摘要： A method for producing a fatty acid ester according to the present invention includes mixing a raw fat or oil, a liquid enzyme, and an alcohol having 1 to 8 carbon atoms in the presence of water and an electrolyte. According to the present invention, a fatty acid ester can be efficiently produced via a transesterification reaction without using any expensive buffer solution or amphipathic substance. Furthermore, in the reaction, it is not necessarily required to agitate reactants at a high speed, which makes the present invention adaptive to various production facilities and conditions.

摘要： 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.
