Abstract

A powder dispensing device is provided including a housing; a hopper sized and shaped to engage the housing to form a reservoir; a first barrel in fluid communication with the reservoir via one or more first apertures and having a first internal diameter; a second barrel in fluid communication with the reservoir via one or more second apertures and having a second internal diameter, wherein the first internal diameter is greater than the second internal diameter; at least one motor coupled to the first barrel and the second barrel, the at least one motor configured to rotate the first barrel and the second barrel; a scale electrically coupled to a scale plate, the scale plate disposed on the housing and below the first barrel and the second 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.

Claims (47)

1. A powder dispensing device comprising:

a housing;

a hopper configured to be seated in a reservoir of the housing and contain powder;

a first barrel in fluid communication with the reservoir;

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 an underside of the housing and defining a drain hole, the drain member 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 to establish an open path to allow powder to flow from the hopper and from the powder dispensing device;

the drain assembly configured to provide an indication that the drain member is in the second position;

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.

2. The powder dispensing device of claim 1 , further comprising a fixed plate disposed between the reservoir and the drain member, the fixed plate blocking the drain hole when the drain member is rotated to the first position, the drain hole in fluid communication with the reservoir when the drain disk is rotated to the second position.

3. The powder dispensing device of claim 1 , further comprising a sensor transmitting a signal representative of a position of the drain member.

4. The powder dispensing device of claim 3 , wherein the signal representative of the position of the drain member is an audible signal.

5. The powder dispensing device of claim 1 wherein the user input comprises a target weight, the at least one motor rotating the first barrel until the target weight is measured by the scale.

6. The powder dispensing device of claim 1 wherein the first barrel is disposed at a downward angle from the reservoir toward the scale plate.

7. A powder dispensing device comprising:

a housing;

a hopper configured to be seated in a reservoir of the housing and contain powder;

a first barrel in fluid communication with the reservoir;

a second barrel in fluid communication with the reservoir;

at least one motor coupled to the first barrel and the second barrel, the at least one motor configured to rotate the first barrel and the second 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 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 to establish an open path to allow powder to flow from the hopper and from the powder dispensing device;

the drain assembly configured to provide an indication that the drain member is in the second position;

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.

8. The powder dispensing device of claim 7 , further comprising a fixed plate disposed between the reservoir and the drain member, the fixed plate blocking the drain hole when the drain member is rotated to the first position, the drain hole in fluid communication with the reservoir when the drain disk is rotated to the second position.

9. The powder dispensing device of claim 7 , further comprising a sensor transmitting a signal representative of a position of the drain member.

10. The powder dispensing device of claim 9 , wherein the signal representative of the position of the drain member is an audible signal.

11. The powder dispensing device of claim 7 wherein the user input comprises a target weight, the at least one motor rotating the first barrel until the target weight is measured by the scale.

12. The powder dispensing device of claim 7 wherein the first barrel and the second barrel are disposed at a downward angle from the reservoir toward the scale plate.

13. The powder dispenser device of claim 7 , further comprising a second motor configured to move the second barrel.

14. The powder dispensing device of claim 13 , wherein the user input comprises a target weight, wherein the at least one motor moves the first barrel until a first portion of the target weight is measured by the scale and the second motor moves the second barrel until a second portion of the target weight is measured by the scale.

15. A powder dispensing device comprising:

a housing;

a hopper configured to be seated in a reservoir of the housing and contain powder;

a first barrel in fluid communication with the reservoir;

a second barrel in fluid communication with the reservoir;

a first motor coupled to the first barrel, the first motor configured to move the first barrel to dispense powder from the reservoir;

a second motor coupled to the second barrel, the second motor configured to move the second 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 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 to establish an open path to allow powder to flow from the hopper and from the powder dispensing device;

the drain assembly configured to provide an indication that the drain member is in the second position;

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.

16. The powder dispensing device of claim 15 further comprising a fixed plate disposed between the reservoir and the drain member, the fixed plate blocking the drain hole when the drain member is rotated to the first position, the drain hole in fluid communication with the reservoir when the drain disk is rotated to the second position.

17. The powder dispensing device of claim 15 , further comprising a sensor transmitting a signal representative of a position of the drain member.

18. The powder dispensing device of claim 17 wherein the signal representative of the position of the drain member is an audible signal.

19. The powder dispensing device of claim 15 wherein the user input comprises a target weight, the at least one motor rotating the first barrel until the target weight is measured by the scale.

20. The powder dispensing device of claim 15 wherein the first barrel and the second barrel are disposed at a downward angle from the reservoir toward the scale plate.
