In addition, the above-mentioned rear direction is the conveyance direction of the seaweed K as a to-be-processed object mentioned later, and demonstrates the front end side as an upstream, and a rear end side as a downstream.
First, water is poured into the treatment tank 7 until a part of the impeller 11 of the ripening apparatus 1, the lower surface of the belt conveyor 33 for preventing levitation, and the front end of the discharge belt conveyor 29 are immersed. Next, the burner 6 is ignited to heat the water in the treatment tank 37 to obtain hot water W.

The conveying assist belt conveyor 28, the discharge belt conveyor 29, the draining roller 31, and the anti-lift belt conveyor 33 of the ripening apparatus 1 are driven.
A motor (not shown) is driven to rotate the impeller 11 of the transfer devices 9a and 9b counterclockwise in FIG. The blades 19 of the impeller 11 are driven to rotate so as to repeatedly enter and exit the hot water W in the treatment tank 7. Then, as shown by the arrows in FIG. 4, the blades 19 cause the hot water W to flow from the water surface to the bottom of the treatment tank 7 and to generate a water flow in the transport direction. Since the four blades 19 are arranged at equal intervals, a water flow is generated at regular time intervals.

As shown by the arrow in FIG. 1, the seaweed K as the object to be processed is introduced into the processing tank 7 from between the transfer devices 9 a and 9 b. Next, the water flow in the processing tank 7 sends Wakame K downstream while drawing the seaweed K into the bottom of the processing tank 7.
Since the tip 21 of the blade 19 is bent in the clockwise direction in FIG. 1, that is, in the direction opposite to the rotational direction of the impeller 11, it is possible to prevent the seaweed K from being caught by the blade 19. it can.

Since the lower surface of the belt conveyor 33 for levitation prevention is provided with a space between the bottom of the processing tank 7 and is driven in a state of being immersed in the hot water W in the processing tank 7, the seaweed K is placed on the water surface. There is no floating.
Thus, since the whole seaweed K is immersed in the hot water W until it reaches the discharge belt conveyor 29 after being drawn into the bottom of the treatment tank 7 by the water flow, the seaweed K is removed. Can be boiled uniformly.

The pull-in member 23 draws the seaweed K, which has been removed from the water flow generated by the impeller 11 of the transport device 9b, into the hot water W, puts it on the water flow, and reliably sends it downstream.
Since the portion of the retracting member 23 that is substantially from the center is bent in the same direction as the tip portion 21 of the blade 19, it is possible to prevent the seaweed K from being caught by the retracting member 23.
Further, the seaweed K is more reliably transported by the transport assisting belt conveyor 28.

  Since the endless belt is made of a mesh material as described above, the discharge belt conveyor 29 conveys the seaweed K while cutting the hot water W. Further, the water draining roller 31 cuts the hot water W attached to the seaweed K such that the seaweed K is pressed against the discharging belt conveyor 29. As shown in FIG. 1, the seaweed K falls from the rear end portion of the discharge belt conveyor 29 and is introduced from the left end side of the upper surface opening of the treatment tank 37 of the cooling device 36.

The water flow generated by the impeller 11 of the conveying device 9a that is driven to rotate draws the seaweed K to the bottom of the processing tank 37 and sends it downstream. Further, the water flow generated by the impeller 11 of the transfer device 9b draws the seaweed K again to the bottom of the processing tank 37 and sends it downstream.
In this way, since the entire seaweed K is immersed in the cooling water C from when it is drawn into the bottom of the treatment tank 37 by the water flow until it reaches the discharge belt conveyor 29, the seaweed K The whole can be quickly and uniformly cooled.

  In addition, the drawing member 23 draws the seaweed K, which is out of the water flow generated by the impeller 11 of the transport device 9b, into the cooling water C, puts it on the water flow, and reliably sends it downstream. Similarly, the seaweed K is more reliably transported by the transport assisting belt conveyor 28.

The discharge belt conveyor 29 conveys the seaweed K while cutting the cooling water C, and discharges it to the outside of the processing tank 37.
In addition, the cooling water C in the processing tank 37 is replaced | exchanged suitably, and is maintained at fixed temperature.
As described above, the ripening device 1 and the cooling device 36 can continuously ripen and cool Wakame K. Therefore, each time the processing for one batch is completed, the processing is temporarily interrupted. It is not necessary to take out seaweed or the like from the processing tanks 7 and 37 and put the seaweed K before the processing into the processing tanks 7 and 37.
Further, since the seaweed K is sent to the bottom of the treatment tanks 7 and 37 by the water flow generated by the impeller 11, it is not necessary to manually stir the seaweed K in order to sink it.
