The invention discloses quick heating equipment for fluid food. The quick heating equipment comprises a heating furnace body, wherein the heating furnace body is of a cylindrical housing structure; aseparating plate made from a heat conducting material is horizontally and integrally arranged in the middle of a shell cavity of the heating furnace body; a circulating combustion cavity is formed inthe upper side of the separating plate; a heat insulation and liquid storage cavity is formed in the lower side of the separating plate; and a circulating heater is coaxially and fixedly arranged on the inner wall of the circulating combustion cavity. The quick heating equipment is simple in structure; flame sprayed by a flaming port in each flaming blade rotates along with a rotary furnace core,further, the tail end of the flame sprayed by each flaming port continuously sweeps over an entire annular flame groove within a rotation period; the wall on which the annular flame groove is locatedis uniformly and quickly heated; and local continuous asymmetric heating is reduced.
