Abstract: A liquid cooling device that is capable of efficiently cooling a liquid in the inside of a liquid holding container, and a beverage forming device including the liquid cooling device are provided. The liquid cooling device includes the liquid holding container that has an open portion; a container mounting part on which the liquid holding container is to be mounted; an air passage; and an airflow generating unit. The air passage is located directly above the open portion (4b), and at least a part of an outer periphery of the air passage extends along a peripheral edge of the open portion (4b). The airflow generating unit generates, within the air passage, an airflow flowing along the air passage. A hole portion (33) that communicates with the open portion (4b) is provided in a lower surface of the air passage.

Abstract: A disc-shaped stirring element (100A) includes at least one projecting portion (102) at a position on a lower surface (103a) separated from a rotation center, the projecting portion (102) projecting toward a bottom surface (51a) of a stirring container (51), and an upper surface (103b) of the stirring element (100A) is planar.
