A continuous-flow electromagnetic-induction fluid heater (1, 1', 1") for a beverage vending machine; the continuous-flow electromagnetic-induction fluid heater (1, 1', 1") comprises: - at least one tubular body internally defining at least one channel for a fluid and including at least one inlet opening through which the fluid to be heated is fed, in use, to said channel , and one outlet opening through which the heated fluid flows out, in use, from said channel ; - a heating element (13, 13', 13") arranged, at least partially, inside said channel so as to be lapped, in use, by the fluid; and - an electric winding wound directly in contact around an external surface of said tubular body and which can be electrically powered to generate an electromagnetic induction field and heat, in this manner, the heating element (13, 13', 13") due to the effect of said electromagnetic induction field; the continuous-flow electromagnetic-induction fluid heater (1, 1', 1") further comprises an upstream fluid baffle , which is housed within said channel in a position fluidically downstream of said inlet opening and fluidically upstream of said heating element (13, 13', 13"), with respect to the direction of the fluid from said inlet opening to said outlet opening , and is shaped so as to reduce the hydrodynamic drag on said fluid between said inlet opening and said heating element (13, 13', 13"). the continuous-flow electromagnetic-induction fluid heater (1, 1', 1") comprises: - at least one tubular body internally defining at least one channel for a fluid and including at least one inlet opening through which the fluid to be heated is fed, in use, to said channel , and one outlet opening through which the heated fluid flows out, in use, from said channel ; - a heating element (13, 13', 13") arranged, at least partially, inside said channel so as to be lapped, in use, by the fluid; and - an electric winding wound directly in contact around an external surface of said tubular body and which can be electrically powered to generate an electromagnetic induction field and heat, in this manner, the heating element (13, 13', 13") due to the effect of said electromagnetic induction field; - at least one tubular body internally defining at least one channel for a fluid and including at least one inlet opening through which the fluid to be heated is fed, in use, to said channel , and one outlet opening through which the heated fluid flows out, in use, from said channel ; - a heating element (13, 13', 13") arranged, at least partially, inside said channel so as to be lapped, in use, by the fluid; and - an electric winding wound directly in contact around an external surface of said tubular body and which can be electrically powered to generate an electromagnetic induction field and heat, in this manner, the heating element (13, 13', 13") due to the effect of said electromagnetic induction field; the continuous-flow electromagnetic-induction fluid heater (1, 1', 1") further comprises an upstream fluid baffle , which is housed within said channel in a position fluidically downstream of said inlet opening and fluidically upstream of said heating element (13, 13', 13"), with respect to the direction of the fluid from said inlet opening to said outlet opening , and is shaped so as to reduce the hydrodynamic drag on said fluid between said inlet opening and said heating element (13, 13', 13"). <EOS>
