Description

  The present invention relates to an apparatus for continuously steaming a shochu brewing material 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 pregelatinized 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, the temperature of the frozen raw material is low near the steaming start section, so the steam is discharged as hot water and discharged outside the apparatus. A large amount of steam loss occurred compared to the device.

  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.

Japanese Patent Laying-Open No. 2006-174986 (paragraph “0016”, lines 5-6, FIG. 6B)

  An object of this invention is to obtain the continuous steaming raw material cooling device with quick cooling after steaming raw materials, such as sweet potato.

In order to achieve the above object, the present invention supports a laminated raw material on a breathable conveyor that moves in the machine box, and forms a cooking chamber by piping a steam jet pipe on the upper portion of the raw material. The cooling water jet pipe is provided above the laminated raw material, the cooling water jetted from the jet pipe is supplied to the raw material, and the upper part of the cooling water jet pipe is connected to the atmosphere so that the cooling water adheres to the raw material. Continuous steaming formed so that the laminated raw material can be blown by the cooling air discharge suction blower provided in the cooling water collecting part, the cooling water adhering to the raw material is vaporized, and the latent heat of vaporization is taken to the atmosphere. Raw material cooling device,
Consists of.

  Therefore, after the laminated raw material (sweet candy particles) on the upper transition part of the breathable conveyor has passed through the cooking chamber, the mist or shower that is ejected from the cooling water jetting part moves the laminated steamed raw material from top to bottom in the cooling part at the rear. Passing water evaporates and the adhering water evaporates, and the latent heat of vaporization is taken to the atmosphere, so the laminated material is cooled in a short time.

Since the present invention is configured as described above, even if the laminated raw material cooked in the steaming room is deprived of the latent heat of vaporization in the cooling section, it can be cooled in a short time even when low temperature fermentation is required in the summer or when shochu is charged. There is an effect of obtaining a continuous steaming raw material cooling device that can be performed.
