (6) which functions as Venturi tube. The liquid enters from an injection conduit (7) and is mixed with the powder and the mixture is carried to a homogenization turbine (9, 10) from which it is discharged completely homogenized.
Claims6
Apparatus for the continuous mixing and homogenization of powdered substances with liquid substances, comprising a hopper (1) adapted to contain the powdered substance;
- a screw (3) situated at the base of the hopper, a housing surrounding said screw said housing having a terminal construction followed by a converging-diverging chamber functioning as a venturi, a motor (4), for actuating the screw such that the powdered substance is transported to a said terminal constriction (5) to hold back the powder flowing into said converging-diverging chamber (6);
- an injector conduit, an annular nozzle (16) from which liquid, introduced under pressure from said injection conduit (7) is discharged at great velocity in an annular stream into said venturi;
- a homogenization turbine, comprising a rotor with a plurality of rings (9') having channelling (8') to which rotor the powdered mixture plus liquid is fed from said venturi, and a stationary diffuser (10) having rings (10') interfingering with those of the rotor and having channelling (15);
- said rotor terminating in a discharge conduit (14) for the homogenized mixture.
