Infant formula device
View Patent ↗An apparatus is provided for accurately dispensing a powder such as powdered infant formula into a container, and pasteurizing and reconstituting the powdered formula while completely mixing the formula in the container. The apparatus includes a hopper assembly for storing powder, a dosing assembly for measuring and dispensing powder from a receptacle into the container, a dilution assembly and a mixing assembly for obtaining accurately and completely mixed formula from the dispensed powder. The hopper is shaped to promote powder bridging, and the resulting powder bridge is used in combination with the dosing assembly to provide a predetermined amount of powder using a single mechanical valve that is isolated from the powder. The mixing assembly mixes the contents of the container while holding the bottle at a fixed angle relative to the vertical. A method of providing pasteurized infant formula from an infant formula powder is also disclosed.
1. An apparatus for preparing within a container a reconstituted beverage from a powder, the apparatus comprising:
a receptacle configured to contain the powder;
a measuring device configured to receive the powder from the receptacle and dispense the powder into the container;
a liquid supply configured to dispense liquid into the container;
a mixing device configured to mix contents of the container while supporting the container such that a closed base end of the container is disposed at an angle relative to a horizontal angle; and
a vibrator configured to vibrate the receptacle to dispense the powder from the receptacle into the measuring device.
2. The apparatus of claim 1 , wherein the measuring device includes:
a tube having a first end connected to an outlet of the receptacle, and an open second end opposed to the first end; and
the apparatus further comprises a valve disposed between the first end and the open second end, the valve configured to control powder flow from the open second end.
3. The apparatus of claim 2 , wherein a cross-sectional dimension of the tube is determined based on properties of the powder to be dispensed.
4. The apparatus of claim 2 , wherein an axial position of the valve relative to a longitudinal axis of the tube is adjustable, and wherein the axial position is determined based on an amount of the powder to be dispensed.
5. The apparatus of claim 2 , wherein the valve is configured to selectively prevent the powder from passing through the open second end of the tube.
6. The apparatus of claim 2 , wherein the valve is configured to move a sidewall of the tube between a first tube sidewall position in which the powder can pass through the tube and a second tube sidewall position in which the powder is prevented from passing through the tube.
7. The apparatus of claim 1 , wherein the receptacle comprises:
an open receptacle first end having a first dimension;
an open receptacle second end opposed to the open receptacle first end, the open receptacle second end having a second dimension; and
a receptacle sidewall connecting the open receptacle first end and the open receptacle second end, a portion of the receptacle sidewall being angled so as to converge from the open receptacle first end to the open receptacle second end, the portion having an angle configured to cause powder bridging at or above the open receptacle second end.
8. The apparatus of claim 1 , wherein the receptacle is a pre-filled and sealed disposable cartridge.
9. The apparatus of claim 1 , wherein the liquid supply includes a first supply tube and a second supply tube, the first supply tube and the second supply tube arranged so that the first supply tube directs fluid into the container in different direction than a direction of the second supply tube.
10. The apparatus of claim 1 , wherein the liquid supply includes a first supply tube and a second supply tube, the first supply tube and the second supply tube are configured so that the first supply tube delivers liquid at a different temperature than that of the second supply tube.
11. The apparatus of claim 1 , further comprising a sensor configured to detect powder flow from the measuring device.
12. An apparatus for preparing within a container a reconstituted beverage from a powder, the apparatus comprising:
a receptacle configured to contain the powder, the receptacle comprising:
a first end having a first dimension,
a second end opposed to the first end, the second end having a second dimension, and
a sidewall connecting the first end and the second end, a portion of the sidewall being angled so as to converge from the first end to the second end, the portion having an angle configured to cause powder bridging at or above the second end;
a measuring device configured to receive powder from the second end of the receptacle, the measuring device further configured to dispense a predetermined amount of powder into the container, the predetermined amount of powder corresponding to a sum of a volume of the measuring device and a volume of powder disposed below a bridge formed by the powder bridging; and
a vibrator configured to vibrate the measuring device to dispense the powder from the measuring device into the container.
13. The apparatus of claim 12 , further including a mixing device configured to mix contents of the container while supporting the container such that a closed base end of the container is disposed at an angle relative to a horizontal angle.
14. The apparatus of claim 13 , wherein the mixing device is configured to mix the contents of the container by rotation of the container about an axis perpendicular to the closed base end of the container.
15. The apparatus of claim 14 , wherein the mixing device is configured to mix the contents of the container by alternating the rotation of the container between opposed rotation directions.
16. The apparatus of claim 12 , further comprising a chute disposed between the measuring device and the container, the chute configured to direct the powder from the measuring device into the container such that a direction of powder flow is changed between the measuring device and the container.
17. The apparatus of claim 12 , further comprising a mixing device configured to mix contents of the container, the mixing device comprising:
a holder configured to secure the container; and
a motor configured to rotate the holder.
18. An apparatus for preparing within a container a reconstituted beverage from a powder, the apparatus including:
a receptacle configured to contain the powder;
a measuring device configured to receive the powder from the receptacle and dispense the powder into the container;
a liquid supply configured to dispense liquid into the container;
a mixing device configured to mix contents of the container while supporting the container such that a closed base end of the container is disposed at an angle relative to a horizontal angle; and
a sensor configured to detect powder flow from the measuring device.
19. The apparatus of claim 18 , wherein the receptacle comprises:
an open receptacle first end having a first dimension;
an open receptacle second end opposed to the open receptacle first end, the open receptacle second end having a second dimension; and
a receptacle sidewall connecting the open receptacle first and the open receptacle second end, a portion of the receptacle sidewall being angled so as to converge from the open receptacle first end to the open receptacle second end, the portion having an angle configured to cause powder bridging at or above the open receptacle second end,
wherein the measuring device includes a tube having a tube first end connected to the open receptacle second end, and an open tube second end opposed to the tube first end, and
the apparatus further comprising a valve disposed between the tube first end and the open tube second end, the valve configured to control powder flow from the open tube second end,
wherein a predetermined amount of powder corresponds to a sum of a volume of the measuring device above the valve and a volume of powder disposed below a bridge formed by the powder bridging.
20. The apparatus of claim 18 , wherein the liquid supply is configured such that a first supply tube delivers liquid at a temperature to pasteurize the reconstituted beverage.
