Devices and methods for dosing

A system configured for producing a frozen confectionary, the system comprising:

• a container mount;
• a first container configured to hold ingredients of the frozen confectionary and to be attached to the container mount;
• a liquid doser configured to deliver a cryogenic liquid into the first container, the doser including:
• a reservoir configured to store the cryogenic liquid at atmospheric pressure;
• a first output configured to receive cryogenic liquid and deliver the received cryogenic liquid out of the reservoir and into the first container;
• and
• a first scoop configured to transfer the portion of the cryogenic liquid within the reservoir to the first output, the first scoop configured to move between a first position for receiving the portion of the cryogenic liquid and a second position for dispensing the portion of the cryogenic liquid into the first output.

A method of operating a frozen confectionary production system having a user interface, a reservoir for holding a cryogenic liquid, an output through which cryogenic liquid flows out of the reservoir, and at least one scoop, the method comprising:

• adding a plurality of doses of a cryogenic liquid to a container, the container including ingredients for a frozen confectionary, wherein adding each dose of the plurality of doses includes:
• moving the at least one scoop to a first position in the reservoir to receive cryogenic liquid in the at least one scoop;
• raising the at least one scoop vertically with respect to the reservoir from the first position to a second position;
• and
• dispensing at least a portion of the cryogenic liquid from the scoop into an output port disposed in the reservoir when the scoop is at the second position to provide the dispensed cryogenic liquid into the container;
• and
• mixing the ingredients while adding the plurality of doses of the cryogenic liquid.
