Dual-barrel powder dispenser

A powder dispensing device comprising:

• a housing;
• a hopper defining a reservoir therein;
• a first barrel in fluid communication with the reservoir;
• a second barrel in fluid communication with the reservoir, the second barrel having a diameter less than a diameter of the first barrel;
• at least one motor coupled to the first barrel, the at least one motor configured to rotate the first barrel to dispense powder from the reservoir;
• a drain assembly comprising a rotatable drain member coupled to the housing and defining a drain hole, the drain member being rotatable between a first position wherein the drain hole is blocked from the reservoir and a second position wherein the drain hole is in communication with the reservoir;
• a scale electrically coupled to a scale plate, the scale plate disposed below the first barrel;
• and
• a user interface in electrical communication with the at least one motor and the scale, the user interface configured to receive a user-input.
