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.
