An apparatus for preparing baby milk from water and dry formula includes a formula supply system having a reservoir for holding formula and a feeder for feeding formula out off the reservoir through an outlet opening in the reservoir. The apparatus further includes a scraper for guiding formula towards and through the outlet opening into the feeder. The scraper is arranged to move closely along an inner wall portion of the reservoir that borders on the outlet opening.

1. An apparatus for preparing baby milk from water and dry formula, the apparatus comprising: a water supply system for supplying water;a formula supply system for supplying the dry formula, wherein the formula supply system comprises a reservoir for holding the dry formula, a feeder for feeding the dry formula out of the reservoir through an outlet opening in the reservoir, and a scraper configured to guide the dry formula towards the outlet opening in the reservoir; anda mixing unit for bringing the water and the dry formula together,wherein the scraper is further configured to move closely along an inner wall portion of the reservoir that borders on the outlet opening,wherein the outlet opening is elongated and extends across the inner wall portion substantially from a center of the inner wall portion to an edge of the inner wall portion,wherein the scraper comprises at least two arms that are rotatable around a rotation axis extending substantially perpendicular to a longitudinal axis of the reservoir,wherein the at least two arms are curved and have free ends that curve away from the walls towards a center of the reservoir, andwherein the free ends terminate with extremities that do not contact each other and, in one rotable position of the scraper, extend along a direction parallel to the longitudinal axis of the reservoir. 2. The apparatus according to claim 1, wherein the outlet opening is located eccentric with respect to the rotation axis of the scraper. 3. The apparatus according to claim 1, wherein the curved arms are biased in the rotation direction. 4. The apparatus according to claim 1, wherein the inner wall portion, along which the scraper move closely during use, is curved in two directions to trace a spherical volume. 5. The apparatus according to claim 1, wherein the scraper is further configured to rummage a three dimensional space during rotation including a sphere or spheroid. 6. The apparatus according to claim 1, wherein the scraper has a three-dimensional shape. 7. The apparatus according to claim 1, wherein the feeder is configured to have a transport direction that slants upward from the outlet opening of the reservoir for feeding the dry formula out of the reservoir in the transport direction. 8. The apparatus according to claim 7, wherein an angle between the transport direction of the feeder and the horizontal plane lies at least one of between 10 and 70 degrees, and between 30 and 50 degrees. 9. The apparatus according to claim 1, wherein the formula supply system comprises indicator configured to indicate that an amount of formula in the reservoir has reached a predetermined level. 10. The apparatus according to claim 1, wherein the outlet opening is provided in or near a bottom of the reservoir and an inner surface of said bottom has a convex shape. 11. The apparatus of claim 1, wherein a first extremity of the extremities extends in a first direction and a second extremity of the extremities extends in a second direction which is opposite to the first direction. 12. An apparatus for preparing baby milk from water and dry formula, the apparatus comprising: a water supply system for supplying water;a formula supply system for supplying the dry formula, wherein the formula supply system comprises a reservoir for holding the dry formula, a feeder for feeding the dry formula out of the reservoir through an outlet opening in the reservoir, and a scraper configured to guide the dry formula towards the outlet opening in the reservoir; anda mixing unit for bringing the water and the dry formula together,wherein the scraper is further configured to move closely along an inner wall portion of the reservoir that borders on the outlet opening,wherein the outlet opening is elongated and extends across the inner wall portion substantially from a center of the inner wall portion to an edge of the inner wall portion,wherein the scraper comprises at least two arms that are rotatable around a rotation axis extending substantially perpendicular to a longitudinal axis of the reservoir,wherein the at least two arms are curved and have free ends that curve away from the walls towards a center of the reservoir,wherein a first extremity of a first arm of the at least two arms extends in a first direction and a second extremity of a second arm of the at least two arms extends in a second direction which is opposite to the first direction,wherein, in one rotatable position of the scraper, the first direction and the second direction are parallel to the longitudinal axis of the reservoir, andwherein the at least two arms form an open loop where the first extremity does not contact the second extremity.
