ABSTRACT:
An apparatus for dispensing a hydratable material includes a source of the hydratable material to be dispensed, including a container and a metering unit. A continuous-flow first mixer has a truncated conical mixing chamber with an open upper end and an open lower end of smaller diameter than the upper end. The upper end is disposed to receive the flow from the metering unit and the lower end delivers a flow of a mixture of the hydratable material and water. A plurality of water inlet openings at an upper end of an inner surface of the conical mixing chamber introduce water tangentially along the inner circumference of the cone to create a vortex effect within the cone. A continuous-flow second mixer is positioned directly adjacent to and below the first mixer and receives the flow of mixture from the first mixer. The second mixer includes at least one outlet opening of a size less than a preselected size, an impeller disposed to mix the mixture of hydratable material and water with high energy and force the mixture toward the outlet opening, and a motor that turns the impeller to have a tip speed of at least about 25 feet per second.
