A soup supply apparatus of the present invention is characterized in that, in a soup supply apparatus X that supplies, in fixed quantities, soup that is housed in a hopper through rotation of an inner valve 26 and back-and-forth movement of a plunger 30, an engaging and detaching means 61 is configured by: a cylindrical first engaging body 62 that is provided in a state such as to be fitted outside a lower end portion of an output shaft 14a of a stirring motor and has an engaging portion； and a cylindrical second engaging body 63 that has an engaged portion that is engaged with and detached from the engaging portion and is provided in a state such as to be fitted outside an upper end portion of a vertical rotation shaft. A latera-direction engagement hole 64 that communicates with an insertion hole that is formed in the upper end portion of the vertical rotation shaft is formed in the cylindrical second engaging body. A rod-shaped inserting portion 65b of a lock bolt 65 is inserted into the engagement hole and the insertion hole. When at least a hopper upper lid and the vertical rotation shaft are cleaned, in a state in which a free end portion of an upper-portion housing box of a machine body is lifted upwards and the hopper upper lid is removed from the hopper, the lock bolt is pulled out of the engagement hole and the insertion hole, and the cylindrical second engaging body 63, the vertical rotation shaft 9, and the hopper upper lid 8 can thereby be disassembled. When the hopper upper lid and the vertical rotation shaft that has a stirring blade is cleaned, at least these components (the upper lid and the vertical rotation shaft) can be easily disassembled, and these components can be easily coupled after cleaning as well.
