To provide a device for soaking solid foodstuff in syrup and heating the solid foodstuff with which a large amount of solid foodstuff can be soaked in syrup with excellent heat efficiency in a short time.

The device works as follows: the solid foodstuff (M) such as bean, potato, chestnut or fruit is temporarily stored in a boiling basket (C) for preventing loss of the shape thereof, and thereafter heated in the state of being soaked in the syrup (S) inside a boiling pot (T); the syrup in which the solid foodstuff is soaked, is forcibly fed from the bottom surface (2) of the boiling pot to a syrup discharge nozzle (71) facing the top surface of the boiling pot through a liquid discharge pipeline (59) by a circulation pump (62) installed outside the boiling pot when the sugar content of the solid foodstuff (M) is increased from an initial light syrup condition to a target thick syrup condition; and the syrup discharged from the discharge nozzle (71) is shaken off and diffused to the liquid surface (L-L) of the syrup inside the boiling pot by the rotary centrifugal force of a syrup scattering body (A) to positively accelerate the evaporating action of moisture from the liquid surface (L-L).
