Description

  The present invention relates to an apparatus for continuously steaming and thawing raw materials for shochu brewing such as sweet potato in a conventional manner, and subsequently cooling it.

  Conventionally, the cooking chamber and the cooling chamber in the machine box are partitioned by an air curtain that flows down from the pressure adjustment chamber, and is moved intermittently from the start end to the end by a single breathable movable floor, and is steamed and cooled from the end opening. A device for discharging raw sweet potato particles out of the machine and performing continuous steaming has been developed (for example, Patent Document 1).

  In the steaming chamber, the surplus steam that has passed through the stacked raw materials is discharged from the lower discharge path through the drain by the blower to the outside of the machine.

  Thereafter, the sweet potato particles were cooled to an appropriate temperature by cold air blown from a cold air pipe provided separately on the ceiling side.

  Therefore, in the steam chamber, since the temperature of the raw material is low near the steaming start part, the steam becomes hot water and is discharged out of the machine. A large amount of steam loss occurred.

  In addition, since the cooling unit was air-cooled by air blowing or suction, it took time to cool the steamed raw material in summertime when the outside air temperature was high or when low-temperature fermentation was required in shochu preparation.
