Evaporator

An evaporation device including an agitation vessel to which raw material liquid is supplied. The agitation vessel has a volatile component outlet and a concentrate outlet, a jacket provided on an outer circumference and configured to heat an inner wall, and a liquid-distributing portion configured to cause the raw material liquid to flow down the inner wall. The agitation vessel includes storage portion surrounded by a bottom, the inner wall, and a partition wall portion configured to temporarily store the raw material liquid that flows down, the liquid-distributing portion is constituted by a rotating shaft and at least one channel part having a flow passage which, as the rotating shaft rotates, the raw material liquid temporarily stored in the storage portion flows upward from a lower side of the agitation vessel. The channel part is mounted to the rotating shaft, and the concentrate outlet is provided in the bottom.
