A slurry distributor for use in a continuous manufacturing process includes an inlet opening and a shaped duct adapted to receive a flow of slurry provided at the inlet opening. The shaped duct has a parabolic guide surface adapted to redirect the flow of slurry. An outlet opening in fluid communication with the shaped duct is adapted to discharge the flow of slurry from the slurry distributor.

1. A gypsum slurry mixing and dispensing assembly, comprising: a mixer adapted to agitate water and calcined gypsum to form an aqueous calcined gypsum slurry;a slurry distributor in fluid communication with the mixer, the slurry distributor comprising: an entry segment defining an inlet opening and adapted to receive the flow of aqueous calcined gypsum slurry,a shaped duct in fluid communication with the inlet opening, andan outlet defining an outlet opening in fluid communication with the shaped duct and adapted to discharge the flow of aqueous calcined gypsum slurry from the slurry distributor,wherein the shaped duct includes a parabolic guide surface adapted to redirect the flow of aqueous calcined gypsum slurry moving from the inlet opening through the shaped duct to the outlet opening from an inlet direction to an outlet direction by a change in direction angle within a range of about forty-five degrees to about one hundred fifty degrees;a delivery conduit disposed between and in fluid communication with the mixer and the slurry distributor;a flow-modifying element associated with the delivery conduit to control the flow of the aqueous calcined gypsum slurry;an aqueous foam supply conduit in fluid communication with at least one of the mixer and the delivery conduit. 2. The gypsum slurry mixing and dispensing assembly of claim 1, further comprising a second inlet opening in fluid communication with the shaped duct of the slurry distributor, the second inlet in fluid communication with the mixer and adapted to receive a second flow of aqueous calcined gypsum slurry therefrom. 3. The gypsum slurry mixing and dispensing assembly of claim 2, wherein the parabolic guide surface of the slurry distributor is at least partially defined by an outer curved wall of the shaped duct, the shaped duct of the slurry distributor is further defined by a slanted wall extending at an obtuse angle relative to an outlet plane defined by the outlet opening, and the second inlet is defined in the slanted wall. 4. The gypsum slurry mixing and dispensing assembly of claim 1, wherein the change in direction angle is about ninety degrees. 5. The gypsum slurry mixing and dispensing assembly of claim 1, wherein the width of the outlet opening of the slurry distributor extends along a transverse axis and at least a portion of the parabolic guide surface is aligned with the width of the outlet opening along the transverse axis. 6. The gypsum slurry mixing and dispensing assembly of claim 1, wherein the shaped duct of the slurry distributor has a generally rectangular cross section and a generally curved outer wall that defines the parabolic guide surface. 7. The gypsum slurry mixing and dispensing assembly of claim 6, wherein the entry segment of the slurry distributor is generally cylindrical and further comprising: a round-to-rectangular cross section transition segment disposed between the entry segment and the shaped duct. 8. The gypsum slurry mixing and dispensing assembly of claim 1, wherein the parabolic guide surface of the slurry distributor is at least partially defined by an outer curved wall of the shaped duct. 9. The gypsum slurry mixing and dispensing assembly of claim 8, wherein the shaped duct of the slurry distributor is further defined by a slanted wall extending at an obtuse angle relative to an outlet plane defined by the outlet opening and in opposing relationship to the outer curved wall. 10. The gypsum slurry mixing and dispensing assembly of claim 1, further comprising: a profiling system adapted to locally vary the shape of the outlet opening of the slurry distributor. 11. The gypsum slurry mixing and dispensing assembly of claim 1, wherein the shaped duct of the slurry distributor has a cross sectional flow area that increases in a direction from the inlet opening toward the outlet opening. 12. The gypsum slurry mixing and dispensing assembly of claim 11, wherein a cross-sectional flow area of the outlet opening of the slurry distributor is in a range from greater than a cross-sectional flow area of the inlet opening of the slurry distributor to about 400% of the cross-sectional flow area of the inlet opening.
