Abstract: A liquid food heating apparatus includes: a steam jet nozzle (36), a nozzle holder (18) to which the steam jet nozzle (36) is attached; a steam feed pipe (17), nozzle coupling means (14a, 14b, 14c) capable of coupling the steam jet nozzle (36) attached to the nozzle holder (18) to the steam feed pipe (17), and nozzle discard means (12b, 12c, 12d, 18c) capable of detaching from the nozzle holder (18) the steam jet nozzle (36) attached to the nozzle holder (18) and discarding the nozzle. The nozzle discard means detaches from the nozzle holder (18) the steam jet nozzle (36) attached to the nozzle holder (18) and discards the nozzle after releasing the coupling between the steam jet nozzle (36) attached to the nozzle holder (18) and the steam feed pipe (17).
